It isn’t often you actually laugh out loud when watching something on your own but when you got your magic wand out Clive that’s exactly what I did! Great video thank you.
ive gotten into a habit of watching your videos while eating my evening greek yogurt snack every day. the video lengths are usually quite good for that kind of thing. it's something relaxing to watch.
To a man with a hammer, every job looks like a nail... Gotta love a new LED lamp video. I just pulled one apart this afternoon after it had failed. A very common 9 watt unit here in Australia - an SAL lamp marked LT409. 16 little COBs with three parallel LEDs each, which turn on dimly at about 7.3 volts . All in series, 9V x 16 is about 144 volts. It appears to be a "proper" power supply though, as the first thing the power runs through is a FULL BRIDGE RECTIFIER and it uses an MT7812 constant current driver (8 pin SOP). Failure mode was *two* of the cobs had failed. We had a brown out and spike event the day before and I wonder if that had pushed it over the edge but I don't even know if the light was on at the time (probably was since wifey always turns that hall light on if she is home). That night when I turned it on it lit for about 1 second and then went off again forever. These things are a gold mine of high voltage parts like capacitors, diodes, chokes and transformers for an experimenter on a budget (not to mention some unusual COBs that you don't see on fleabay so often).
"I don't think this is gonna come out easily, so I'm gonna try..." grabs bulb with bare hands. I strongly resist the urge to yell at the computer. "You know, what I could do...." Performs Clive magic. Still tries to break off glass with bare hand. Like me, I think Clive was not closely supervised as a child - lol!
I enjoy watching these videos. They inspire me to learn electronics, and wish you had a channel where you teach electronics. More importantly the logic rather than the function i.e. some online courses will introduce electronic components, but don't help define what the component is used for. I'm a programmer by background, and understanding 'why' gives one room to learn. Great videos, I've subscribed and hope one day you offer Electronics 101 courses with simple exercises to do... I'l get myself and my kids to watch every one of them, and then do all the 'things to build' excercises.
@@willybee3056 Not quite sure what you mean sorry. I think the reason for calling a hammer a 'Birmingham Screwdriver' was a derogatory thing back in the 1800's between the Black Country and Birmingham, suggesting that engineers from Birmingham were poorly trained and unprofessional, so they would use a hammer to put screws in, rather than a screwdriver. The Black Country was, and still is to some extent, very proud of its specialised engineering skills, whereas Birmingham was always regarded as a place of 'mass production', rightly or wrongly.
My dad used to refer to hammers as "American screwdrivers". I always assumed it was due to him serving on ships that were built by the Yanks during WW2
"I hope [the current's] not too high, because that's going to shorten the life of the lamp greatly," said Clive, contemplating the electrical innards of a lamp whose life he'd already rather abruptly curtailed using his magic wand.
@5:45 "i'm going to use pink wire to extend it because it makes it safer"? I always thought Plum coloured wire was safest? Learn something new everyday ;-) Love the humor Clive!
I nearly had a moment when you started waving your finger in the vicinity of that VERY Mains-referenced and nicely exposed capacitor, Mate! (around the 15:46 mark)!
You do seem to have a Affection to things that shine. Lighting of any flavor and types ? LOL I would like to see your take on the Carbon Arc Lamp ? LOL DIY type of coerse ! As a kid I built one using Battery Carbon Rods regulated by a salt water resistor. People came out of they're home watching me illuminate the clouds. Not quite the Bat Man thing but most cool to be sure.
Hey Clive, have you seen the FireGlow LED lanterns? Those seem to have the most realistic flame-looking LEDs that I've seen so far. Doesn't seem like they're that common on eBay, because those that are common have a very harsh flickering turning the LEDs instantly on and off, while the FireGlow LEDs smoothly fade in and out. There are some sellers that sell them from the US, I'll be sure to try one of those and make a video about it.
Hi You should look out for a cheap Variac , if they exist . I got my 2 cheap a very long time ago . I got a small 1A one but found that it was not quite enough so then I found a 2.5A . I have mounted them into old paint tins with meters and sockets . Alan
When I purchased my 2 variac's they were cheap --- but it was a very long time ago when the electronics magazines here in the UK were full of small ads from 'surplus' suppliers who sold them at a very low price because they were not new or cased . Alan
Is our house now out of date by having all the light fittings bayonet-style? Is it more usual to have screw fittings nowadays? I'll admit we haven't bought a lamp in ages, might take a look next time we're in a suitable shop…
I was just in Ireland and Scotland for holiday from the States. We experienced electric showers for the first time and I can’t figure out how they work and how we didn’t get shocked while using. Would love to see a video explaining them!
ruclips.net/video/cNjA0aee07k/видео.html ruclips.net/video/ZwuhFLsowRc/видео.html Here are links to shower teardown videos. One dangerous and one safe.
You sadly cannot do that... That will mess up the Multiplexing, and can even destroy the transistor array due the "shorts" which the capacitors presents that array when they are discharged. Been there, Done that, and End of Display unit for me after a few minutes.. I was lucky that I could re-order all the transistors, and remove the extra caps.
They use 110v in the bathroom because it is less dangerous than 220v full whack british and probably current limited too. In Canada before GFI fault circuits there used to be a small two prong plug instead. It would run 110V but with such low current it would be safer. Typically with "For Razors Only" embossed on the receptacle cover.
It might be an attempt to compensate for the poor power factor, maybe reduce interference slightly (not significant with these circuits anyway) or perhaps to reduce risk of mains borne spikes damaging the capacitor
3:05 - Can your camera (phone?) record at 25 fps, and / or can you control the shutter duration to make it a multiple of 50? That might eliminate most of the flicker, assuming the HOPI's update is based on mains frequency.
One of my hobbies is literally buying bulbs on eBay to find anything that looks great, has a neat warm white color and doesn't flicker. I also like to buy different electronics with different kinds of displays on them, LED, OLED and VFD for example. Not a cheap hobby, but not the most expensive!
Finding ambient light LEDs that don't flicker and with reasonable color spectrum is really hit or miss, even in the same brand, even same model number. I had Xanlite ones that were perfect, no PWM and the color was very close to incandescent; wanted to buy more of the exact same model, apparently they changed their circuit because the new ones do flicker.
Hey clive, noticed this for a while now, but if I recall correctly you're filming this with your phone right? It 'should' have a "anti-flicker" option somewhere, which you can set to Off, 50hz or 60hz, you could try that to see if it removes the flickering from the strobing LEDS and displays.
7:05 Clive shows that he should have been the one carrying the Ring to Mount Doom. He could have walked right down to the lava pool and made sure it REALLY sank!
If you just need to charge your phone, you don't even have to worry about it, most chargers are rated 100-240V, you just need a plug adaptor from Poundland.
Just as I was thinking in my head that it would probably work fine here in the US on 120V you also made that discovery. Being an unworldly American, I thought that the Edison base was specifically for 120V and that the 230V world used a different type of socket, am I wrong? In the residential side, Edison based sockets are about all there is for selection of lighting besides the small Edison sockets for chandeliers or garage florescent lighting that is now becoming LED technology.
Good to know about the use in 120VAC countries...gunna have to pick up some of these...I like the design :) PS> Would it be possible to add a second of those LED strings serial and just widen the spiral to accommodate 240VAC power?
FYI. google decided to advertise "grow lights' showing the product they are really meant for... California Light Products by name...weed has gone mainstream in the US...did not expect that...next ad was for outsourcing, for every high there is a low...so to speak....now to enjoy your video, the real reason for being here...
It makes me wonder if the lamp is actually intended for 120v rather than 240v, given they apparently are known for supplying the wrong items and all... :P
I have a REALLY weird led lamp that I'd like to send you. They were included in my ceiling fan, but don't seem to get along with the remote control module in the fan. When the lights are turned on, they strobe quite heavily. I popped one open, but I have no idea what's going on inside.
That's common with some LED lamps when used with electronic switching devices that either leak current when off or fail to latch with the low load current.
@@bigclivedotcom Well, the weird thing about these ones, is that there's no power supply. They look a bit like those driverless LEDs you tore down a while back.
Hi Big Clive, I just like to say I enjoyed your videos. I have a question about the batteries that you tested awhile ago, Do you know what happened to the Fusion Max endurance batteries? Poundland have stop selling them? And are you aware that Maplin has opened up their website again?. Thanks very much and keep up the good work. Alan
All that wanding made me note you have not done any of the gameshow type videos in a while (which resistor explodes first etc.). Any ideas for new games?
How many led lamps in Clive's house have a CliveCo brand adapter to limit current? Some bare wires and a couple of components makes everything better! And keeps people from bringing noisy kids and they little hands from coming over. BONUS!
Giz some of they Irn Bru jellies! I've got a big spool of pink wire at work. I never knew about it's additional safety features. I'll use it more often when dealing with higher voltages.
Might i suggest, that you fabricobble a base load of 1 or 2 watt (capacitive and/or resistive) to allow the hopi to test low power devices ? dummyload + to-be-tested device ?
Slightly off subject but I received an LED flashlight the other day and it runs on a 3000 mah 18650 battery and puts out an astonishing 4000 lumens this is amazing LED technology is going forward in leaps and bounds. I was melting Styrofoam cups with the light beam.
Clive, have you seen lock picking lawyer video 510? He mixes a pyrotechnic and uses it to blow open a padlock. He missed out all the best parts though, not showing us the preparation and then fluffing the filming of the explosion. Fancy doing it in a more Big Clive way?
If you already had the wire disconnected, you could have just measured the current with a regular meter. You know, just to be sure you're measuring the correct current. Anyway... About the device at 16:30, I figure it probably uses a switched mode power supply that runs on 100-250 VAC or so like most phone/laptops chargers etc. so that they can run in Europe and the US. I'm honestly really surprised anytime I come across a switched mode power supply that doesn't tolerate 100-250 volts since apart from marginal better efficiency and saving a few cents on a lower voltage capacitor etc. I really can't think of a good reason to limit the voltage range.
Clive, my friends have horrible shimmery capacitatively coupled led lights. I think they could do with a higher frequency, probably lower voltage supply to make them less flickery. Can you think of a ready way of accomplishing this? It could make a good channel project.
Aha! You use the same tools as we in Yorkshire. It's also known as:- A . . . . . technical tapper, Tyke's spanner, knocking stick, Edinburgh socket set, Manchester screwdriver, and a whole host of other things! Now then, do we suppose these lamps were engineered around 120V nominal, and at any other voltage you lose out? I mean, if it's designed for the USA/Canada market, and the makers said, effectively, "It also works at 240V (just no so long lived) so why bother to produce two variants, and by the time it's failed at 240V, they'll have lost the receipt anyway, so tough...!". . . . . All costed down to the cheapest price at the end of the day.
It's the Poundland LED lamp circuit with fewer LEDs. As supplied the LEDs are overdriven. It should be possible to cut the LED string in half (lose one LED) then connect the two strings of seven in parallel. That way the LEDs are operating at half the current and should last a lot longer.
By the looks of it they are very restricted by a fuse to only allow very low power devices. "They severely restrict power output using a fuse or modern GFCI device. UK sockets are supposed to limit output to just 200 mA, while other standards allow a range of 20 to 40 Watts" Sounds reasonable as they have been around for long before modern protection circuits were common.
Anyone know where one can buy the base of a bulb without the bulb? I am trying to find "blank" BA9s bayonet bulbs without the bulb. All the LED ones I can find are 6v or higher, and my project just needs a regular 3v LED. I figure I can make my own, but do I have to destroy a good bulb to do it? Ideas?

Why is the shaver socket in your bathroom a different voltage?
And what do you use a shaver for?
They use 110v in the bathroom because it is less dangerous than 220v full whack british and probably current limited too.
In Canada before GFI fault circuits there used to be a small two prong plug instead. It would run 110V but with such low current it would be safer. Typically with "For Razors Only" embossed on the receptacle cover.
Shaver sockets have an isolation transformer for safety, often tapped for both 120 and 240 volts.
What purpose does the inductor serve?
And is that the cause of the abysmal power factor?
It might be an attempt to compensate for the poor power factor, maybe reduce interference slightly (not significant with these circuits anyway) or perhaps to reduce risk of mains borne spikes damaging the capacitor

I can think of many things in this world that need Clive's magic box and wand.
I see the 680nF droppers in some of the cheap nightlights sold here in the US. It does seem a bit much. I usually go with 220-330 in my own bulbs.

Aha! You use the same tools as we in Yorkshire. It's also known as:- A . . . . . technical tapper, Tyke's spanner, knocking stick, Edinburgh socket set, Manchester screwdriver, and a whole host of other things!
Now then, do we suppose these lamps were engineered around 120V nominal, and at any other voltage you lose out? I mean, if it's designed for the USA/Canada market, and the makers said, effectively, "It also works at 240V (just no so long lived) so why bother to produce two variants, and by the time it's failed at 240V, they'll have lost the receipt anyway, so tough...!". . . . . All costed down to the cheapest price at the end of the day.
Love the magic wand :)
I think that Iron Bru is an acquired taste, I tried it for the first time a few months ago, I cannot explain the taste but it is very sweet!
What’s a shaver socket?
A socket for a shaver.
Wand of knowledge... Nice!
what's to say the LED's aren't more than just regular 20mA devices?
They look like standard 20mA devices being overdriven.
It's the Poundland LED lamp circuit with fewer LEDs.
As supplied the LEDs are overdriven. It should be possible to cut the LED string in half (lose one LED) then connect the two strings of seven in parallel. That way the
LEDs are operating at half the current and should last a lot longer.
I suddenly realise that I own a large collection of magic wants. Harry P. here I come!
Why do you have lower voltage in the bathroom?
Standard to use lower voltage in bathrooms here in Europe I guess.
Shaver socket, it’s usually 110/120v Sorry, don’t know why 🤔
By the looks of it they are very restricted by a fuse to only allow very low power devices.
"They severely restrict power output using a fuse or modern GFCI device. UK sockets are supposed to limit output to just 200 mA, while other standards allow a range of 20 to 40 Watts"
Sounds reasonable as they have been around for long before modern protection circuits were common.
Shaver sockets provide 220 AND 110.... and American/European compatible plug-holes so you can plug your shaver in no matter where you come from.
how about adding one more led in series?
I wonder if the 240V "version" was designed just by increasing the voltage rating of the capacitor and noting that it appears to work on 240V.
Sounds about right.

Anyone know where one can buy the base of a bulb without the bulb? I am trying to find "blank" BA9s bayonet bulbs without the bulb. All the LED ones I can find are 6v or higher, and my project just needs a regular 3v LED. I figure I can make my own, but do I have to destroy a good bulb to do it? Ideas?
if this was 1930's sure ;)
You never fail to entertain. I do see 1,000,000. Sorry, 1M. (Unless it is old electronics where 1M means 1K). (Mr Carlson's Lab, Supreme Vedolyzer).
