Prototyping the circuit for a phototropic robot built from the parts of an old mouse

That little black chip in the middle is the simple brain

Starting to solder up the circuit for real

Battery taped in and relay glued in

Soldering the "crap I bumped into something, let me back up" part of the circuit

Backup switch glued and soldered in

Goood, goood

Eyestalks etc wired up, all done

I call him Feivel

Feivel meets Herpe, the curious-yet-skittish-puppybot

Herpe is kind of an idiot so his circuitry probably won't progress past the breadboarding stage
