Coil Gun [Part 3] – Testing the Boost Converter

I thought I would post a quick test I made of the boost converter circuit. In the video below, I’m charging the capacitor to a voltage of 200V. The charging takes about three seconds to go from the 15.8V (the initial voltage of the battery) to 200V, which is right within the ballpark of the simulations! … More Coil Gun [Part 3] – Testing the Boost Converter

Coil Gun [Part 2] – Theory, Design and Simulation of the Charging Circuit

WARNING: This circuit can produces voltages that can cause serious electrical burns or easily kill you if not handled properly. Please do some research before beginning this project to ensure you are taking all proper safety precautions when working with high voltage. If you are at a beginner level, I strongly encourage you to start with … More Coil Gun [Part 2] – Theory, Design and Simulation of the Charging Circuit

Coil Gun [Part 1] – Theory and Proof of Concept

I would venture a guess that 95% of all electrical engineers find their way into the field by trying to build a coil gun as a kid. In some way, it speaks to every boy’s innate desire to put their life in danger. The definite possibilities for electrocution and spontaneous fire have resulted in dozens of Instructables … More Coil Gun [Part 1] – Theory and Proof of Concept
