If you have to ask, you probably wouldn't understand.

@Powerlabs that 100KJ converts into how many J of kinetic energy?
-
@Kizmox Licence is cheap, gun is cheap, ammo is very cheap, Excellent out to 100m, gravity rapes it beyond that, etc.

.22lr is illegal to own without lisence and its not powered by electricity ;)
-
MOAR POWER!
Is this still using compressed air to give the projectile a push at the start?
-
@Kizmox A .22LR will put a hole through 4mm of steel plate, what is your point?
-
@kgbean .22 caliber hollow point pistol round: 1237 fps muzzle velocity;
a similar railgun of similar power: Unknown: "I've been running into this problem since I started the 'Railgun' project: you see, my chronograph is only rated to 5000 feet per second."

People like you make youtube annoying.

My inner geek is tingling. But it seems like a lot of trouble for the equivalent of a $.25 .22 caliber bullet.
Railgun.. more like failgun. You made hole through rotten plywood with 100kJ?
Even my 16kJ electrolytic capacitor powered ETG put 8mm projectile through 4mm steel plate and it wasnt performing that well..

@Kizmox Oh, failgun? How cute! Your mom must be really proud of your "16kJ electrolytic capacitor powered ETG" ;) Good job!

Nice job first of all. But I have a question about he oscciloscope part. I see channel A and B showing ~10 V and ~10kV. How does this correspond to the ~10^6 amps? I don't assume the resistance being so low, or am i wrong?
cheers

@Keys1988 Good question! Channel B is reading a Fluke 80K-40 voltage divider and reads in kV. Channel B is reading the voltage across a massive current shunt from an electric train. That shunt is calibrated (by the manufacturer) to read 0.5 volts for every kiloamp, so 80V = 1.6MA (on the 80kJ shot). There is a picture of the shunt at 0.15 . It is labelled and looks like a busbar.

how long did it take to charge?

@100redeye The charger is constant current and puts out 3000Watts, so a 100kJ charge would take 33 seconds approximately.
