I put in a new SD card low and behold it worked again. So I got quite excited soldered it up and tested it again and it was still working great.
Thought right nows the time for the battery. Disconnected from the PC I put in the 4x1.2v 1800mAH AA pack and the leds came on for things. Stopped it and went back on the PC connection without battery and now I'm back to
ERROR: Unable to mount SD card : NOT_READYVery perplexing. I can't read/write to it at all now, tried formatting it and reflashing the espruino. PC read and writes fine.
