Ben Builds: DIY Easy Coilgun | Electronic Projectile Launcher

Today we make a homemade coilgun from parts laying around the shop. Using some capacitors and a switch and some other parts, we create an electromagnetic launcher capable to launching a small sharpened nail ~10ft using just the power of electromagnetism.

Thanks everyone for your support! Just made it to 800 subscribers!

hey ben … can i know how many turns have you given to the coil and thickness of wire 🙂

SniperClan Gaming says:

Nice mate im gonna make a shotgun varient

Salvatore Coppola says:

E comm si brutt

Naz says:

I think you could add an infrared sensor at the end of the coil, this way, when the bullet is detected, the coil is turned off during maximum velocity

Fargutin says:

You could have use some phototransistors to turn of the coil when the projectile hits the middle of the coil

Riding With Dustin says:

The cringe is real
