How to Make a Square Wave Oscillator from an OpAmp
Here's a simple way to build an astable oscillator from just a single OpAmp.In my case it was the LM358.
The frequency range is quite limited but it works quite wella s a substitute for the 555 Timer.
All resistors are 10k and Vcc can be between 5V and 15V or more depending on the IC.
