Subject: [alt-beam] 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,
-TurtleTek
