How to begin FPGA mining Since I own two FPGA:s I want to get started mining. It doesn't matter which currency I am mining, only that it works. I would prefer to do mining of Bitcoin, Ether, Dash or LItecoin but anything that works with my FPGA will do. 

My FPGAs are Altera DE2 and Altera DE2-115. I already checked out one project that was too old (it used the getwork call which has been deprecated. 

Any suggestions what I should do? I know C programming and some electronics and VHDL so I can find my way around a complicated installation or building it.
I'm a total newbie but so far the problem appears to be solvable. This is what I did with my Altera DE2-115 hooked-up to a Windows 7 machine:


got fpgaminer's open source FPGA bitcoin miner on Github
got mining proxy on bitcoin.cz
set up an account with slushpool.com (had to use VPN because my ISP apparently blocks connections to slushpool over http :((( )
registered an online BTC wallet with blockchain.info
updated config.tcl to connect to localhost:8332 port and reflect my slushpool-related credentials
downloaded miner's bitstream into DE2-115
launched mining proxy
and finally ran mine.bat

The hashrate was indeed around 50 Mh/sec but after ~10 seconds the Cyclon IV chip got rather hot, so I decided to play it safe and stopped mining. As the next step I'm planning to install an active cooling system to continue experiments such as switching from my Windows rig to Raspi, mining altcoins, etc.
