I can just see the news papers now......
Police find the body of yet another victim. A police spokesman said
"It
appears that the deceased attempted the foolhardy task of trying to
build a Power Smart Head. It took him about four weeks before he
realised it was an impossible task but by then the drive to finish
it
was to great. He appears to have held out for another week or to until
his brain began to swell after seeing too many variations of the one
circuit and finding too many missing 'un-documented' components. This
eventually lead to his demise when his head finally exploded".....
Please kids.....Dont try this at home....

p://www.egroups.com/cal?list"Jason -"Hie wilf...i finally got it working when i dumped darrel schematic and head
for yours...but for R1 i used a 1M trimpot and for R2 i used a 500k
Trimpot..do u think it is appropriate...cause i think i heard u said that
the value of R1 must be bigger than R2.....but the weird thing is when i put
R1 to the max value..the servo spun to the right when the light i equally
bright and when i cover the LDR on the right it turn very very slowly to the
left.....i have no idea how to figure out the combination between R1 and
R2......and wilf if i am going to use fix resistor instead of trimpots..how
should i change the circuit and what value do u suggest...thanks a loot for
your help to get me out of this prob....=)

>how do i make another motor driver oout of a 74AC240...
hey Jason,
a 240 mtr driver is put together a little different than a 245
motor driver.
the 245 was jus posted by Wilf, or the orthodox way can be found at
Beam-Online.
the 240 mtr drivers config can be found at ....
..hmmm dunno where at the moment.
didn't someone bost a new bicore design schematic using a 240 driver
a few days ago?
