The flyback transformer does trigger the base of the NPN D882P transistor; the system naturally oscillates at 20kHz
Hey kas, Since i only have deconstructed & modified 5" and 8" plasma globe, i've just bought the small 3" globe that you've been playing. As i mentionned before, both 5" or 8" have their own IC oscillator hence not based on any signal coming from flyback trafo. One reason I'm interested to play with this small plasma globe is your above remark quoted. Is it possible for you to detail more precisely how it self-oscillates, the precise role of the flyback trafo, does some plasma energy inducted back signal is fed to maintain the oscillations. Any detailled info on this self-osciallting woudl be appreciated so i could save analysis & experimental time. Albert

Hi kas,

I suggest you develop an arduino software in order to explore different frequencies & duty cycle so you'll reach different resonances of your globe. At that moment, you'll realize it was worthwhile beyond just knowledge to have invested more than 200$ of equipment. To really make full exploratory, i suggest you also play with voltage control of your PSU because there is a sweet resonance plasma spot depending on a triplet <frequency, duty cycle, voltage>. Now, you'll also discover with professional isol-driver (IL610-MCP1403-IRF540) the resonance plasma impact of very sharp pulsing voltages impossible to obtain with a 4N25 and logig level fet smiley-wink

Sorry kas, i did not fully read your post #11 so yes, what you're doing is correct smiley-wink

I suggest you also try inverting polarity of LV side of trafo so you'll see diode effect hence different plasma tendrils eventhough you pulse same PSU pattern. In other words, you'll get either plasmic diode Kathode in center of globe or outer of globe.

What do you think about the 14.7V peak to peak as per scope diagram ?? back EMF ??
Where exactly in your circuiy scope view is plugged ?

Yes BEMF but you might also pick-up some Free Energy coming from iron core and / or plasma tendrils depending frequency so be careful to not damage some of your semiconductors components.

I shall publish soon a new video serie on my YouTube channel to extract & convert that BEMF so mosfet will remain COLD and many other applications so stay tuned.

P.S. Nice to see Corto Maltese smiley-wink

Hey kas, it seems your circuit is about pulsing on-off the plasma ball unit USB connector hence pulsing on-off the local oscillator inside plasma ball? If I'm right then I suggest you rather do the real stuff: remove inside plasma ball electronic then pulse directly the transformer with your driver. Happy New Year smiley

I don't vizualize or understand what plastic layer: maybe post a picture...
For me, the globe is in glass, not plastic !

For those of you interested to deconstruct 5" and 8" plasma ball all made in China, here are the trafo P/N: FBT-18 and BSM04-D02. I personally do not recommend using BSM04-D02 which has lower quality, tend to over heat if pushing frequency either up or down from its designed frequency. FBT-18 is much bigger & stable but ultimately, for those of you seriously interested in plasma engineering wether for visual entertainment or Zero Point Energy devices as i'm doing, best to build your own flyback trafo which then can really make sure of another issue raised by THINGS (corona destructive effect inside trafo). Always remember that when attempting Tesla Coil design, a HV trafo has an internal capacitor between windings so even if it looks like an inductor, it can become an incredible LC resonance circuit interacting either with backwards current through PSU via mosfet switching or plasmic diode & negative resistor smiley-wink

In all cases, always isolate signals between arduino pins and isolated-driver (mosfet or IGBT) otherwise HV could destroy arduino & computer connected via USB port to arduino.

I cannot say anything with USB plasma 3,5" globe & its associated trafo because I don't have one.

Nevertheless, I've long experience with 5" and 8" plasma globe where i use my own isol-drivers & freq gen so I can tell you no problem to push them high or low frequency.

Please visit my website http://www.youtube.com/user/selfonlypath but you're right, playing with such plasma & HV trafo tech can be very dangerous so best know the rules.

P.S. On 5" and 8", they do have a local oscillator but I throw them away.

Interesting, i did not see that specific comment of natural oscillation. I feel then the method you propose is just having arduino turn off or turn on that specific oscillation.

Personnaly, I rather generate HV via direct pulsing the frequency, pulse length & voltage amplitude. This gives access to a very wide range of plasma tendrils types but also optimizes the power supply versus level of plasma generated. To do this, i just deconstruct a standard plasma globe, only keep the globe & trafo then connect an isol-mosfet driver between arduino & trafo, the arduino generating whatever triplet (Frequency, duty cycle and amplitude ) of interest.

Hey retrolefty, what existing oscillation are you refering to ?

For more info of plasma management with application on wireless medecine and free energy, please see http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1256402716.

As a reminder, the real plasma secret is to control three parameters in order to make chaos or non-linear or parametric oscillators going beyond classical Maxwell equations of electro-magnetism:
- voltage amplitude of flyback transformer
- pulse length excitation
- frequency of pulse length

N.B. Plasma ball was patented by Nikola Tesla  in late 1800's as one plasma device without electrode wear & dangerous ozone O3 coming from air spark gaps.

P.S. Please be careful with fly-back transformer: very high voltage that can kill, strong Back-EMF so make sure to use isolator (4N25 or best IL610) between arduino pins output and mosfet or IGBT driver.

About science versus pseudo science applied to mysterious plasma behaviour, here is a new video with many electronics tips, theory food for thought on plasma ZPE engineering

Here is a new video with many electronics tips including first time double rail plasma driver fully controlled by arduino mega

Then more theory

so are you suggesting there is unlimited energy available, or that more energy is constantly being introduced?
I'm not suggesting what you just wrote above.

Please take time read first part of this thread http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1256402716/0 or watch my YouTube channel "Scalar waves / Design rules" on http://www.youtube.com/user/selfonlypath

Missing count of all energies is the problem !

It is quite easy to violate incorrect laws of physics smiley-wink

Many electromagnetic lab experiments prove that Mawxell equations are incorrect:
      - Aharonov-Bohm effect
      - Alsthuler-Aronov-Spivak effect
      - Josephon effect
      - Haas-van Alphen effect
      - Sagnac effect
      - ...

Wrong model, wrong conclusions.

Please watch some of my videos (ZPE design) describing how to extract Zero Point Energy via non-linear circuits. Most equations of physics have been linearized but this does not fully describe laws of Nature. If you keep linear model, you automatically get stuck with 2nd law of thermodynamics but non-linear systems or chaos systems or ZPE reactor can violate under certain cases the 2LT.
