Spark Gap Tesla Coil 1.0

Conceived during a summer that probably could've gone to better use (Junction, whyyyyyyy did I attend you???), SGTC 1.0 was what first got me into the whole business of shooting lightning.

Long exposure is best exposure.
Design Considerations:

Modularity
- At some point, I want this thing to shoot monster streamers, so being able to swap components would be nice.

Reliability
- Demos are far more fun when things work.

Sexiness
-Hnngggghhhh *ahem*

Construction breakdown:

Chassis
-Two sheets of HDPE held up by threaded rod columns
- Fan bolted onto a piece of plexi that was subsequently ziptied onto the threaded rod (farming hard)

Secondary
- Donated by the Daniel Kramnik
- 4" diameter, 2.5'~ tall
- 24 AWG???
- Resonant frequency ~555kHz
- Added toilet flange for increased mounting stability to chassis

Primary
- 1/4" copper refrigeration tubing wound spiral-style
- Added supports for sexiness

Topload
-  Some very sad aluminum ducting wrapped in even sadder aluminum tape. Not exactly my best handiwork.

MMC
- Scavenged Panasonic metal film caps
- Rated for ~8kV 
-Capacitance: ??? (something in the 0.005uF range)

NST
- 9kV, 30mA (problem, MMC?)

Spark Gap
- Zinc-plated hardware (a bad idea)
- Cooled via muffin fan (a yummy idea)

Here, have some pictures media!


Note: bleed resistors help
 prevent accidental electrocution
Protip: when laying the primary,
 go from the center outward 






mmmm, HDPE

Results:
14"~ streamers
