The Coolest MV Speedometer

We normally find the speedometer on the vehicles, as it’s one of the most important devices that measure the speed of a vehicle simultaneously. The speedometer was invented by the Croatian Josip Belusic in 1888. In the beginning, it’s known as “velocimeter” rather than speedometer. It started being used in the early 1900s and became standard equipment for every vehicle by 1910 onwards.

Speedometer is not being used in the land vehicles, but also in boats (pit log) and aircrafts (airspeed indicator) too.

Many of the modern speedometers are in digital/electronic form. A rotation sensor that usually mounted on the rear of the transmission is for delivering a series of electronic pulses to the rotational speed of the driveshaft. The computer is uses to convert the pulses to a speed and displays the speed on an electronically-controlled digital display.

MV Speedometer

Today’s project is very special, as it’s a MV speedometer that specially designed for coilgun projectiles. In this case, you’ll need to determine the speed of coilgun projectiles while experimenting usually counted the frames of high speed camera and filming the projectile in the same time.

So, if you’ve the interested to calculate the velocity and kinetic energy of the projectile, then this MV speedometer is the excellent choice for you!
