Looking to buy one and looking for some good recommendations.
 
Harry , I have a Starrett and another one up here .
 
I bought a cheapie digital one from Amazon a few years ago. Uses reflective tape that you stick to the rotating part to measure. It was cheap and it works. The worst I could say about it is that the reflective tape wasn't that sticky. Probably available under various names. I think it was $12 or so. I didn't go with quality because I just needed a general RPM answer but I've used it quite a few times since. Looks like there are other $20 ones that have a better gun shape which I think I would like better for aiming and reading the display. It was this one:

There are free strobe light apps for smart phones that can be used to read rpm or get a stop action view of running equipment. I put one on my Ipod. It takes a little fiddling to get it to sync up but it works good. especially in a darkened room.
Motionics LLC is the app I have.
 
I still use an old mechanical one. Like the idea of a phone app. with a strobe light action. It would be a lot easier to use than having to find a shaft center to run off of.
 
I used an app on my iphone called Strobelight. It worked good for checking the speed of my lathe.

And the modern technology associated with.

I, like that tool hoarder above, have an abundance of Starrett mechanical tachs. Zero to 3k, either direction. I will gift you one, for the cost of shipping.
Probably STILL more expensive than the app for the phone you already own.

You decide:grin:

Yea I retired form IT about 2 years ago and remember (1989?) being one of the first programmers to get internet access at work.

Just sent you a chat concerning you offer which would be so cool to have and requested method of payment.

I bought a cheap one, like the one posted by Reddinr (post#3), from Meter-Depot, it was was less than $20, with 2 extra packs of reflective tape and shipping. It works perfectly, eats 9v batteries like popcorn, but is incredibly accurate, but according to their website, it’s no longer available and the new one, is both an optical and contact, combination style unit and is roughly $60.
