this is not a reef DIY

This is not a reef DIY but I guessed it would be more appreciated here in the DIY group that the lounge. Anyone want to start a build group on this ?

Lots of colleges students have built similiar devices, only problem is his seems to be more accurate. Ours keeps hitting the side wall of teh internal barrel, in turns destroys a ton of the electromagnics. best test was 2000ish FPS ( 10 ft range) calibrated using a 3.000G ball bearing.

Funny you mention this......

The two magnets that destroyed the glass on my nano cube were very strong. When I pried them off the broken glass, I didn't want them to attract while I was holding them, or worse yet, my son find them and play with them, so I just tossed them in the air and let them attract insuring I got to keep all my fingers.

The magnets attracted and actually arc'ed a pretty huge spark. I know the projectile was not magnitized, but prehaps at those speeds, sparks and flame is attained, depending on the material it struck.

Seems like I've seen a magnetic rail gun on futureweapons before.. Want to say it used EMP and was rather accurate up to like 20 miles and almost completly silent..

Isn't there also talk of using rail guns for launching satellites and stuff into orbit. Think a big circular track that can "spool up" for a week to get something to 17,500mph then switch to a ramp.

The one I saw on one of those weapons shows launched 5-8" long metal spikes that decimated tanks because they were hitting in at mach 3 or so.
