A tachometer is a device that displays the speed of a rotating object. The most well-known example is the automotive tachometer, which shows a driver the RPM of the engine — information that is particularly useful when the car has a manual transmission. But there are many other uses for tachometers and this tutorial from […]
A tachometer is a device that counts the revolutions of a rotating object, with the most well-known example being the automotive tachometer that monitors the revolutions per minute (RPMs) of an internal combustion engine. But tachometers are useful, and sometimes a requirement, in many other applications. RPM is a very important datum when working with […]
If you manage to get a small lathe in your home shop, it will likely come with a dial to adjust the speed, but it may not have a tachometer to tell you if it’s actually spinning at your desired setting. Rather than accept this imprecision on his model, hacker Tony Scarpelli designed his own […]
