Coilgun – v.0.2

So, I finally got around to pushing out this update…

We have a second iteration of our coilgun, which was mostly put together and worked by my friend Clinton. For quick specs, we used thicker wire (21 gauge), more wraps over less area/layers (who-knows-how-many-layers over maybe 2 inches on a maybe .2 inch pipe versus one layer over 6 inches of an about 3/4 inch pipe), and more voltage ( 2 dual-parallel caps in series). With these combined, we upped our speed from around 2m/s to around 18m/s. We also switched our ‘ammo’ from rare-earth magnets to plain old screws with their heads sliced off. No pics on this iteration, but we do have video of Clint shooting a defenseless binder.

We’ve been working on a multi-stage iteration; more details soon.
