Imagine you are playing an instrument, a guitar. Sometimes you want a strange sound from a normal. Use these ideas of fuzz box circuits and fader controller. You may change…
lets to see Automatic Op-amp night light circuit using IC-741. It is also very simple. As my feelings It has high sensitivity more than one,high accuracy.
This Diode tester circuit can check the diode the good or bad and also can indicate its polarity. using op-amp 741IC and LED for display. [...]
If you need a dual power supply. But you only have a single supply source. So should build this power supply splitter circuit.
