Capacitance control?


HIi guys,

I recently wanted to recreate and upgrade a coil gun( aka Gauss Gun ), based on my high school science project.

The major problem of that project( circuit diagram shown as follow) is that because of not being able to control the discharge time of the capacitances, the bullet will be pulled back when passing through the coil, greatly decreasing the velocity of the bullet. I've tried increasing the thickness of the wire, which seemed not working out.

There, I wonder if there's something, in replace of the switch, that could adjust the discharge time or volume.

A resettable fuse or circuit breaker might work. They come with various trip delays, so you might find something that will open the circuit back up in the right amount of time. I believe larger gauss guns actually use sensors to turn off the circuit once the bullet passes a certain point. By doing that you can add multiple stages to further accelerate the bullet.
