at 9:59 am. Filed under DIY Hacks, Electronic Hacks

Electronic test equipment can be very expensive. Have a look at this professional function generator for example. Nuxie has put together a nice simple function generator built around the XR2206 chip. Have a look at all of the project details here.

“In this guide I will show you how to build your own Function Generator. Including component selection, designing the circuit, breadboarding, PCB layout, homemade PCB manufacture through to the finished product.

First on the to-do list is component selection. I decided I wanted to get a function generator IC so I could get it running as quickly as possible.

The main features I wanted were:

* Sine wave output
* Triangle wave output
* Square wave output
* Good frequency range, at least 10Hz to 100kHz ”

    I am every interesting in your Function Generator.Because I need a Function Generator to test my project, But I need to test saw-tooth wave output,Sine wave output,Triangle wave output,Square wave output.If possible,would you mind send your circuitry and component list to me . My E-MAIL is


    thank you
