I have some aircraft instruments I'd like to be able to use, a couple are ww2 and I'd lik to keep them original, I dont mind bypassing the internal circuit but I dont want to go to the stage of fitting a servo.
I have used the lm1819 to drive air core instruments, in fact I had a couple of boards from old guages with them on, however I'm finding ti difficult to get them now for less than silly money.
Is there a replacement to this ic, or does anyone know of a schem for a simplish circuit to generate the sine and cosine signals.
Maybe I should write some code to do it.
