new photo's of my tesla coil
Original poster: "Shaun Epp by way of Terry Fritz <twftesla-at-qwest-dot-net>" <scepp-at-mts-dot-net>
I finally have some good pictures of my tesla coil running. They are
outdoor photo's. They are a little fuzzy, I used an 35 mm automatic camera
without a tripod, oops. Anyway the streamers are peaking around 4 feet, I'm
not sure how to measure the length accuratley, but Im sure someone on this
list could tell me. 8 - ))
To see them go to http://hot-streamer-dot-com/temp/
and look at the files named :
"shaun tc1 photo high.jpg"
"shaun tc2 photo.jpg"
"shaun tc3 photo.jpg"
"shaun tc4 photo.jpg"
Tell me what you think?
More are to come of the setup and also shots with a tripod, better film, and
a better camera.
below are the specs of my coil:
12Kv, 60mA Neon sign transformer for the power source.
RC filter with safety spark gaps.
2 gap static spark gap with tungsten rods
Primary coil has 11 turns of 1/4" copper tubing, total outside diameter is
17 inches. Tune seems to work around
the 10th turn.
Tank capacitor is 0.0215uF at 28Kv, from the Geek Group
The secondary is 22 1/2 inches x 4.25 inches wound with 26 gauge magnet
12" x 3" spun aluminum toroid, I know --- it's a little small!
To make these photos, I used a 3 x 4 foot chicken wire & aluminum foil
ground plane underneath the tesla coil and I over coupled the coil, just
before problems arrose. I used the house electrical ground ;-)
