What is the scientific principle behind using s plasma globe to light up a matchstick?

Why does a matchstick light up when one places a coin on a plasma globe, uses a paper clip to hover around the coin while holding the matchstick alongside the paper clip? (note the video does not use a matchstick, but it still applies the same concept)

can a plasma globe that requires 12 volts and 500 mAmps be put to 12 volts and 12 Amps?

I have a project idea and need this information before starting.

How to make a Plasma Globe from a lightbulb without rewinding the flyback? Answered

Hi, I noticed that on here: https://www.instructables.com/id/Make-a-Plasma-Globe-out-of-a-Light-Bulb/, You have to rewind the flyback. How could this be accomplished without doing that? Thanks!

Plasma ball with Giant vodka Bottle?

Hi I am thinking of using a Giant 3 litre Smirnoff vodka bottle  as shown in the link below: http://www.licorea.com/smirnoff-3-litros-dosificador-p-809.html?language= To make a Plasma globe but inside the bottle. I need some sort of high voltage supply and an electrode but aren't sure what else . The main Problem I can see is creating a vacuum inside the bottle . as I don't have a vacuum pump. Does anyone have any tips on how to create a vacuum inside the bottle? Also would an inert gas work instead. Any help appreciated  Thanks Ben

High voltage lamp driver

I have a high voltage lamp driver that i took out of an old projector, I want to know if i wil be able to make a jacobs ladder or plasma globe with it? It supplies 25kv or 12.5kv on each of the two wires? it was used to power the lamp of the projector and it connected directly with the lamp wires. PLEASE HELP!

How difficult is it to Increase the intensity of a plasma ball?

I just bought a cheap USB (5v) plasma ball. Quite frankly, the intensity of the streams is pathetic. You can barely see it when the lights are on. I wanted to use it for a decorative project, but need to increase the intensity of the streams. Would increasing the voltage (say from 5v to 12v) work? Or is it more complicated than that? I can do basic electronics, but mostly just simple stuff following circuit diagrams etc.

Is a transformer that puts out 12VAC at 2.4 amps safe to use with a circuit that only draws 0.58amps? Answered

The circuit i attempting to drive is one from a plasma globe. I was not sure if the excess output of the transformer would "fry" components on the board

Stun Gun Mod Suggestions/Tips? HV Power!

The 2 images are the type of stun gun parts I have, I believe its a spark gap igniter one but m not 100% on that as I would rather leave it in the cardboard circular case unless I get confirmation it could be modified. What kinds of projects could this be used for, I'm pretty sure its DC powered and attempted putting the outputs to curved metal electrodes for a Jacobs ladder but arc stays in one spot after many adjustments.  Ive only worked with HVAC with an unrectified flyback for plasma globes. Anyone have any suggestions on what to pump this badboy into. P.S. Using 2 metal screws from an Xbox 360 and putting them very close together makes a very nice whistle to it, :).

BJT vs MOSFET? Answered

-- background: In my perpetual pursuit for designing the best, cheapest, & best performing flyback (line transformer) driver, I've decided to try out some big BJTs, which appear to have higher voltage & current ratings @ considerably lower cost. In the past, I have tried MJE3055's, which work OK, and allow the generation of thin blue arcs from a 12V supply for a few minutes until the transistor dies due to high voltage kickback or overheating. The FDP33N25 gives good results but is somewhat unreliable at 24V. So I decided to give these alluring "PHE13009" 400V 12A rated NPN BJT's a try. However driving the transistor adequately seems to be the problem. (I didn't realize these transistors would require like 5A base current w/ only HFe of 2!) It seems like almost all the "good" driver schematics utilize large $$$ FETs or even IGBTs, but almost every CRT, plasma globe, and ballast (SMPS) I took apart seem to prefer high power BJTs probably due to this exact cost difference. I was only able to get simalar performance to my 33N25 MOSFET when I stuck an additional TIP120 in as an additional darlington stage, which worked very nicely (white hot arcs) for about 1 second, then it popped! :( Since the collectors are tied together they are all exposed to >200V transients, I am sure that's what killed it. I substituted that transistor for another PHE13009 to see what would happen and with a third driving stage (2N2222) I could get somewhat acceptable results but I know I can do better. >:) - My actual questions:  * The GDP of this transistor is 40MHz, seems fast to me. (certainly faster than the 2MHz GDP of the 2N3055 which works well in my slayer exciter.) and MOSFETs have significant gate charge. ECE2630 glossed over transistors mentioning BJTs are faster, (small signal ones, anyway :P ) and some internet sources agree, but I am finding lots of sources saying the opposite! What's the deal? Which one "faster?"  * How to traditional BJTs compare to IBGTs? Which are faster/better? The datasheet for this transistor explicitly mentions its use for "high frequency ballast and switch mode applications" which implies that it is well suited for my needs. It also includes a several inductor test circuits, but other than that the datasheet is pretty bare-bones.  I'm actually a little disappointed the HFe is so low (around 2-3) @ >10A. I may require more windings on my primary and a 48v supply. (not ideal) * I know I will dissipate a little more heat due to the base current, and something I didn't consider was heat dissipated in the resistor biasing/controlling the base. (like 12V at several amps just to drive the damn thing!!) so it is worth the cost benefit of $0.5? Is there a configuration I could use that makes driving the transistor easier?
