hello everybody :)The way of building electronic bagpipes is explained in details in this video. Starting from SR latch through the concept of a stable multi-vibrator oscillator, the used circuit is build in details and the function of each part is it is discussed.see you next time view more

This is a prototype on a Variable Frequeny Driver or VFD. With this circuit we would control the frequency of high AC voltage and by that the speed of induction AC motors. Since we work with high voltage, is a dangerous circuit so be careful. The idea is to turn 230V AC voltage to DC vo... view more
