Brake warning/pads

I used to solder a lot and was a little nervous when I saw the "board
computer" pc board. It has a combination of surface mount and through
hole components. Just be carefull to not overheat things and make sure
those surface mount pieces don't get a chance to shift. I don't know if
they are adhered to the board, but if you holy heat one connection at a
time, the other connection will hold it in place.

BTW, I used a temperature controlled weller iron meant for static
sensitive parts. Make sure your iron is at least grounded.

Good luck!
