Revisiting an OLD project from 20 years ago - with schematic.

[@TiptreeJams]

Yes it was 'Prototype mains LED lights' on 23rd May 2022. But that said I love watching BigClive videos over and over again anyway.

[@HobbyHalloween]

I know that feeling. I had the same kind of shock when I looked at a date on a project and said that was 20 years ago!

[@SeanBZA]

Looked at one, and i made it in high school........

[@ryanroberts1104]

I can usually date mine by the soldering. It starts with wires twisted really really tight and progresses from there. :p

[@Mark1024MAK]

Oh, let me check a project I made after I started my first job, ah 1988! It’s a bench PSU that I still use. Only thing that I have replaced is one of the potentiometers. Although one corner pillar in the case is broken. All the parts came from Maplin by mail order.

[@gregorythomas333]

Revisiting old projects are always fun...not only for the nostalgia...but also remembering the way you were thinking at the time along with what was the technology available.

[@ffffffff-vv7yp]

This project keeps getting more and more well presented during every remake. It's noteworthy this was just as antiquated when the 2022 and 2016 versions went on air. Just think about the rate of technological progress going on about 15 years ago. Those were the times - yeah, I know other fields are changing really fast at the moment. I'm excited to see the 2030 version. Young tech geeks who were hardly born in 2016 will watch and be amazed.

[@ericthecyclist]

Reminds me of the LED oscilliscope I built 45 years ago from a diagram in Popular Electronics magazine. I had a 10x10 grid of leds soldered into perforated board with wires running both ways. It worked, but every so often, one of my solder connections would fail. I had to use it in a dim room to be able to see the red leds.

[@mistermeaargee2670]

I bought three rare and very expensive blue LEDs for the rear of a Melenium Falcon model I was building. Great effect with laser-etched 'hologram' foil behind them!

[@amorphuc]

Thanks Big Clive. Wild how time flies. It's sometimes really cool to look over past projects to see how you'd maybe change them today or appreciate the work you did.

[@RODALCO2007]

I like these simple designed led lamp circuits with no fuss. Great to dissipate the heat over multiple resistors scattered around the circuit. Nice perfectly aligned LED's.

[@OldNerdyMeathead]

Love this content. Going back to old projects with upgrades due to new tech on the market is awesome!

[@johnrehwinkel7241]

You mentioned wondering if things still get blocked by customs. SparkFun did have a little fracas a while back when they bought a batch of inexpensive multimeters from overseas and they were held at the border because the yellow/gray color scheme was trademarked by Fluke. A bunch of people were mad at Fluke, but they hadn't done anything, it was the customs agents that made the decision. Fluke was very nice about it, and gave SparkFun a batch of genuine Fluke gear to replace the impounded lot. I notice that some of those LEDs haven't failed entirely, they flicker some when power is first applied.

[@RaJ2986]

I been follwoing your site for about as long. Purchased a few of your RBG controllers and still using them to this day. Also still have quite a few of your highflux PCBs.

[@acmefixer1]

I had a conversation with another author of a project that applied rectified but unfiltered (not "smoothed") DC to some nonlinear devices like LEDs. He said it had to be multiplied by the cosine of the phase angle of the conduction. For a blue LED, it doesn't conduct until the voltage gets up to 3V. So if the AC across the LED is 6V peak, the LED is conducting current during the 3 to 6V part of the cycle. But I've forgotten the rest of the calculations involving the cosine, etc. I hope that was helpful. The greatly simplified solution is to connect an electrolytic capacitor across it and get straight DC, making it easy for the meter.

[@bigclivedotcom]

The blue LEDs start conducting and glowing at about 2.6V with increasing forward voltage as the current increases. That makes it a super-complicated voltage/current waveform.

[@erickvond6825]

I've been watching your videos for quite some time now and I've never seen these projects before.

[@mina47879]

Looks like you've covered them twice haha, the one that's been previously mentioned by someone else, and "Prototype LED modules from 2004. (with schematic)" back in 2016. They're still interesting tho, and i missed those previous two.

[@stephenmanning1553]

Showing us antiques that you made. Fantastic.

[@mikebond6328]

[@robertgaines-tulsa]

I don't remember you talking about this. It does take me back to when LED lights were still new and these janky lights were only available from China. I got into an LED lighting craze at that time. The dim, cold blue light and all the individual LEDs felt like lights you'd see in Star Wars. I eventually got sick of them and switched to warm white LED bulbs when you could finally get inexpensive ones at the store. Lately, I've switched to brighter daylight bulbs as they seem to help with my depression. They also make colors pop out better.

[@BromideBride]

Not just old school 2nd class leds that fail. I spent this morning swapping smd leds from one gu10 lamp to another based on the latter having just one short and one open circuit. The former had five blackened, Incinerated and several that look cooked. Annoyingly, the lamp works for a while then one string of 30 - half of the lamp, goes out until the power is turned off and on which restores it briefly. So I now have to find the leds that are going open circuit I guess. It has a cap, bridge, resistor driver board that was stuffed behind the non heatsink led circuit board leaving a brown burn mark. They weren't even cheap ones,just badly built for the throw away society. A few years ago I would have binned the pair of them but my new found knowledge from your channel & similar has caused me to start understanding these issues sufficiently to attempt a repair. Plus it saves me a morning of driving 30 miles, paying as much for parking as fuel to get there and hunting for a shop that sells replacement lamps or waiting five days for China or eight for British sellers to despatch and deliver some.

Blue LEDs were amazing when they hit the market. Remember when they'd stick a piercing blue indicator on every bloody thing.🫣

[@simont3686]

[@Poult100]

I think it still happens too much. Makes me realise the red LED has been under rated all this time.

[@simont3686]

@@Poult100 Yes. Red or amber are so pleasant to look at. They don't stress the eyes at all. Even green is better than blue. Blue is literally the worst color for indicators. But somehow the companies still equate the modern-ness of a product to the brightness of its blue LED.

[@tncorgi92]

I had a couple of external hard drive cases, the single blue LED power indicator was so bright you could read in a dark room with only that powered up. Must have been good quality though, I don't remember one ever failing on me.

You eventually release those panels with the Piranha LEDs. You kick started my love of RGB LEDS, Built them into the flood lights along with your controller and used them on my mobile discos for a while.

The Piranha panels were great at the time. A very affordable way to make an RGB floodlight.

Totally unrelated but the tiitle and thumbnail reminded me of it: I just bought a cheap nose trimmer that is said on the website to have a built-in LED but it's actually a tiny incandescent bulb ! And switching it on reminds me of my childhood's incandescent flashlights as well as of the era itself.

That's very retro. Probably an old design that hasn't changed.

[@cheyannei5983]

I know what you mean about being unable to find a video. I spent like two years on and off looking for a video that featured a little side-firing 18650 light that almost looked like a mini fluorescent tube. By the time I found it, the factory that had made them in that size ceased production. I ended up finding an Energizer light that was the same size and roughly fit the bill. Speaking of, I bought a spare of that Energizer to send over, but it seems almost impossible to disassemble.

[@DrHarryT]

With 60 LED's in series here in the US you can run them with a rectifier and cap directly off of the 120VAC mains.

[@i_am_aladeen]

Clive talking about "having to cut" some plastic, while wearing a bandaid 😁

[@HardwareHarry]

Hi Clive, thanks for another interesting video. If you made the same project today, would you use a death beam capacitor to smooth the output of the full bridge rectifier? Smoothing seems ubiquitous in designs now, I guess they would eliminate any visible flicker, and give the LEDs a much smoother supply (I wonder if LEDs using smoothed power would last longer and fail later than the identical build without the capacitors)?

[@bigclivedotcom]

I might, but that does increase the voltage to the sinewave peak. So it would require more LEDs.

[@michaelmoorrees3585]

Looking at old projects, I'm looking at my old LED digital clock. Its big ! 6" (15cm) tall digits made up of 28 discrete 5mm red LEDs per digit. Six digits. TTL logic. Uses 15W, and a linear power supply. Mechanical hourly chime. Dim old red LEDs, as it was made in 1982, when I was still in college. All LEDs still working. Replaced a power supply cap, when it was only 10 years old, and 2 7447s over the decades. Blew a lot of dust out of it, as its vented.

While watching this video, Big Clive, I noticed that there were 115 comments. Why is this significant? ... It's significant because I see the number 115 literally everywhere, all the time! What's special about the number 115? ... It was the house where I grew up from 1968, aged 6, and it's the house that my late parents left to me, 20 months ago.

[@markfergerson2145]

I think you did do a video on those lights, unless you do a lot of projects with those serpentine tracks. But that’s okay, looking to see how a project has aged (or not) over a span like that is a Good Thing. Honestly I’m surprised that more of the green LEDs didn’t die or change color. You mentioned that you think heat might be the cause- letting it warm up for an hour or so and looking at it with an inexpensive thermal camera would be instructive. Would have been nice to have those twenty years ago, no?

Check there's no battery tab to pull out and that the switch (usually hidden under the lens) is in the on position. They can also be a bit sensitive to ambient light sources and stay off if you have another light nearby.

[@twocvbloke]

I think you have shown these (or stuff similar to them) before, but it's probably long enough ago that it's forgiven to see them again, reminds me of when I turned a dead CFL (Philips or GE where you could unscrew the bulb that covered the CFL) into a 12v LED light, except I did it poorly, assuming the LED were all 3v and "12v" was actually 12v, and they burned out eventually, some rather smokily... :P

[@CrazyOregonBeaver]

About 30 years ago I built one out of surplus green LEDs from Tektronics. Here in the U.S with a 120 volts and about a 170 volts peak. I use a group in series of 6 X 12 or 72 LEDs, and in both directions for a total of 144. Straight into the wall. It has been running all that time with no failures. I'm just waiting for one go, and then it's all over with. I think, or maybe just half of the panel. 😂

[@bigclivedotcom]

I think the foreverbright LED strings ran directly across the power too.

[@DelticEngine]

Curious coincidence that 5.4 divided by 1.414 (like you would to determine RMS from Peak voltage) equals 3.8?

[@bikkiikun]

What would be the pros and cons of adding a "smoothing" capacitor to your lamp? I'm guessing, you would need to handle peak-voltage, instead of RMS and I also guess it would ruin the powerfactor. But is there anything else against or in favour of a cap?

[@bigclivedotcom]

It would be a good improvement, but would require a lot more LEDs to keep the resistor dissipation down.

Blue was... *wow!* White was a little unimpressive, as it had the infamous "Cree Rainbow", especially noticeable when you'd hold one close to a white card or wall. Blue center and yellow periphery.
