This past weekend was a very intersting weekend; I went to the TCBOR
Teslathon on Saturday at Richard Hull's house and got to see all sorts
of fun things! There was a little bit of everything to see and play with,
including ultra-high flux Nd-Fe-B magnets, a demonstratation of
gasseous lighting using electrodeless neon and argon tubes driven
by a solid state Tesla coil (from Duane Bylund), a small (about 6" high),
completely silent, disruptive discharge Tesla coil using a quenched
gap, a 25 Watt argon laser, a coil/amplifier setup that could detect
magnetic field disturbances generated by waving a magnet over 20
FEET away from the coil, and most impressive, Richard's 9000 watt
magnifier coil throwing off 10' sparks!
I was quite impressed, and more than a little excited...I really want a
magnifier (and all the other neat stuff too)! The day after I got home, I
went down and fired up my conventional 600 Watt Tesla coil and
almost cried when I saw the puny 8" streamers coming off the toroid
with the secondary arcing merrily away. It seems like it's time to really
get down and make the time for experimenting; the heck with my family,
I'm gonna be a high voltage scientist (just don't tell my wife and kids!).
Seriously though, I have been inspired to try to put more time into
experimentation. I just hope it works out as well in practice as it does
Their salvage yard also sounds like a dream come true. I learned that
the two 8kV, 10 kW transformers that Richard is using to power his
magnifier cost him just $5 each!!!!! I've been looking all over Baltimore
for an industrial salvage yard, but I haven't been able to find a single
one after 3 days of searching and calling around. I am going to have to
make a pilgrimage to the RIchmond yard just to see what it's like (it's a
shame it's four hours away, 8 hours of driving makes a long day but I'd
do it in a heartbeat).
At the Teslathon, I bought Richard's "Guide to the Colorado Spring
Notes" for $20 and a 35kV, 3kW potential transformer for $35. That's
the most exciting $55 I've spent in a long time! The transformer weighs
230 lb (grunt!), and I was assured that I could run it at 10 kW without it
even breaking into a sweat. I had to ask my neighbor to help me get it
off my truck when I got home, and he seemed interested (fearful?) in
finding out what I was doing with something you don't normally see
without an attached telephone pole. Since I'm still working on limiting
my current so I don't melt my breakers, I can't do anything with it yet.
Hopefully I will be able to fire it up as a Jacob's ladder sometime soon
just to see what it can do, and eventually I'll build a coil that can use it.
I'll keep you posted, but Ciao for niao.
