This the circuit AC dimmer low voltage For lamp 6V. While this friends may don’t see the advantage of this circuit. But I thinks first step advantage be something get learn the work of Triac. And have tall safety , because of use AC Low Voltage. Which the work is simple be The UJT Q1 [...]

This circuit gives sound handful that modifies interestedly, occurrence sound rate cricket Fixed. By R3 should experience change the value C1,R5 and C2 effective that differently. A loudspeaker that use should is model Piezo Tweeter. The Transistor use get many the number. but that use Q1,Q2 be 2N4891 numbers or the number replaces. For power [...]

When Voltage of , Battery desperately will know get with this circuit. It is Voltage Sensitive Oscillator Circuit. By use pillar equipment be UJT 2N4891 equipment numbers are a little. A friend may like. By this circuit will beep alarm generator. When Vin be valuable lower Vz of D1. For the level Turn- OFF that [...]
