Anyway one of these https://tinyurl.com/2t6txzpd . Then a quad op-amp and a few transistors to provide polarity output (needed for a Anglo keyboard) and an analogue voltage to control amplitude. I can provide more info if desired, but perhaps on a different thread. So this is that different thread. I would like to see how the bent coat hanger and load cell are used - a photo or a sketch would be really nice. And your circuit diagram ... pretty please. 1 Quote Link to comment Share on other sites More sharing options...
