Nothing burnt

My Yellow Drum Machine (perhaps I sould find another name? .. Anyways, it is using small motors instead of servos.

So motors are constantly fired to hit a drumstick - end then the motor returns to it´s original position via a spring mounted on it.

All the sudden nothing worked, and so I thought I had bunrt something, as the motors constantly send current back when the spring returns them. .(And we are talking thousands of stick-movements)

But.. all is cool :D It was a stupid battery clip that had a bad soldering inside. hahaa.. I am a happy man. Thought I would be forced to do all sorts of reverse-current protection now, but no, still never killed a picaxe or a axe020 board!

And BTW; I am even using the inputs as outputs ("high portc 1", "low portc 3" etc) - and they have no darlington or nothing.. drumsticks feeded current straight from the picaxe chip! (And back as a "shortcut" when the stick returns to default) That´s pretty raw IMHO, but nothing burnt :)
