Subject: More Photovore problems



>Greetings list,
>
>That same photovore (the photophobic one) is having some other problems
also.
>When I put it under a bright light, it [sometimes] doesn't move and I hear
a
>wierd high-pitched sound. It's hard to describe and it isn't very loud,
it's
>like a small buzzing, sort of. Depending on how much light the solar cell
or
>the photodiodes get (I'm not sure which, I'm having trouble getting any
>constant results from "testing"), the pitch of the sound changes. It also
>seems to make this sound very briefly before it fires. I guess this sound
>might be the 1381's. This might help: the 1381's are the "g", they trigger
at
>about 2.4v.
>
>Another problem: One of the motors almost never fires, unless I have the
pot
>turned almost all the way in the direction.
>
>I'm having a lot of trouble with this photovore, it's the first one that
>hasn't worked well for me. I'm thinking of just scraping it and starting
over
>on it.

>Another question, How do you get your photovores with no frame? This is the
>second one I've tryed no-frame on and the first one is barely holding
>together. Super glue is crap, it isn't very strong and it gets all over
>everything.
>
>One more tid bit of information about this: This photovore uses the
>photopopper circuit and I put touch sensors on it. I just used the circuit
>shem to figure out where to put the switches.
>
>Well, thats about it.
>Thanks,
