apparently you 'can' overclock the CPU - i dont know how or to what value - i'd definately investigate cooling - as i've seen people say they've over clocked to 800mhz

just googled and found this:

http://www.jeremymorgan.com/tutorials/raspberry-pi/how-to-overclock-raspberry-pi/

1000Mhz and much improved RAM speed? I think thats a win BUT i'd definiatly want a cooler on the chip Wink

how many usb block erupters can the rasberry pi handle?
it has two usb connections, so can I hook up 2 x 10 port hubs to it?

i would assume that the hard limit would be 127 *2 USB devices? depending on whether the the two USB ports are separate controllers...

the 2 ports are from a single bus...

so its a maximum of 127 devices then...

The 700Mhz ARMv6 will become the bottleneck before 127 USB devices I would have thought.

Nice device! Can you add mtgox live prices?

Good idea - added to my list.

Also had an earlier version of the script displaying confirmed+unconfirmed rewards total pulled from the pool.
May add it back in if there's interest …

can't quite tell but have you put a heatsink on the CPU?

Yeah runs at 64.8 even with that! 975 core/475 cache/500 ram at 1.35v.

Gonna reformat it soon and make it into a lil VPN/fileserver and send it off for free colocation, running it as a miner is a bit pointless at 0.48khash/s. Stock speed is normally 0.33khash/s!

That free collocation offer is incredible!

unless yer overclocking, in an open case, with a fan....a cpu heatsink is useless on a pi...

Cool project. Wish I could afford to waste money on block erupters, here's my piminer running scrypt, only several orders of magnitude slower.

Very cool with LCD.  Love this project.

Thanks all - appreciate the feedback.

Assembled LCD kits are not currently available - but I will post here if they become available.
In any case - soldering is fun!  No, really - I quite enjoy it myself  Wink

Where can I buy assembled Adafruit 16x2 LCD display? Thank you.

Cool project, I've added a few raspberry pi's to my collection of toys too.  That LCD is really trick, but the thought of having to solder is a bit off-putting.  It would be really cool if they were sold in a more "complete" state. Also I would love it if adafruit would accept bitcoin payment!

interesting project... all in one.

Another pi miner, my mini rig

is this not a bit expensive now as the FPGA board does around 5-6Mhash for 70 and the USB Asic does 333 for around the same? (based on 0.99 BTC) (GBP prices)
