OK.....as you may know...Man or Astro-man has been touring with a portable Tesla-Coil
I will have a link to other Tesla-Coil sites here soon
I will have a better description of the Astro-P1 Model Coil soon
I will include photos and video clips soon too!
Short description of Coco's Coil:
After being introduced to Dale Travous in Seattle by Art Chantry, I found my self in total awe by the tesla-coil...after about a year of reading, and researching the device, I set out to construct one for Man or Astro-man?
The coil I currently run is as follows:
Main power:15kv , 120mah center tapped transformer
Primary Capacitor bank: .01mfd 30kv Maxwell Lab Pulse capacitor times 3 for .03mfd
Spark Gaps: 4 series gaps (tungsten faced slugs in aluminum heat sinks) quenched with air blast
Primary: 6 turns of 3/8" copper with 3/8" spacing in a 30 degree inverted cone
Secondary: 6"dia (acrylic form) about 960 turns of #28 magnet wire
Teminal Capacitor: 24x4" aluminum toroid (ok, ok it's dryer duct!)
Saftey: Saftey gaps on main transformer, caps on line feed, air/iron core filters, and RF line filters too!
Ground: Here's the best part...none! well, almost..the secondary is ground to the flight case ..sorta a counter poise
I am currently seeing over 32" sparks...andd tripping 20amp breakers! Whoohaaawww
Spark output would go up if I had a decent ground...
Future plans include a generator mounted on trailer for isolated power, and the van as counter-poise.
and all the mess below is a capacitor design that I have since scrubbed..but enjoy
What I have here is a plate capacitor design for critique.
This unit is rated (calculated, not tested), at 15,000 volts
it has a rated capacitance of 0.01 uf
The dielectric is 1/8th in. (0.125") poystyrene and are 10"x15"
The plates are 1/16th in. (0.0625") copper and are 9" x 14"
The left corner of every other plate is cut off at 45 degrees.
The right corner of every OTHER plate is also cut...this is to allow every other plate to be connected conductivly to each other with the 1/4" copper rods passing through the lest and right sides....the central rod is non conductive nylon and passes through all plates and dielectrics.
A nut on the ends of these rods holds the core together.
The rods pass through the nuts and into the mounting bosses, to hold the core suspended in mimeral oil.
The housing is 1/4" plastic (maybe acrylic..clearr for viewing), The top is scored by rec. to allow for pressure release in the evnt of failure.
Disregard the change in core pattern in the gif below..this happened on the computer and does not signify a design element.
Please take a moment to look it over, any questions, comments, or suggestions are very welcome....
