Circuit Project Electronic

This circuit is DC Dimmer Circuit. By use IC LM555 be model Astable Multi vibrator. It is can change translate Duty Cycle with fining VR1 and VR2 be formed fine brightness level that want. The output of IC1 be formed limit load in something Oscillator and limit [...]

I like mini power amplifier less 100W because it is low cost nad easy to make project.(View Circuit)
The 65W Amplifier Class AB,I use main part electronics are IC LF351 and thansisror two part TIP3055 and TIP2955.
The LF351 is a low cost high speed JFET input operational amplifier.
The TIP3055 and TIP2955 are small size but have [...]

If you require more than 1 amp, the 7805 can be combined with other components to provide an output of up to 3 amps, with the circuit below. The current is switched through the TIP2955, so the 7805 can be run without a heatsink since it only regulates the voltage. Note the 3-amp diodes in [...]
