Props was my first thought. I recall back when Star Trek TNG tricorders were the hot thing and folks went nuts trying to duplicate all of the blinky light effects. Now you can do it with a COB with a built in micro.
I think the lower LED count at the end more give the impression of variable speed, and that last bit where the drop hangs on for a sec before shedding off (drip wise).
There must be more to it! It looks like individual LEDs, not LED groups, are switched. Clive, are you sure you didn’t miss anything? Can you do a slow motion recording of it? Then we can see whether it’s individual LEDs or LED groups that get turned on and off
@kimchristensen2175 But even then, with pwm, how does the controller address individual LEDs, which it obviously does? Or is there some logic in the LED groups, hidden somewhere? If four are connected together with just one pin on the controller... How does it create a fading light effect from one side to the other, like a larson scanner? Clive must have overlooked something.
@@helmutheller1538It's using anti-aliasing. Anti-aliasing can make text much more readable even on a low resolution screen. Same principle here. Note that, even if this is not the case here, it is possible to individually address up to 30 LEDs with 6 inputs thanks to the "Charliplexing" technique.
Those are cute little LEDs. Thank you for showing them. I have seen those used on some car alarm systems here in the US, to make it very obvious the vehicle is armed at night. Personally, a simple single blinking red LED is more than sufficient in my vehicles.
Very cool little objects, I can definitely see some uses for them and pretty cheap for what you get. I was thinking maybe in a computer case, but that might just be me.
One area of my city used dangling string light versions of this same effect as part of their outdoor Christmas lighting displays this year. I was speculating that it might have been charlieplexing the LEDs. This is an even simpler method than I imagined.
Yeah they had those large ones in my city too. I thought Charlieplexing initially. It would actually be nice to have a Charlieplexed version, then they could drip or maybe sparkle instead as each of the 30 LEDs could be independent with 6 GPIOs.

Oh, these have a wonderful dropping effect. I like them a lot, in fact, I can think of a few modelling projects out of them. Edit: Clive, I saw another listing for these. If you keep the neg attached to the power. Then add the pos by tapping it on the pos tab once each time. The LEDs will flash in 5 different patterns, one tap per flashing sequence, eg, like the KITT car L-R &R-L red strobe effect. This makes them even better for a visual affect.
I made a bunch of these at 3x the length with an AVR ATTINY some years ago and 3d printed several spiral icicles variants in clear PETG. Came out very nice.
Beautiful, thinking they'd be excellent for my taillight on a custom bike, and lots of other things. Well done Clive, the best little light show yet. Thank you 😊 ✌💚🇬🇧
My neighbor's got a bunch of these but they are larger, individual stakes you put in the ground and they charge from a solar cell. He's got them all along his driveway and the effect at night is very nice. (His are blue also)
I build miniatures for all kinds of stuff. but right now this has me thinking about using something like this for a landing lights on a landing pad. arranged so the light all cascades towards a center point would look epic.
They seem to be selling these with an attached battery pack for rear bike lights. It's exactly the same PCB with the same IC soldered into the little LiPo pack.
That's so cool, I still remember the first time I saw the giant "snowfall" light tubes in a boutique Christmas store (for hundreds of dollars) as a kid. Now we've got these 😀.
@@PinePondCTDevilsHopyard-fy3hj Not so long ago I decided to compile a playlist of music I had had as a child. Done that and had listened to that all day. But something was missing, could not understand what... _Spinning reels!_
Yep, I have seen the falling snow effest many times when going out during the Christmas season during the last decade if not even a bit more. Although it was always longer and wider lights than the tiny ones you just shown here.
I'm very surprised at how well the groups LEDs simulate a finer grained meteor effect. Watching them I would have expected single LED resolution, but stepping through the video seems to show changes only in larger groups.
We have an art/fashion show thing (World of Wearable Arts) here in Wellington I was involved in a few years ago and they had full sized ones of these in the auditorium as part of the show. It's a really nice effect.
Very nice! Thanks for another great video. When you said “About 20 LEDs…”, I immediately thought, “Oh cool! a 5 pin Charlie-plex”, so I was a little saddened to see it was just four discrete channels. Could have been random access! :D
These are great, I didn't see any meteor lights this Xmas in any of my local towns - seems to have gone out of fashion? Don't know why - I still like them.
Oooh...love to see a project where you built them into a spiral or circle or something cool...is that a possibility? Thanks again for the video and as usual the very easy to understand explanations on what is happening with all those little electrons! Love your videos and commentary!! looking forward to the next!
Same as them flame LED's you showed months ago.....I ordered those a month ago, because they dropped significantly in price . And ordered a bunch of these with them.....
I wonder how many LEDs can be run on each leg without damaging the chip. I could see this chip being useful for controlling direction pointers, particularly if it can handle considerably more current than the stated 20mA. If not, it could still be used to drive a mosfet on each leg and that would have the advantage of being able to switch higher voltages too, perhaps 3 LEDs in series to run off a 12v supply.
Ah I’ve recently seen these in a video for a "Bike light" and I said to my self that these have to be pre made modules xD. I have to say they’re pretty cool. Probably gonna buy some.
Just bought a few, they look very nice 2x👍 My Patreon email was missing the link to this but someone posted it as a reply for me. So not sure why it was missing. 🤷♂ Thanks Clive great video 2x👍
As a kid, I used to lie on my back out on a hill in the countryside for hours at night, watching those little meteor lights flash through the sky. They don't look so exciting any more now that I'm older...
i love the effect, really very nice :) .It would be desireable for two or maybe three enhancements; 1. speed control 2. dim control and ..in a dream world perhaps being able to reverse the pattern so that they could be placed 'upside'down'.
If you want to smooth out the current reading, go power-source --> meter --> 470uF cap --> doodad. Charge the cap and measure if there's any significant leakage current to subtract out later. Let the doodad draw off the cap. It supplies current to the doodad even with spikes, and the meter reads smoothed-out current readings. I had to do that for a "beacon" light, nothing, nothing, nothing, nothing, huge current spike, nothing, nothing, nothing, etc. Only it needed something like a 20,000uF soup-can of a capacitor.
Dunno whether the pin out the Atiny85 would work but if it did you can easily see the sequence of lighting and dimming they have used by using the frame advance buttons on your keyboard '' and relatively easy to code, I don't know Python but very simple in 'C'. Went an got some of these right away ! (a first for me) so let playtime begin....cheers !
In Tunbridge Wells last Christmas there was LEDs Christmas lights strung up in the trees and they were doing the same thing has your LEDs lights but they were about 30cm long and I wonder how they work and now I know. Thanks Clive
I designed up a heart a bit like this last year and a circle like that back in around 1996 before some dude at Maxam got the technique known as charlieplexing. However my ones are wired to the spare pins for individual LED control. The one you've revealed is not so sophisticated.
I can usually resist, but these are too good and I caved. I just ordered a pack of 10 of each color! They're going to look great on my "mini christmas tree" that I decorate with all components de soldered from circuit boards. The scale should be about right too! The lights are all hand assembled 5mm LEDs, and the topper is an old Pentium MMX 200MHz surrounded by yellow LEDs - it's a very "clive-esque" tree in many ways
It's surprising that the human eye doesn't notice that the LEDs are being turned on in blocks. I initially assumed they were doing cunning things with the five IO (Charlieplexing or similar) to drive each LED separately but no, just relying on the failings of the human Mk 1 eyeball to perceive smooth movement.
Clive, will these run off of 3x NiMH cells without regulation? Might work nicely for garden illumination, fill some of the solar garden lights with clusters of meteor lights, the average power looks to be low enough that they'd probably last a good bit through the night.
Ooh, lightsabres for a flea circus!
My thoughts exactly 🤣
Brings to mind ( Flea Circus (1950) on youtube!
Perfect size for LEGO figurines 😂😂
Rgb rectal thermometers
Ha ha :-)
I've used them in props, they run for a whole day on a 2032 battery or 2 in series on 5v for a lower brightness. really useful for confined space.
Props was my first thought. I recall back when Star Trek TNG tricorders were the hot thing and folks went nuts trying to duplicate all of the blinky light effects. Now you can do it with a COB with a built in micro.

Earrings necklace hat brim spiked Mohawk hair etc. Thinking party club cosplay. Really cool ornament. Love the 3V.
It still amazes me how 4 'channels' appear to flow so perfectly...
It's six, but it is unusually smooth.
There must be more to it! It looks like individual LEDs, not LED groups, are switched. Clive, are you sure you didn’t miss anything? Can you do a slow motion recording of it? Then we can see whether it’s individual LEDs or LED groups that get turned on and off
They might PWM them so that one fades out as the other fades in which would make it look smoother.

For parties, yes.
Outdoors, no. Just another unwanted distraction.
There are also variants with multiple patterns, triggered by shortly cutting the power to select the next pattern (upto 6 patterns in total)
Those are cute little LEDs. Thank you for showing them. I have seen those used on some car alarm systems here in the US, to make it very obvious the vehicle is armed at night. Personally, a simple single blinking red LED is more than sufficient in my vehicles.
I've had my eye on these for a while to do a retro future-esque lights on a retro car project
These are cool. Now I want a bag of each colour.
Lighting has become so cool and hackable. Very interesting Clive.
Thanks Big Clive. Those are supper cool.
These were a good find Clive. I like these.
Oh darn you Clive... you got me. I ordered three different colours and then got entranced by all the other LED's on AliExpress.
Mine just arrived and they actually include a surface mount decoupling capacity on the pads below the IC.
Very cool little objects, I can definitely see some uses for them and pretty cheap for what you get. I was thinking maybe in a computer case, but that might just be me.
These would probably work well as pilot/indicator lights showing that the operator needs to do something left or right. Or in an arcade machine.

Many of the longer ones do Charlieplex the LEDs.
It was one of those that killed the LED dinosaurs.

At 230 volts, that's 4.6 jiggawatts!

Very cool little lights. I may have to order some too.
The band gap for blue leds is 2.6 volts so that's amazing it glows on such low voltage.
They would look really cool on city Christmas trees.

I love them, so many uses
Those are good. If they made even more-near UV leds in that form it would be even better.

You should make a panel with them, similar to the supercomputers but lines instead of dots. Maybe put every other one going the opposite direction.

A got some the other week...some of them had an extra component and it didn't matter which colour they were.
If they had a little capacitor next to the chip try pulsing power off to them briefly and they may change the effect.
