When i was using operational amplifiers at school lab i wanted a function generator at home to play with and work on circuits with Op Amps for better understanding. So i found on the internet a free function generator circuit which uses the IC XR-2206, i printed the PCB with my UV exposure box, i bought an enclosure box, i put everything inside and here is the result. The function generator can generate Square, TTL, Sine and Triangle waveforms from 1Hz to 1Mhz with Voltage regulation to Square Sine and Triangle waveforms.
