Question gentlemen; I have been a tuning cars again and would like to measure rpms more precisely than via a jumping needle on a 50 yr old gauge, is there some sort of electrikery powered gadget available that one can point at a flywheel/pulley/fan/shaft that will accurately measure the rpms?

I dont do Amazon, I shall peruse eBay and distribute at least a tiny amount of funds to a fellow countryman.
