Well if it was working before you addded the larger cap across the power
pins, then remove that cap. The funny high pitches buzzing noise is normal
and to be expected. There are ways to compensate for this, but one of them
is not placing a huge cap on the power lines.

>Ok, I've replaced the photodiodes with photoresistors and grounded them,
like I was told. Well I was happy when the head started to move...and toward
the light, too! Well, it also made a funny high pitched buzzing noise. So I
added a larger cap across the power pins of the IC and it didn't change.
Anyway, after about 30 seconds, it stopped working all together! I have to
trn it off and then on again before it will work. It reminds me of a
microcore going in to it's saturated state after a few cycles. Can anyone
help me??
