/diy/ - Do It Yourself

Also, please let me know if you downloaded the files, since I manually typed in the Dropbox link on my phone.

Also, to replace the timing with an arduino, just get rid of the timing board all together and feed your arduino outputs to pins 1, 2, and 3 on J2 of the switching board. The output straight from the arduino should be enough to trigger the mosfet drivers directly.

Things that I already know I would change about this design:
* I would probably select a different type of connector than the ones in the BOM because those IDC connectors ended up being fairly hard to work with.
* I would still use an aluminum barrel, but I would cut it in to three sections and mount a coil at the end of each section, then couple them together with a plastic fitting like in pic related, this would help reduce eddy currents from slowing down the projectile because the 3 sections would be electrically isolated from each other, and when you turn a coil off the projectile only has a short distance to go before it gets to the next isolated section.
