Subject: [alt-beam] PSH weirdness


Hie all...i hope u guys could help me fix this problem in my version of a
PSH...it uses LDR and the circuit and 0.1uF cap from wilf tutorial and a 1M
pot for R1...it worked flawlessly ....but after i put in the R2 which is a
500K pot...the head can hardly move....i stacked two AC240 to provide enough
juice for the gearmotor....and i wired the pin 1,2,4,6,8 temporarily to
ground....so can anyone tell me why is it like that? and how do i make it
track my hand....

All this basically boils down to is if you make a bunch of $$$ off someone
ells idea ... he can come after you ...BUT it has to be for enough real
dollars for him to pay his attorney about $4,000 to start and a share of the
spoils later... so unless you are making a really good living off it don't
worry about it!
don't get me wrong, I'm all for giving credit were credit is due but I have
seen some real thieves get away with it...

WOULD YOU LIKE SPINACH WITH THAT?
Spinach may be good for more than a healthy diet. Researchers at Oak
Ridge National Laboratory (ORNL) are using proteins extracted from the
leafy green vegetable as the basis for a new kind of electronic chip.
They say the spinach biochip may end up in the next generation of video
imaging equipment, ultra-fast switches and solar power generators. Eli
Greenbaum and his ORNL team have found a way to line up the spinach
proteins on a flat gold surface. In the presence of light, the proteins
generate about one volt of current - in principle faster than a
conventional silicon photodiode, says Greenbaum.
