Jason sent in his latest creation, it’s a 1.25kJ Coilgun. Check out the cool video of it below, you will get a good overview of how it works and see it in action. I like the fact that he is re-using some parts in the build like the cell phone charger for some of the low voltage circuit needs. By the looks of the damage caused by the gun I am thinking that this might be the most powerful one we have seen yet. I like the dial that allows the max charge voltage to be dialed in so that the system can’t overcharge. Pulling the trigger disconnects the charge circuit and triggers the SCR which dumps the capacitor energy into the coil.
