I've been working on & off on this little project, as a part of my test equipment, its a set of generators, a 1 hz at 1 pps, a fast edge pulse generator at 2.64/5 kHz, and a signal generator from 1 hz to 100khz, all very useful and in the one box. next project already started, variable signal generator , sweep generator, and a ramp generator. then the wobulator gets my full attention, planned for next year concentrating on my favourite part of the hobby , servicing, fault finding & repairing. See Martin useful things to build , you have more experience than me.
