Somewhere I have read an article on building an electronic rev counter for the lathe, but the brain cell being what it is, temperamental at best, refuses to remember where.
Having "googled" (new fangled verb) I am still no wiser.
Any brain cells out there with the required knowledge to pass on?

"Our own" Tony Jeffree wrote an article in MEW a while ago and the details and a copy of the article can be found on Tony's pages here:

The bits, I believe are available at the Model Engineers Digital Workshop here:

Many thanks ....... I can retire the brain cell.
Interesting. Anyone tried one? Could be handy for calibrating a fixed tachometer if they're accurate enough

Bought one of these. £1.99 and £8 postage (China is a long way and it did come quickly)
Seems fine. The "390 rpm" speed on my lathe registered 416 rpm by laser. It does however need the reflective strip to read properly. A quick test with Tippex didn't work.
It can't replace the Tony/Lester "Revmaster" but for the sort of speed checking that I need it's a cheap and flexible option.
