PiMiner - DIY mining controller/monitor with Raspberry Pi [v1.1]

[LaserHorse]

The PiMiner project was conceived as a way to turn a Raspberry Pi into a bitcoin mining host 'appliance' with integrated LCD.
The project scripts currently display the following info:

    • Hashrate
    • Error %
    • Share data
    • Pool address & user name
    • Network difficulty
    • Mining duration / Uptime
    • Exchange rate via MtGox

Full tutorial available here:
http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner

The tutorial contains information which should be helpful to anyone interested in mining with Raspberry Pi (even w/o an LCD, etc); including links to getting started with Pi, network setup, logging in via ssh, etc

Note: The tutorial example uses Block Erupter USBs, but minor software changes should allow use with any USB miner compatible with cgminer v3.1.1

New in v1.1:
    • Added mining auto-start after boot (see tutorial for setup)
    • Time format changed to dd:hh:mm
    • Abbreviated large share count (ex. 12300 == "12k3")
    • Revised error % calculation: 100 * HW / (diff1shares + HW)
    • Added MtGox last, high, & low price (currency can be changed in PiMinerInfo.py)
    • Removed cgminer data logging (was appending nohup.out)
    • Misc. tutorial revisions/clarifications




Feel free to make suggestions as to what you'd like to see added, or additional details to include in the tutorial.

Also, If you build this project - please share pics of your setup!

Very cool great job!

If you've got room on the bus, why not stick an RGB LED in there for instant status observation. Red for bad, blue for something, green for good, orange for warning (say if one or more asics isn't happy), etc...

Plenty of room on the i2c bus - LED could def be handy.  Alternatively, could just use an LCD with an RGB backlight and change backlight color per status.
(The LCD in the pics above is actually RGB, just set to green)

Sweet.
I´ll try it.

Cool

[hotwired007]

Brilliant project! If only ASICMiner drops the price for their USB hardware ...

havent they just dropped them?

[forum2005]

interesting project... all in one.

Another pi miner, my mini rig

[evilscoop]

being an avid fan of mining with the pi, which I do already, ill keep an eye on this...

Was looking into putting an lcd shield on myself, but was after more graphical display of my cacti graphs...as I graph the cg/bfg miner api outputs
Pi's work well with the fpga's too

[erschiessen]

This is so sweet.

I would like to build two. One for K1's and one for K16's.

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)

[billotronic]

this is UBER sexy!

[Bitcoinorama]

Very cool, love your anonymous Tor Pi project as well!

[MWNinja]

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!

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

[LaserHorse]

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

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...

Very cool with LCD.  Love this project.

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