Subject: [alt-beam] ARGGGGHH!!!!
Walkers are neat, right? well the do their little thing and its cute and all
that jive and suddenly you get to think wow, if i can do this i sure as hell
can make it track light right? So i'm bored last week and i put a photodiode
and .5M resistor in a series parralel to the timing resistors right, light
subtracts resistance by lettin in that .5M resistor. SO WHY THE HELL IS IT
ONLY PHOTOPHOBIC! i've spent the last week tryin to get this thing to act
phototrophic and all i can get n.i.m.b.u.s. (Nicely Intergrated Machine But
Utterly Stupid) to do is cower away in shame! I've put these photodiodes and
leads in every which way but all he does is either go away from light or only
turn one direction! i checked the diodes, they work, the resistor are 1%
tolerance and i'm about to freak out about this little problem but as long as
it works Photophobic i think i can live with it, but I was wondering if
anybody had a decent answer to my incoherent bablings of impatience (its a
virtue, or somethin like that). I've manage to at least get the diodes workin
correct, if you put them in different ways it does funky stuff!

those damn little eccentrics on the pager motors. I had one helluvatime
gettin those off, sometimes they use a type of epoxy to hold the buggers on
em! GOOD LUCK!

photodiodes around.

tried it, for some reason he just doesn't like it when i do that! its kinda
wierd, when i change it, it only turns one way even when i flip the diode,
however if i put them back to the same old anti-phototrophism it works! wierd

Make it photophobic, then physically grab the photodiodes and move them so
that they point in the opposite direction, while their leads are still
attached to where they were before.
Good luck!
