My (Derek Woodroffe) SSTC2

My SSTC2 with a 1Kw Lamp Plasma globe

Me, Waiting for sparks from my OLTCII

Hay It Still Works.

And Continues to work..


Mark Hales Brought the last of his cubes of sodium. An placed then one by one into a bucket of water.

The Sodium was coated in oil and so took a while for the water to get into contact.

Contact !!

Another Peice, never got a really good contact with the water 

The last peice was squashed to give a better surface area.

Mike Harrison looking deeply into his new
Spark-O-phone.


Mike's Jacobs ladder-O-phone


Ans Mike's small Spark-O-phone.
(The pan pipes of death?)

Paul Benham brought his Big coil

And displayed some large streamers

Philip Strauss brought his excelent 20" bonetti machine.

Which gave 15+cm sparks

Steve Connor arrives with his DRSSTC in tow.


The DRSSTC survived the train trip wrapped in Steve's Sleaping Bag.
(Steve denys sleeping with it)


And it proceded to give excelent displays of sparks.

that were huge for its small size.

With no problems at all.

Steves DRSSTC with a spinner on top


Which It failed to move one inch.
Where as My OLTC drove it quite well.
See, DRSSTC's can't do Everything as well as OLTC's

Streamers avoiding  a sphere

More Arcs to the spheres.

And even more...

The Coilers and Visitors

And thanks to the
Cambridge museum of technology
for hosting the event.

I started the day badly. My secondary earth wire touched the inside of my secondary. 1/4 hour with emery paper and a sanding wheel, the coil was back working.


Ready for Demos.



My AD-OLTC entertaining the crowd with a rendition of Twinkle Twinkle. (Mental note, must change the tune!!)



A demonstration of My CW Multiplier with a bowl of "womble shit"

Click for a movie with tin pie dishes


I blew an IGBT whilst power arcing to earth, One more defenceles transistor gives it life to the cause.


A member of the public (sorry I didn't get your name), brought his (rather nicely built) ignition coil for faulting.



Martin tries to determine why the output is poor.

Bob Takes a break..



Paul and Dave, sorry if you haven't brought a coil, you get you picture taken instead.


Bob's Coil , being set up.

Bob, Looking for arcing in his capacitor bank

Bob, Still looking for arcing in his capacitor bank



Must be arcing in here somewhere.


Bobs Control Desk,


Bobs transformer and charging inductors.


Bobs rotary, (high spin speed, with economy wash cycle)



Bob at the controls, tuning.



About 4' sparks from a "wizards hat" on top of Bob's coil.



My OLTC2



Working, About 2.5-3' arcs to air, sparks to ground still blowing OV trip though.



Mike Harrisons Bipolar Marx, Suffering from damp and sawdust, but still giving 3' arcs.

 

Mike Harrisons cap bank "Interfaces"
with a motherboard.

 

And again..

 



The "Jacobs laddder-o-phone of death"

 

Mike descovers a new way of cooking apples. A steel whire through the center and hook it up to the cap bank. Tastes rather metalic though..
