from the HexLed store; "I was selling about 4 kits a week, so keeping on top of the stock was easy. Then Big Clive released his video and I sold 46 kits in 2 hours and I have had to close the shop to catch up." I can't help but feel warm and fuzzy for buying out someone's shop. ^.^

Back in my pro audio days, we used to put something called "LPD" on our equipment spec spreadsheets when comparing possible equipment choices. LPD = lights per dollar. If the rack was a show piece, high LPD equipment was sometimes chosen so the client felt like they were getting something for their money. The DSP boxes we often used had a single red.poweer.light on the front and weren't terribly interesting to the uninitiated.

That's just like having people go "I want those shoulder mount camera's, that looks good" while a much smaller one these days might be just as capable though yes you might see it in the resulting image when it comes to dynamic range when you knew what to look for. Best thing was when having hired 4 of those big ones and the job was over, you later heard the customer saw you at so many places due to having to move a lot with them (in a multi-camera setup for instance) they thought you were there with 6 of those camera's :P.

[@brucewhiteside1741]

Back when I was in college ('68-'72), I built a similar device with NE2 neon lamps across a unique hi voltage polyester capacitor with each cap/lamp in series with resistor. All of these were powered by a mains connected bridge rectifier on the USA 120 vzc power. The same random flashing of each neon lamp was mesmerizing. Also, in a dark room, the lamps could re-synchonize because the orange photons from any lamp could trigger nearby lamps optically. Much fun, then and now.

[@jkobain]

Some people can actually recall that old computers displayed their registers' state by lighting up corresponding bits on a panel and populated huge rooms with their circuitry. This is what influenced, I guess, the look of «supercomputers» in Sci-Fi movies, especially where blinking in the dark rhymed with sky full of stars.

[@ihateemael]

don't forget Star Trek. Terribly high tech in the seventies. Remember when the Star Trek computer said "working" in that sexy female voice?

[@tncorgi92]

I worked at a financial firm and someone they hired to do a brochure came around snapping pictures of the various departments. I had to escort the guy through our computer room and showed him our IBM mainframe. He appeared frustrated and finally asked if we would show him the "insides". He was expecting huge panels full of blinking lights just like a sci-fi show. Disappointment. Then he asked if I could make the workstation CRTs display any cool graphics. They were green monochrome 3191 "dumb" terminals, so no. We were a financial business and he was looking for LucasFilm or something.

[@dragonrider4253]

I have had a MASSIVE fascination with LEDs that do things on their own (flash, fade, color change, etc.) for many years now, and this tickles all of those fascinations. Especially high amounts of them in one place. I think it all started with a flashy dragon I got a while ago with the blue/red flashers. Similar to what you showed, they all start on red then slowly become un synchronized. I could watch it flash (and those boards too) flash away all day! I love it!

[@K-o-R]

[@1kreature]

Haha, I was also yelling at the screen at this point. 4 from the back, second row from right at 13:53 shows a white one and on 5'th from back first row from right has a red one sticking out as well. That's the first time we see em.

[@Nono-hk3is]

If you drive multiple blinking LEDs from a single resistor, they will tend to blink in sync. It occurs to me that someone very clever could lay down runs of sync'd LEDs so as to cause specific shapes to appear.

[@greenaum]

Something along the lines of Clive's lamp with the neons that did the same thing, I was thinking of that myself. I wonder, what if you put two in series? Or two in parallel, then those parallel pairs in series? I dunno, there's all sorts of things you could do, stick resistors and capacitors in here and there just to introduce more needless complexity. Sadly though, chaos theory works best with large groups of identical units, the base layout should be as even and boring as possible, so that the tiniest differences end up producing the big results. When I imagined there might be a computer on there, I thought it'd be nice to do Game Of Life. But not Conway's rules necessarily, cos they're pretty sparse and boring and degenerate into nothing pretty quickly. But you can alter the rules so that any number of live neighbours causes birth and death, and get all sorts of interesting results. Maybe something like that, that on a timer randomly chooses a new rule. Actually back in the early days, Conway knocked up his own purpose built game-of-life machine, it used RAM and logic, I think, to read and compare the neighbours for each cell, without having to do it in software, so it was much faster. I think you'd interface it via serial to a normal computer, point being it could tear away at a decent sized grid much faster. I used to really want one, at one point, but now there's wristwatches could do it in software faster. Maybe an FPGA would be good for that. The tricky bit would be the addressing, though I once implemented GOL in software and came up with a couple of shortcuts, since for each new cell you evaluate, you already have some results left over from the previous one that are relevant.

[@mySeaPrince_]

I'd been wondering why not one resistor ... Have a lower voltage? Or is there something weird going on... Like the videos that are happening at the moment about a circuit that's speed of light related... Aerial Capacitor Inductance Circuit ... 🐱 ...

[@km5405]

can probably write a script that figures it out relatively easily if that is indeed the case. i say script because a complex shape is likely goingto melt your brain and collapse your patience into a singularity.

[@nonchip]

@@mySeaPrince_ not _quite_ sure whether i understand your question correctly given the completely unrelated random words you sprinkled in there, but i _think_ you meant to ask why all the LEDs didn't share a single resistor? in that case the answer is: because then all the current will go through one big resistor (= it'll heat up way more), and also the fewer LEDs are on at the same time, the higher the current will be through those, possibly damaging them. the only way to prevent that would be to make the resistor such a high value it would protect a single LED, but then as soon as more LEDs are on the current across them individually becomes so low you can't see them anymore.

[@tissuepaper9962]

What if you added a photo resistor pointed at each LED, and a random web of traces on a middle layer connecting each photoresistor to another LED somewhere else on the board. You should end up with the frequency of each light's blinking shifting randomly around.

[@Spiralem]

I like how simple this design is.. Just by relying on the manufacturing tolerance of the on/off timing.

[@CyberlightFG]

The resistors got much higher tolerances

[@Spiralem]

@@CyberlightFG in this application, resistance just controls the brightness. But it shouldn't be noticable to the naked eye

[@andersjjensen]

@@Spiralem Well if the timer is capacitor driven instead of crystal driven, you have two tolerances stacking up.

[@tissuepaper9962]

@@Spiralem I very sincerely doubt that the external resistor has no effect on the blink rate. It's not like there's a microcontroller and a crystal oscillator in there, it's probably some sort of simple oscillator IC and a capacitor to hold the energy for each blink. The simplest circuit I can think of would literally just be a capacitor connected across the terminals of the LED, but a cap that small would flash too quickly on its own. I doubt it's much more complicated than a few transistors, but I honestly could be wrong.

[@DarrellLarose]

Don't forget the "Seaview" Submarine ;)

[@dustinsmith8341]

One technique I use for when placing lots of LEDs is to line them up in the positive and negative rails of a bread board. Then I can test all the LEDs for matching brightness. Then when I go to put the LEDs into the PCB, I snip the LED standing in the bread board so I always know the polarity directly before placing it into the PCB. they stand up nicely in the bread board which is easier to snip, and also the legs are easy to clean up because they remain in the bread board until you pull them out.

Funny, I used to make these way back in the early 1990s when the blinky leds first came out. I used to make small 12v red versions in a bezel (still have one) for car dash boards before alarms were the norm, so it looked like you had a car alarm, and a thief would leave your car alone. Sold many hundreds (lost count) for $15 each. I bought thousands though, and noticed same effect, so also made large blinking panels from old populated pcbs, and sold them for hundreds of dollars as supercomputer tech art.

Surely to make the cube version, you just substitute non-flashing white LEDs, where the "edges" of the cube are? Or am I missing something?

[@Rac00n]

@@BedsitBob If the person selling it supplies rgb leds then sure, if the kits are only sold in solid colors you might need to buy 3 (or leds from ebay)

[@Torbjorn.Lindgren]

@@BedsitBob No, the RGB LEDs (not currently available) can't be used for that since those RGB LEDs aren't controllable - they slowly cycle between colors. So you need three sets of different coloured random LEDs, and you probably want the "Slow" type which as Clive mentioned are not easy to get in small quantities except via these kits. Yes, sourcing the white solid diffused LEDs for the border wouldn't be hard but that's not where the problem lies, it means you "only" need 3 kits to build one instead of 4. Assuming the Etsy selller offered the colors you want or even has three different colour variants (it has 3 currently, but not the ones used in Clive's cube) - it varies depending on supply. OTOH if you want a solid or Fast blinking Cube it does mean you could buy just one kit and ignore the LEDs included (there's currently no "bare" kit). Not sure if the PCB layout files for it are available, but even if it is doing all the SMD resistors on the back will be a pain. Not that hard to do if you have a steady hand but will definitely take much longer to assemble. I suspect it would be a much better idea would be talk to the Etsy seller, he/she may well me willing to put up a Cube kit if asked. Or even offering a "bare" kit with just the circuit board and smd resistors already soldered.

[@chadp6307]

@@BedsitBob For me, the idea of a "kit" means everything needed is included. None of the kits currently offer having a 2nd color to use for the cube edges, so I would have to source other LEDs separate from the kit. If I were to buy 4 kits of different colors, I could then mix-n-match the colors to make an edge color and have 3 colors for the sides. That could be repeated 2 more times, and the 4th would just be a mixture of the leftovers. In the end, with what is currently available, buying just 1 kit won't get me the "cube".

Most awful is when I have lane-PCB and for convenience I want to bridge lanes (for instance for a common ground from somewhere) and the solder is like "Nope!! I won't do that no matter how hard you try!" and when you need to avoid a lane or islands getting bridged solder is like "Here you go!" :P.

[@fyrrydr4g0n]

My dad did something similar to this, but with LEDs that do a slow RGB color fade. An acquaintance of ours who was a regular attendee of Burning Man had managed to get an old electric golf cart and wanted to give it a dreamy / etheral look, so my dad put a bunch of RGB color fade LEDs in parallel on some thin wire and powered it with an LM317 set to 3.5V. The ceiling was covered with a few layers of a thin decorative glittery fabric with the LEDs behind most of the layers. It made a cool subtle morphing effect across the while roof liner. I wonder if I can make that effect happen in a smaller footprint and make it look like a computer having dreams...

One of the two resistors limits the discharge current of the capacitor, because otherwise the electrode material of the glow lamps will be sputtered away.

[@AlienWacker]

Very cool looking project! Wouldn't a blinking LED not actually require a current limiting resistor? I would think that the blinking circuit would take care of that at the same time??? (Still quite new to electronics, so any advice you guys can give would be appreciated....)

[@bigclivedotcom]

Direct across 5V the current could be quite high. Using separate resistors also reduces LEDs getting in sync, and also protects them during a reverse polarity incident.

I need to design one of these that fits into a 19" telecom rack. We reduced a huge amount of our data center into a dozen hypervisor hosts (so maybe 30-40 racks of stuff down to one) - would be nice for management to think there's still tons of work going on there.

[@tbelding]

Look at the Post Apocalyptic Inventor's channel. He shows a set of rack mount props that he put together.

@@tbelding nice 👍

@@Okurka. - that's one word, yes. das cottenpicken hander? 'das pockets'? 'rubbernecken'? .. all strung together? At least you didn't end up adding something like Abwasserbeseitigung. (Or maybe in defense of Arbeiterunfallversicherungsgesetz, or someone having backpfeifengesicht )

I like this. I love the red border. Red to Red Black to black Blue to bits

[@der.Schtefan]

It's amusing to me how you always inform us how to reduce the intensity of LEDs (to tame them, to make them background lights, to increase longevity), while here at my house I deliberately get the highest lumen counts and plaster my house in lights so it is brighter than on a summer's day 24/7.

[@drsquirrel00]

You can always go for even higher rated lights and tame them ones down. The goal is to get what you want at reduced stress to components.

[@grayrabbit2211]

This just needs a prismatic lens over the top of it to make it period-appropriate. I had a toy as a kid which had flashing lights behind such a lens which made each one look like a starburst.

A project idea might be to have a multi-colour version of your channel logo for your live streams. It could sit above your head and have shimmering eyes and a shimmering beard? Alternatively, you could make a sign with the word 'live' underneath your logo maybe even featuring an electric blue lightning bolt. Awesome effects in this video and really simple to do.

[@knoxieman]

Superb video, just ordered a supercomputer got just the job for it 😎😎

[@RobWVideo]

13:52 "I'm also noting there are none sticking up to an undue level" as your right index finger taps right next to a sticking-up LED.

[@Vixiea]

Love the project, just ordered the yellow hexputer myself.

[@tristanwegner]

Hey Clive. What do you think about the recent boom of LED Pixel arrays? They are unusually individually addressable RGB Leds, where you can upload patterns via bluetooth. Divoom has a few from 16*16 to 64*64 and many thousands of user made animations, some quite good. A teardown would be cool to see.

[@Petertronic]

All monitors are LED pixel arrays

[@tristanwegner]

@@Petertronic No. Most monitors are still LCD. Some Oled. HiRes LED screens are very expensive to make and are just coming to market. OLED is somewhat established, but suffers from burn in.

After watching the Patreon version of this video, I bought 2 of the larger mouse ones in green, because this gives the best simulation of the HPE SGI 8600 Supercomputer cluster networking and compute blade indicator lights which I work on.

[@StuartYoung]

The orange hex one! Immediately thought of Zen from Blakes 7 saying "Confirmed".

[@richards7909]

Moar litez! These are great, but my fave is the hexputer although the cube computer is a close second!

[@bunnykiller]

you convinced me that I just had to have one... so off to Amazon I went and ordered a combo of single, dual, and triple color fast and slow flashing leds for a total of 600 of them... plan to mount them in a sheet of lexan and spray paint the back side flat black... gonna be fun soldering the bus wires to the led legs and resistors... thinking of the design shape to be an ellipsoid...

[@justingrey6008]

I don't miss soldering LEDs... Worked in a place years ago soldering, could do 4 thousand LEDs a hour... (Components placed already) I was unaware that blinking LEDs were available, got some ideas now.. Thanks for the video!

[@The_Petrichor]

What resistors were used on the hexputer? Evolution shut down his orders, but I managed to score my own LED's and whip op my own gerber file. I just need to know the value.

[@bigclivedotcom]

1000 ohms.

[@davemoore7442]

To make soldering easier on ground planes and thicker tracks the component pad attributes can be set to 'thermal break' before ground plane flood is applied. Although this is not done for high current component pins.

[@KericthePally]

You've depleted all of Evilution's stock already Clive! Seems like he's having to restock due to popularity (no bad thing)

[@benaerialsbedford]

Thanks, Clive... I now have a sudden urge to dig out my Betamax recorder and "Blake's 7" tapes... 😁😆

[@billfusionenterprise]

FYI, I have a hat which had a flasher LED in series with two regular LEDs and worked off a 9 volt. Worked quite well. I did a project which used six flasher LEDS with a six LED element (radio shack) and it simulated a fire quite nicely. This might be a neat thing to try in a 12 volt light up panel.
