Two Short Videos: 2) RPM

This is the second of today's two short (too short?) videos.

Here's an affiliated link to the App if you're interested: https://apple.co/2Od1qWl

Update - Re-edited to change the term "phone accelerometer" to "phone sensors" and replace a repeated phrase about the registered app with a mention of the additional speed measurement options available in the registered app.

I'm glad it was handy. I really like publicising these cheap little things - but for some reason it seems to upset a lot of viewers in the short term - but over time these kind of videos are the most popular.

That RPM app is brilliant, I'd never have guessed it would exist, thanks for posting about it. FWIW, my $30 Amazon USB record player is only 1% off at 33-1/3, better than I would have expected... I suppose it might come down more to the supply used.

While I was watching, you started talking about an app and I immediately thought "how clever, use the phone's camera to watch the disc rotate and calculate speed based on the frame rate".. Might be a wiser approach for those slick 78s ;-)
