Neon tube driver hacks

Ever fancied a real glass neon tube as an ornament in your home? With the progressive replacement of traditional neon signs with the short lifespan LED versions it's getting harder and harder to find a traditional neon making workshop.
The equipment used to make neon is quite complex and very expensive. Not just the vacuum pump and manifold system, but the very high power bombarders that heat the tube by passing a lot of current through the internal vacuum to burn out all the tubes internal surface impurities.
I strongly recommend saving any old neon signs that you can, or if you're lucky and find a neon workshop, then it may be viable to get a short custom tube made for ornamental use.
Neon signs require a high voltage, current limited supply. One of the cheapest and easiest ways to get a suitable low voltage version is to buy one of the CCFL (Cold Cathode Fluorescent Tube) drivers online. These ones seem quite well rated and are used for powering vehicle CCFL angel-eye tubes used as borders around headlights.
The hacks shown here allow you to customise the output to suit your tube. I kept saying nanofarad instead of picofarad. It's rare I use picofarad values. In this case they range between about 22pF to 47pF. It's interesting to note that in the PC-case cold cathode tube era, the short length tubes just had a lower value capacitor fitted in their drivers.
These power supplies are usually good for about 2' (600mm) of 12mm neon tube or a bit longer for the argon/mercury/phosphor tubes.
Over time I expect these power supplies to get rarer and rarer. So it might be worth grabbing one now. They're not that expensive at the moment. This one came from an AliExpress seller:-
www.aliexpress.com/item/10050...
A search for angel eye ccfl should find them.
Here's a UK seller who makes straight demo-tubes for collectors and educational establishments.
www.ebay.co.uk/itm/256366499235
Note that he can ONLY ship within the UK due to the destructive and expensive nature of international shipping.
I'll ask about and see if any of the USA neon benders are interested in putting some straight tubes (easier to ship) on eBay.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- www.bigclive.com/coffee.htm
This also keeps the channel independent of KZfaq's algorithm quirks, allowing it to be a bit more dangerous and naughty.

As a guy who bends and installs neon, hard to agree. LEDs literally solves all the things I hate about neon, and meet or exceed all of the things I love about neon. I hate the glass shards. I hate working with mercury. I hate burning my fingers. I hate inadvertently stepping on a hose and extinguishing a glass torch. I hate transporting them like they were the last piece of glass in the world. I hate repairing units that I broke pushing the trode into a PK. I hate getting shocked by high voltage. I hate lugging around 30 pound ballasts into ceiling plenums while playing The Floor is Lava off of a ladder. I don't love how neon is dim and miscolored for 5 to 10 minutes until the mercury heats up in the winter. Oh hell, I must be old and crochety now, I could go on like this for days.

A few days ago, I bid farewell to my neon glassblowing master. He passed away from cancer despite being quite young. He left behind his entire neon signs workshop, vacuum pumps, burners, phosphors, noble gases, and glass supplies. We had agreed before his illness to train me in using this equipment, but we only met twice. I learned to make bends, embed electrodes, welding tubes, but there wasn't enough time to learn how to operate the vacuum system. For now, I'm keeping all the equipment intact, but I don't know how long I'll be able to afford renting the space. Orders for neon glass ceased about three years ago, and since then, the neon market has essentially died out. So, even now, I don't see much sense in training, especially since the raw materials for neon production are now prohibitively expensive.

That was one of the things I looked for when I was interviewing people for work as assemblers. It is so easy to know who's a pro just by watching them strip a wire and soldering a connection. That or simply handing them a soldering iron and hand tools and asking them to set up their soldering station. It was a beautiful thing to watch a pro set up their soldering iron base in just the right position at just the right angle so they could put the iron back in the holder without ever glancing over at it. I watched 1 interviewee do that first thing and told them they were hired. They asked me if I wanted them to solder anything and I said, "No need." I also watch to see if they break off a short piece of solder with their hands or cut it off with their side-cutters. ( Breaking it off with their hand stretches the solder and squeezes the flux out of part of it, meaning that there's no flux in some of the solder.) Tricks of the trade.

I've been helping folks restore pads for DDR arcade machines for a few years now, and a common task is the removal of neon tubes. They originally came with 16 4" tubes in the pads, half pink half light blue. Most prefer LEDs these days, but I've always kept the old neons just since you can't get them anymore. Thanks for sharing some knowledge - I'll make sure to learn more before trying to turn them into art or something like that, but you've given me some great information as a jumping off point! Edit: didn't expect the dancing stage mention!! Huzzah, I feel recognized! A lot of the early 2000s rhythm games had them, too... Pop'n music, beatmania, guitar freaks, drummania... Usually they'd mainly be halo style lights within the subwoofer assemblies, with the occasional straight one hidden in for accents.

I'm sure you could ask them to just send you some lengths of tubing, although whether you'll get any benefit in pricing I don't know as those sign listings are priced by size, not by length of tube. Was a wonderful design by the way, a fire/icy rain yin-yang affair: White, blue, turquoise, red, orange, and yellow gas-filled tubing in pretty intricate patterns. Came with driver and EU power cord with UK adapter, and all mounted on a metal frame with both legs to stand it up on a shelf, and a chain to hang it from a wall fixture.

Question about the thinner size tube needing more voltage. Some Googling revealed that neon is about generating plasma in the tube. I suppose it's harder to maintain plasma through a thinner tube? (P.S. I just got my first lower voltage bench power supply and the first thing I checked was the ground through to mains. Thanks for all of the great safety tips, Clive.)

I remember my teenage years working in a late bar. I had a good relationship with the manager and he would let me program the 0-10v touch pad lighting desk wired to NJD Dimmer packs under the desk. It did everything in there. The pin spots (Par36) the floods, the par36 head scanners, the fancy effects (just motorised lenses spinning around on 3 axis) and most interestingly, the NEON! There were 4 rows of 2 phosphor pink and 2 blood red tubes lining the dance floor, a green pub name sign behind the bar and all the pink neon that lit all the seating areas. I used to have hours of fun on days off going up there and doing a live lighting show by dimming, chasing and beating to the music. It was much more enjoyable than just watching some pre programmed sequence running through, missing beats or not doing enough of one effect. I made it dynamic to the individual song being played. LOVED IT! Even got to keep a cheeky length of tube after a refit, but alas never had the skill to light it LOL Miss those days..Id dread to think how much power ran through there.

I've seen a new neon installation happening. True tubes and custom made. Could be made in Greece, but it was not being installed there.

I remember being really excited to get Angel Eyes for my Mini (not MINI) in the early 2000s. They were so expensive and there was a question over legality (at the time) so I never bothered. 😂

@<a href="#" class="seekto" data-time="390">6:30</a> you could have measured the capacitance on the wires, and they would effectively be in series, so it would halve the value, so doubling the measured value would give the cap value without dismantling it.

I really don't like LEDs as much as I used to because I feel people get very sloppy about using LEDs to light things well, and sometimes don't care when the colors are just horrible for the application. The loss of good esthetics actually looks far worse than I thought it could get in everyday places. Even the older displays that just used bare led dies as pixels were better than the crappy diffusers so often used. They are just token gestures all too often. It's about shaping the light and making it light up something evenly to the edges. I think of making neon and other types of displays that look as good as possible; as something I want to do just because I know how good they can look. And it seems this is becoming more important than just how I feel about it. I hope anyway.

Thanks for the insight into these drivers, Clive. I don't know if it's possible or practical, but it would be interesting to know what would happen if one of these driver modules was connected to different types of discharge lamp. There are quite a few ranging from street lighting lamps to various industrial and commercial lamps such as those used in retail outlets. Maybe a more powerful driver would be required or would there be quite a nice effect from being driven at a lower power?

@bigclivedotcom 25 күн бұрын

Driving discharge lamps at low power sometimes works, but there's a point where the electrodes suffer for not being hot and in an emmissive state. They sometimes sputter from a small point of light that moves about on them.

I'd be keen to get my paws on a few cold cathode tubes with noble gasses - got a fairly good vacuum pump and built an annealing furnace to make my own noble gas filled glass things but buying noble gasses in sensible quantities turns out to be very, very, very difficult... 🙈

I remember going to Piccadilly Circus in London way back in the 1970s and seeing then very large glass neon tube lighting up the side of the buildings and thinking that mush take some one hours or even days to make and bend then glass tubes. Now that art of glass bending must be dead and gone because now it's all LEDs powered signs. But still then where the days and things move on

How are we getting from 12v to something a transformer can use

@andymouse 25 күн бұрын

I wouldn't be bothered about the PSU for neon not to difficult to make and even the transformer is doable but the Tubes YES ! we must save them and make it a criminal offence to knowingly break one with penalties ranging from life upto death depending on the size and quantity of tubes damaged. Any opposition to this must be met with similar deterrents in mind and the artisans still making them protected at all costs, we cannot allow this art to be lost....cheers

I find the markings on the case interesting. "INPUT: 12V DC 50Hz" Perhaps I am just misunderstanding something, but that makes no sense to me.

Would this be able to be used in a “Jacob’s Ladder,” remember my dad connecting some thick copper wires to the output of a massive 110v powered neon transformer. I enjoyed the sight and sound of that arc move up.

This isn't high enough power. It needs a traditional neon sign transformer.

I remember years back getting demonetised on a video of my cat sticking her nose down a mole hole, she wasn't doing anything viscious, just sniffing it, but the algorithm back then (or whatever it was) decided nope, no money for you, not that it made any money even after it was remonetised, just youtube being dumb, as they still are, nothing wrong with miniature smoke machines being dismantled after all... :P
