A function generator I made from an ICL8030 chip I've had laying around for a very long time. If you want a schematic, sorry I don't have one, so try google! Plenty of them there. :)

  • Nice design! Are you stepping the finished wave forms through the reed relays with the decade counter? Do you know of any other way to do that without using a mechanical switch? I have made those electronic toggle switches before but only to power separate circuits using transistors. I don't think that would be possible in this case. Those relays are expensive. Seven of them would almost double the cost of my function generator.
