Cool! Welcome to the forums! How long have you been mining for?
Thanks, I did BTC a couple of years ago, LTC around Februaryish, only recently switched from reaper to cgminer and using kattare.
Someone asked me about making hardware to sign transactions on a device, and since i already had a few boards built with usb/cpu and oled display i knocked something up, always looking for more interesting things to add to our conference badges.
