Power Battery Saver Circuit
This is power battery saver circuit using IC-555 timer. The lamp is controlled with PWM model by adjusting of potentiometer P1. PNP power transistor to driver lamp. When use normal lamp,some times a lamp that is used have too bright. To adjust the brightness with the variable resistor, it would …
3000 watts Dimmer for  Inductor Load
This is the 3,000 watts Dimmer for inductor load example: the Electric Fan, AC motor,Electric drill etc. But most general dimmers is used for resistors load only such as lamp, soldering iron, heating coil,etc. Why our project can do? The normal dimmer cannot use for inductor load, because the phase …
Modify AC Dimmer to automatic light switch controller
Way to modify an AC dimmer into a light switch circuit, to turn ON-OFF and automatic light dimmer or two in one form. Since, the general dimmer uses a triac to control a load like a relay contact. So we can easily make it by a few parts. The automatic …
Dimmer circuit
The AC light dimmer circuit can control light bulb or speed AC motor, we use triac and SCR as main,and adjust potentiometer and switch,more circuits
