its a great idea but really a waste of a perfectly good two axis tracker.

what i mean is.. the tracking mechanism is the expensive part, spend 4$ and use a uproc.

btw, this circuit has been around for a while, some have had success.. but most have reported that it can't find the sun after moderate cloud cover

Generally, LDR's don't work particularly well in this application.

Also, you really need a timing circuit, so it only wakes up & seeks briefly every 10 - 15 minutes.
You can also pwm the motor signal to limit the speed.

RedRok did one like this, but it used an exotic (unobtainium)  controller chip.

I did one, using generic components. In user diaries a few years back.

Still haven't built the mechanical mount for the panels.
