Hello, an idea passed my head right now... If I take the +5V and +12V (and GROUND, of course) from the PC power suply and use it to feed the PIC in-line programmer board (David Tait's SERPIC), can I cause any harm to the programmer, target board ou the PC? This would save me a 12V power suply and make the things a bit more ellegant (only 3 wires from the programmer to the PIC). Thanks, Brusque
