[0:27] <brianx> Psi-Jack: i found yzf600's answer in the link but there isn't enough to say much more about how to do this. if the pwm is really being looked at by the controller then you can simply generate the correct pwm in software and use one gpio with a transistor to output the right results to the main door controller. it could all live inside the main controller where there is plenty of power and access to
[0:27] <brianx> those handy door open/close signals (or you could do the magnet thing as shown in one of the related links from your link)

[0:54] <brianx> you may have to examine the controller board to be sure, or just mock something up and try it. the thing has to be bulletproof to handle the main switch shorting it out so you probably can't harm it with anything you do using the two wires and not injecting some high voltage into them.
[0:55] <Psi-Jack> Hmmm, indeed. I actually considered that very idea of just plugging up stuff to a breadboard, and using some kind of reasonably safe means to jump over them.
[0:57] <brianx> the door switch is the easiest obviously.
[0:57] <brianx> you'll need a transistor regardless.
[0:58] <Psi-Jack> Yeah. I'm pondering checking to see which si correct. RadioShack's site, or Google Maps, to whether there are actually Radio Shack's in my city. LOL
[1:00] <hummocks> radio shack's what ?
[1:00] <Psi-Jack> Hmm, even Apple maps shows RadioShack as well.
[1:00] <Psi-Jack> hummocks: Used to be a pretty awesome components and electronics store.
[1:01] <brianx> you need the scope captures befor making a good guess at the appropriate circuit.
[1:01] <Psi-Jack> Now, it's still kinda got that, but less on the components, more on the crap electronics. Though, they still have resistors, capacitors and transitors and the likes usually.
[1:01] <hummocks> sounds like maplins
[1:02] <Psi-Jack> Course, if you want GOOD Capacitors that aren't badly QA'd Chinese ones, definitely don't go to Radio Shack. :)
[1:02] * ssvb (~ssvb@dsl-espbrasgw1-54fa71-124.dhcp.inet.fi) has joined #raspberrypi
[1:02] <brianx> to use a single gpio and just control the line directly, you'll need to sense the line too.
[1:02] * IT_Sean (~quassel@applefritter/IRCStaff) Quit (Remote host closed the connection)
[1:02] <Psi-Jack> brianx: Hmm. Well, I have that ordered at least. Probably get here Monday... Tuesday at the latest.

[1:15] <Psi-Jack> Man... This is how bad Radio Shack has gotten. Searching for oscilloscope in their products listing... Results in breadboards, headphones, HDMI to RCA converters, AM/FM radios. None of which has anything to do with an oscilloscope.

[1:17] <Psi-Jack> Now, Fry's Electronics, on the other hand.. They have oscilloscopes ranging from $312 to $1500, right off the bat. It's a pitty there's none of those around here.
[1:19] * eliudnir (~eliudnir@c-107-3-149-111.hsd1.ca.comcast.net) Quit (Quit: ZNC - http://znc.in)
[1:19] <brianx> yeah, I'm going to miss microcenter and frys when i move.
[1:19] * Maxxed (~root@ec2-107-20-252-119.compute-1.amazonaws.com) has joined #raspberrypi
[1:19] * eliudnir (~eliudnir@c-107-3-149-111.hsd1.ca.comcast.net) has joined #raspberrypi
[1:20] <Psi-Jack> Yeah.. I already long since miss Fry's. Used to live in Austin, TX, where they had a very good full sized one. :)
[1:20] <Maxxed> i've been banging my head on my desk.. for somereason, if i scp a big file from my pi to my laptop (over wifi) it starts off fast, then slowly dies out
[1:20] <Maxxed> any ideas?
[1:20] * agusyc (~agusyc@ Quit (Remote host closed the connection)
[1:20] <Psi-Jack> Maxxed: Crappy WAP?
[1:21] <Maxxed> nah, tried 2 diff ones, like sitting at my desk
[1:21] <Psi-Jack> That doesn't mean much. :)
[1:21] <Maxxed> disabled that power saver stuff on the pi too
[1:21] * Vonter (~Vonter@ has joined #raspberrypi
[1:21] <Maxxed> the pi has plenty of juice too, got a 5v 5amp supply on it
[1:22] <Maxxed> tried diff channels on the ap too, thinking interference, same result
[1:22] <Psi-Jack> That was your first problem, randomly changing channels. To what?
[1:22] <Psi-Jack> Only three channels on 2.5GHz matters. 1, 6, and 11.
[1:22] <Maxxed> strange to see the latency spike thru the roof too, like 1-2sec round trip (ping)
[1:23] <Maxxed> tried em, and auto chan too, same result, im thinking i can rule out interference
[1:23] <Psi-Jack> No, you really can't.
[1:23] <Maxxed> as the pi acts fine, until i try to saturate the link with scp
[1:23] <Maxxed> well, not with out a spectrum analyser
[1:24] <Maxxed> but everything else on the wap seems to be fine
[1:24] <Psi-Jack> Well, there's a simple WiFi Scan you can do too. :p
[1:24] <Maxxed> i want to rule out the wap really..
[1:24] <Maxxed> well yeah ;)
[1:24] <Maxxed> just poking in here to see if you guys know of anything off hand that i might be missing
[1:24] <Psi-Jack> But, not just WiFi. My UniFI AP's actually scans for WiFi and other potential interfering radio traffic, including satallite and microwave.
[1:25] <Maxxed> i would think i could squeek at least 10mbits a sec out of it
[1:25] <Psi-Jack> 10mbits? That's... Horrible.
[1:25] <Maxxed> yeah, those unifi's are awesome
[1:25] * eliudnir (~eliudnir@c-107-3-149-111.hsd1.ca.comcast.net) Quit (Quit: ZNC - http://znc.in)
[1:25] <Maxxed> yeah, im not getting crap
[1:25] <Maxxed> next step, put both the wap and the pi in a farady cage and see wtf i guess :p
[1:25] * eliudnir (~eliudnir@c-107-3-149-111.hsd1.ca.comcast.net) has joined #raspberrypi

[1:26] <Maxxed> i wish i could see that kinda action :p
[1:27] <Maxxed> anywho, im going to keep at it
[1:27] <Maxxed> i'll shout out in here what i find :)
[1:27] * brainzap (~brainzap@46-126-143-230.dynamic.hispeed.ch) Quit (Quit: IRC client 0x7ffff85f21cce has value 0x20ec8348 which is neither locked or unlocked. The memory has been smashed.)
[1:28] <Psi-Jack> Oh 802.11ac I can easily sustain 400Mbit, long term. On N, definitely near 300, depending on whether it's on 2.5GHz or 5GHz.
[1:29] <Psi-Jack> Generally anything faster would require bandwidth-sucking multi-radio WNICs, though, to which I don't use any.
[1:31] <Psi-Jack> I used to use an ASUS AC66U. I got crappy speeds and crappy range no matter what I did. I've had a Cisco AP, 3Com AP, Engenius AP, Linkcrap AP. They all sucked.
[1:32] * redfire (~redfire@cpe-24-209-107-137.cinci.res.rr.com) has joined #raspberrypi
[1:35] <Psi-Jack> Oh, and definitely never ever ever use auto mode on WiFi. That's always going to be stupid on the AP's point of view.
[1:36] <brianx> so how are you selecting channel if not auto? conditions change regularly.
[1:36] <Maxxed> +1
[1:37] <Psi-Jack> brianx: You scan. And know how WiFi works, and what channel bands are used.
[1:38] <brianx> scans today are not very accurate next week.
[1:38] <Psi-Jack> For example, if you're in a highly condensed residential area, especially like an apartment complex with 2+ floors, don't use 40MHz, 80MHz, etc.. Use the lower MHz levels, you'll still get reasonable speed, but you'll interfere less with your neighbors and thus, get better throughput if you work with them. ;)
[1:40] * bgd (~bgd@2a02:a03f:2c73:2c00:7408:823e:6f68:a1b0) has joined #raspberrypi
[1:40] * holodoc (~holodoc@unaffiliated/holodoc) Quit (Ping timeout: 240 seconds)
[1:41] <brianx> assuming not everyone is doing the same thing.
[1:41] <Psi-Jack> It's really just a matter of understanding how it works, and again, when needed, talk to your neighbors to establish the best possible solution to WiFi issues. :)
[1:42] <Psi-Jack> I live in a house, so the range between me and my neighbors barely has any interference, so in that regard, I'm kinda lucky. ;)
[1:42] <brianx> lol, in one of my networks, there are over 100 ssids visible.
[1:42] <Psi-Jack> Yikes!
[1:42] * squelch (~squelch@ has joined #raspberrypi
[1:42] <Psi-Jack> Yeah. Situations like that...... I'd just try to find the best channels, and hope for the best.
[1:42] <brianx> yeah. and i do think auto ends up being 1.
[1:42] <Psi-Jack> Yep.
[1:43] <Psi-Jack> Most times, auto starts at 1.
[1:43] <brianx> so auto agrees with you.
[1:43] * holodoc (~holodoc@unaffiliated/holodoc) has joined #raspberrypi
[1:43] <Psi-Jack> Or 36, for 5G
[1:43] <brianx> that net is only 2.4
[1:43] <Psi-Jack> 1, 6, and 11 for 2GHz is the best, without any overlapping frequencies, at 20MHz.
[1:44] <brianx> i only irc over it.
[1:44] <brianx> rare light browsing.
[1:44] <Psi-Jack> Once you apply 40MHz, channel 1 will intefere with channel 6, 6 with both 1 and 11, and 11 will interfere with 6.
[1:45] <brianx> i think it's set to 20, 40 was slower. tested long ago, so not 100% sure.
[1:46] <Psi-Jack> The 5G range you /can/ go to 40MHz, but you won't take advantage of it with most standard wNICs, because they only have 1 radio.
[1:46] <brianx> 4x4 on the only client i use that isn't esp8266
[1:47] <Psi-Jack> And 5GHz has more channels, thus more bands, and less overlap.
[1:47] <Psi-Jack> Heh. Sheash. 4x4 on a WNIC?
[1:48] <brianx> cellphone.
[1:48] * nidzo_ (~Nidzo@ has joined #raspberrypi
[1:48] <brianx> the unifi is only 3x3 though
[1:48] <Psi-Jack> Yeah.
[1:49] <brianx> i think the lite is 2x2
[1:49] * kw21 (~kw21@D978E830.cm-3-1d.dynamic.ziggo.nl) Quit (Ping timeout: 240 seconds)
[1:49] <Psi-Jack> Correct
[1:49] <Psi-Jack> The Pro is the one that has 3x3
[1:49] <Psi-Jack> The Lite and LR have 2x2
[1:50] <brianx> one of the reasons to go with pro. the weather resistance was another.
[1:50] <brianx> real poe too.
[1:50] <Psi-Jack> Heh yeah.
[1:51] <Psi-Jack> I didn't need real PoE, or placing them outside. Now that I have my UAP-AC-Lites, I'm more than happy considering what I had.
[1:51] <brianx> i got an open box so it was only $15 extra
[1:51] <brianx> so, does it have 802.11r? or are you using zero handoff?
[1:52] <Psi-Jack> brianx: 802.11r is not yet there, however, it's in beta now.
[1:53] <Psi-Jack> It's just a firmware update away to get it. :)
[1:53] <Psi-Jack> Hmmm, it may even already be there, just need to check changelogs.
[1:53] <brianx> oh, great. i had trouble finding if it was supported.
[1:54] <Psi-Jack> I'm checking. But ooooh
[1:54] <Psi-Jack> New firmware does have jq built-in for json parsing. :D
[1:55] <brianx> not sure why I'd want json parsing.
[1:55] * busybox42 (~alan@balerion.evil-admin.com) Quit (Quit: WeeChat 1.7)
[1:55] <Psi-Jack> hehe
[1:56] <brianx> r is important once you have more than 1 ap.
[1:56] <Psi-Jack> And I do.
[1:56] <Psi-Jack> Though, I have not dropped from WiFi since having the 2.
[1:56] <brianx> i know. i don't, yet.
[1:56] <Psi-Jack> 802.11w is supported now.
[1:57] <Psi-Jack> 802.11x is too.
[1:57] <Psi-Jack> Aha!
[1:58] <Psi-Jack> 802.11r is supported since
[1:58] <brianx> oh, great.
[1:58] <Psi-Jack> :)
[1:59] <brianx> and explains why you get no drops without configuring zero handoff.
[1:59] * squelch (~squelch@ Quit (Ping timeout: 240 seconds)
[1:59] <Psi-Jack> Indeed :)
[2:00] <Psi-Jack> And there's been new firmware as of 2017-03-28, which I'm not on yet. heh
[2:01] * de-facto (~de-facto@gateway/tor-sasl/de-facto) Quit (Quit: See you around.)
[2:01] * de-facto (~de-facto@gateway/tor-sasl/de-facto) has joined #raspberrypi
[2:01] <Psi-Jack> I don't turn on auto-firmware updates because, PoE. Better safe than sorry.
[2:02] <Psi-Jack> Though... I possibly could. The PoE router is on an APC.... But still.
[2:02] * pepee (~pepee@unaffiliated/pepee) has joined #raspberrypi
[2:02] * phinxy (~tehhhd@unaffiliated/phinxy) Quit (Quit: Leaving)
[2:02] <brianx> i did the update a few days ago.
[2:03] <Psi-Jack> I.. Somehow missed that update for some reason. Dunno how... I got these AP's on the 27th.

[2:06] <brianx> mine came on the 30th
[2:06] <Psi-Jack> Eh, well, wierd anyway for me. I started using UniFI Controller 4.x the "stable", but I upgraded to 5.x.
[2:07] <Psi-Jack> Well, they're updated now anyway...
[2:08] <brianx> good
[2:08] * jkridner (~jkridner@pdpc/supporter/active/jkridner) has joined #raspberrypi
[2:09] <drjam> havent tried the OS controller yet, i have 2 cloud keys
[2:09] <brianx> i didn't look at 4.x. went right to 5
[2:09] <drjam> holy smoke i hate their guts, but love them too
[2:09] <Psi-Jack> Hmm?
[2:09] <Psi-Jack> I've been considering getting one of their cloud keys.
[2:10] * Noldorin (~noldorin@unaffiliated/noldorin) has joined #raspberrypi
[2:10] <brianx> the er-x is so cheap, it may be in my future.
[2:10] <Psi-Jack> Heh. I have one of those.
[2:11] <Psi-Jack> I just upgraded from the ER-X to the ERPOE-5. :)
[2:11] <brianx> the 3b is my firewall.
[2:11] <Psi-Jack> There's 2 problems with the ER-X. But everything else is great.
[2:12] <Psi-Jack> It does have some issues with offloading, specifically IPsec offloading is bugged. And the internal storage memory is so low that you can't do much with it. If you even so much as try to download the debian apt repo database, you will fill it up.
[2:12] <brianx> going well, have just finished full unbound and ics-dhcp integration.
[2:13] <Maxxed> well fuck me in the ass with a cactus, everything is working fine "all of the sudden"
[2:13] <Maxxed> i guess some wicked interference or something was going on
[2:13] <brianx> ouch. gotta mount a usb drive i guess
[2:14] <Maxxed> going to do some more poking around, but im thinking interference
[2:14] <Psi-Jack> Maxxed: Ahem... Kindly mind the language, please?
[2:14] <Maxxed> ah, excuse me, i forget some folks dont care for that kind of noise
[2:14] <Maxxed> well thanks for the pointers Psi-Jack, im going to do a little more digging, but i think im ok for now :)
[2:14] <Psi-Jack> Well, this channel specifically does have a language policy.
[2:15] <Maxxed> even more reason to be mindful :)
[2:15] <Maxxed> anywho, im out for now, you guys have a great weekend! :D
[2:15] <Psi-Jack> Hmmm...
[2:15] <Psi-Jack> Looks like I'll be getting that scope kit Sunday. :)
[2:15] <brianx> fast
[2:15] <Psi-Jack> I'll have to assemble it, but that should take like an hour.
[2:16] <Psi-Jack> brianx: All about the Prime. :)
[2:16] <brianx> ahh, i get much of my components on aliexpress.
[2:16] * busybox42 (~alan@balerion.evil-admin.com) has joined #raspberrypi
[2:17] <Psi-Jack> Heh, I look on their site to get ideas sometimes, but go to Amazon because they're usually a little cheaper, and definitely usually faster.

[2:18] * SkyFire (~SkyFire@d53-64-214-238.nap.wideopenwest.com) Quit (Quit: Leaving)
[2:19] <brianx> faster, but amazon always loses, usually several fold.
[2:19] <Psi-Jack> How so?
[2:20] <brianx> they win on price.
[2:22] <Psi-Jack> One thing I did with Amazon once that surprised me. I used to live in a city that had LaserShip. I was very uncomfortable with a carrier using a personal vehicle and no uniform at all to deliver my packages to me.
[2:23] <Psi-Jack> They were also late by a day to two days on average. So I got a network attached camera and started recording the days they would ship me a package.
[2:23] * teepee_ (~teepee@unaffiliated/teepee) has joined #raspberrypi
[2:24] <brianx> and what did you catch?
[2:24] <Psi-Jack> Turns out they were found throwing packages from there vehicle to the front door one two out of the occasions.
[2:24] <Psi-Jack> On two..

[2:27] <Psi-Jack> They never used them again since
[2:28] <brianx> surprising they listened. most companies can't change their practices for one account.
[2:29] <Psi-Jack> heh
[2:30] <Psi-Jack> I know. They sure did listen though. ANd I wasn't rude with them when I told them the situation. But I definitely did request specifically to talk to a manager to make absolute sure the details were noted on my account.
[2:31] <Psi-Jack> So, how does Amazon lose? :p

[2:42] <Psi-Jack> Oooh, sheash. aliexpress is indeed fairly cheap. They have the WEMOS D1 mini Pro for $5.50
[2:43] <brianx> likely a clone of course.
[2:44] <Psi-Jack> I usually don't mind stuff like that. I mind that it works as expected, and doesn't come damaged. heh
[2:44] <Psi-Jack> I mean, the whole thing is an open platform. No such thing as a clone in that sense.
[2:46] <Psi-Jack> I am curiously excited about one thing though. Z-Wave recently announced a new update to their protocol and SDK v2. Finally implementing actual genuine security (hopefully), involving private keys and public keys on every device, rather than their horrible home-based broken model that they had.
[2:49] <Psi-Jack> But hmm yeah. The AliExpress Wemos D1 Mini Pro doesn't even have the shielded ESP8266EX chip.

[2:53] <brianx> oh, i've had nothing but trouble with dx. i have only used them a couple times but won't again.
[2:54] <Psi-Jack> I ordered from them once, and only once. Never again after that. For me, I just got some cheap little BT dongles that were supposed to be 4.2 BLE capable, they weren't. Those came within 40 days. But I'd ordered something for a friend of mine as a gift from me. An iPhone 30-pin cable with outputs to RCA composite. It took them 2.5 years to finally ship it.
[2:54] <Psi-Jack> And when it did arrive, not only did my friend no longer have the iPhone, but he did test it out, and it didn't even work.
[2:56] <brianx> my long term average for aliexpress is 26 days.

[3:02] <brianx> more on other somewhat related things like the zeros and 3bs.
[3:03] <Psi-Jack> Amazon did deliver a few things faster than I planned and specifically tried to aim for. My Echo Dot,for example, arrived 2 days before her departure, and my iHome replacement alarm clock the day before. heh
[3:03] <brianx> the wifi doesn't go on those numbers because that's household utilities.
[3:03] <Psi-Jack> But everything else... Right on time as planned. LO>
[3:03] <brianx> you're going to get the riot act read when she gets home :-p
[3:04] <Psi-Jack> Ohhhhh yeaaah.
[3:04] <Psi-Jack> But that's okay, because it'll be all at once, and she can't say much because I personally paid for it. :)
[3:04] <brianx> i've got all orders on hold before the move. i want to make sure to be around for delivery.
[3:05] <brianx> out of family funds!! lol :-p
[3:05] <Psi-Jack> hehe
[3:05] <brianx> mine says nothing.
[3:05] <Psi-Jack> Mine'll learn... :)
[3:05] <brianx> but i also say nothing about her hobby and she spends many many times what i do.
[3:06] <Psi-Jack> heck, I'm just happy I get to finally use things I've had for years, barely ever used, but wanted to. My variable temperature soldering station for example. Used it like twice before, and that's it. In the past 2 weeks, I've used it multiple times.
[3:07] <Psi-Jack> And, I'm going to be using the heck outta it Sunday when my scope kit comes in, to assemble it
[3:07] <Psi-Jack> It's the little things that sometimes matter. :)
[3:09] <brianx> i still use my 50 something year old soldering iron.
[3:09] <Psi-Jack> hehe
[3:09] <brianx> still does the job. i do a few smt devices with it even.
[3:10] <brianx> i keep uncoated copper tips for it too, so when i want to do detail work i take it to the drill press, chuck it up and file a nice sharp point on it.
[3:10] <Psi-Jack> Yeah. Mine has variable temp and multiple good quality tips. Was a steal of a deal for it. I like it because I primarily use silver-bearing solder, and that, once you get the temperature just perfect, making those solder joints is a breeze.
[3:11] <brianx> mine was a steal. the handle was free and the element was a couple bucks from the radio shack that i could walk to.
[3:11] <Psi-Jack> Yeah, I have a radio shack iron too.
[3:12] <brianx> the handle isn't. just the element.
[3:15] <Psi-Jack> Mine is a Stahl Tools SSVT. Bought it at $20, now it's $25, got the 4-pack tips for it for $10. Those are $11 now.

[3:22] <brianx> not easily from linux.
[3:23] <brianx> the problem is the timing on most led strips is too tight and preemptive multitasking gets in the way.
[3:24] <brianx> the ws2801 is clocked instead of timed so it handles it better.

[3:43] <brianx> there are nearly infinite options. the apa102 is clocked and therefore probably reasonable to control from linux.
[3:46] <brianx> the reason i don't directly control the ws2801 is the 5V signal requirement. it is also clocked and not very timing sensitive.

[4:40] * Vonter (~Vonter@ Quit (Quit: leaving)
[4:40] <Psi-Jack> Heh, iiiinteresting.
[4:41] <Psi-Jack> brianx: So I adjusted the original schematic to use a 80Hz pulsing 16V power source, changed the switches to push switches, an can see the faltsad scope on what it does, and it's rather interesting.
[4:42] <Psi-Jack> It's not a square pattern they generate, but a fade pattern, basically timing.
[4:43] <Psi-Jack> It's basically a decay pattern.
[4:44] <brianx> and the decay is probably detected in their controller with a comparator at some threshold voltage.
[4:44] <Psi-Jack> Yep yep. That's what it would seem.
[4:45] <brianx> the output of that comparator would be a square wave again, but with a pulse width different from the one being delivered to the switch.
[4:45] * hydrogen (~hydrogen@amarok/developer/hydrogen) Quit (Remote host closed the connection)
[4:45] <brianx> so, no buttons pushed pretty much gives no signal.
[4:45] * Kerr-A (~Kerr-A@ has joined #raspberrypi
[4:46] <brianx> resistor button pushed gives square wave matched to the left wire.
[4:46] <Psi-Jack> Basically just powers the LED.
[4:46] <Psi-Jack> Yeah, the S1 button makes a huge jump square wave.
[4:47] <brianx> little cap gives square wave starting about the same time as the square wave sent but of a shorter duration.
[4:47] <brianx> big cap gives square wave starting about the same time as the square wave sent but of a longer duration.
[4:47] <brianx> than the little cap
[4:48] <brianx> if you feed a square wave in that matches the output of the comparator, it won't know the difference.
[4:49] <brianx> so their decaying pattern can be emulated with nice crisp square waves (easy to make) from your computer controlled button simulator.
[4:50] <brianx> you do probably have to sync up to their square wave, so you probably have to read their square wave with a 2nd gpio used as an input.

[4:55] * j4ckcom (~moretz@unaffiliated/j4ckcom) has joined #raspberrypi
[4:59] <Psi-Jack> I also wonder if it's not a square wave, but a pulse wave, at 80Hz, max voltage of 8, offset of 8 to give it that 16V during the pulses which happen so rapidly.
[5:00] <brianx> i expect it is a positive only signal.
[5:03] <brianx> what are the capacitor sizes?
[5:03] <Psi-Jack> 1uF and 22uF
[5:04] <Psi-Jack> Now, as expected, the S1 garage door switch completely turns off the LED while it's pressed.
[5:06] <Psi-Jack> S2, the lock button, causes the LED to flicker rapidly while held down. Once released and the lock is engaged, it pulses the LED.
[5:06] <Psi-Jack> Lastly, the S3 button, dims the LED a little bit while held down, but retains being lit constantly otherwise.
[5:08] <brianx> all consistent with our expectations. s2 must be the small capacitor
[5:08] <brianx> the only thing confusing is why such a big resistor on that LED.
[5:08] <brianx> what is the value? 1.6K or 160 ohms?
[5:09] * unpelado (~monitoreo@ has joined #raspberrypi
[5:09] <Psi-Jack> 1.6k
[5:09] * rikk (~rikk@unaffiliated/rikk) Quit (Quit: Leaving)
[5:09] <unpelado> hi, I'm having some issue with the reboot command. I connect trougth ssh to my pi, then send the command 'sudo reboot', but it seems that nothing happen. If i try to ssh from another terminal in my pc, i get ssh connection refused, if I Ctrl-c in the terminal window in wich i had ssh'd (where i typed sudo reboot) i get back to prompt, but raspi doesnot seems to have rebooted)
[5:09] <Psi-Jack> I also just adjusted the resistor on the other side by the ground to match that, and guess what.. Almost square waveforms just like the guy described on that posting I referenced earlier.
[5:10] <Psi-Jack> At least for the 22uF. The 1uF still makes a sharp decay.
[5:10] <brianx> with the output connected directly to ground (can't be), the current in the led is only 8.5mA
[5:12] <brianx> put 100 on the left and 56 on the right and you get some nice looking and easy to distinguish curves.
[5:12] <Psi-Jack> Maybe the 1.6k resister is /always/ used no matter what..
[5:13] <brianx> yes, the 1.6k is always in circuit.
[5:13] <brianx> but it leaves you with such a dim led. only 8.5 mA
[5:13] <Psi-Jack> Definitely. I removed the one from the LED, and definitely seems more accurate.
[5:14] <brianx> you need something in there. the led needs a current limit.
[5:14] <Psi-Jack> Oh, it's getting it just before grounding.
[5:15] <Psi-Jack> And it's a very small LED, too, to note.
[5:15] <brianx> 680 ohms gives a nice 17mA compromise between nice and bright and low enough current that a 20ma LED will last a very long time.
[5:15] <Psi-Jack> Not an SMD, but smaller than I guess the "typical" LED size.
[5:15] <brianx> oh, so that's why the small current.
[5:15] * swift110 (~swift110@unaffiliated/swift110) Quit (Ping timeout: 246 seconds)
[5:16] <Psi-Jack> Could be! :)
[5:16] <brianx> so, 1.6k.
[5:16] <brianx> 8.5ma out of a 10ma led.
[5:16] <brianx> a current low enough to give a very long life on the led.
[5:16] <brianx> put 100 on the left and 56 on the right.
[5:17] <brianx> nice waves. 3 easy to distinguish patterns.
[5:20] <brianx> toss a 4.9v zener in parallel to the 56 ohm to ground and you get a TTL compatible output.
[5:20] <brianx> the gate itself could be the comparator. the signals are natively soooo different that the built in threshold in every gate is enough.
[5:21] <Psi-Jack> Heh, yeah, but where are you getting the 100ohm and 56ohm from?
[5:22] <brianx> i played with the ratio until i got pretty signals.
[5:22] <Psi-Jack> LOL
[5:22] <brianx> then i lowered the 1.8 to 1 to the closest standard values needed to bring the signal close to ttl levels.
[5:23] <brianx> then i tacked in the zener to clip to actual ttl levels.

[5:49] <brianx> Psi-Jack: did you refresh the ghostbin and get the new circuit?
[5:49] <Psi-Jack> Yes
[5:49] <Psi-Jack> I'm also re-rebuilding the curcuit based on the board itself.
[5:50] <Psi-Jack> One thing I noticed on the actual board... One peg of the 22uF cap connects to one pin of the 1uF cap.
[5:50] <brianx> oh, good. i didn't know you had any portion of the controller's circuit.
[5:51] <brianx> yes. that's the case on the circuit i sent. last time i had a 1 pico ohm resistor in there to keep the simulator happy when you accidentally close both switches at the same time.
[5:51] <brianx> i just made the switches more realistic now. it does the same thing.
[5:52] <jaziz> yoooo it worked
[5:52] <jaziz> nice
[5:52] <jaziz> thanks
[5:52] <jaziz> why was that info so hard to find online
[5:53] <brianx> well, this is just the existing system. or best guess at it. assumes chris Stratton's guess is right.
[5:54] <brianx> but, if this is really right then you can emulate it with a square wave of your own.
[5:59] <Psi-Jack> Hah!
[5:59] <Psi-Jack> I think I got this!

[6:01] * feksclaus (~feksclaus@80-71-131-204.u.parknet.dk) has joined #raspberrypi
[6:01] <Psi-Jack> It seems REALLY potential, as when you flip S1, it shorts out the connection, which would in turn, turn off the LED which also opens the garage door (I have shorted it accross and it does open every time, along with trying to measure mA with the multimeter at the two screws, it opens the garage that way too, shorting it)
[6:01] * choki (~weechat@unaffiliated/choki) Quit (Ping timeout: 240 seconds)
[6:02] <Psi-Jack> Placement of the wiring was critical too, because if the LED was directly in the path of the S1 switch, it wouldn't work at all as expected, and in the circuit board, it was almost like that.
[6:03] <Psi-Jack> The same thing applies if I move the LED to exactly match though.
[6:03] <brianx> that's the same circuit, just rearranged and with the input tied directly to the square wave and the output directly to ground.
[6:04] <Psi-Jack> Hehe.
[6:05] <Psi-Jack> Almost the same, yes. One notable difference is the short.
[6:05] <brianx> short where?
[6:05] <Psi-Jack> And the fact the LED stays on all the time, except for when you push S1
[6:07] <brianx> the led is on because you set the input voltage to vary between 16v and 32v. there is always enough current flowing to turn it on.
[6:07] <Psi-Jack> I'm adding in labels so I can better explain.
[6:07] <brianx> often, there is so much current flowing that a tiny led would let the magic smoke out.
[6:09] <brianx> watch the led current, it ranges from 8.3ma to 17.7ma.
[6:09] <Psi-Jack> There we go. Updated the gist.

[6:13] <brianx> you have it represented as a ground.
[6:14] <Psi-Jack> Yeah.

[6:17] <brianx> now, your 80hz input is showing 32v peak but your meter showed 16v.
[6:18] <brianx> 8+8 in the two places you have 16+16 will give you a better input value.
[6:18] * Sapio (~SapioSapi@ has joined #raspberrypi
[6:20] <Psi-Jack> Yeah. I just adjusted that, and the ground output resister to 1.6k as well.
[6:20] <brianx> and this "pulse" type input is not able to set a 50% duty cycle.
[6:20] <Psi-Jack> That kept the circuit from fluxuating red.
[6:20] <brianx> but that pulsing of the led is so fast you can't see it.
[6:21] <Psi-Jack> Yeah. And you really can't.
[6:21] <brianx> 80 per second is way too fast to see. 30 per second is about the most we can detect
[6:22] <brianx> the guy who measured this with a scope said it had a 50% duty cycle.
[6:22] <Psi-Jack> Hmmm
[6:22] <brianx> the "pulse" waveform can't have 50%, there is no setting for it.
[6:22] <Psi-Jack> That's measurable with a scope then?
[6:22] * Noldorin (~noldorin@unaffiliated/noldorin) Quit (Quit: My MacBook Pro has gone to sleep. ZZZzzz…)
[6:22] <brianx> but "square" can have 50%.
[6:22] <brianx> yes, a scope can see the duty cycle.
[6:22] <brianx> it better, that's what we're going to be looking at.
[6:23] <Psi-Jack> LOL
[6:23] <brianx> this whole thing is working off the assumption that chris is right in his guesses.
[6:24] * sameee (~sameee@ has joined #raspberrypi
[6:25] <Psi-Jack> Well, that part, yes. :)
[6:25] <Psi-Jack> As per the layout of the circuit, I took well enough good pictures to mimic it. And it's a single-sided board, so really easy.
[6:26] <brianx> yeah. it's the same circuit i drew. just laid out different. i took it from one of the posts you linked.
[6:26] <Psi-Jack> Hehe yeah.
[6:26] <brianx> but i also checked the photos you linked.
[6:27] * Mudary (~Mudary@ has joined #raspberrypi
[6:28] * sphenxes (~sphenxes@81-5-249-116.hdsl.highway.telekom.at) has joined #raspberrypi
[6:29] <Psi-Jack> Hmm guessing on that final resistor isn't an easy one. heh
[6:30] <brianx> it isn't. but the ratio of the input resistor to the output resistor is a safe bet at 1.8 to 1.
[6:30] <brianx> that ratio delivers 3 distinct duty cycles at the output of the comparator.
[6:31] * Noldorin (~noldorin@unaffiliated/noldorin) has joined #raspberrypi
[6:32] <brianx> i updated the ghostbin to have your circuit and my circuit, and a circuit that can be attached to the esp-12 to inject signals that emulate the button board.
[6:32] <brianx> (assuming that chris is right about how it works)
[6:34] <Psi-Jack> Iiinteresting. :)
[6:35] <brianx> simple, right?
[6:35] <brianx> it's less than ideal... the resistor divider depends heavily on the 16V being accurate.
[6:36] <Psi-Jack> Hmmm.. Which I definitely know while the garage door is moving, it's definitely lower than 16V. hmm
[6:36] <brianx> it can be improved by using a zener diode to cap the voltage to 3.2v.
[6:37] <brianx> a 3.3V zener in parallel to the 560 ohm resistor does that job.
[6:38] <brianx> increasing the 560 ohm to 680 ohm makes the signal crisper.
[6:39] <brianx> (but only works if the 3.3v zener is there.)
[6:41] <Psi-Jack> Heh. So, if I'm reading this as-is right, the constant H is the 16V Vin from the line, and the L/H one is the GPIO?
[6:41] <JakeSays> are there any US distributors with pi0w's in stock?
[6:42] <Psi-Jack> JakeSays: Amazon has some, that I saw recently.
[6:42] <JakeSays> cool thanks
[6:42] <brianx> the L/H one is the input from the left wire to the esp.
[6:42] <brianx> the H one is the output from the esp to control the right wire.
[6:43] <brianx> you click on the H one (the right one) to toggle it.
[6:43] <Psi-Jack> Ahh.
[6:43] <brianx> see how it impacts the 3rd graph.
[6:44] <Psi-Jack> So, with that Low, it won't effect it. But High, it'll effect it.
[6:44] <brianx> with it high, it has no impact. with it low, it turns off the output wire.
[6:45] <Psi-Jack> Oh! Yes, I see now.
[6:45] <brianx> so, while the input is low, you turn on the output wire. (it just forwards through the input)
[6:46] <brianx> when the input goes high, you see it with the ESP
[6:46] <brianx> you start a counter and after the right amount of time, you turn off the output wire.
[6:46] <brianx> the right amount of time for S1 is 1/160th of a second.
[6:47] <brianx> the right time for S2 is 1/1000th of a second.
[6:48] <Psi-Jack> Ohhhh.. I see, I see. Interesting.
[6:49] <brianx> the right time for S3 is 1/250th of a second.
[6:49] <brianx> (exact values to be confirmed with your scope.)
[6:50] <brianx> i suspect there is a huge amount of variation allowed.
[6:50] <Psi-Jack> Yes. I see.. The ESP input wire doesn't actually connect to the 16V input, itself, it continues and kinda joins the 16V after the 2.2k resistor. hmm.
[6:51] <brianx> yes. those resistors and the zener are there to protect the esp's input pins.
[6:51] * YeahRight (morgoth@5249A7B3.cm-4-2c.dynamic.ziggo.nl) Quit (Ping timeout: 260 seconds)
[6:52] <brianx> the exact values may vary depending on what the scope sees as the actual voltage. a multimeter doesn't handle pulsed voltage very well.
[6:52] <Psi-Jack> Right. Hmm, interesting. Very interesting.
[6:52] <brianx> most give a sorta average. a few give an instant in time.
[6:53] <Psi-Jack> Yeah, and I have a Craftsman multimeter that goes into auto mode. heh
[6:53] <brianx> so likely an average-ish one. the averaging isn't very accurate most of the time.

[6:55] <brianx> i can.

[6:58] <Psi-Jack> Alrighty, I'll add the labels for how this works, for my notes. :)
[6:59] <brianx> ideally the input to the esp will be on a pin that has interrupt capability.
[7:00] * vstehle (~vstehle@rqp06-1-88-178-86-202.fbx.proxad.net) has joined #raspberrypi
[7:00] <brianx> then you just set a timer to turn off the pin automagically after a delay (assuming the esp has such capabilities)
[7:03] * Psi-Jack nods.
[7:03] <Psi-Jack> Definitely something to check into. I'm currently using Mongoose OS on my current testing model with the sensors attached.
[7:03] <Psi-Jack> Which uses mJS, and can work with C and C++ as well.
[7:04] <brianx> C is the only way to go for the performance needed to get the timing right.
[7:05] <Psi-Jack> Yeah, that shouldn't be an issue. Heh. The mJS can actually call a C function outright. :)
[7:05] <brianx> my guess is that it needs around 10 accurate pulses in a row to "see" the button being pushed.
[7:06] <brianx> you will probably have to turn off wifi when "pushing" buttons.
[7:06] <brianx> wifi likely interferes with timing.

[7:17] <Psi-Jack> The text doesn't snap to anything, completely freeform. heh
[7:17] <Psi-Jack> And only 1 line at a time.
[7:17] <brianx> when you're pushing a button, as soon as you see the input low, you set the ESPout high.
[7:18] <brianx> when you get the interrupt, you start your timer.
[7:18] <brianx> when the timer expires, you set ESPout low.
[7:18] <Psi-Jack> Aha,.
[7:18] <brianx> hopefully, there is hardware in the esp that can just take the timer and automatically set the ESPout low when it expires.
[7:19] <brianx> if not, use an interrupt on timer expire and set it within the interrupt service routine.
[7:21] <Psi-Jack> Yeah, apparently the ESP8266 could use uint32_system_get_time(void) to provide a relative time count in us to use it to get the expire between two gpio interrupts.

[7:31] <brianx> it's all invisible except the web interface you put on it.
[7:31] <brianx> she doesn't need to know that it wasn't a module you bought from china for $10.
[7:31] <Psi-Jack> And I won't be putting web interfaces on it, no need. It ties in directly with HomeKit. ;)
[7:32] <brianx> ok, so it's a homekit interface. i guess that's not web based. app based??
[7:32] <Psi-Jack> The web interface, actually, would be a websocket connection so I could update it if need-be. :)
[7:32] <brianx> how does your phone talk to it?
[7:32] <brianx> and more importantly, her phone?
[7:33] <Psi-Jack> Nope. It's protocol based. My RPi3 acts as a HomeKit bridge, the Apple TV 4th Gen acts as a Hub for HomeKit accessories.
[7:33] <Psi-Jack> And yes.
[7:33] <Psi-Jack> The phones would utilize iCloud to communicate with the HomeKit hub to interface.
[7:33] <brianx> yuck, apple. but to each their own.
[7:34] <Psi-Jack> I was at work yesterday, and demonstrated the fact I could see the status of my sensors, and trigger actions.
[7:34] <brianx> still, it's invisible except as a thing on the phone and tv.

[10:57] <sbeex> hi there :)
[10:58] <sbeex> I try to use RF24 with my Raspberry pi 3 but I can't find any doc about it... so I suppose GPIO from v2 -> v3 is compatible ?
[11:01] <mfa298> the gpio between pi versions is mostly compatible, there were a few small differences between Pi2 and Pi3
[11:01] * fatalhalt (~fatalhalt@c-73-246-193-29.hsd1.il.comcast.net) has joined #raspberrypi
[11:01] <mfa298> you might need to tell us what RF24 is, how it's connected etc. if you want any more help
[11:02] <brianx> sbeex: the base address changes, so the direct access to gpio has to have that updated to work with the 3b
[11:02] <sbeex> thank you for your answers guys :)
[11:02] <brianx> if your rf24 does direct access, you'll need to fix that. if it doesn't, then you don't.
[11:03] <sbeex> so I try to use : nrf24l01 to communicate with my raspi3 and a arduino nano
[11:05] <sbeex> and I followed mostly this guide : http://www.framboise314.fr/faire-dialoguer-un-raspberry-et-un-arduino-via-nrf24l01/

[11:06] <mfa298> if you're using the standard spi interface (/dev/spi*) then it should just work
[11:06] <brianx> TMRh20 code is badly broken. it may work occasionally but it will not be usable.
[11:06] <mfa298> have you enabled spi in raspi-config
[11:07] <brianx> mfa298: the tutorial explicityly disables the kernel driver because the TMRh20 code bypasses it and does direct hardware access.
[11:07] <sbeex> mfa298: in raspi-config I didnt find anything related to spi..
[11:07] <sbeex> I thought it was for pi1 and 2 only
[11:08] <brianx> sbeex: unless he's updated it, the code was written only for pi b and b+
[11:08] <sbeex> brianx: I don't mind using a lib or another to achieve that I have to say.. I simply want to have something that works :)
[11:08] <brianx> there is a base address that has to be adjusted for pi 3b.
[11:09] * Envil (~envil@x4db3abaf.dyn.telefonica.de) has joined #raspberrypi
[11:09] <sbeex> hmmm okay is there something working for 3 ? without too much job ?
[11:09] <brianx> sbeex: i'm not aware of one that actually does work, but i do know that the TMRh20 code is very unreliable.
[11:09] <sbeex> okay so I may change it for something else
[11:09] <mfa298> that guide looks to be using the hardware driver, it described enabling spi with raspi-config
[11:11] <sbeex> rapi-config doesnt have anything for spi in raspi3
[11:12] <mfa298> also i thought the base address was the same between pi2 and pi3 although in most cases you should use a library for gpio which will handle that for you
[11:12] <sbeex> oh I found it in another menu ok :)
[11:12] <mfa298> sbeex: it should be under advanced options
[11:12] <sbeex> thank you ;)
[11:12] <sbeex> ffff... ok raspberry pi world stayed on 2 or what ?
[11:13] <sbeex> it's like 3 is something for "experienced users"
[11:14] <mfa298> there shouldn't be much difference between the pi2 and pi3 in terms of use. Id say the bigger jump was between pi1 and pi2
[11:16] <sbeex> it is really annoying I have to say... last week I came here telling I had a problem with my rf modules not working on raspberry pi because it requires some analog input -> then someone told me to go with nrf24l01
[11:16] <sbeex> and now.. im again blocked :( haha
[11:17] <brianx> hexdump -s4 -n4 -e '"0x" 4/1 "%02X""\n"" "' /proc/device-tree/soc/ranges
[11:17] <brianx> will give the base address

[13:30] <GenteelBen> If you use wireless, the entire band you're on is one collision domain. It's like the least elegant networking ever. Probably worse than token ring.
[13:31] <HrdwrBoB> and yet you don't need wires
[13:31] <mfa298> but then the Pi1 needed less than an amp so more phone chargers would work, Pi2/Pi3 need more than that meaning the likely hood of a phoen charger working is reduced
[13:32] * teepee (~teepee@unaffiliated/teepee) has joined #raspberrypi
[13:32] <oq> mfa298: but we know the amperage rating of the phone charger here, 2 amps
[13:33] <thepeter> BurtyB, oh ... so I have misread that cm3 is same HW as RPi3 ... it is just same SoC but that basically it - means I can't create something for RPi3 and then flash it into cm3, right?
[13:33] <oq> we have the specs, but the product must be dismissed because its labelled a phone charger? nonsense
[13:33] * hydrogen (~hydrogen@amarok/developer/hydrogen) Quit (Remote host closed the connection)
[13:34] <mfa298> oq: we also know (from various people testing) that a lot of phone chargers cannot maintain 5v when suppling the full current - that often doesn't matter for charging a phoen battery, it does matter for the Pi
[13:35] <oq> mfa298: of course it matters for charging a phone battery, the charger isn't directly powering a lithium cell, it's powering a circuit that expects 5v
[13:35] <polprog> oq: but the charging circuit know how much current it can take to maintaing 5v on the inout

[13:36] <polprog> that's how smartphone battery charging circuit is constructed, to work with the shittiest charger out there
[13:36] <HrdwrBoB> new phone chargers have much more power anyway
[13:36] <HrdwrBoB> my pixel XL can draw more current than a pi3
[13:36] <kerio> to be fair a charger that claims to provide 2A at 5V will likely maintain 5V
[13:37] <viju> How much amps can harmful the rpi?
[13:37] * tmch2 (~tmch@ has joined #raspberrypi
[13:37] <polprog> viju: it's not about the amps
[13:37] <kerio> viju: that's not how current works
[13:37] <oq> HrdwrBoB: pixel xl draws more volts
[13:37] <kerio> viju: more like "how little amps can harm the rpi"
[13:37] <kerio> or the charger
[13:37] <BurtyB> thepeter, it's the same ish. most things are going to work the same but obv. no wifi/bt/ethernet/etc
[13:38] <HrdwrBoB> oq: as well
[13:38] <polprog> oq: how can it draw more volts
[13:39] <polprog> it takes 5V because it's USB powered
[13:39] <oq> polprog: usb type c
[13:39] <polprog> type c so what
[13:39] <oq> they have a 12 volt mode in the spec for quick charging a device
[13:39] <polprog> oh
[13:40] <oq> because a usb port can only deliver so many amps before a port melts the phone manufacturers decided to send more volts
[13:40] <BurtyB> you can have 12v with quickcharge on usb2 if you want it too
[13:40] <oq> yes but thats part of qualcomm's propritary "quickcharge"
[13:41] <ali1234> question you should ask is "how can it draw more amps?"
[13:42] * Gathis (~TheBlack@unaffiliated/gathis) has joined #raspberrypi
[13:44] <polprog> i was just unaware that somebody made that option of having 12v on usbc
[13:45] <brianx> the latest ones go to 20 volts now. but the pi can't trigger the high voltage mode.
[13:46] <HrdwrBoB> polprog: it's in the spec
[13:48] <polprog> putting 12V on the USB power rails of the Pi is not a good idea
[13:48] <BurtyB> heh
[13:49] <HrdwrBoB> obviously it's by negotiation
[13:49] <brianx> viju: many cell phone chargers can't even come close to their rated current. the 3b with raspbian will show a lightning bolt in the upper right occasionally when the power supply is too weak.
[13:49] <polprog> generally the design of raspi's power supply is foolproof, if you use regular usb charger, it will just shut down if the charger hasn't got enough power
[13:49] <polprog> ping viju
[13:50] <polprog> also, it's not advisable to power the pi from GPIO unless you know electronics wel
[13:50] <polprog> well*

[13:52] <viju> brianx I have ssh-ed so I can't see anything. Is there any otherway to know that?
[13:52] <mfa298> viju: power issues might be the PSU, the USB cable or a combination of both
[13:52] <brianx> viju: no.
[13:52] <brianx> viju: you have to have a monitor to see it.
[13:52] <polprog> long crappy cables can cause voltage drop
[13:53] <mfa298> brianx: the power led shoudl be triggered by the same monitoring that tells the gpu core the power is low, so the red led going off and the lightning bolt should appear at the same time

[13:58] <brianx> mfa298: the 3b's red led was steady and bright while the lightning bolt was on and off the screen.

[15:27] <mete> do you run them on battery?

[15:30] <Psi-Jack> And since MQTTS is TLS encrypted, that layer is secured.
[15:31] <Psi-Jack> So far, the only security concern I have thus far is the Homebridge itself. I don't think that part communicates with the HomeKit hub securely as it specifically disables the security requirement.

[15:58] <viju> server running*
[15:58] <Psi-Jack> Nope. I have not run Java on the RPi, and I intend to avoid it.
[15:58] <Psi-Jack> Node.JS, so far, yes.

[16:15] <thepeter> viju, if you have programmed in other language it is mostly finding out syntax - principles are almost everywhere the same
[16:16] <Psi-Jack> Well, sorta. Really just depends on his knowledge and logical understanding. :)
[16:16] <thepeter> true :)
[16:18] <thepeter> mostly if one understands some depth in one language it's mostly matter of libraries to go through in ohter lang
[16:22] <viju> I am kind of intermediate programmer.

[16:33] <Chillum> it is great to have a set of basic components. You can get sets that have 20 x of each value for not too much, then you just buy the parts you use the most
[16:34] <redrabbit> i have a box full of parts (capacitors, diodes, leds, resistors..) im waiting for logic gates, pnp/npn, and microcontrollers

[16:35] * Rickta59 (~Rickta59@ Quit (Ping timeout: 260 seconds)
[16:35] <redrabbit> relays sell in modules, so its easy to hook up to a pi
[16:35] <redrabbit> a couple dupont cables
[16:35] <nacelle> one trick is to get some old 80s electronics and desolder the components from it
[16:35] <nacelle> you get soldering practice and components
[16:35] <nacelle> (but the solder is lead based, so be careful)
[16:35] <redrabbit> i suck at desoldering
[16:35] <nacelle> see? you need my trick
[16:35] <redrabbit> you should always use proper ventilation
[16:36] <nacelle> 100% agree
[16:36] <redrabbit> i use a shower moisture extractor
[16:36] <redrabbit> 25W
[16:36] <nacelle> you only have one set of lungs
[16:36] <redrabbit> sucks up all the thing
[16:36] <redrabbit> if you enter the room with a clean nose while im soldering you wont smell it

[16:45] <Chillum> also, add leaded solder to the joints first. The unleaded stuff they use is terrible
[16:45] <Chillum> by adding leaded solder to the join it becomes much easier to work with
[16:46] <redrabbit> what i do is i dont skimp on the flux if necessary
[16:46] <Chillum> love that 80s instructional video music
[16:46] <Chillum> adding more flux to the solder wick helps
[16:46] * Hix (~hix@80-44-94-12.dynamic.dsl.as9105.com) has joined #raspberrypi
[16:46] <redrabbit> i use .5mm rosin core + extra rosin or paste
[16:47] <redrabbit> the thiner wire melts faster
[16:47] <redrabbit> and i sort of paint the solder to the pins brushing with the soldering wire
[16:48] <redrabbit> drag the hot stuff on the pin
[16:48] <Chillum> the lead free stuff used in factories has a higher melting temperature and tends to melt in degrees vs all at once. Adding a bunch of leaded solder to it suddenly makes it behave better during desoldering
[16:48] <redrabbit> under 2s of iron to board contact
[16:49] <redrabbit> the lessons i linked are exelent
[16:49] <redrabbit> i recommand to anyone interested in it, youll learn something

[18:56] <antisaint> My question is ish more specific... I am looing to see if my pi can tunnel the internet out via serial to a wifi router... While using it like a torbox
[18:57] <thepeter> will there be a problem with raspbian if I'll run raspberry with TFT display on GPIO and then I'll connect standard monitor on HDMI? has anybody tried that before?
[18:57] <antisaint> Tcp/Ip thru serial?
[18:57] <thecha> My questiom;if i reboot an rpi with a proper powersupply is it likely that it will corrupt the sd?
[18:58] <antisaint> thecha, Use the reboot command. dont just pull power
[18:58] <thepeter> antisaint, from time to time you don't really get to choose :)
[18:59] <antisaint> UPS my friend
[18:59] <thecha> antisaint→ I don't like to be pednatic but technically i asked about rebooting not yanking the powerchord
[18:59] <thepeter> :)
[18:59] <thecha> :)
[19:00] <antisaint> thecha, It is verry unlikely to corrupt an sd card if the blocks remaining to be written are written out before power off. The host os should take care of that if traditional means of power on off or reboot are used.
[19:00] <thecha> yeah i have a raspbian/its a debian offshoto running... i am not sure if it does so ona reboot
[19:01] <thecha> i know for a fact that it does so ona regualr shutdown
[19:01] <thecha> it even anounces the time when it will shut down
[19:01] <thecha> but on a reboot i just disapears

[19:01] <antisaint> intended shutdown?
[19:01] <thecha> maybe its the static?
[19:01] <thecha> yes
[19:03] <antisaint> Wouldent worry about intentional shutdowns corrupting anything. Any os of these days should handle the write out upon calling shutdown. Mostly leaving the os in ram and unmounting volumes to stop.
[19:03] <thecha> i see thanks man
[19:04] <thecha> so maybe i corrupted my os itself and not the hardware
[19:04] <thecha> i wrote two new entries into fstab
[19:04] <thecha> maybe that is the the problem
[19:04] <antisaint> A faulty power source imho is the most common cause of corruption with sd's

[19:05] <thecha> if that was the case then taking out the sd and changing the fstab would fix everthing
[19:05] <antisaint> Is it that you have a sd with os and its corrupted?
[19:05] <thecha> really all ineeded to do is some semicolongs
[19:06] <thecha> i thougth the sd was
[19:06] <thecha> but i think maybe this time it is really a softwre probelm and the os is corrupte now
[19:06] <thecha> hang on i will check
[19:06] <thecha> :D thanks
[19:06] <antisaint> Is your os on it? Id run a check disk
[19:06] <thecha> is that a gnu/linux too?
[19:06] <thecha> ok thanks i will do just that

[22:09] <brianx> Psi-Jack: avoid onboard regulators, use a buck dc-dc. less heat.
[22:09] <Psi-Jack> Yeah. hehe
[22:10] <Psi-Jack> I've already added buck dc-dc's to my shopping list. :)
[22:10] <brianx> still, the battery will be 4.x volts, so cc buck from your source then cv buck from there to the esp.
[22:12] <brianx> i really like 1584en based buck boards. really efficient.
[22:12] <brianx> always seem to be cv configuration only.
[22:14] <antisaint> I tend to use a 1117-3 for build on regulation.. Can parallel them for more current needs
[22:15] <antisaint> linier tho so idk if that fits your needs as its waaay less efficient than buck

[22:41] <xtina_> (i tried asking in #raspbian but it hasn't been that productive)
[22:41] <antisaint> Limix, the motor your talking about is basically a motor with everything included. It supports a ridiculous amount of communication protocols like RS-485 and TCP/IP and USB... I guess what Im saying is almost any internet capable device would be able to play with it.. What are you trying to do exactly as relating to a pi>?

[22:44] <Limix> anitsaint, I just need to control the motor, but don’t want to use their gui to drive it. I need a few physical switches and buttons to turn to a specific position. Are any of those protocols you see available through some lib for the RPi?

[22:47] <antisaint> Silly me https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjxpui63ZXTAhVW0GMKHZWqByIQFggcMAA&url=https%3A%2F%2Fwww.raspberrypi.org%2Fforums%2Fviewtopic.php%3Ff%3D44%26t%3D141052&usg=AFQjCNEYHNQG_LSqFiNCadYISndQkdFuFQ
[22:48] <Limix> Ah I see ok, makes sense. Thank you for this antisaint. Will start looking into CAN Bus
[22:49] <xtina_> antisaint: is sudo apt-get clean the command you mean?
[22:50] <antisaint> xtina_, Start with sudo apt-get clean
[22:50] <antisaint> && sudo apt-get update && sudo apt-get upgrade
[22:52] <xtina_> antisaint: hmm, why would that solve this specific problem?
[22:52] <antisaint> xtina_, Finally try to overwrite the damn thing with: sudo dpkg -i --force-overwrite /var/cache/apt/archives/gnome-packagekit-data_3.14.0-1_all.deb
[22:52] <xtina_> (i'm hesitant to do a big update/upgrade because i've heard the latest updates break either my i2s mic or my esp8266 module's wifi, don't remember which)
[22:52] <antisaint> Oh, ya that would make me rething it too
[22:52] * batch (~batch@unaffiliated/batch) has joined #raspberrypi
[22:53] <xtina_> is there a way that doesn't involve the big update/upgrade?
[22:53] <antisaint> sudo dpkg -i --force-overwrite /var/cache/apt/archives/gnome-packagekit-data_3.14.0-1_all.deb
[22:53] * nealshire_ (~Nealshire@unaffiliated/nealshire) Quit (Read error: Connection reset by peer)
[22:54] <xtina_> hmm, i don't see gnome-pac... in my /var/cache/apt/archives
[22:55] <xtina_> just 'lock' and 'partial'
[22:55] <antisaint> Then clean did its job
[22:55] <antisaint> That was the file that you were unable to overwrite correct?
[22:56] <antisaint> :D sorry try that with '/usr/share/icons/hicolor/16x16/mimetypes/application-x-catalog.png'

[22:58] * Rickta59 (~Rickta59@ Quit (Ping timeout: 240 seconds)
[22:58] <antisaint> K so your file is locked, and the package is gnome-package... the fix is to force it with sudo dpkg -i --force-overwrite /var/cache/apt/archives/gnome-packagekit-data_3.14.0-1_all.deb Whats ur output?

[23:04] <antisaint> xtina_, So it looks like the package is now removed. Try your install command now
[23:05] <xtina_> antisaint: i think we are going in circles a bit
[23:05] <xtina_> i haven't actually done anything with any of these commands
[23:05] <xtina_> this is the same state i was in before
[23:05] <xtina_> if i try your commands they return the outputs i just shared, but no install command works
[23:05] <xtina_> with the same output as before
[23:06] <xtina_> http://vpaste.net/RepzR
[23:07] <antisaint> Unable to install because of a overwrite error. But your last message stated the file was not there. If the problem installing anything is still present then remove the conflicting package being pi-package-data 0.2
[23:07] * Rickta59 (~Rickta59@ has joined #raspberrypi
[23:08] <xtina_> antisaint: i tried removing pi-package-data 0.2

[23:16] <xtina_> (thanks for all the patience..)
[23:16] <xtina_> i still get stuff like : Depends: gnome-packagekit-data (>= 3.14.0-1) but it is not going to be installed
[23:17] <xtina_> @_@
[23:19] <antisaint> Could try to install the unmet dependancys or try to force it..

[23:21] <antisaint> force it with 'sudo apt-get -f install autogen' or 'sudo apt-get install guile-2.0-libs libopts25-de' Also side thought, is this after installing a package from a alt repo?
[23:27] <xtina_> antisaint: i was installing a bunch of dependencies for gstreamer (not realizing raspbian already came with gstreamer)
[23:28] <xtina_> i can't install a single package right now, neither of your suggestions work
[23:28] <xtina_> even if i use -f
[23:28] <xtina_> i ALWAYS get
[23:28] <xtina_> gnome-packagekit-session : Depends: gnome-packagekit-data (>= 3.14.0-1) but it is not going to be installed

[23:33] <xtina_> this is such a frustrating state *head in hands*
[23:34] <antisaint> From that idk... could try to blow gnome awqay and reinstall but that could cause more orphans :/ Start from where it broke and take it back step by step so try to remove the last installed package
[23:35] <xtina_> it looks like i better reinstall raspbian from scratch :'(
[23:35] <xtina_> i don't really understand the issue, at the moment
[23:35] <xtina_> i thought that there was a conflicting filename between packges
[23:35] <xtina_> but even though i've uninstalled pi-package-data

[23:37] <antisaint> It seems to me that your package has a orphaned dependancy that has been marked to keep upon uninstall.
[23:37] <antisaint> Trying to install a older? version wont work as its already present
[23:38] <antisaint> broke the build..

[23:53] <antisaint> Ive heard the best ones are from alldata..
[23:55] <xtina_> i guess my not using version control bit me in the ass. i'm not sure how to do version control to backup my entire SD card
[23:55] <xtina_> i'm used to using git to backup a project folder or something
[23:55] <xtina_> do people do the same to backup their entire raspbian SD card with git..?
[23:55] <antisaint> xtina_, Have you tried debian rather than raspian and just tuning it for your needs?
[23:56] <antisaint> I personally just make an img of the sdcard as a backup but there isnt really any version control there
