Neat 120-240V chunky LED panel indicator light.

[@swjedi101]

i love how you always print out websites, please never stop doing that

[@bonarlibor3067]

Yes❤

[@bloodyl_uk]

Good to see I'm not the only one who had a wierd teenhood flicking through industrial catalogues marvelling at the weird and wonderful things in there, and maybe occasonally buying a panel indicator lamp or somesuch.

[@SonOfFurzehatt]

Just when you think you know all of the tools used in Clive's workshop, in comes the Wheel of Resistive Fortune.

[@stridermt2k]

Indicators are great geeky fun, and these are no exception. Good stuff as always, Clive!

[@jhc_fan]

Being able to understand resistor colour codes without a chart is a neat party trick

[@johnfrancisdoe1563]

JHC Fan It's a basic skill for those of us who learned before SMD components with written digits became dominant. The scale goes (0-9) black, brown, rainbow, grey, white. The rainbow is primary colors only (6 possibilities) and starts at red=2. The same color codes are/were used for other components.

[@therealjammit]

Bad Boys Rape Our Young Girls, But Violet Gives Willingly. Black Brown Red Orange Yellow Green Blue Violet Grey White. The dirtier it is, the quicker you remember it.

[@neiltonks]

You know, for 70% of the time I have no idea what Clive is in about. And yet I still sit here and listen to every single word. Maybe a little series of what a capacitor, resister etc etc actually do with a simple build showing it working. Please!

[@twocvbloke]

He's already done so: kzbin.info/www/bejne/bH7Eomh_rq2Gq8U :)

[@dbayboyds409]

Great Scott did a series on that too

[@darkbyte2005]

Just been to the fun fair and was looking at the lights on the walzter, all I could think about was Clive discribing the lighting circuit.

[@tonysansom]

"You might as well buy two" So Clive buys a dozen 😃

[@L30NBL4NK]

It's 1£ per unit. I bought 10 of them from this chinese supplier.

[@DiodeGoneWild]

I waited for you to crack the LED open and then the video ended :D. It could also be a single red LED and a bridge rectifier. This would have about the same 3.9V voltage drop.

[@bigclivedotcom]

It appears to be solidly potted in resin.

[@TheBlackadder-Edmund]

I also thought the LED was a goner... This deserves another video with the gutting of the LED... For science!

[@peterg.8245]

bigclivedotcom Never stopped you before

[@stonedsavage7814]

Peter Gettys he probably wants to keep them for future projects.

[@ipissed]

Probably because he is directly ripping off BC's ideas. Just look at the title questioning the high voltage generator as being a stun gun module. Conveniently 1 month after BC's video with practically the same title, just enough time to order one and full rip off BC.

[@pirateman1966]

I just love panel indicator lights. Always have.

[@andiyladdie3188]

I like that resistance wheel it is so small an compact, awww , pat pat, b.t.w the combination of light an orange sleeves makes image so pleasant and warm.

[@MonoManokit]

For those interested these appear to be either an AD11-25 or AD11-40 since the link is dead and they are quite stylish

[@raymondheath7668]

The mains connection block and the rotary resistor decade box were very interesting and useful looking tools

[@mickenoss]

3:25 ...I went and bought my official bigclivedotcom screwdriver yesterday, I am holding it now in salute!

[@JoshWeaverRC]

Some really good glue and tough plastic on an LED house lightbulb I recently took apart. The first tug of the bottom left just wires going to the pcb. I showed my daughter what not to do by putting the wires right into a socket and lighting up the bulb. Maybe she will listen and not direct wire things, maybe she will become an engineer like me.

[@PaulSteMarie]

Nice miniature resistor substitution box you've got there.

[@bigclivedotcom]

I got it many decades ago at Tandy.

[@badacktor]

oh please do a li'l video on those neon lamps too. I absolutely love those.

[@Roy_Tellason]

Common neons in my experience were the NE-2 (wiires) and NE-51 (bayonet base, similar to a #47 tungsten lamp). I never saw screw-in ones of the size you showed here. There were some bigger screw-in types, like the NE-45 ferinstance, I had a tape recorder (early 1960s vintage?) that used a couple of those for level indicators. But the last time I looked they were absurdly expensive...

[@thehappylittlefoxakabenji8154]

cool I like the indicators ,I have lots of vintage ones and I have a cliff connector thing too very useful

[@alankingvideo]

I’m surprised you haven’t removed the clip on that screwdriver, I think mine stayed on for about 5mins, as it never leaves my bench.

[@jayzo]

I remember seeing the Quicktest in a catalogue I got in the post from CPC.

[@SianaGearz]

Clive, you've never made a colour organ video, did you? I thought that would be a topic right up your alley.

[@bren106]

I notice you often refer to people asking about the various bits of kit you use such as the quicktest or the Hopi. Have you ever thought of doing a video going through some of them? I've seen the little circular resistor thingy (to use it's technical name) and would like to know more about it. It would be really handy to have a link to such a video in the description of any other video you make.

[@SmolPotatowo]

bren106 Pretty sure he has a video taking apart the quickest, not sure about the hopi

[@bigclivedotcom]

I've made videos about the quicktest and the resistor dial substitution box. Not the Hopi yet though.

[@uK8cvPAq]

They always run these neon resistors right at the top of their spec, most I find are basically dissipating the full 1/4w and run red hot inside their housing.

[@bigclivedotcom]

+uK8cvPAq That's why I recommend adding an external resistor.

[@uK8cvPAq]

Fair point, but when swapping burned out like for like indicators its not always practical to add them. The manufacturer should just do it right to begin with.

[@jonny393]

Yo all mighty Mr. Clive! Did you come across the (Jinhan) JDS3012A ? It's a ridiculously cheap handheld DMM and oscilloscope - you might be interested :D

[@gartmorn]

BHI eat your heart out! Takes me back to my power station days!

[@locouk]

I watched an old video about the fairy bridge on the IOM, is the tradition still carried out when people pass?

[@bigclivedotcom]

Yes it is. Mainly through fear of the consequences.

[@markm7991]

FYI in the US you can get a quicktest from newark.com, just got mine in, WHY DID I WAIT SO LONG.

[@preschau]

reselling2012 doesn't post to Australia :(

[@wavecreatures]

Nice one....would love to play a game of ‘Cards Against Humanity’ with Clive! 😂

[@ncc74656m]

"No tingles this time," Clive says in a tone of experience.

[@jamescorvett]

thanks for taring these open. simple as i thought they'd be.

[@AverageJoe2020]

Nice lamps, Anyone any idea where I could get eight red 2" diameter by about 2" high domed panel lamps?, Iv'e been looking for some for years to restore a conveyor control panel, Cheers, J.

[@silberwolfy]

Average Joe check ebay joe possable you can find them there chances are u might find the whole pannel your looking for

[@AverageJoe2020]

I certainly will, The originals are glass and extremely rare, I do know of one place I could get some but the Ministry of Defence would not be keen on me umm, borrowing them!, Thank you for your responce, J.

[@silberwolfy]

Average Joe. Lol i wouldent think so if you have an orginal one look into a place / glass blowers shop need you im shure that can make you some for a lil cash take the orginal if u have one to them

[@AverageJoe2020]

Nice idea, I will have to do a bit of research into that, Cheers, J.

[@simontay4851]

I have a box of old filament bulbs of various sizes and voltages that are unused. Can you provide a link to an image of what you're looking for?

[@160rpm]

I once bought a bunch of neon indicators, but they turned out to have an orange bulb in a green shell, so hardly any light got out lol

[@Capt_Schwartz]

Ouch, that buzzing, is that the cap making that noise?

[@Watchyn_Yarwood]

Zero listings/availability in the US

[@Lumibear.]

Clive, you’re my age, random ask, do you ever look at Top Of The Pops circa ‘75s-‘85s and think ‘Wow, they found a bit they can show’? ;)

[@bigclivedotcom]

Kenny Everett's dancers hot-gossip were even raunchier. I'm surprised they even allowed it back then.

[@Lumibear.]

bigclivedotcom Different times, Clive, different times, they’d be suing Kenny for sexual harassment these days. Also, in other news, I really must stop sending random thoughts out online when riotously drunk!

[@HighFidelityFox]

You should tear down one of those cheap aquarium pumps

[@stuc.6592]

[@HighFidelityFox]

Stooby Thanks for the link

[@AlphaMachina]

Could I run these LED's from USB power at 5v? Perhaps by changing the capacitor to a low voltage resistor?

[@lordRW]

hey, got a question can you do a video on how to recover powertool batterycells that are undercharged and are no longer accepted by the charger, how to fix it or check if you need to buy a new battery?

[@lordRW]

made a charger from one of my old PSU's charged it with the -12v and a +5v with at 0.1amp, but im gona be honest i have no clue what im doing here ahahhahaha

[@ihustleforit]

I dont know much about this stuff but i have a lot of old indicator lights....like the small ones you have there. Mine are glass though and some have bulbs in them. Is there any way i can test them with a 9 volt or an easy way to test them at home with normal batteries? If not what exactly do i need to test them out? They used to go to a bunch of HAM radio equipment. Thanks

[@bigclivedotcom]

They may have a voltage rating marked on them.

[@ihustleforit]

@@bigclivedotcom they do. it says 75w 125v but i still know noting about that lol. Will any regular batteries make the light come on to test them or what do i do exactly to see if they work? I dont even know what 75 w125 v means lol

[@CyberlightFG]

Has Clive done a Hopi review?

[@bigclivedotcom]

Not yet.

[@themaritimegirl]

I was interested in those neon indicators, but they don't have a 120V version. :'(

[@howdo5136]

The strike voltage on most neons is about 90V so they will probably light on 120V. Possibly with some flicker? If Clive happens to see this comment maybe he could test them and let you know? If they are only cheap, it might be worth buying some to try regardless and you can always change the neons as they are the screw in type.

[@themaritimegirl]

That was my first thought - just replacing the 230V neon lamps with 120V versions, but I can't find 120V screw-in neon lamps on eBay, either. -_-

[@bigclivedotcom]

They still light at 120V albeit at lower intensity, and should last for much longer than they would at 240V. I checked all the colours on my shaver socket and they looked OK. Not super bright, but still visibly lit. The best colours were orange and red.

[@themaritimegirl]

Thank you for testing that!

[@gregoriussoedharmo1206]

Do you have a video or can you make one that explains how to translate/make choke/coil from henry units in schematics?

[@johnfrancisdoe1563]

Gregorius Soedharmo It's basically number of turns around the ferrite / iron core multiplied by a number from the core's data sheet. Thickness of wire is dictated by the current capacity. If the wire leaves the coil at the opposite side, there's a half turn involved, like 10½, 2½ or even just ½ turn. If the shape isn't filled to the brim with windings, the constant will be slightly different. Usually it's easier to just buy a finished coil/choke though, leaving the details to the factory.

[@gregoriussoedharmo1206]

I'll give that a go, thanks!

[@wolfpax181]

We need someone to document and track the healing progress of your left thumb.

[@bigclivedotcom]

It appears that KZbin is already doing that. In every video it's a fraction of a millimetre higher.

[@w_callaghan8300]

what's that resistor disk called? seems handy and i could use it. where can i get one?

[@bigclivedotcom]

I got it about 30 years ago. Very hard to find, which is a shame as they're really useful.

[@catlover10192]

From what you've said before, the only way I could see you being awake at 7 am is if you hadn't been to bed yet.

[@bigclivedotcom]

I'm very nocturnal.

[@stinkycheese804]

What is so neat about a relatively huge, heavy part that does no more than the job of a smaller one? We could say that makes it more durable but how much durability is needed from the housing BEHIND a panel? With it that big you'd think they would make it a switch too, with the option whether it's lit when the switch is closed or open, then if you don't need the switch you just don't wire anything to the switch contacts. As far as this design goes, I find capacitive dropper LED arrangements to be short lived, decreasing in brightness drastically within a few hundreds of hours. Granted the ones I built used generic Chinese LEDs which are highly subject to quality variations and yet they were single chip LEDs ran below half their rated current. I can't argue with CHEAP, except that when the lifespan is so low that it takes a greater value in labor to replace them, there was no real value in saving on the purchase cost.

[@PaulSteMarie]

Stinky Cheese 22mm is a standard size for industrial control panels. You can get a full range of modular switches and indicator lights that all drop into 22mm holes. You can usually gang multiple switch blocks onto an actuator to make switches up to 4P3T or thereabouts. These Chinese ones are crap, but Eaton, Omron, ABB, etc all make full ranges of components in this form factor.

[@johnfrancisdoe1563]

Stinky Cheese Also bigger lights are easier to see. Another comment was searching for an even bigger light (2" / 50mm) for an existing machine.

[@twocvbloke]

Yet another illuminating video, with a terrible pun left in a comment by myself... :P

[@soundadapter]

good work wish you a pleasant weekend best regards Frank

[@jp040759]

That doesn't look like an X or Y rated safety capacitor. Are those safe to use with a standard high voltage capacitor as built???

[@bigclivedotcom]

Many LED lamps contain the same style of metallised film capacitor rated at 400V.

[@jp040759]

I have seen that in many gadgets. Is that safe enough???? I want to use capacitive dropper supply for projects but I think I would use a fuse in line for safety.

[@CmdrRoot]

What is that rotating resistor selector called and where can I buy one?

[@bigclivedotcom]

I bought that about 30 years ago. I think they might still be available, but hard to find.

[@robbieaussievic]

..... not cheap , www.jaycar.com.au/resistance-wheel/p/RR0700

[@MrHack4never]

You should stick the name and brand of the quicktest onto it, and hope people stop asking

[@SlartiMarvinbartfast]

There's some supplier links in the comments of Clive's video where he took a closer look at the Quicktest: kzbin.info/www/bejne/lXW3nn9taNmbbbs

[@cheeseschrist2303]

Won't matter. People want to be spoon fed. Too lazy/no initiative to google or search ebay.

[@Graylord88]

What's the purpose of the capacitor in this setting?

[@matthewreynolds8025]

capacitive dropper to reduce mains voltage

[@bigclivedotcom]

It lets a portion of current past on each half wave and acts as an alternative to a resistor without the heat.

[@alexbabcock1880]

Source/product name for Resistor array at 5:00?

[@bigclivedotcom]

No longer made. It's very old.

[@bigclivedotcom]

There may be other sellers who do ship to other destinations.

[@TinkertubesLab]

So no package from Clive? :( Interestingly I didn't have much luck finding those indicators at german ebay. But I found them directly from china: www.aliexpress.com/item/Green-Round-Lamp-LED-Signal-Pilot-Lamp-Light-Bulb-AD11-25-40/32650647630.html Sadly, way more expensive. But i found those, which I personally find very interesting. Sure, also quite expensive, but stainless steel. www.aliexpress.com/item/16mm-Pilot-Lamp-PM16B-D-R-J-6V-S/1729333410.html I think I will grab a few of those.

[@superdau]

Forget german ebay for searching. Most sellers don't even list there.

[@anerek]

Glad to see your thumb hole is almost gone.

[@MrALCHEMIST2010]

If you do not bother to open the LED case itself then what is the point in guessing the possible four-diodes configuration on schematic. Sigh !

[@WaltonPete]

Those large indicator lamps are perfect for a 1970's style lair - for the discerning criminal mastermind. Wah, ha, ha, ha, ha, ha, ha!

[@markmodray7698]

I am surprised you didn't comment that a discharge resistor would make a much safer device. I guess you can't ask too much from Chinese crap.

[@bigclivedotcom]

The discharge resistor is usually used where a plug or lamp can be removed leaving the pins exposed. In an industrial application the indicator is hard wired in and may also be across a load that would shunt any residual charge.

[@SimonParkes]

Clive, your notebooks should be scanned and published, "BigClive_Pedia.com"

[@zachdemand4508]

Simon Parkes He does have a website. I don't know if he adds the contents of his notebook there. Last time I visited it was full of fun projects.

[@SimonParkes]

Yep, have downloaded a fair few of his projects... (My comment was tongue in cheek)

[@MrScotttraynor]

too bad not 12V... would be great for a computer case/etc...

[@superdau]

Didn't you watch the video?

[@MrScotttraynor]

yea i'm a idiot.. commented before finishing the video... /me *Pounds* head on wall

[@bigclivedotcom]

To convert to 12V all you need to do is short out the capacitor as the existing 1k2 resistor will be OK for 12V. For brighter illumination use a 470 ohm resistor instead.

[@MrScotttraynor]
