I got you guys good, thats if you did not notice the oddness of the picture in my "RGTC first light" thread. The "high voltage lab" was staged.

The TC is real, but it's actual size and specs where lied about.

The real specs and pictures:
Secondary:
350~ turns unknown gauge
3.5 cm tall
1 cm diameter
Topload:
3.2 cm diameter by .8 cm high
Primary:
4 turns conical 18 gauge
Tank cap:
4 * 1500v metallized film capacitors in series with 1/2 watt 10 Mohm bleeders. Unknown capacitance (I should of written the value down somewhere before gluing the whole thing together!

)
Rotary:
1.6 cm diameter disk with four electrodes
5 mm diameter pager motor used
Power supply:
7kv air ionizer power supply. 2.4 watts was measured at PS input at full power.
Adhesives used during assembly:
Solder (conductive joints)
Wood glue (wooded joints)
hot glue (non wooded joints)
Pictures:
1 The stage
2 Early prototype
3 Primery & secondary
4 MMC bank with resistors and chokes
5 Rotary front view
6 Rotary back view
7 Rotary module complete
8 MMC in it's new home
9 Everything installed

wow, that is pretty amazing. I love the craftsmanship! Now try making that coil work solid state

Funny you should use a air ioniser supply for it, I just installed a pair of whole house electrostatic air cleaners (to replace the 1 we had pre remodel) and was thinking that board would make a sweet power supply. Too bad they cost over a thousand bux new...

Reminds me of my very first coil, 3cc syringe with about 100 turns of 32awg wire, a 5 turn helical primary, powered by a 20w plasma globe supply rectified with a big string of sf1600 diodes, and going into a micro mmc of 3 strings of 4 series .22nf 5kv ceramic caps, with a spark gap made of 2 wood screws screwed into a piece of 1/2" pvc pipe. About the same spark output. Unfortunately my digicam came afer its creation...

Hehe, good one. You really played "newbie" quite well (especially the thing about the cap, but the secondary dimensions were good too, and the lack of details in the first post).

yes, very good.
I was thinking that the bottle on the first picture was kind of strange, and there was a giant piece of solder laying on the floor. If you had that up on ebay, I bet people would have bid on it.

"Now try making that coil work solid state "

This would be very difficult, since I do not have any SSTC experience. I have three IRFR220A in the I-PAK size case that could be used.

"Hehe, good one. You really played "newbie" quite well (especially the thing about the cap, but the secondary dimensions were good too, and the lack of details in the first post)."

I had a hard time coming up with plausible specs for that spoof.

HAHA that's awesome. Nice work. You shoulda made a follow up pic saying" I think I got it tuned" and then had the whole garage filled with 10' sparks. Well what would appear to be 10' sparks.

very good, you got me with that one too

I never viewed the photo full size either, but I did notice the topload looked a bit odd.

I was a little curious about the pic. It was the bottle on the left that gave it away. Very good job though, I though it was odd but didnâ€™t connect the dots. Cool little coil!
