I'm realtive new to Bitcoin and minig but i've got some questions.

Right now im mining on a 7990 and a 5770 but the need a lot of energy and are pretty loud. I read about FPGAs as the new alternative, but i could not find any payable FPGAs for "Starter" everything seems to be >500$ but thats way more than i would like to invest for a my first steps.

Also i read, that FPGA are not standalone but need a host computer to manage them via usb. So i think the best way to save some energy would be a raspberry pi. Has anyone already managed to start a miner supporting FPGA on a Rasperberry pie?

What else can you suggest my for starting mining with FPGAs?

Thank you for your Help and Greetings,

I am still waiting for my raspberry pi as well as for my first fpga mining hardware.
I agree with you about the high investmemt costs, first I waited but then I ate the sour apple and ordered some fpgas from enterpoint.

I am thinking of using a fanless Igel thin client with 1GHz cpu as fpga controller, but it draws about 20W. I have two spare ones to sell btw.
Perhaps the Bifferboard can be used to run the mining software on openwrt. The board has 150MHz x86 CU, USB, NIC, 2mb ram, 8mb flash, and draws just 1W. priced at £35.
Another cheap alternative could be a TP-LINK TL-WR703N 150MBit mini WLAN router or other openwrt-supported hardware.

i'm also looking for some good FPGA's, i wan to start a mining rig..

but FPGA's are still very high in prices

I've tested cgminer with a BitFORCE Single on a Seagate DockStar running ArchLinux.  Seems to handle it just fine, and it draws about 9w.

Most FPGAs are very easy to configure and get hashing. You just need to install a driver along with python, and x6500s work great!

I'd also recommend checking out companies the GLBSE.

Hey Guys,

I think the best is to actually buy an FPGA and learn by doing it. I spend a couple of days to run some calculations and these products seems to be the best regarding Mh/s and low power consumption:

  • X6500 FPGA Miner
  • ModMiner Quad
  • BitForce SHA256 Single

I know micro-controllers from industry automation (you may have heard of Advantech from Taiwan) and as long as these Bitcoin boards contain a Watchdog they should run super stable and be easy to use. Guess today only Spartan 6 chips are useful, so no matter which board you buy the procedure to get it running should be similar. API C++ Code:
