DIY Bullet Speed Meter for Coil Guns

at 4:45 pm. Filed under Complex Hacks, DIY Hacks, Electronic Hacks

Megavolts.nl built a speed meter that can monitor the speed of his coil gun bullets. The bullet trips an entry beam and an exit beam which are at a known distance apart, this allows the speed of the bullet to be calculated and displayed. The build is detailed and includes code and schematics. Here is a Google English translation. Big thanks to the creator for translating the project to English!
