im working on a dyno project for measuring HP of 1/5 scale rc engine(23 through 31cc, about 3 to 5 HP).
found this handy computer program that uses audio input signal to read RPM. you put a magnet somewhere on a rotating part and put a coil next to the magnet (you can even just use an earbud as the coil).

already tested the HP of one of my homemade air powered engines. it put out 70 milihorsepower!
now that i have tested the software i am ready to start building the real dyno.
i think i will start with an engine dyno because its easy. them make a chassis dyno maybe.
