I'm looking to build a frequency meter used to measure golf club shafts. I was thinking I might be able to interface it to a pc, I know pretty much zero about electronics or pc's for that matter, but I figure it can be done.
The method I want to use is to mount a light source and phototransistor pointed at one another. The vibrating shaft passes between the two and interrupts the beam sending a pulse each time to the timing circuitry in the pc, and then the pc converts it to cpms and displays the number, in some program, possibly excel or some existing software that I have.
Here's a link to plans for a do-it-yourself frequency meter, but it does not interface to or use a pc, plans include a readout.

Here's a link from a manufacturer of freq meters who sells the machines and his tech notes;

And here's a link to a page where an engineer did make one to link to a pc by using wave studio software that came with his pc and a microphone
**broken link removed**
I already have a clamping device I built for another machine.
Any golfers on the board? I'd love to work out some barter for some help on this project.
Thanks guys for putting up with me.
I'll check back for replies, also my email is mark681137@aol.com
