How two Ardupilots died in one weekend.Yes I was so proud. I had a perfect working ardupilot. I was going to attach my just arrived Z sensor.Then Murphy law kicked in. When a friend was over I showed him my ardupilot. and the working.The positive power line of the lipo accu was not perfectly isolated and made contact with the back plane of the ardupilot.Yes it fried it. :-( . No swet I have a spare one). Solderd the headers tested the upload all fine. Now I needed to load the new firmware for the failsave. I dit this before and had some trouble but I managed. Now I really made a mistake. I forgot to power the arduino externally with the esc when I burned the hex and fuses and is not responding any more. So my attiny45 is gone now. So I just logged in the sparkfun site to backorder two new Ardupilots. And some xbee's end some other stuff.
