So... The next semester has began, and so has the new year.
Quentin set up a vastly more accurate method of measuring the projectile speed using his camera equipment. Pictures and data to come, but for now here's what I did most recently.
I had a disposable camera on hand and wanted to do something with the flash charging circuit. Since these have been used as pranks to shock people, I thought, "Why tether your shocking power to a door knob? Why not make it portable?" So I did just that.
As a sidenote: electricity is dangerous, don't try this stuff unless you know what you're doing.
