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 epxosure box, i bought an enclosure box, i put everyhting 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.
