Coil Gun

Home/Coil Gun

Project Description

The Coil Gun has a modular design. Each 3D printed module houses of a capacitor bank, an accelerator coil, an optical trigger and a charging circuit. The modules can be stacked. The modules could probably be improved by adding circuitry for sensing the speed of the incoming projectile, and then use this as a factor when calculating the timing of the next pulse.

You can find more info on the charging circuit and modules on GitHub, but I will not provide a full schematic for this device. It looks (and probably also performs) like a toy, but the energy levels involved are lethal. Each module will dump approximately 670A into the drive coil in 8ms. If you accidentally touch a HV terminal, you won’t just get burnt – blood vessels in your body will most likely explode. A “capacitor mishap” will guarantee a visit to the emergency room – dead or alive.

Kanonstøperiet – del 11 (Done !)

By |May 23rd, 2012|Categories: Coil Gun, Electronics|

Sånn, da var jeg ferdig... Jeg har nå printet 2 moduler, satt dem sammen og testfyrt. Jeg utelukker ikke at jeg kommer til å printe flere, men rikosjettene i kjelleren ved selv relativt lave energinivåer [...]

Kanonstøperiet – del 10 (world domination is imminent)

"You got a rush. It'll pass. Be seated.", Danny (Withnail & I, 1987) Det skal normalt ikke mye til før en middelaldrende geek blir opphisset. Å hale noe ut av det det teoretiske domenet og [...]

Kanonstøperiet – del 9 (Now I can see !)

By |May 10th, 2012|Categories: 3D Printing, Coil Gun, Electronics|

Har du lyst til å bygge din egen batteri- eller spenningsindikator, så kan jeg varmt anbefale LM3914. Dette er en enkel liten IC beregnet for å drive bargraph-displayer enkeltvis eller i kjede. Skjemaet under viser [...]
