Finished Audio SIGGEN

I have boxed up the Audio SIGGEN. This provides an output of up to +10dBV, 3.2V rms and can drive a low impedance load. The frequency range is from 10Hz up to 100kHz in steps of 10, 100, 1KHz and 10kHz. It operates from a 12V supply.

Inside the box are an Arduino UNO, an AD9833 digital frequency synthesiser with analog output (scanned ROM) and an LM386 audio amplifier.
