The Electromagnetic Projectile Launcher

My name is

Huy Tran

and I'm a passionate engineer that wanted to develop a coil gun (Inspired from videogames non the less). This is a blog to track my progress, enjoy.

i finally got it to shoot! at the cost of an IGBT. proof of concept that it works. i loaded the projectile ~1/4 or 1/6th of the way into the coil.. charged the caps to ONLY 100V triggered the IGBT, and out goes the projectile hitting the box what it looks like to be almost perfectly square on. the box actually had two layers of really good cardboard so it didn’t puncture the box completely… and it knocked the box over and the projectile bounced back to the wall.. the coolest part: SILENCE leaving the barrel… on firing.. you just can barely see it exit.. and the next thing you know.. a pop (when the projectile hit the box) and the box tumbling over in front of you… pretty cool @ only 100V.. i’m gonna pick up a relay from jesse tomorrow to see if that will suit my needs as a trigger… we’ll see. (for the second stage though i think i would still need and SCR/IGBT as a relay wouldn’t trigger fast enough)

the coolest part: SILENCE leaving the barrel… on firing.. you just can barely see it exit.. and the next thing you know.. a pop (when the projectile hit the box) and the box tumbling over in front of you…

pretty cool @ only 100V..
