I need help figuring out what I did to my handyboard. I had it all
assembled, tested, and working when one of the battery leads touched one of
the solder spots on the board. A small puff of smoke rose from the board
but I was able to disconnect the battery quickly. The board functions fine
except for the following things;
-Motor drivers 0 and 2 don't work at all.
-The board works with power from the telephone cable but won't even turn on
using the battery alone. Memory is restored when the battery is connected.
I think the inductor was where the smoke came from because it has a dark
brown color to it and I can't get a continuity reading through it. I was
thinking about replacing the inductor to see if that was the problem but I
can't find a place to buy just the one part. If anyone has any ideas on
what to do or if someone has an inductor that they could spare I would love
to hear from you. Thanks.
