Measuring Projectile Velocity

Posted September 12, 2012 by Chris

“So being the EE that I am, this got me to thinking: wouldn’t this be even more fun if we could measure muzzle velocity? It shouldn’t be all that hard; we could just hook up a couple LEDs and photo-detectors, fire through the beams, time it with a microcontroller, and voila! So, that’s precisely what I did, except that I decided to go with a couple cheap laser diodes instead of LEDs.”
