DIY dual power supply & function generator! Explained!



Published
Hi curious ones out there!

In this video I'll be showing and explaining:
- how to build a straight-forward dual power supply: For input it uses a simple supply, such as a single battery. It offers 3 output pins: HIGH, LOW and
MIDPOINT (aka positive, negative and 0)
- how to build a signal generator, using the ICL8038 chip + some external components for selecting frequency, duty cycle, etc.
- how to amplify the signal and optionally apply an offset to it and then present it to the output as a "usable" low impedance signal

Dig in!
