[15:31] <shodan45> 'scuse my ignorance, but in the shiny new pics I see what I believe is ram or flash (hynix chip) where the cpu is supposed to be - is the cpu underneath that?
[15:32] <ahven> yep, PoP technology
[15:32] <ahven> gpu, to be exact
[15:33] <shodan45> freaky :)
[15:33] <shodan45> wait, gpu? not cpu/SoC?
[15:36] <ahven> err, yeah, my bad :9
[15:37] <ahven> memory on top, SoC underneath
[15:38] * jluisn (~quassel@ has joined #raspberrypi
[15:40] <IT_Sean> it's a sexy silicon sandwich
[15:41] <ReggieUK> should be DoS
[15:41] <ReggieUK> ductaped on silicon
[15:42] <IT_Sean> ahh ducttape. Is there anything it cannot do?
[15:43] <IT_Sean> Isn't ducttape mildly conductive?
[15:43] <IT_Sean> i think that might pose a small issue for the board.
[15:44] <IT_Sean> trust me... Bad things happen when you drop conductive items on a live circuit board.
[15:44] <IT_Sean> baaaaaaad thiiiiings.
[15:44] <Skummel> done it often IT_Sean?
[15:45] <Thorn_> even worse than ducttape, is that cheap silicon-glue they use in amplifiers etc
[15:45] <Thorn_> after 2-3 yrs, it turns darkbrown, and excretes a very conductive goo/liquid
[15:46] <Skummel> oh well, worse case blow a fuse and destroy a $25/$35 board
[15:46] <IT_Sean> That's not good.
[15:47] <Skummel> nope, would have to buy a new one..
[15:47] <IT_Sean> yes, and that'd be another $35 + shipping + time spent stalking the mailman.
[15:48] <Thorn_> yes
[15:48] <Thorn_> i wish Royal Mail would stop STEALING PACKAGES round here
[15:48] <IT_Sean> And my mail carrier doesn't speak english, so, he's no fun to bother with "Is my package here yet!?"
[15:49] <ahven> "when package here?" :P
[15:50] <IT_Sean> he doesn't speak engrish either.
[15:51] <ahven> ok, "package?"
[15:51] <IT_Sean> pretty sure
[15:51] <ahven> or just plain "where box?"
[15:51] <IT_Sean> pretty sure "package?" is english

[15:53] <IT_Sean> so... when do we think the raspi 'll be loosed upon the earth? Early january? middle january?
[15:53] <Thorn_> middle i guess

[15:57] * chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) has joined #raspberrypi
[16:11] <IT_Sean> I was rather hoping for early Jan.
[16:11] <IT_Sean> :p
[16:11] <IT_Sean> Hell, i was hoping it'd come put earlier this month.
[16:11] <IT_Sean> *out
[16:11] <ReggieUK> I've got my money on august
[16:12] <IT_Sean> ReggieUK: you, sir, are a pretzel.
[16:12] <ReggieUK> cynical? who me..... :D
[16:12] <UnderSampled1> IT_Sean: I'd guess, take the length of time it took for the beta boards to be printed and populated, then add that to the date when they tell their manufacturers to start production
[16:14] <IT_Sean> Good point. Full production is usually slightly faster, once the prototypes are vetted, in my experiance, though. So, late-early Jan is not unlikely.
[16:24] * gabriel9 is now known as gabriel9|work
[16:42] * shodan45 glares at raspberrypi.org's db server
[16:48] <shodan45> so it looks like it'll need 3.5W max power? 5V*0.700A ?
[16:48] * shodan45 goes solar panel shopping
[16:53] <ReggieUK> http://www.bbc.co.uk/news/technology-16316439
[16:54] <ReggieUK> that's very encouraging
[16:58] * gabriel9|work (~quassel@ Quit (Read error: Connection reset by peer)
[17:00] <shodan45> so, one of my ideas is to make a "money tree" device with a raspberry pi in the "trunk" and solar panel(s) as the leaves, which would run a bitcoin miner (or similar) to generate "money"
[17:00] <shodan45> for "free"
[17:00] <shodan45> yeah, it's not practical, but it's fun :)
[17:04] <UnderSampled1> shodan45: the raspberry pi would make a terrible bitcoin miner
[17:05] <IT_Sean> !w
[17:05] <PiBot> IT_Sean: in Boonton, NJ on Fri Dec 23 19:25:00 2011. Temp 46??F. Condition: Mostly Cloudy, Humidity: 71%. Later 45??F - 25??F. Condition: Mostly Sunny

[17:05] <Dagger3> I wonder how fast the GPU would be though? probably still uselessly slow, but it would be very low power consumption
[17:06] <UnderSampled1> I doubt it's a very good gpgpu
[17:06] <UnderSampled1> but I don't know
[17:06] <shodan45> UnderSampled1: I know, that's why I said it's not practical
[17:07] <Dagger3> well of course you don't, since it's all proprietry and secret specs :/
[17:07] <UnderSampled1> maybe if you had the raspberry pies as the leaves :P
[17:07] <Dagger3> but hey, it's not like anybody might like to do anything with the GPU, is it?
[17:07] <UnderSampled1> and power it from the ground (roots)

[20:32] <UnderSampled> WASDx: wassup?
[20:32] * ReggieUK (ReggieUK@5ac9ad1f.bb.sky.com) has joined #raspberrypi
[20:33] <WASDx> I got a DC motor. It works fine of a 1.5V AAA battery
[20:33] <WASDx> does that mean the GPIO can power it? if it's 3.3V
[20:33] <Thorn_> probably not enough current
[20:34] <WASDx> current = ampare?
[20:34] <Thorn_> right
[20:34] <UnderSampled> yes, current is amps
[20:34] <Thorn_> what voltage is the dc motor supposed to run at?
[20:34] <UnderSampled> I don't know
[20:35] <WASDx> dont really know. It worked fine with 4 batteries, 6V
[20:35] <UnderSampled> you have to look that up in the datasheet for that specific motor
[20:35] <WASDx> i took it from an old CD player
[20:35] <Thorn_> if it works on 6V
[20:35] <WASDx> it says D/V 5.9 ROHS
[20:35] <Thorn_> tap from the 5v gpio pin
[20:35] <Thorn_> then it's just a matter of how much power you provide on the usb input
[20:35] <WASDx> I will use an 1A power source for my RPi
[20:36] <UnderSampled> Thorn_: what 5v gpio pin?
[20:36] <UnderSampled> WASDx: doesn't the raspberry pi only have 3v3?
[20:36] <WASDx> you told me so, i think
[20:36] <UnderSampled> or, sorry, that was also for Thorn_
[20:36] <Thorn_> there's 5V available before it gets to the r'pi's power section of the board
[20:36] <WASDx> my motor works with 1.5V anyways
[20:37] <Thorn_> on a copperstrip/pin that will allow you to take as much current as you need
[20:37] <Thorn_> whereas the 3v3 gpio pins are meant for signalling, not power
[20:37] <Thorn_> (afaik)
[20:37] <WASDx> if i connect a resistor between my motor and the battery, does the battery lasts longer?
[20:37] <UnderSampled> but you just said 5v gpio pin
[20:38] <Thorn_> i didnt mean to say gpio
[20:38] <UnderSampled> ah
[20:38] <Thorn_> i'd provide a link to where Gert said this, but the raspberry pi forums are being retarded
[20:39] <UnderSampled> anyway
[20:40] <Thorn_> Top Left is 5V0
[20:41] <UnderSampled> the microusb supplies 5v
[20:41] <Thorn_> yes, but you can supply or take power from the Top Left pin
[20:41] <UnderSampled> ok
[20:41] <Thorn_> (if you supply there though, you must regulate it first)
[20:42] <UnderSampled> huh? isn't it already regulated by the microusb charger?
[20:42] <Thorn_> you are thinking of this wrong
[20:42] <Thorn_> i think you're seeing it like this
[20:43] <Thorn_> USB -> Power section of board -> Rest of board (including 5V0 pin)
[20:43] <Thorn_> it's
[20:43] <Thorn_> USB _OR_ that 5V pin -> Power section...
[20:43] <Thorn_> i could have read this wrong myself, but that would be odd
[20:43] <UnderSampled> there is no OR in simple circuits
[20:43] <Thorn_> i'm still looking for the post where Gert explains this clearly
[20:43] <UnderSampled> only AND, right?
[20:44] <UnderSampled> so if there is power on the USB, you can take it from the 5v pin
[20:44] <Thorn_> yes
[20:44] <Thorn_> AND is more appropriate
[20:44] <UnderSampled> or, you could choose to power the raspberry from the 5v pin (as long as you regulate it)
[20:44] <Thorn_> right
[20:44] <UnderSampled> but if you are taking power from the 5v pin, powered by the usb, then it's already regulated
[20:44] <Thorn_> yes, i never said otherwise
[20:45] <UnderSampled> oh, I just read it wrong
[20:45] <UnderSampled> sorry
[20:45] <Thorn_> the 5v0 pin is pretty useful though
[20:45] <WASDx> does a resistor reduce power consuption?
[20:46] * kcj (~casey@unaffiliated/kcj1993) Quit (Ping timeout: 240 seconds)
[20:47] <Thorn_> p=iv
[20:47] <Thorn_> you lower v
[20:47] <Thorn_> :P
[20:47] <WASDx> we learn U=RI and P=UI at school
[20:47] <WASDx> i think i could have calculated that myself then
[20:49] <Thorn_> did the website get slashdotted again? it's ridiculously slow
[20:49] <UnderSampled> well, the pictures of the populated boards probably hit some important sites
[20:49] <UnderSampled> like that bbc article
[20:50] <WASDx> they're stealing our bandwidth!

[23:05] <Jarii> :)
[23:06] <indystorm> Yeah, :) I've been looking for something like this for YEARS- and I knew it would only be a matter of time when the price came down enough- and the micro usb power...!!! GENIOUS!!! If it works right, it will be WONDERFUL!!! :)
[23:06] <ChrisLenz> welcome!
[23:07] <Urokhtor> Yeah I'm totally looking towards powering my sex toys with this beast.
[23:07] <Jarii> :D
[23:07] <indystorm> lolol
[23:08] <indystorm> OK, well I'm looking to power it via battery and Solar panel.... but to each their own!!! lol
[23:10] <WASDx> I'm looking to power it by itselt by connecting the USB power to its USB-port
[23:10] <WASDx> infinite power
[23:10] <UnderSampled> Yess!
[23:10] <UnderSampled> but you might have to rewrite physics first
[23:10] <UnderSampled> :P
[23:11] <WASDx> right
[23:11] <WASDx> Didn't take that into account
[23:11] <Urokhtor> I'll just make tiny Chinese people spin a dynamo.
[23:15] <UnderSampled> I suggest using a waterfall
[23:16] <Urokhtor> I'm pretty sure that the Chinese are still cheaper.
[23:16] <UnderSampled> nature works wonders at magically vaporizing water at the bottom and transporting it to the top
