Circuit Project Electronic

Today I receives electricity old printer from a friend. I think it can’t is usable , but power supply circuit still can be usable , modify be power supply source in electronics all work. I then build to is DC Power Supply 9 Volt Regulator, that can give current [...]

This circuit designs for modify power supply input 12V from battery or the other. Have the level voltage be down be left 9V be stable or , 9V at 2 Amp DC power supply . By this circuit gives usual equipment , seek easy. Be [...]

This circuit is DC to DC converter model step down voltage. That can modify voltage input 12V DC from be DC 6V , 7.5V and 9V by have the size current about 1A - 2 Amp think. Be easy circuit use Zener diode maintain one’s position voltage. Be stable [...]
