Project Icarus photos

My Tesla coil, Icarus has been completed for awhile now. However in the rush to get everything finished on time for the Las Vegas Mini-Maker Faire, I didn't take the time to properly document everything. However, I finally got back to the project and uploaded some of the photos I did take while building the coil, as well as include some new ones of the finished Tesla coil.

Here are the details and glamour shots you have been waiting for.



The finished coil stands 50 inches in height.

The base was made out of HDPE which was CNC cut out on our Shop Bot we have at SYN Shop.



The primary coil consists of 10 turns of 3/8 inch copper tubing.





The secondary coil is 4.5" in diameter using 22AWG magnet wire with a 5 to 1 ratio.

This was wound using my CNC Tesla Coil Winder, which I designed and details of which are linked.



The MMC array is a single string of nine Cornell Dubilier, 942C20P15K-F, 0.15 uF, 2000V, Metalized Polypropylene Capacitors, for a total capacitance of 0.0167 uF at 18,000 volts.



The primary spark gap is just a single stationary gap, with a quenching fan.



The top load consists of an 18 inch diameter, 4.5 inch spun aluminum toroid.



This is all powered by a Franceformer, primary 120VAC, secondary 9000 volts, 60ma Neon Sign Transformer (NST).



To protect the delicate neon sign transformer, I'm employing a Terry Filter, which can be selectively tapped to handle up to 15,000 volts.



And to control this in safely, a control box which allows for remote operation of the coil. This features an E-Stop switch, a three position key switch to engage the quenching fan and arm the coil for firing. And a momentary fire button. I make use of neon indicator lights for the fan and coil ready lights. The control box also houses the mains filter. It connects to the coil via an umbilical using a four conductor twist lock plug.

I have a gallery setup with the complete list of pictures here:
