solar tracker homemade

This is my simple solar tracker, all you need is a charger 6 volt,timer for 1 minute, turning the system is simple and effective and proven to work,every 1 hour for 1minute solar tracker is moved by 30 degrees, was divided into 9 positions in 1 minute, to turn i use a DC motor with gearbox, it was too fast so I added my gear that I made from old gear to reduce the rotation speed for another 3 times so that the speed of turning panels is just right,after sunset i return panels back to the starting position,p
