DIY Simple Signal Generator
« on: February 18, 2009, 09:15:38 PM »
People keep asking me about simple signal generators.
I once purchased a signal generator and it was quite expensive.
The signal was dirty as in it was never stable on frequency.

Then i decided to build one myself, for less then 10 Euro and it was remarkably stable.
So i decided never to buy one again.  :)

Marco.

This is a very nice download - I've been looking for a good function generator schematic.  It's simple as well.

Would anyone here know how to modify the tone generated from (I believe it's about 1KHz) to something like 500 Hz? Or, would anyone know of another simple tone generator kit?

Thanks in advance.
