My girlfriend want her lamp switch, but from bed! So I must planned a clap switch. The circuit is very easy: I don't used a microcontroller. The input is a microphone, what the audio signal accept. ...
This Is one of the best power supply, It mixed the original labor supply desing in one new projekt
In this project we designed a compact, two layer printed circuit board for our new, vacuum tube based power amplifier design. The quality of the finished PCBs was excellent!
Good quality PCB with fast delivery!
It's secret.
