sounds interesting, could you direct me to some resources? What miner can I run in Raspberry Pi?
the fun begins!
This will tell you what you need to know
https://bitcointalk.org/index.php?topic=220905.0Buy your block erupter from one of group buys, not ebay. I won't recommend one (caveat emptor!), but take a look here
https://bitcointalk.org/index.php?board=76.0You'll have to source your own pi, just go googling for it (but again, not ebay). Farnell are pretty reliable (UK based, but with international branches). There may be a waiting list.
Other things you need ... hdmi TV display, keyboard, mouse, cables, powered USB hub (see notes in link at top, not all are equal), SD memory card, SD card reader (so you can flash it), an internet connection (wired ethernet preferred, else you need a wifi dongle too).
Not looking quite so cheap now is it? You may already have some of this stuff though. Some good info on
http://elinux.org/RPi_HubHmm, maybe this isn't your cup of tea? You're not a banker, but do you do geek?
Have Lots of Fun
