USB plasma ball teardown and schematic.

[@ross302ci]

When i was a kid I had one of these with a setting that would make it "dance to music", where it would basically turn on in the presence of enough sound. I found out that if I hummed constantly so that it would be on, then touched my lips to it, it would shock my lips. I'm still not sure why. I love these things.

[@LucasGarrow]

When I was about 10, I remember setting a metal pocket knife on top of one of these and touching/drawing off a modest spark which burnt through paper. As I did this, the wireless door chime was 'activated' from the other side of the house. This makes sense now.

[@RK-1956]

The very 1st plasma balls I saw was back in the early '80s at an art exhibit. It was quite large, about 18-24" in diameter. And cost around $2700. It's amazing how cheap (low cost) and small these plasma balls are today.

[@pearz420]

Every since I was a kid I've found plasma globes very soothing and fascinating. I never got around to finding out how they worked. Neat video.

[@carlyonbay45]

Really enjoy these videos and your voice is almost hypnotic and very grounding . ..... and then you pull out the felt tip pen and notepad for the schematic - brilliant .

[@mostlysane77]

Commenting 4 years later :-) I found out years ago that if you balance a coin or metal object on the top of the globe a spark will jump from the top to your finger and burn you within a few millimetres. Alternatively if you place your hand on the globe then holder your finger near someone else a spark will burn you both. If you instead hold one leg of an LED and touch the other to the coin that will also light. and further if one person touches the globe and then hold one leg of the LED and another person holds the other leg the LED will still light. Great fun with Plasma globes!

In the hallway of my former highschool, there's a picture of me holding a lit full size fluorescent tube, drawing a massive arc from a Tesla coil we excited via a spark-gap cascade. Physics class was fun in the 80's.

[@gwesco]

In the mid-sixties, my HS era, we had a Van De Graff generator as well as a Tesla. It was great fun to form a human chain and touch one then have someone touch ground. Probably legislated away now for "public safety."

Speaking of Plasma Balls, & how they affect sensitive electronics..... I recall working at Radio Shack back in 1991, as a summer job, between my Junior & Senior Year in High School. We had a Plasma Ball on display on our counter, nearby our cheapest digital wrist watches. Some curious customer discovered that holding the face of the watch against the glass of the energized Plasma Ball would 'zap' the wrist watch. To our manager's dismay, pulling the batteries out of the watch & reinstalling them did not restore life to the watch. After that, the Plasma Ball got move to a safer location, far away from anything else electronic! :p

[@JopardBDS]

Thanks for doing this one Clive. I've been making custom housings for exactly these plasma globes for a few years now. I've not touched the electronics just stripped off the black plastic shell and replaced with my own. It's good to have a little more understanding as I hope to be a bit more experimental shortly with the same globes but different casing materials. In some ways it was quite fun listening to your assumptions on the internals when I knew what was inside

Yep that would be a good video. And then show after effects of doing that what it could do to a computer. There yet playlist of After Effects of funny things like that and I'm sure there are a few videos out there for like that or at least sections of repair videos regarding that. Not just USB port stuff but others as well or other equipment related to computers and run things being plugged that use some work connectors but different things going through them! Such as things that might have 24 volts are more on the same pinza something that would take about five or less. Yep d-sub connectors sometimes that'll do! Sort of like those USB decorations that well and those little USB vacuum cleaners that pole way more power than you should pull from computer USB! I saw at least one USB device once that melted a cheap USB extension! This is Fire 2 high speed charging! The current at 5 5 volts on the USB was over 3 amps for some reason still can't wear white was but you should have seen the size of that cable going to the USB plug! More look like a heavy duty extension cord than USB! What were they thinking! Oh and on that playlist and what not to plug into computer don't forget the USB killer! What next USB bug zapper! Actually I'm surprise we've not seen that from big quiet for anyone yet. Maybe it exists for just haven't seen it yet but sooner or later! I'm not just talkin about little night-light size thing I'm talking about football bug zapper like you'd hang outside that's a few feet tall. By the way good source for the nice high voltage Transformer! Once I tore one down it was an old one surprise filament winding vacuum tube rectifier didn't think it would be that old! Couldn't find any labels on it anywhere I'm probably long gone but yeah that exists! Once I saw one that instead of regular fluorescent ballast for the fluorescent tube there was actually what look like a ballast tube for a Old School radio. Even in an 8-pin tube/ relay socket About the point in this video where you guys are referring it sort of reminds me of ashens even tone of voice Etc for some reason don't know why

As she would say the the construction was similar to a light bulb with the right is on one can build a DIY plasma globe that uses a light bulb as the globe I'm planning on doing one eventually once I can find a suitable flyback Transformer. Harder and harder to find a black and white flybacks nowadays. Sure I could cannibalize a security monitor or something one of these days. Or maybe when those little black and white portable TVs or perhaps a Boombox with a TV in it who knows. Maybe they should have driver kits that could do this stuff that would have a signal Transformer 4 experiments like that of course legality of that is kind of a?

[@Andrew_Erickson]

This makes me think about building an entire room in my house with neon bulbs across the ceiling excited by HV power supplies

[@ChristopherWeaver1]

Science project here I come

[@aaronbrandenburg2441]

Actually at one time there was a predecessor to the fluorescent lighting system that sort of work that way except except larger-diameter glass tubes white neon tubes excited by high voltage. The interesting thing is the system was not sealed completely. And your ass was admitted through means that it would allow certain gases through it was quite complicated but it actually work pretty well from what I understand. Also the first Mercury lamps were essentially single phase Mercury Ark rectifiers but being used to produce light. And surprisingly enough they could even work on DC. But for the time that was pretty ingenious. Unfortunately don't have any links to anything on this but it does come from reading. This is mentioned in some Google books as well if anyone's interested. But good luck finding it I don't even know if anybody had mentioned on KZbin at all couldn't find much back when I first looked into it years ago

[@AdhamOhm]

These plasma globes haven't changed much, though they've gotten smaller. As a kid in the 90's I had an "Illuma-Storm Junior" from Radio Shack. As the name implies it was a smaller version of the original Illuma-Storm, but it was still bigger than the ones they make now. The cool thing about the Junior was that it had an Edison lamp base so it could be plugged in to any lamp socket, and you didn't have to use the stand it came with. I had mine in my bedroom's ceiling lamp for years. :)

[@imajeenyus42]

That's an amazingly simple circuit - I'll keep these in mind next time I'm after a HV source (or at the very least a transformer). Another interesting circuit is automotive HID igniters - they've got a little HV cap, spark gap and pulse trigger transformer to ignite the xenon bulb.

[@mattedwardsvintageelectron7754]

Looking into plasma balls for a prop, i stumbled upon these "usb' globes. Thanks for answering the "can i pull this thing apart without breaking it ?' ! This is going to be great!

[@JopardBDS]

I've been doing just the same for years. A doddle to pull apart. The worst but is getting the glass bulb out from it's rubber like O ring but not that bad as the glass feels pretty thick compared to say old incandescent bulbs. If you can I'd recommend pulling said ring from the hard plastic mounting (easily done) and using that as the interface of the prop for the physical mounting

[@Jedda73]

There used to be a huge plasma globe in the local museum when I was a kid. I used to prank unsuspecting people by putting a coin on top and watch them try to remove it.

[@ChristopherWeaver1]

Used to? ITS GONE?

[@hairypaulmm7wab195]

I have had loads of fun with plasma globes over the years & found most operate between about 15 to 25kHz. Some of the larger ones have produced quite strong near field RFI from around 10 to 80kHz.. (with spurious emissions across LF and lower HF HAM radio bands) If you run one above 100kHz you will find the larger current flow can burn your finger pretty quickly when the plasma arc is attracted to your finger on the globe. : Note: Placing a grounded electrode (I used a handy bit of 4mm CSA copper wire) on the glass it can heat the glass to melting point quite quickly! But this tends to end badly for the plasma globe. Enjoying your videos. Have fun Sir! :-)

[@VVerVVurm]

Clive try putting your solar desk calculator near it. If you find the right distance and let it sit there it will endlessly display random numbers and do all sorts of operations.. Years ago I used to freak out/annoy my coworkers by hiding such a globe under their desk and placing his calculator or his office telephone above so that the lc displays showed endless and weird activity. ;-)

[@gustavgnoettgen]

I had one and the glass broke after I put a penny on top of the glass as an electrode. I wouldn't have done that if I knew that I could just pull off to reveal the sturdy wire from the transformer. I used it as a lighter and to melt sand and salt grains onto larger beads which was fun. If you run the arc right at such grains they eventually heat up enough to conduct electricity so well that they heat up a lot, enough to melt.

[@phils4634]

Anyone remember the big one of these in the UK Science Museum (1970's?) I think it was about 3 feet or more across, and the "lightning bolts" were pretty spectacular. They also had a BIG (4 ft diameter) Whimshurst Machine, and the inevitable Van der Graaf - so plenty of sparks and arcs!!

Just pulled an 8 inch on of these out of the skip at work. Plugged it in to an spare 12v power supply and it worked straight away. :)

[@rogertopful]

What would happen if you raised or lowered the voltage going into the globe? Could you modify the board to allow a varying range of intensities or would it just stay the same?

[@SootySweep22]

rogertopful pretty sure you can drive them with much higher voltages. Photonicinduction has done a few videos where he does just that.

[@jameslmorehead]

I have one of these from a US supplier. Have taken it up to 12 volts. Much more than that and the little transistor gets too hot. The brightness and number of streams does change

Funny, I was just typing a question on whether that circuit would drive a neon tube single-endedly (just as you pulled that neon tube out). Several years back, I made an argon-tube light-sabre (30-36" long) with a similar power supply to drive the tube 'single-ended' to make the sabre extend and retract out of the handle. Cool stuff, thanks Clive!

[@SigEpBlue]

On the surface, it seems like a rough load for USB ports to handle, given its operating current, the noise, and that rather large filter capacitor on the input. I think I'll stick to my mains-connected neon transformer. ;) Thanks for the teardown, Clive!!

[@StuShoots]

We used to put foil on top and you'd get an arc to your finger, much like a bug zapper!

[@cassi75474]

If it has a jamming effect, the US Military should place these by enemy comms equipment, make things a lot easier.

[@PilchPlays]

Had one of those. Plugged in a 9V Wall Adapter to it. The wall adapter would actually put out 12V to 15V depending on load. Made the thing glow really well. Anyway the EM coming off of it killed my wireless keyboard. Always fun to put a layer of aluminum foil on the ball and try to touch it. Gives you nice little burnt pin pricks on your hand where the arch of electricity came off the foil.

I think they say something about that in the manual I believe and even sometimes on some warning label that might have been missing for one doesn't think to read either one. Sometimes rtfm is better in the first place if one doesn't know maybe one would know if that happens.

Hi Big Clive! ...... Little Clive here ...... again! 👍😂 These USB Plasma Globes are sold at ARGOS for £15.00, but mine was less than £7.00 direct from China via eBay! A set of Duracell Rechargeable Ni-Cd batteries lasted about 3 hours! As the batteries discharged, the streamers reduced in numbers, to practically nothing! Very underwhelming! 👎😂 My USB Plasma Globe is externally identical to yours, but different inside! The PCB is screwed to the upper case moulding, and on the top it has the transformer and an electrolytic, and on the bottom is a tiny surface mount transistor, and four other tiny surface mount components (resistors and capacitors). I cleaned the inside of the electrode tube, to stop streamers going into the base of the globe! I don't think people realise that the electrode is on the OUTSIDE of the globe, because it looks like it's on the INSIDE!

[@thomasesr]

if its RF frequency levels, could it be used as a antenna emitter for AM radio to play music?

[@AverageJoe2020]

Might be interesting to feed an audio signal into the primary of the transformer to see the effect?, J.

[@Electroblud]

eeeh. It is RF all right, but an extremely dirty waveform. I don't think it would be able to transmit music. However, it might give of a nice loud white-ish noise if you put a radio near it.

Or make a new one from scratch that can deliver a cleaner waveform and see if the music forms some sort of pattern...

What are the part numbers for the components?

My plasma ball graphite is quite blown. Is there anyway i can refill it

[@patriknilsson9154]

Hi Clive. Could you use the electronics in the plasma ball for a powder coating system?

[@bigclivedotcom]

No. It's AC output at high voltage. It might be possible to rectify it with suitable diodes/arrays.

Make this again and show the arc between a grounded screwdriver and the HV wire :)

Used to have a big mains powered plasma ball years ago in the late 80's into the 90's, just died in 1997 though might have went earlier if it was powered up more than once in a while. Hardly ever see them in the shops these days... though wax lava lamps made a comeback so there may be hope for the humble plasma balls.
