I have just completed a new project, a hand held analog synthesizer utility box called the Synth Testbox. It has a precision VCO volt/octave calibration voltage source, a patch cord tester, and a bargraph type voltmeter that can display CV, gate/trig and audio signals. A very handy little device!

Lots of info here including schematic:

Take care,
Doug
