Homemade Optical Tachometer

[mikefr24]

I finally made a website for this project if anyone has an interest.

It's a homemade optical tachometer that works really well. I originally posted the project on the www.helifreak.com website and had several guys successfully make it. I designed it for Helicopters but it could be adapted to work on other stuff.

Thanks,
Mike
