I like to present my "High Voltage ignited Plasma Bulb"
Step 1: The material
A Neon filled bulb (any type will do but I found out these fireballs are best)
Electronics from a disposal camera (how to modify see here: CLICK)
A potentiometer 200K
A handle for the poti (I used a foot contact of a bulb)
Some fittings made of copper and brass
A base plate made of wood
Step 2: Preparing the parts and mounting procedure
First I cut a round piece of wood and an other piece in same size from vulcan fibre.
I clued this together and mounted the potentiometer on his round plate.
As a knob to turn the poti I used a E27 bulb fitting. Inside the E27 I clued an E14 bulb fitting that fits exactly to the axis of the potentiometer.
On the last picture you can see the first mounting of the parts.
Step 3: Cabling and finish
The cabling is very easy:
You can see the battery case and the low voltage cabling running from the case to the switch and then to the electronics and back.
The high voltage cabling is easy as well. From the electronics to the middle contact ot the potentiometer than from one of the other potentiometer contacts the middle contact of the bulb. The other wire of the high voltage output runs to the big brass stand under-need the bulb.
If you switch the power on turn the potentiometer you will see this.
Last I mounted some brass screws around the poti knob and mounted the switch into the wooden stand.
Step 4: Finished
Lets have a look what´s happening if you touch the bulb.
So lets switch the lights off and play around....
