Coil Gun Progress

Follow along with the development and updates of this project.

Fried some circuits

Accidentally put too much voltage through my circuit and fried many components... Led me to learning abt inductance tho, so still call it a win :)

Fried some circuits

Started bench testing

Lots of testing. Bigger coils, bigger projectile, new circuits.

Started bench testing

Simulated performance of coils

Wrote python program to simulate current and field strength in a coil based on relevant parameters. Physics is great!

Simulated performance of coils

Design utility circuits

Designed and tested circuits for control and measurement of important values (capacitor voltage, projectile position/speed etc.)

Design utility circuits

Added second coil

Double coils, double speed? Need a way to measure velocity, but seems to be working :)

Added second coil

Redesign PCB

Redesigned PCB to fire with capacitors. Also simplified MOSFET driver and removed need for microcontroller

Redesign PCB

First PCB design

Designed the first PSB for manufacturing. My first time designing a PCB ever :)

First PCB design

Semi automatic tests

First tests using triggers to start and stop current

Semi automatic tests

Prototype PCBS

Designed an soldered prototype PCBs to control current to the coil

Prototype PCBS

Tested Hall-Effect sensors

Will be using these to automatically manage current in the coil based on location of the projectile

Tested Hall-Effect sensors

First test

Wound coil and tested a launcher using a single coil

First test

Created coil holder

Designed and printed the first version of the coil holder

Created coil holder
