If the photodiodes are properly isolated from eachother, and the system has a battery for early-morning power, won’t the unit already turn back to the east at first light without any extras? Shouldn’t that be easy enough to test with the flashlight?
One could use a garden light that turns on at dark to bring the solar panel back to its east position simple and easy!
WoW Robert you gave me an idea for making remote control blinds once I figure out a few more things the can be solar.
0:36, i have the same longetech speakers in the background, and i also used to have the same power supply in the background at 3:09 until it stopped working

good explanations yarrrrrr…………………
@RobertSmith3 Hi Robert, can you tell me what photo transistors you have used?
Wouldnt it be easier to use a timer instead of photoresistor one of the most predictable things is the sun,,,I’ve heard of these setups pionting back to the east when it gets cloudy ,,,,theres a web site that uses a antenna rotator and a timed remote to activate the rotor to piont to the sun,,,I think this is much simpler and more effective,,,,tellme what you think???
@ColonelKudzu What kind of photo transistors do you use in this circuit?
@ColonelKudzu I suggest visiting the forum thread on this circuit if you are having issues, and it’s likely you’ll find the issue you are having, but if not, simply reply to the thread and someone will hopefully point you in the right direction. Good luck!
Robert, I do not see the BAT54 Diode anywhere on your boards. Where is it locasted? We built our board exactly like your schematic, baut the motor runs only one direction, and it seems the phototransistors have no effect whatsoever. It the Bat54 a necessity? I am subtitutting a zener diode for the moment as the BAT 54 has not come in yet.
BTW, Great Video and clear instructions. James
helo, i love to do this as my final project, would you please help me out….

@DHarrisChillin Almost nothing, it is such a small load that you can use a tiny solar panel to power it. Tracking the sun will result in a total higher efficiency.
I think the solar tracker is a great idea, but how much energy does it require to move the panel because if it’s constantly moving, it will have a constant load.
“Photo Transistors” look more like Photodiodes.
Man that is cool how could you make it move incrementally with the sun? Robert since I watched you make your solar panel I have made a couple. I would love to make one of these so I could always get the most out of my panels.
Probably a timed switch would work better to return it back. Even during time changes, if its within an hour or so, no big deal.
That tracker works great.. Keep up the good work. I’ve learned a lot from your videos. Thanks!
Nice work Robert … I have been working on solar tracking circuits for a few years as a hobby… my site is greenwatts(dot)info … I made a solar sensor using GaP leds that might fit well on your circuit… keep up the good work.
great vid dude
Long time no see. Keep up the good work.
