Subject: [alt-beam] Photo-phobic photovore...
Greeting List,
I've recently finished yet another photovore. It uses the "photopopper
circuit" and has touch switches. This is the first one of mine that hasn't
worked (except that photopopper that I mucked up on the soldering). At first
it wouldn't work very well at all, only one motor would fire, the 1381 (I
think) would buz and it would just sit there. After some tinkering I got it to
work. However, there is one problem... It's photophobic. Instead of going
towards light, it goes away from light. Why's that? I've checked the schem and
everything looks right. The only thing I think could be wrong is the
photodiodes, I might''ve put them in wrong, but I can't tell.
