Really, you don't even need to mess with some tricky two-wire protocol, you could just stick a little microcontroller onto the bottom of the rotating shaft too and program it to do whatever you wanted (such as driving multi-wire LED strips too).. There's plenty of space there for extra electronics on the rotating part.
@@foogod4237 I meant the USB powered self controlled lights he has reviewed in the past. Would just need to cut the wires and solder them on 👍 they are wide angle LEDs though, so might not work well, replacing the existing LEDs with auto colour changing (not diffused) might work better!
@@foogod4237Instantly I can think of so many things you could do with that. Some 3D printed parts and some WS2812 strips and a generic controller unit with remote and now you got some fully controllable RGB effects.
@@foogod4237 one could. but tbh more and more i think MCUs are 'cheating'. it seems people think 'sod learning things about electronics, i'll just buy some arduinos!'. i often see on arduino fora people asking 'what is a pull-down resistor', or similarly obvious questions. MCU are cool, in their place, which i think is after learning about _real_ electronics for a few years. however i am a miserable old bastard. so probably wrong!
My OCD is playing up: the motor is connected to "BAT", the power supply (which is not a "4xAA" battery box as indicated on the PCB) is connected to "MOT". 😋
I think this would be even better if each LED cycled among different colors, either coordinated, randomly, or whatever. As-is, it's nice but the identical color star always drives across its same horizontal band.
Swapping the fixed colour LEDs for colour changing ones could give the effect you are looking for. A mixture of slow and fast ones would give the appearance of randomness as they rotate around the shaft. Perhaps Clive will "enhance" this one.
Two of the slow changing coloured LED's can be put in parallel, and then you can make strings of these in series. I found that 7 series sets of 2 parallel gives the best effect, but then sadly the supply is around 22 Volt, a bit unpractical. The individual LED's all have ever changing currents, from 1 mA to 10mA , and the frequency is slightly different per LED, so ever one in influencing every other.
I wonder what it would look like if you just used the outer pyramid structure and installed inside addressable WS2812B leds with somethign like an ESP-32 development board running WLED, so the leds were static but the effects using WLED (or even xlights, I guess) would provide the animation? I expect BC to complete this project by Christmas Day, ready for the great reveal!! Actually, I think my local garden centre in Addlestone has these in its Christmas section, so they'll be half price or less in the New Year!!
Okay, this is more complex than I would have expected. I would have thought that the lamps would be stationary and only a cylinder with a textured foil would be rotated.
That exact contact method is used in an old Tandberg tape recorder I've just restored for the record/playback switch, where a strip of double sided PCB is used with a couple of sets of those springy contacts either side held with a plastic 'sled' via links to the rec/play select lever. It's 55 years old and the contacts are still perfect!
Almost all AV equipment has one or more rotary switches that are based on this principle at least if its old enough to not use rotary encoders. My Danelctro guitar has suc a rotary switch to becaose it has more pickup setting than a toggle/ blade pickup selector could accommodate.Your car aslo has a clockspring in the steering wheel which is simular
Also used in electric car power steering systems,works great till the copper tarnishes and or sometimes when the weather's really cold and your steering goes notchy, im talking 2010 by the way not 2023 as they might now use something better like bamboo😅

I've got three of these, different sizes 8,12, and 16", different colors red, white and green...glass prisms...they're Christmas trees. Similar type of mechanics I think, haven't taken apart because they're kinda old and work on 120v w/incandescent bulbs. Belonged to my mother back in the day...1950/60's I'd say.
That same motor/shaft/ring setup was used in a couple of those 'fireplace' heaters. Cat/Dog hair binds up the blowers in those and i tend to scrap a couple every year.
Thanks a lot Clive. One another puspose for using the "rotating contact" method could be for making a rotating POV device. Many POV DIY videos show a battery mounted on the rotating part itself, which seems a bit cumbersome. Using a slip ring may also help, but may be a bit expensive.
Says 4xAA on the circuit board. There was or probably is a battery powered version but I'm not a fan of Alkaline powered stuff and NiMh is often too dark for the LEDs. It's just more interesting to know it can also handle 6 Volts.
2xNiMH is obviously not going to work with LEDs, 3x just about works but is a little on the edge, 4x is going to work absolutely no problem. Alkaline cells don't deliver much more voltage than NiMH over most of their life, they start above 1.5V but as they discharge, the voltage drops, terminating at right about 1V. While NiMH stay at right around 1.25V for almost the entire length of their discharge cycle. This is at low currents, at higher currents both types suffer some voltage depression, tends to be more pronounced in alkaline. So if NiMH were too dark, alkaline would have also been too dark throughout most of the cell life.
@@SianaGearz Most LED gadgets use just two cells, which makes it impossible to use with rechargables other than protected buck converted Lithium 1.5V cells.
I wonder what kind of grease that is. I’ve seen some labeled as “dielectric” grease, but not sure that’s what this is. In this use case, the grease has to lubricate, but not conduct so as to not short out the rings, but also has to not prevent electrical contact between the wipers and the rings.
Rattling nuts, shaft, screw, rounded end, good solid, splashed bench, big reveal and slipring all in one video, people would pay good money for this commentary 🤣
Replace the LEDs with slow colour changing ones and it'd change its' appearance even more, or just stick in LEDs of the same colour to make it suit where it'll live colour-wise... :)
That's a kinda neat cost-reduced slip ring. But not reduced so far that it's bare wire jammed up against the ring, they at least are using some cheap springs. I, too, wonder about the lifespan of such a thing, but they've at least put a tiny bit of thought into keeping it from wearing out in a couple weeks' use...
There is 4xAA written on the PCB so I assume there is also a battery powered version of it. And it surely will run of 5V USB then. Options for modifications.
This kind of slip ring contact made with a PCB is extensively used on electromechanical pinball/arcade machines and jukeboxes. You have a nice low voltage even higher quality gold plated one here.
I’ve been thinking of ways to recreate the eye of sauron. This motor combination used similar to the flame effect you did a while back might be the ticket.
Some years ago I designed some kit that was fitted on a rotating head which was fed power and data via slip rings... proofing the rs422/485 against the transients was ”interesting"
I was a bit puzzled about the grease - it appears to be present not only on the gold tracks but also between them. If the grease is electrically conductive, would it not short the tracks? If the grease is not conductive, how does it help maintain a good connection between the tracks and the pickup contacts?
Neat. Not familiar with electronics in rotation, so forgive my ignorance. Could ground be wired to the motor shaft? That way you could have 2 signals through the pads, with the shaft for ground.
did anyone notice that the moter was connected to bat and the power was in the mot conector so just wondering can it be modified to be rechargeable with batteries or even solar powered for outdoor use if made wether resistant
i guessed how this worked as soon as i saw it moving and was not disappointed ! lovely simple mechanism with diffraction lenses and a rotating pillar of lights :) i also like the simplicity of the pcb slip ring, although i doubt it'll last as long as more expensive purpose-built parts even with all of that grease. they should sell this as a beginner kit for children, it's very fun
would be nice if they made one with 5 of these and an pentagram center for a 5 pointed Christmas tree topper star the middle part could use a PCB with a buch or LED's that cycle arounf to creathe effect they are moving but it doenslt look like it is that bright though
The PCB has printed on it "4 x AA" ... does that mean that it was originally intended to be powered by four AA batteries? One of the connection points is even labeled "Bat."
What's more neat, from an economical perspective is the fact they're using triangular panels, so they can batch out a bunch of these from square stock with little in the way of scrap save for the half-panels they can't use in this application.
Mosk likely it is not. Most electrical greases aren't, if conductive it would cause resistive heating or a short between the traces. The pressure and movement of the sliding contacts will displace it enough to make a good connection.
Being a wedge shape, I now want to see if you could put enough of these together and make a full circle of them 🙈 Interesting effect, it's a shame nobody makes custom diffraction gratings! Be fun to add your own colours too, or hundreds of them 😅 I'd almost buy one now... What are they called?
This is like me, breathtakingly simple and it only takes one screw loose to fall apart. This was very well timed, I was just looking at slip ring designs! I wonder if there's a design that would be reliable and long lasting at high RPM 🤔
I wonder if you cut the ties nearer the top and splayed out the lights more like they are at the bottom if you'd get a better effect up the top... They're all so bunched together.
Happy Christmas Clive. For some reason having seen how simple it was for some obscure reason I thought it might be a tenner or so. Unfortunately far more £, not your fault. Have a good new year, will the carbonated soda Syphon be in use ?
i saw someone on YouuTube use this special paper once that goes on the bed of a 3D printer and it makes a pattern he printed a unicorn out of white PLA and whe he took it off the bed with the special paper it imprinted this pattern in it that mad eit look like an opal and it reflected all different colors, I wonder if you used one of those with clear/natural PLA if it would make something linke this material
Would there be any limtations (signal latency issues) by using this slip-ring princple for a 3rd additional ring for data xfer? Maybe drive a pixel strip (etc), or would it be easier to just mount the uP on the rotating shaft?
Can we see more of the 3v adapter next time? I don't remember ever seeing anything like that before. I'm in the USA. Is that kind of a common thing in the UK? Like the way 5v adapters are everywhere here?
@@bigclivedotcomyes: a 3V adaptor makes sense if you're feeding a strong of LEDs mounted in parallel. A 5V adaptor would waste a lot more power heating the current limiting resistor.
You could REALLY easily mod this to be programmable and ludicrously overkill. If you attach a little microcontroller onto the raised platform and just tap off the exposed connections, you could replace the string of lights with proper RGB tape with the MCU just taped to the top of the platform, meaning no signal integrity issues with the PWM signal as it's all up on the spindle already. The Seeeduino Xiao or Adafruit QtPy would be perfect for this. Hell, if you wanted to, you could even get a little capacitive touch sensor and connect it to the metal frame for touch control. This is a delight and I want 10 of them.
It would be interesting to know the origin of the design as like the first guy said they only appear on English websites and despite my best efforts, I can’t find it on AliExpress. It makes me think that the original design didn’t come from China , and it’s such a boutique effect no or few other Chinese companies can see the value in making them.
Unless you're in a property that hasn't been required since the mid 1950's. In which case be careful of the wiring as it's likely to be using cloth/rubber insulation that has passed its safe working life. The previous plugs had round pins and came in 3 sizes (for max current of 2- 5- and 15-amp). You still sometimes see the tiny round pin 2A sockets in use where a lamp is plugged in to a lighting circuit, but even those are rare now. Notice to that every outlet is supposed to be able to deliver 13A, so long as you don't bust the limit for the ring, which is typically 50A. And that's why every plug has it's own fuse which is supposed to be chosen appropriately for the appliance.
Rad. I need about 5 of those for my Fortress of Solitude crystal altar. Also, because a human had to put the LEDs on the post and shape them every effect will be different in each unit. Psychedelic effects will ALWAYS rule in Analog World! How much RazzPiDuino coding would be required to reproduce that effect in Digi-land?
That slip-ring system is pretty nifty! I suspect a similar technology might be in the less expensive slip-ring modules you can get from the "usual places", although I'd be a bit wary about the "claimed" 15A ratings. I've used a cheap slipring system on our solar light house model, and that's still very much going after 10 years' use (helped by occasional contact lubricant application).
Ooooh thats nice. I might have to get one. very interesting effect. 2x👍 you could make your very own police car blue light its a bit slow but still if it get people out the way. Im joking of course can you imagine how happy the rozzers would be pulling Ralph over with a custom in the back. 🤣🤣🤣🤣

I wonder if it goes under a different branding elsewhere in the world.
It would be interesting to know the origin of the design as like the first guy said they only appear on English websites and despite my best efforts, I can’t find it on AliExpress.
It makes me think that the original design didn’t come from China , and it’s such a boutique effect no or few other Chinese companies can see the value in making them.
Are the plugs all the same in the UK and other surrounding/close islands?
Generally, yes. I was in Dublin and Isle of Man (where Clive lives, met him in person, he's a wonderful chap) and the outlets were the same.
Unless you're in a property that hasn't been required since the mid 1950's. In which case be careful of the wiring as it's likely to be using cloth/rubber insulation that has passed its safe working life.
The previous plugs had round pins and came in 3 sizes (for max current of 2- 5- and 15-amp).
You still sometimes see the tiny round pin 2A sockets in use where a lamp is plugged in to a lighting circuit, but even those are rare now.
Notice to that every outlet is supposed to be able to deliver 13A, so long as you don't bust the limit for the ring, which is typically 50A. And that's why every plug has it's own fuse which is supposed to be chosen appropriately for the appliance.
Rad. I need about 5 of those for my Fortress of Solitude crystal altar.
Also, because a human had to put the LEDs on the post and shape them every effect will be different in each unit. Psychedelic effects will ALWAYS rule in Analog World! How much RazzPiDuino coding would be required to reproduce that effect in Digi-land?
why is motorb connected to BAC connector and power is connected to MOT
They're in parallel. Probably for connector position convenience.
Everything Old is New again !
Like the Motor, Gears, and Slip Rings. That is 1940's 50's tech'.
Yes it is. This would have been done with little tungsten bulbs back then.
Happy Christmas Clive, is that diffuser cloth available to buy. What do I search for? thank you.
I've not found it yet, but it could be buried in amongst the many craft holographic and prismatic materials on eBay.
Neat indeed !
That slip-ring system is pretty nifty! I suspect a similar technology might be in the less expensive slip-ring modules you can get from the "usual places", although I'd be a bit wary about the "claimed" 15A ratings. I've used a cheap slipring system on our solar light house model, and that's still very much going after 10 years' use (helped by occasional contact lubricant application).
I made a video about the slip ring capsules. If that's the one you were thinking of then you're right to be cynical about the current rating.
I would like a name and a source for the transparent "star effect" material to make my own design. Does anyone have any leads?
It's tricky to find. All that came up for me on eBay in a quick search was classic prismatic diffuser plastic.
Ooooh thats nice. I might have to get one. very interesting effect. 2x👍
you could make your very own police car blue light its a bit slow but still if it get people out the way. Im joking of course can you imagine how happy the rozzers would be pulling Ralph over with a custom in the back. 🤣🤣🤣🤣
Was that a little shout out to Dijkstra right at the end?
Not knowingly.
Sometimes the most beautiful things are simple.
Cool effect.
I saw that mechanism and immediately thought, "lighthouse." You could even use some of the fractal material to build a Fresnel lens.
Very nice 👍
wonder where you can get the prismatic film by itself
It might be available online in amongst the holographic or prismatic metalised films.
This looks good enough to buy is there a link
It's called Luxa in the UK. Not sure about elsewhere.
I like it... in fact I want one, no two now that it has a ringing 'Big Clive endorsement' re longevity. Cant find them for sale anywhere though 😒
Reminds me of a Jukebox that was in the juke joint my dad ran when I was a wee boy.
it puts one in mind of chatoyancy. cheers! very xmas BC!
Today I learned a new word. (I had to google it)
@@bigclivedotcom good lord. i informed BC of a thing! what a reversal of the usual order. i shall hold this moment dear in my heart!!
after a few moments consideration. once i stopped alarming the dogs and mrs by chanting "i made big Clive learn a thing, i made big Clive learn a thing" whilst dancing around my drawing room. i am still blown away by the perversion of the natural order obtained by me causing BC to learn a thing. this is the best xmas gift i have received since the horrific-ly hued Miami dolphins jacket i got for xmas in 1987. i am now going to drain a litre of vile sloe-gin in celebration! happy ruddy xmas! BC for PM!
