Interested on mining on this $20 computer that only draws 250mA, runs OpenWrt. It has ETHERNET, WIFI, USB, UART, 20+ GPIOs but size is only one square inch...? ;D ;D ;D

It would never produce more bitcoin than it would cost to run.  And, it has less computing power than a RasPi from what I can tell, which is also not viable as a miner.  Sorry...

The day's of CPU mining really are behind us.  Some will continue to do it.... but in most cases it does not bring a profit and does not even pay electricity.    Low powered computers are great for controllers ... but miners themself not so much.

One I still want to test out as a controller for other lotto is RPI zero.  I'm still holding out till I find it for the 5 dollars it should be, I refuse to pay extra.     It is amazing how long it has kept selling for higher then what it's normal price should be.  But I think a RPI zero could be interesting for running a compac or two.

this thing with "Dock" basically has the same hardware as a tl-wr703n, and you can get them for $10 to $30, same Mips24K CPU, 4MB storage, 32MB ram, USB, 100M ethernet With 802.11 b/g/n. also it does about 500KH/s on bitcoin.

Scratch that! Get a GL-AR150 http://www.ebay.com/itm/321850131925 $27 + $5 shipping heres some info: https://wiki.openwrt.org/toh/gl-inet/gl-ar150

CPU mining in this level is not profitable... if you have free electricity you probably won't get your hardware cost back in some years
