Here are some random things I have for sale. I am not buying and selling this stuff to rip people off and make lots of dollars. I enjoy making things, and basically this is just extra crap that is collecting dust around my apartment.
High Voltage flyback kits
Kit comes with used flyback transformer (pin diagram for basic HV circuit included) and (1) KSE13009 NPN transistor with heatsink and two resistors. Use for spud gun ignition systems, capacitor chargers or other HV applications. These are all the parts (except batteries)you need to get a nice hot plasma arc. All you gotta do is solder the four parts up with wires. Should certainly be able to get it working the day you get it (takes me about 5 min). $12 each, plus $4 to ship.
Coil Gun Kits
If you want to try your luck with a small single stage coil gun without doing much part scrounging, this is for you. You get a 300V charging circuit (from a disposable flash camera) including a ~100 uF 300V capacitor, a spool of magnet wire for winding coils (~100 ft), clear plastic pipette tube for a barrel and a small neodynium-boron magnet for a projectile (while they last). For added power or those of you who are considering a multi-stage design, I'll throw in 3 140uF 450V caps and mounts for an extra $5. Kits are $10 plus $4 shipping, an extra 5 bucks for optional capacitors. You can see the step by step instructions here.
Custom Built Jobs
If you want me to build it for you, we can do that too. Cannon mount sparker, handswitch controlled sparker or for the lab, just shoot me an email. Here are some photos of a remote control job (used for remotely detonating spud guns) I sold for $65 plus $7 shipping.
Electrolytic UPE Capacitor Bank
Here are 7 UPE 100VDC 3300uF capacitors mounted on a rail in parallel. Would make a medium coil gun with 115 Joules of energy. $12 bucks plus about $7 to ship.
