How to make a homemade tachometer

For those of you who don't know, a tachometer is a tool or device used to measure the revolutions of an object in RPM (revolutions per minute). It seems to be of no use, but for example, it can be used to measure the speed in the construction process of our wind turbine.

Making a tachometer

Tachometers usually cost around 40€, but this one, which also has the option to buy, costs 29€ with shipping included. Of course, as it is a DIY project, they send it to you disassembled and you have the time to assemble it ;). For all those who don't like the idea of buying it, on their website they have also placed the plans and circuits so you can make it yourself from scratch.

If you don't like this model, I found a couple more for you, one of them here and the other here.

Seen in Make.
