Here is a real life application that I did that has been flying in small plane cockpits for 20 years... lets see who can figure it out first!
needed: an electronic replacement for a 40 year old "drag cup" instrument.
background: a drag cup is a set of magnets spun by a 3 phase tach generator that drag on an iron disk fighting a return spring.
restriction: the ONLY source of power is a tachgen that puts out from 2Vpk@1Hz to 80Vpk@70Hz and there is no real unit to unit consistency in the voltage so don't be trying that
