"No No - I'm talking absolute crap" Such honesty is very refreshing.

After also watching Julian's video, I thought I would take one apart. Just like you I did exactly the same thing. Also took me 20 mins or so to work out what was going on. You could imagine the pain I was going through, screaming at you all the way from New Zealand with the problem, the 20 minuets seamed more like hours!! So pleased it also took YOU the same time to work it out!! It first I thought they were the series type that needed 70+ volts per strip to light and used a boost converter. After I got to 100 volts I thought I better take another look!!

Even when things don't quite go to plan, there's always a great learning experience. This one was "when things don't work they are probably broken". (anyhow, I too was waiting for you to over crank the voltage and blow up one or the other LED upon reading "disaster", lol!)

Good one, Clive. I'm so glad to see this sort of thing happen to someone else besides me. That scale of manufacturing is mind-boggling. (to small minds like mine, at least)

I ditched all of my cheapie M830Bs after they wasted hours and caused days worth of grief. Out of four meters (which looked similar outside but had very different internal PCBs) three had dry solder joints in the probe sockets that weren't immediately noticeable. Readings fluctuated wildly depending on the temperature, current, and if the leads were nudged slightly. Resoldering helped but cheap plating on the sockets meant readings changed if you rotated the leads. Two had issues where tapping the range wheel altered readings as you found at 6:10. One day I was nearly tearing my hair out diagnosing a circuit where the same wire measured as 12V in the engine bay but only 2V inside my car. The LCD wasn't tight against the circuit board, and the rise in temperature inside the hot car made the 1 disappear. It was reading 12V all along. Tightening the screws holding the LCD in place helped but soon stripped threads so the problem returned and ruined another day. One of them changed readings if you squeezed the case. Never did figure that one out, but probably a combination of everything above. The fourth one seemed the best of the lot but the range pointer was ambiguous. It had a very defined arrow which at first glance appeared to point to the selected range. But it also had a small dimple (like your meter) at the other end which was the REAL indicator, not easily visible in dim light. Forgot about the weird knob one day, tried measuring battery voltage in current mode and BANG... blew the arse out of it and burnt my hand. I made the decision to scrap them all, saving myself a lot of grief. Time and sanity scarce these days and I'd rather waste neither! I've since bought four small Aneng multimeters to inhabit my scattered toolboxes, which seem far better in every way than the M830Bs. They even have buzzers, backlights and temperature probes.

Before I forget, I should mention that most of my store-bought alligator clip jumper leads were poorly crimped. Some weren't cheap either, it didn't just affect the bargain basement leads. Most had wires that were too thin to reliably crimp in the alligator clips, so to "solve" this issue the manufacturers simply folded the wire back over the insulation and crimped the insulation in with the wire. I discovered this when some wires fell out of the clips while measuring higher currents than usual. The high current, high resistance connection softened the insulation causing the wire to slide out of the clip. After that incident, spent a few hours repairing or replacing dodgy crimps and wires on every lead I could find.

Microwave Dave - for this very reason, I only use test leads with either 4mm plugs and then fit a croc clip that has a 4mm integrated socket, or I make my own leads up and solder croc clips on myself. And yes, one of the problems with cheap multimeters is the unreliability of the contacts in the range selector. This is nothing new, it also affected the cheap moving coil designs available in the past as well. And almost certainly still affects any current cheap moving coil designs. The lack of quality on the 4mm sockets, or other smaller sized connectors is also annoying. For all these reasons, I restrict the usage of the cheap meters that I have to use on circuits operating at no more than 20V. If I get a result/reading that I don’t expect, I double check by using a much better multimeter in parallel 😉.

I tried to build a dc-dc converter very similar to this one the other week.. It went about as well as this video! Although mine was a Linear Technology 1613 SOT23-sized device and seemed to demand microscopic positioning of explicitly SMT support components. It did *not* like strip-board and a DIL-converter one little bit! I _was_ planning to try again with a much more spatially-forgiving design based around a micro controller to provide the pulse which I found on some German fellow's website, but... A couple of moderately expensive failures, one after the other in quick succession has really taken the electronics enthusiasm out of my sails. Maybe I'll try again post-Yule.

I love the description and watching it after.. Yes this is like life.. nothing is as it seems.

I ordered 6 of the clear (glass) globe filament-type 120V lamps for a dining-room fixture. 2 of the lot didn't survive shipping, with the LED bars rattling loose inside the glass. Not a big thing, as the remaining 4 filled the fixture and have been in service for almost 5 years now.

Here in the states, the 12 volt bulbs are used for emergency lighting. The circuit is wired to a 12 volt battery, and automatically come on during a power outage. I always keep a spare bulb on hand, because they all have to work to pass the fire dept inspection. A LED bulb would pull less amps and provide light for a longer period of time

Good troubleshooting episode.

Great save! Always wanted to know what was in these bad boys.

Clive, screwing up is the best way to learn.

Great video made even better with a reference to the fantastic Eric O at South Main Auto's

Thanks so much for this video! We've ALL had those days where one little thing seems to be completely halting the whole project until we figure out that tiny detail (like bad solder joints). To all the people thinking "Well, that's why you should be more careful!", half of tinkering with things is going to involve somehow forcing your way into something, be it physically or digitally, so that's not really an option all the time. (Although I would have just taken a soldering iron to the ends of those strips and tried to resolder them at that point, maybe add a touch of flux first to re-bind them - or did you try that to no avail? I uh... I'm clumsy, so I end up doing patch-repairs like that at times. *cough*)

Home Depot in the States is selling "EcoSmart Clear Filament Vintage Style LED Light Bulb" in clear and frosted glass but cram all the capacitors and resistors in the space of the Edison screw and between the screw and the capacitors is a layer of plastic. The result is that they get very very hot and die after only a few months/weeks of use. When the first start to die they flicker within the first ten minutes of being turned on for a couple weeks and then one day they don't turn on. I took a couple of failed ones apart and all of them reeked and the capacitors were bulging; one had electrolytic all over inside.

EpicLPer If you like disasters, check out Electroboom.

The bulb is shaped so because it's made to look like an Edison bulb. Traditional Edison bulbs have filaments in various shapes emitting a warm orange glow, but they're one of the most inefficient types out there. The bulb you're looking at appears to be an LED version of the Edison bulb, which should solve it's only drawback.

Disaster! This must be one good smokey vid!

I think these lamps are ideal in a camping environment, you can use them even with a half dead battery without turning the engine on.

that was a sudden pry and many things can happen... it happens ... Or prying something and cutting wires with pry tool. The final result is good, trace the problem, and keep going

That electrolytic capacitor is most likely the input capacitor. I had a bunch of those drivers in the 1W version, which can drive more LED's in series. The magic smoke comes out though when driving 2 LED's in series while lowering the input voltage below 8 to10V. These drivers work best between 12 and 14 V.

You really need a USB microscope camera setup... A SUPER tight zoom would be great for some of these... Thanks for the great learning content!

So it consumes more wattage when you lowered the voltage going in, is it possible to make it more efficient when exceeding 12 volts input?

That bulb is very deceptively called an LED (light emitting diode). There isn't anything diodec about it The emitting filament has no diode effect. The diode he mentioned in the circuit board he pulled from the base If you removed the plastic casing from around the internal filament will emit a very bright light...that would be a true light emitting diode. Those crazy readings from the FILAMENT is an incandescent effect ...not a diode at all! Bravo! The technician in this film has got it! What it is actually named is a "Light Emitting Wafer" with a filament core. Only about half as efficient as a true LED bulb.

It's worth noting that since this is a boost circuit, the output voltage can't go lower than the input voltage. So if you try to supply over the combined forward voltage of the LEDs, there's no current limiting!

I guessed a bulb or connection broke when it snapped apart and I wasn't disappointed lol!
