incredible invention

[@dr2man]

Great circuit, I built one it works great for a small application. Can you tell me or direct me to another video that provides for an upscaled version? For example, I ould like to use this with a 12 volt dc motor to move my large solar panel. Will the d2822 ic work in a 12v application or would you recommend a differnt IC?

[@ElectroRetro]

D2822 can't handle higher load

@Ronald Tuman There’s a good book called junk bots, bug bots and bots on wheels by Dave Hrynkiw and Mark Tilden which is about building BEAM bots. Bots totally based on logic chips no PLC, or any microcontrollers, and there was a solar tracker you’re asking about, in large 12 volt scale. I can’t recall the maker’s name but if you can track that down they may still have notes and circuit diagrams, to this day. I remember it was quite a good size sun tracker totally based on these circuits, basically right up your alley. You can also look up Wilf Ritger he seemed to have done a lot to.

[@virajkavinda8812]

Can you explain the working principle of this system and how accurate this system

[@ElectroRetro]

It is a Dual Audio Amplifier IC, meaning it has two Op-Amps inside its package. This circuit uses two ldr. it's pins connected to inverting and non inverting inputs of this ic. when the intensity of light falling on a LDR increases, its resistance decreases. The output polarity of the ic will change according to ldr conductivity. So motor turns left or right

[@Electronzap]

Very cool circuit.

[@alexanderwingeskog758]

Amazing stuff! The ultimate challenge though would be a 2 axis solar tracker with a single motor. Pull that off (with the least amount of parts, energy and the cheapest) would almost be a Nobel prize :-) a small 5 watt solarcell getting almost 5 watts for 12h :-)

[@PositronX]

Just make the circuit twice: one for each axis.
