Hi,
Yesterday, on my X10, one of the blue LEDs went out, but the miner still hashes at the correct speed. I restarted, reset the pi and controller, and tried different SD card with no effect. Today, I spent a few hours online, looking for a reason/solution, but couldn't find any. When I went back to the miner, I found another blue LED has gone out (still hashing correctly). What could be causing this?
I've seen this on quite a few of the X10's I've been working with. As long as the cards still occasionally get the flashing green LED (I believe 3 flashes/second when a share is found) it should still be mining. I've yet to find one that wasn't working fine when the blue LED was off or intermittent.
Definitely keep us up to date if you find otherwise.
