Inside a cheap Neon flicker-flame lamp from eBay.

- Опубликовано: 30 янв 2017
- While looking absolutely nothing like a real flame, the neon flicker flame lamps are strangely pleasing to look at. This is one that came directly from China via eBay, and had a very intriguing manufacturing fault.
I'm guessing that the reason the electrodes went white when the lamp was opened is because they also have the function of a getter which absorbs residual oxygen in the lamp. I can't find anything about the electrode material or coating online though. I do have some different lamps that have shiny metal flame electrodes, but they gradually reduced in the flickering effect over time.

"The vice of knowledge. [glass cracks] Ah, it's just released the knowledge." - love it.
Reminds me of my old history teacher at school in the 1970s when corporal punishment (hitting the culprit's bottom with a trainer shoe or a cane) was still legal. He used to threaten that he would apply "the staff of knowledge to the seat of understanding".
I swear that calculator gets bigger every time I see it!
not so sure its A4 size like mine
lol. I did not noticed, had to recheck it :D that's a CALCULATOR :D
Maybe BigClive's hands are shrinking ...?
I feel the same about your mother
can it do bigger sums because it's bigger ?
the small glass bulb contains a mixture of neon and other gases at a low pressure and two electrodes (an anode and a cathode).
When sufficient voltage is applied and sufficient current is supplied between the electrodes, the lamp produces an orange glow discharge.
a small amount of ammonia is added to the electrodes keeping the arc from covering the entire anode and cathode.
the arc is smaller than the anode or cathode so it tends to jump all over the surfaces making the flicker you see.
when you broke the bulb the ammonia-oxidizing.
15:28 "Black-black-black color code of a resistor - it means that it was cooking-hot"
yes it cooked the orange colours to browny brown
Cookie hot. =P
it would eventually go back to being a nice glowing orange when it burnt out completely ! briefly
Black is the new orange :)
is that so !
In the 1970s the early home 600W lamp dimmers used a neon bulb instead of a diac to fire the triac. I made a set of six flickering dimmers by replacing the neon trigger lamps with these flicker bulbs, then wired them out to incandescent lamps in the building chandeliers. Worked quite nicely.
I bought two for $1.50 each at Walmart, sold near Halloween as a novelty. They were surprisingly nice, having a clear standard globe rather that the flame-shaped "candelabra" shape. They draw a mere 3 watts.. And are said to last 2000 hours.
"It was being grilled. It wasn't having a good time!" LOL !!
Fastest oxidizing material I have seen... from black to gray/white in a minute.
my barbecue briquettes do that in seconds - best observed in bright sunlight with a brisk sou'westerly gusting to 35 Knots.
Reminds me of what goes black, white, black, white, red? (Something to do with a set of stairs, gravity, a nun and a sharp instrument.)
The common barbecue charcoal briquette sold in stores contains lime as an indicator agent, which is why the briquette turns a uniform white color when burned.
Natural charcoal will not turn a white color when burned, you'll either get grey ash or black dust when combustion is finished.
The briquette contains clay. as a binder, to increase heat capacity and probably slow the burn. but nirmal charcoal also makes white ash. These are the minerals, e.g. potassium (carbonate)
Have you ever smashed a radio valve (USA esp. "tube") and watched the gettering go from shiny metallic black to powdery white in a couple of seconds?
@@28YorkshireRose12 yes I have seen that happen after dropping it.
Somebody else I have to drop another one once for some reason I like a paint can or something like that or something somewhere full of water hit the edge when the tube got dropped this was a different tube of course part of the to move at least that was still attached to the base contain the get her and all that the actual get her ring that wound up in the water and actually started fizzing that was rather unusual thing to see wonder what the physics behind it that is or at least the chemistry
Alec (Technology Connections) sent me over, after he posted a video about these today and I haven't seen them in use anywhere nor thought about the effect being used intentionally for several decades. The only thought of mine after watching this though: seems like less of a current-limiting resistor, and more of a thermal fuse/product lifetime-limiting resistor to me!
"what's the worst that can happen?" - Big Clive 1969-2017
Close... 1965.
big Bang and all the lights out in the street !
thehappylittlefox aka benji Thats more like Photonicinduction style... wizzard of light and darkness :)
but but 69' heheheh
A special year, atmospheric nuclear testing was banned, then you came along to make up for it. ;)
I did my best too, nearly blew my parents house up several times before age 13 and electrocuted myself at 2. Eavesdropped my elder brothers bedroom when they had girls visiting. Fun times!
Clive, you make the three hand solder look easy as pie.
I thought I'm weird because I love checking this kind of things but view on this video is giving me hope that I'm not alone! Good job Clive!
What a great idea for a channel. Thanks for the strangely entertaining content. I watch this stuff all day.
The theory about the releasing of knowledge is simply brilliant ! Love your accent, too! Do not think twice, subscribe now !! greetings from Italy
obviously the flicker is caused by the battle of good versus evil!
Good being the cheap Chinese neon lamp, evil being the iPad. Am i right?
its the remnants of a long ago star wars light sabre battle !
@@thehappylittlefoxakabenji8154 think that's what they're getting at I believe
I stumbled across this one again after about three years.
I forgot I had purchased some of these for use in my industrial lamps.
It was nice seeing this again, but bittersweet that you got an incorrectly assembled one.
Good thing they are super cheap.
My guess would be the electrodes have a coating with a low work function mixture of something like BaO2/BaCO2/Ba, like in neon signs. If that's the case, the change you saw was likely the amorphous barium oxidising.
Edit: 10mintwo correctly pointed out that a barium azide/nitride combination can also be used to form the amorphous coating.
Loving the grumpy/annoyed candle doodle Clive!!
lol, I love that I'm not the only one with a light bulb collection.
I actually have some of those light bulbs that were used in The LCD watches before like the Indiglo watch came out subminiature linear incandescent.
There are some miniature bulbs similar still available evidently but they're very hard to find and Specialty they use them sometimes in model railroading I bet you those things probably cost less than those because of the quantity they were used in I've got both still plus a lot of the older grain of wheat and grain of rice bulbs that were 1.5 volts and 3 volts as well got some do filled it ones as well but vary in voltages that stuff I saved whatever I could get it.
I'm into Lego adults have Lego actually I found it those miniature bulbs fit easily through the holes in like a headlight right angle breaks.
I've used it to create working like lamps and all for the like of sit-ups yeah not entirely a purist obviously.
Cutting Gorilla Glue Sakura Edge I know but when you do something custom it's okay in my book.
I even have a box with a built with flicker LEDs from flickering LED candles to do fireplaces.
Also a lot of those I recovered from Dickens Village and like Department 56 like stuff like that interpreted the subminiature incandescent NYSEG use they already had leads attached as well
In addition back in the old days where that was mainly what was used really before there were white LEDs which at a time did not exist.
But the often used Amber LEDs once those things start going LED.
But the great thing about the incandescent as you could run them on sit-in series to match other voltages you're using even running on the official Lego system voltage.
And also under running them on that as well would increase lifetime but don't know what they read but I didn't want to push it at all.
Also I remember at the fabric store running across these modules that were meant for lighting various things hobby shops as well they had groups of I think it was 10 some major incandescents double A battery pack also there were some that had Chaser circuits on them noticed it always start in the same position same bulb every time.
Upon applying power.
Antop home I could put that to use.
By the way there are five groups of two flashed in sequence.
Think you get where I'm going movie theater with working Marquis.
Later on once I became available I was able to do that hundred percent Lego with the Lego fiber optic system in a motor there you go hundred percent by go chasing Marquee lights unfortunately just in red oh well but it was 100% Lego
The black coating is barium, I believe, both elemental and with traces of barium nitride, the former readily oxidizing in air as you observed. It's not terribly good for you, but I doubt such a tiny amount could cause any harm.
If you think about it these are sold to home and apartment renters in the local home and hardware stores, and they don't have big orange warning labels wrapped around them that say DANGER! PROFESSIONAL USE ONLY! SUPER TOXIC RISK! USE ONLY IN APPROVED BLASTPROOF SOLID LEAD FIXTURES!
Something like this is going to occasionally get broken around a home, even if there are babies present. And yet the department of Health and Coddling lets them be sold. They can't be all that deadly in small quantities.
Yes, and fluorescent tubes tubes contain a small amount of mercury. It's all about likelihood of causing harm. With lethal doses being 3-5 g of even the most soluble Barium compounds it is extremely unlikely to cause harm. In the UK there are actually rules around fluorescent tubes that a lot of people are not aware of. It is illegal to intentionally break a fluorescent tube, if you are a business you must store used tubes in a safe and secure manner ready for recycling, tubes may not enter landfill - they must be recycled. Technically an energy saving lamp (the type with the folded tubes) are CFL - Compact FLuorescent or CCFL - Cold Cathode FLuorescent lamps and must be handled the same way. So who here just throws them in the bin?
The other distinction to be made is that a lot of heavy metal compounds remain in the body and have a cumulative toxic effect (this is particularly true of Mercury and Lead, this is why there is so much concern over water contamination of these metals and their compounds) many Barium compounds on the other hand leave the body so the effect does not build up over time.
Impressed by the one handed soldering
Excellent demonstration, always wanted to do everything you did, thanks champ!
Wow...I've never seen a flicker light quite like this one. I love the fact that it has two light-producing panels back to back and slightly offset from each other as it creates a sense of depth like a real flame. Most of the ones I find in stores around me simply have an led or element which is pulsed "randomly" which looks OK I suppose but this thing is amazing.
I agree with you! I wish be had sacrificed one of the non-defective bulbs, this one was unique, and virtually impossible to replace!
my favorite Cliveism is OK let's take it to bits. brings a grin to my face everytime.
Ditto
Hello Clive , have to say Ive just realised having been listening you your videos in the background you have an incredibly amazing voice , you should do a Radio show , even my Greyhounds are just relaxed and sleepy , love your vids by the way , thanks for taking the time to post them
I always love the way all that wisdom gushes out of things when Clive pops them open. I have been wondering how best to collect and store that stuff though, it's clear, colourless, odourless, and you can neither taste it, nor touch it. It's like ectoplasm, and just as hard to contain!
I used to love Halloween when we would put those bulbs in various lights in and around the house! Such a cool look!
I have one of these lamps in my basement and ita over 30-40 years old and works just fine and glows on both sides and is very bright and cozy
Fascinating....thanks Clive! 🔥
That was extremely cool!
I have a neon bulb that looks like an 8-ball but it doesn't flicker.
Now I want to make it flicker.
US has 120v and 240v. Common mistake that they only have 120v. Do love your channel content sir.
"You know, we could do another experiment here. We *could* do the *diode* experiment! Let's do the diode experiment, because I do have a diode."
Oh you do!? Really? Shocking! Hahaha! Keep up the great work, sir.
I'm the guy who told you that about the aluminum soldering trick, and i need to point out that it ONLY works with lead free solder, preferably pure tin solder with no flux. And a small blowtorch is needed for larger pieces of aluminum.
thank you for posting and explaining.
In my experience, the oil isn't *strictly* necessary for soldering to aluminum. Like you mention, the oil's purpose is to protect the aluminum from oxidizing again immediately after you scrub it. With a generous enough blob of solder, it'll protect it the same while you scrape the top layer with the iron either lightly or with a iron/tip you don't really care about (the $20 radio shack fire hazard I've had the same tip in for 15 years works great for that).
I use it quite a bit for simple prototyping if I don't have quite the right component handy. I always have empty cans laying around, so 5 seconds with a razor knife and some cheap harbor freight cutters, and I've got a quick'n'dirty button or battery terminal or whatever and can get back to proving to myself that the thing I want to build actually works while I wait for shipping on real parts.
Solder with a touch of magnesium added might work.
Or an argon/nitrogen nozzle on the iron tip...
It would have been easier to solder onto the blob of solder next to the glass.
I bought my QuickTest at Newark Electronics in the US. It broke when I attempted to connect the AC cord to it. I was not using excessive force. If you get one be very careful to not over-torque the screws.
whatever was coating the electrodes it definitely started oxidising as soon as you cracked the glass so I dont think you can really tell anything from the resistance measurements after its encounter with the vice
yeme Yeah I thought the same. And they also kept getting dodgier by the minute. Pretty sure it's mildly toxic if not extremely. XD
Perhaps a barium coating of some kind? Certainly acted like the barium getter in a vacuum tube when exposed to air...
I'm glad you made this video. I bought a few and they all arrived smashed and broken :(
Places like Home Depot still have these neon flicker bulbs with the chandelier bulbs.
Yes you can solder to small and thin aluminium parts. Obviously it has to be up to temperature, then you just scrub the daylights out of a very small area with your soldering iron tip, while completely smothering the job with molten solder and flux. Could take upwards of a minute or so.
first time to comment on this channel since been watching for nearly 3 years now. but i have a bulb like that one but only difference is its way old and rarely used its got to be at least 12 years old and flame is more excited bit more detailed surprisingly for its age
I love the way your calculator makes it look like your in the old tv series 'Land of the Giants'!
Frankly I haven't heard of that one Land of the Giants but I do actually have the like Sid and Marty Krofft oh there's pretty much especially HR pufnstuf I'm sure you may have heard or at least some people have about the stink they put up with McDonald's and their large puppets the off the McDonald Land commercials mostly I think it was yeah that could easily happen eventually just like with their issue with their theme song and the the song feeling groovy I think that was the one that was based on the same tune sort of can't remember quite right but yeah something wrong that lines
they had this style of light for $0.40 at walmart because Halloween just ended so I bought 3 and came straight home too find the big clive video on them I knew had to already exist
Neat! Ordered one just because I'm curious to see what the flame looks like irl.
The aliexpress seller called the electrodes "aluminum material" but there's no way of knowing if that is accurate, they also call them LEDs so there is that.
I use these in my Pumpkins every year. I've been using them since I was a tiny child they really are cool I also have them in c7 strings on my porch arches. I've seen them here in c7 c9 flame shape and A19. There were other bulbs here that were unique too that had like designs in them I have a pumpkin "Orange" and Christmas tree "green" one "they didn't flicker". I don't know what they are called but it seems to sound like what your describing as a neon indicator lamp. Ill try to find the box later as I kept the original package.
Also I hope to move to Norway on day and will be bringing some of my Favourite decorations. I will be using step downs that way I can still use everything. I don't think the 50hz will be a concern for the lights. Also I don't have to worry too much about polarisation as most of my lights don't use it and the ones that do only use one fuse vs the two fuses on the non polarised.
I had to read the box twice to establish what type of bulb it was....apparently its an F-L-I-C-K-E-R bulb.
I've obviously missed a golden opportunity to fill in between the L and I with a Sharpie.
bigclivedotcom Clive, you might have just opened whole new markets for those bulbs.
it's A* flicker bulb.
I'm kinda curious now if these could be lit without the flicker when slightly over driving them. Old neon light bulbs for regular lighting, like war time blackout lights (such as beehive lamp), are rather hard to find and a bit expensive for my budget.
Possibly, but electrode seems optimised to flicker.
1 handed soldering, you pro you 😀
Apparently, these type of bulbs require a very slight amount of heating and twisting of those elements in order to get the flicker effect. One way to verify this would be to shine a high power laser pointer at the elements while the bulb was on to see if the flicker pattern changes.
You don't need a laser. We've got several of these lamps in candelabra holders either side of the fireplace (put there by the previous owners of the house). We noticed that one of the lamps just glows steadily and doesn't flicker, and I'd heard that light tended to aid the discharge so I shone an LED torch at it, and the flickering perked up.
Other tests: Bringing my (probably fairly earthed) finger anywhere near the bulb altered the discharge pattern. But the best thing was to hit the bulb (gently: not hard enough to "release any knowledge"!) with an insulated rod (the handle of a screwdriver) which made the electrodes vibrate without the electrostatic effect of the earthed finger. The vibrating plates produced a tremendous discharge - presumably as the gap between them reduced and increased, affecting the striking voltage.
17:30 you definitely hit something 😆 * workshop ASMR *
i bought one an it have run on a timer now for 1 month (9pm-6am) not heating the socket that much. thanks for the vid because i need to order more now that i know that it works
surprisingly how much it changed colour once you broke open the glass bulb. Thanks for another interesting video
I also loved these when I was a kid
Yep oftentimes would see those in Windows lamps that would have the socket wired for two different sockets and support or through a switch either both on either one or off and typically you'd have a flame bulb down into lower although I used to use one of those two headed like a 7 watt night light bulb in it just for a little of white so you don't trip over anything it was pretty dark in the then where I stayed downstairs that lamp actually needed a new socket and switch is how I got it one day upgrade to a different lamp.
Eventually I want to do with those voltage regular night light that used to be on voltage regulator tube as the night light bulb voltage doubler perhaps the resistor is well or otherwise build into something like compact fluorescent base and put that in that socket and when those lamps there you go
+bigclivedotcom It would be interesting to see a review of an electric fireplace. A friend's dad wired an outlet backward and when he used one the flame "animation" was backward.
“Oh, it just released the knowledge...”
The box is branded Lindner, a former high quality brand from Germany that become part of Philips
I've got an original black Safeblock (old name of Quicktest) with metal pins that have coloured dots on them for identification. The colours are red, black and green so it's pretty old.
An interesting detail i noticed is that the American standard are the same as some older type of standards (especially in vehicles and machines) in My country, my guess is that american standard was used parralell with the Europa standard back in time, probably to make the intallation of imported US made items easier.
The electrodes act like a getter and are probably coated in barium, they should fizz when put in water if there is still some barium left.
"What's the worst that could happen?" Big Clive in almost every video.
The color code is black-black-black-black, that made my day :D
Back in the 80s my Grandfather's dining room chandelier had these in it. If i remember It was on a Dimmer Switch and Able to Turn The Flame Down or Up like a Real Flame. Us
At some point in time can we get a Big Clive gore compilation!?!? lol Love your channel either way! :)
Oddly enough, looking on the US Amazon site they only seem to carry the European version of the "Cliff QuickTest" (single and three phase), using that search term, for sale in the US market, which is a bummer as I was quite excited when you mentioned they were now available in US and Canadian standard conductor colors. Perhaps the US and Canadian versions are only available in European markets and will have to be imported from Europe (which seems a bit silly and less than an optimal sales strategy for a North American oriented product)? I would very much love to add one to my electronics workbench one of these days as they are considerably safer than wire nuts or alligator clips!
Like you, I also fell in love with these neon flicker flame bulbs as a child. I can still remember how fascinated I was when I first came across them in a retail store, a shoe store if I recall, while shopping at the mall as a young child and being absolutely fascinated with the way they could mimic a flickering flame. So you can guess what I had to buy a bunch of when I became an adult and was decorating my first apartment for Christmas many years ago!
I have the US/Canadian version back in stock www.ebay.com/itm/Cliff-QuickTest-in-US-Canada-Wire-Colors-/302263880948
I got one of those cheapo meters from CPC for under £3 ( approx 5US $ ) aside from being flimsy they only have a 1 Mohm input resistance instead of the usual 10Mohm.
OMG..... of all the videos this one felt like Clive was going to get a shock!
I went to check out the US version of the quick test (it's model number CL1857 for anyone interested) and it seems the only place that even has them listed for sale is Farnell, and according to their website they're out of stock and won't get a new batch until March, plus they want a $20 "freight" charge due to having to ship from the UK. Oh well...
I have the US/Canadian version back in stock www.ebay.com/itm/Cliff-QuickTest-in-US-Canada-Wire-Colors-/302263880948
Most of the delays is the manufacturing lead time from Cliff. When I put in an order it can be as long as a month or more before they are ready to ship.
those rotary resistors are great!
So what would if you replaced the diode with a full bridge diode ? One side would light but would it be steady and not flickering ?
Technology Connections just did a video about these too!
Have you seen the cost of resistor substitution boxes lately? I bought mine in Lisle Street in Soho - shop between two brothels, those were the days! You reminded me that I have lost my box, thanks! 😣
Is "lost my box" some weird euphemism for what happened to you in one of the brothels? ;-)
Ordered from the same seller and expecting it to arrive any moment now. Hope mine's OK :)
color code: black, black, black, black!
Actually, I have seen a zero ohm resistor with a single black band. en.wikipedia.org/wiki/Zero-ohm_link
yes they exist its just to hide a poor pcb design your not supposed to have crossovers on tracks
Same reason applies to through hole components I think.
simontay1984
nope through hole components can be placed by machines as well.
They exist just so links can be placed by the same machine that puts resistors. This supposedly saves time, energy and space as you need less machinery.
I was wondering how much time would take Clive to post a video about neon flicker candles :D
Thanks for this Clive - I was mesmerised by my flickering bulbs and suddenly wondered how they worked. Still wondering why use a resistor rather than run several sets of electrodes in series. Perhaps not enough room in the bulb, and the "hot" neon might do something weird too if there were extra electrodes to discharge to. Anyway, got me thinking! 👍🏻
A decent margin is needed across the resistor to regulate the current. Without it the neon would literally pass as much current as it could.
@@bigclivedotcom of course: Neon might have a ~50V drop but probably doesn't obey Ohm's Law. Got it. Thanks!
Hi. That strobe effect due to filming got me thinking. Could you look into how camera phones work in conjunction with their backlight/flash. The camera films at about 24 to 30 frames per second, I think, and the LED flash can be used as a backlight in some models, giving some very strange results as I think the LED has its own flashing rate. I note when I am filming and there is a mirror, the dust on the mirror will have a series of rainbow type bands, like the interference pattern on a diffraction grating per lots of fun in O Grade Physics. The pattern is only visible on the mirror on the camera screen and not the on the actual mirror in front of you.
This effect only happens with the light of the camera being used. It happens with various cameras and their lights but does not happen with any separate light, no matter what the colour temperature either.
This is also good for capturing these orbs that Britain's Most Haunted catch with their infra red. But with your own camera: have it on movie mode with backlight on, point and shoot. It's worked insofar as I could capture lots of orb things which were visible only on the screen in the light but not visible in front of you in the same light. Notwithstanding the ethereal verities of what is actually being filmed, the point is I'd like to know HOW it is being filmed. The dirty mirror is an obvious clue, and the strobe effect here reminded me.
Clive won't cut himself with the lamp and the resistor will be 47K
my school uses these lamps for christmas because our school has a big christmas tree where these lamps are used in
Maybe the electrodes are stacked that way because they are all stamped with the same die from the same sheet? Otherwise they'd need to be mirrored pairs to line up and have the dark sides together. This is assuming that there really are dark and light sides.
you are the man!! keep up these dodgey things that people don't know i bet from your videos that you have saved more life's than a Dr has ever done . keep up what your doing and get these fakes off eBay in court for dangerous product act
In this episode: Big Clive use the power of the Vice of Knowledge and the Snip of Armageddon to annihilate Neon Flicker-Flame.
You still can't solder aluminium just by using oil (or scraping as you solder). The solder _will_ stick, but it won't last. Less than a week later in the case of scraping it will fall off, because you can't really stop oxygen diffusing into the join, which is by no means completely wet by 60/40. Oil might last longer, but I doubt strongly it would last even a year. You need a special solder which wets the aluminium properly, which is available, apparently.
I think it's flickering because of when the plasma heat up 1 electrode then it will expand and get far from the other electrode thus make it disconnect temporary until it cool down enough to come closer in the length it can arc?
The coating on the electrodes is 'getter' this is to keep the purity of the neon. The electrodes of good quality neon and argon negative discharge lamps are fabricated from Swedish iron for its low sputtering qualities. Cheapie lamps aren't made with Swedish iron and as a result blacken quickly. It's interesting to note that prolite for a few years had a low cost 'flicker flame' that didn't have the getter coating (barium I believe) on the electrodes (they appeared shiny metal). As a result the discharge was a lot dimmer due to impurities in the neon, also if ran on DC one side of the electrode lit pink and the other lit pale blue!
I may have some of those shiny flame lamps somewhere. When left running they settled down and stopped being so active.
bigclivedotcom yeah they do that! Also they don't always light immediately. Have you tried running them on DC? I've toyed with the idea of removing the cap from one and using it to indicate polarity.
Can I ask a really silly question? Why did you solder the wires onto the tip/cap of the bulb? Why not cut the lead to the bulb holder and then connect the variable resistor in series with one of the wires using screw-block connectors?
I think the electrodes are raw untreated iron. Only the negative side glows because it is emitting electrons
Pure iron wouldn't have oxidized a white coating within seconds of being opened though.
Maybe they are iron electrodes, but coated with something else? Possibly an emissive coating similar to what is used on the electrodes of fluorescent tubes.
Sebastian Rietig the outside of both flame parts should glow, this one had been assembled wrong, causing the outside of one and the inside of the other to glow.
It's a shame you sacrificed the defective one!!! It was unique and will be hard to replace...
If you lowered the light in the room, might the camera slow down the shutter speed to compensate?
The Cat Behaviour Channel
No, the iPad is fixed at 30fps. In lower light it would increase the exposure level but not the frame rate, which is optimised for 60Hz mains in the US.
@@WaltonPete frame rate != exposure time, which can be up to 1/2 the frame rate.
Resister wheel from Jaycar www.jaycar.com.au/resistance-wheel/p/RR0700
I dare people to build their own resistor substitution box or a better one called a resistor decade box. I have parts already on the way for mine. It would also be fun if he could show us how to build one as I am sure he has most of the items laying around the shop and they are dead easy to build from the way i understand it and the one I am building has almost any resistance you want to dial in. it contains 63 resistors with in my case with thumb wheel switches and with this setup I could dial in any resistance that I wanted and then find the appropriate capacitor in the standard capacitor range.
For me at least, the challenges are, the box/shell, internal wiper contacts and nice silk screened labels to get a pro look. obviously it can be made without those or made with an off the shelf rotary multi contact switch. but won't be as compact or user friendly
also, it would be neat to make a more compact one with smd resistors
The easiest way would be a breadboard with a load of resistors in with one end commoned to a lead with a croc clip then another croc clip lead with a jumper pin on the end. Ugly but functional.
I suppose. but then again if you don't want to keep the single wheel format, you might as well buy a few of these and make a proper switch box. they are fairly cheap and compact

Thanks vk3hau, as soon as I saw it I knew I MUST HAVE ONE OF THESE! :-)
Too bad it's still forty bucks; someone ought to have figured out how to make them cheaper by now…
moot now the vice of knowledge has done it's work, but doesn't the fone-cam suffer from less strobe/flicker if you dim the bench lighting down a bit?
Where do we find the AC terminal box you use in all your videos Clive? Looks like a very handy tool!
It's a device called a Quick Test. Now available in US and European colours.
Andrew J McKeown bro you liking your own comment and shit, ain't nobody wanna pay $60 for that shit.
Hello from Technology Connections in 2022
I see Fanny Flambeaux doing the rounds on Facebook again, Clive. I hope it leads to more views & subs for you.
See this 1966 patent for this flickering flame lamp design:
www.g3ynh.info/disch_tube/lamp/patents/US3238408.pdf
From a very quick scan of the patent documents, the inventor used Barium Azide to coat a nickel plated (??) iron electrodes, which are subsequently subjected to a number of processes before placing it into the lamp. Although I'm not entirely certain what results from those processes it appears they cook the nitrogen partially or nearly completely off leaving mostly Barium. I'm not a chemist. I'm also surmising that if only one side is coated with a material that lowers the strike threshold and the voltage kept low enough, only that side will glow.
John
will there be capacitance between the two electrode plates?
That Massive Calculator of Knowledge made me laugh.
Admittedly, I haven't seen all of your videos. But I was wondering why I always see you with a winding of soldering wire and never a spool. The only time you ever catch me soldering like that is because it didn't come with a spool, like silver solder kits.
Maybe it has a caesium coating on the electrodes or something weird like that?
10:00 yoooooo jaycar got noticed.... also sad now.. we dont have those resistance wheels anymore..
Technology Connections sent me here
Did the surface of the flickerer oxidize when you opened the bulb? The color seems to have changed. Edit: I asked just before you said it, apparently.
Interesting how those electrodes aren't symmetrical - in production they have to keep track of 2 different flame parts. If they designed it so they could flip them, they'd only have to make 1 part...
