2.2 MHz light bulb plasma globe

Looks like that will get VERY HOT!

[MaryStewart]

cool!  you made comets! :D

[nillchen]

very nice; is this a one-stage-rf-oscillator that feeds the primary coil and what's the power? Thanks!

[jmartis2]

@nillchen yes this was a single-switch oscillator, somewhat untuned (probably operating between class C and E), about the power I don't know but might have been around 100-150W.

nice flame-like arcs. high MHz, too. Great TC

Great! I noticed the same effect but only in certain brand of light bulbs, specially the Philips (the old ones). I´m using a small tube powered coil in the Mhz range too, at lower frequencies the yellow shine it´s not that visible.

I love the little coil made with the photo tube! Have you the schematic of the driver or a reference? Thanks!

[m3sca1]

nice coil - what else can it do ?

[codemsan]

wow thats really trippy, high freq. give a nice flame effect!

[OnnomonnomonnO]

ake je vystupne napatie?? ..typujem nad 15 000V

[jmartis2]

tak to netusim :) na takove vysoke frekvenci to se stejnym napetim dela vetsi "efekty" nez s mensi frekv., takze to asi tolik zase nebude :)

[holycrapapie]

Wierd, doesn't lightbulbs usually shine purlple-y pink?

[jmartis2]

yes they do, but only at "flyback" frequencies (tens of khz). With such a high frequency like here, the discharges are different, almost flame like.

hold your finger long enough and it'll burn through the glass -.-

trust me it hurts like h$ll
