    Neon was animated directly by using a special high voltage animator very similar to a car distributor using that same motor in your video. They used to come in 4, 6 and 8 circuits. Being a neon glass blower from the 70's I used those neon animators often. Marquee chasers used an off center circle contacting lever switches for the bulb circuits. For complex animations several cams on a common rotating shaft contacted lever switches. Very complex animations were possible. I've seen an animator with 40 cams.

      My father was a sign maker in New Hampshire. He built many signs with chaser lights. I remember playing with the chaser relays (older worn out units) in his shop as a kid back in the 60s. He had boxes of them on a shelf that he would use to repair others.

    My dad was into model railways back in the 1960s and 70s. He made something similar out of a Paxolin board with concentric rings of individual bent OO gauge railway track fixed to it. A spindle through the centre drove an arm with copper contacts that swept around the cut sections of the railway track, each of which was wired to separate circuits.
    We had the most complex Christmas tree and window light flasher in town.
    Fortunately he rewired the lights in parallel to run at 24v AC rather than British mains at 240v, and the transformer for the 200+ lamps helped warm the room in winter.
    The aroma of electrical arcing is something I still associate with the Christmas and new year holidays, along with the smell of 1:1:1 Carbon Tetrachloride that he would use to clean any tarnishing of the tracks (model railway and light flasher). Different times!

    My dad was an engineer and visited all sorts of places from oil rigs to sock factories. He told me that he once saw the switching equipment running the advertising lights in Piccadilly Circus in London. They are now big screens which you could probably run from a laptop or maybe even a Raspberry Pi but back then, 1960s I think, there were rooms full of relays clicking away using pretty much the same technology as telephone exchanges of the time.

    The not connected tabs are to avoid brushes connecting the two halves as they cross. If you were to use the tabs as contact, the brushes would connect the tabs to the half rings as they pass.

      The carbon contacts (like in brush motors) have high resistance to prevent shortcircuit damage, but this may also help to increase the lifespan of incandescent lights, because the cold filament has lower resistance and so heats up unequally during each power-on, forming local hotspots those finally burn out.

    Now I wish I could find it somewhere, but I remember seeing an old short from the Popular Science film series, which discussed how then-modern animated electriic sign boards used a matrix of lights controlled by a corresponding matrix of photocels on the back. The sysytems would use rear projection through interchangable scrolls of text printed as a negative on clear film. The demonstration had hula dancers on a platform between a bare projection bulb and the matrix, causing their forms to be displayed in negative on the lighted side.

Downstairs was a panel he made from scratch with 8 lights in a circle corresponding to the compass points on the wind vane.

    The digital version is a 4-bit ROM with the chase pattern, connected to a binary counter IC that feeds in an address to the ROM, and the ROM output leads directly to the 4 relays that control the 4 individual strands in a 4 strand chase animation, and a 555 timer chip controls the stepping of the binary counter. No microcontroller necessary. This is the actual circuit design used in the old Clean Sweep Skill Crane arcade game signs with the multi-stage chase pattern animations.

    Thanks Fran. Nicely made rotary switch, Tuffnol is a great material to machine. Some early moving signs used a shallow tray full of Mercury, above this was a perforated continuous roll with the text to be displayed, this allowed the circuit to be passed up to the individual lamp contacts above the roll. Some of these were several feet long and probably not good to be near.

Mounted on Bakelite then on a rubber sheet hanging in the damp corner of the trunk. After 23 years stuff warps but I was able to bend back to operation. Made quite a racket in the rear! Soon Ford/Merc moved to a transistor timer. (Same unit used on 1960s Thunderbird which justified a re-design.)

    The NYC Times square ticker was driven by paper tape. They would punch out the message onto a a paper tape. The machine would use the holes to make contact for each bulb on in the display. This is when the ticker started operation in the late 1920's.
    Nice vintage rotary switcher & very clean No oil, grease or grime. Those gears are probably not aluminum if there is a wire soldered to them. probably brass or bronze, unless its laminated some brass sheet metal for the connection. There isn't any way to solder to Aluminum.

    So I think the 2 small contacts are part of the separation from side to side, the brush needs to slide along the gap from one side to the other so it needs to have 2 gaps to keep from shorting out, thats why the little contacts arent connected to anything.

      I think that's part of the flexibility in the design of this part. As she said, I think they could also be used to have just one or two contacts sweeping at a time rather than the 8 at a time. I would think if they just needed the gap, they could have just cut a gap in the brass ring. 🤔

    This was very surprising - I have an utterly similar device, made in Poland and used in a "shock generator", a research device I got from the medical university. It was probably used in some experimentation on living tissues or even animals, and had multiple electrodes, with high voltage direct current applied by the motorized rotary distributor. Questionable ethics have unforeseen consequences...
    Even better, I got three or four of those shock generators, and discombobulated just one of them. The rest is waiting in my Vault... so I really have to make a video.

    Depending on the effect you're trying to get, It can be quite tricky getting the animation to look like it's moving in a particular direction. It's very easy to inadvertantly get a kind of optical illusion, where something may look like it's moving in one direction or the other. It's also very easy to create something which isn't understandable and just looks chaotic.
    I really admire the skill of the people who worked out the logic of the animations without using computers.

    The fairground ones are interesting too. Basically just a clock connected to a binary counter connected to the address lines on one or more EEPROMs, with the data output(s) connected to FETs, relays or triacs allowing for very long and complex animations. They could be switched between animations by just changing the high address bits, if needed.

    Many other options with this. The two one-point contacts can be wired to the long bars, and half of the terminals connected to power for advance (like an arrow lighting up in sequence to point to a used car dealer lot). There are likely extra holes in the frame plate for more gear reduction. There can be three static wipers (the one that is there, one for the other side, and one for the shaft, which is a spring at the far end, low load only, in the units I have dealt with).

A very eclectic and energetic bunch of individuals, they always told great tales and smelled so interesting! They also, despite common belief, were as honest as sunshine and loved and protected us kids whenever we were with them. By way of them (not always intentionally) I got to see many examples of how midway blinkenlumen are controlled, from the simple to highly contrived, all fascinating! I also learned to love the smell of corndog mixed with diesel fuel, to this day it reminds me of my Aunt May and her, as my mother would say, cocoa colored girlfriend, Nadine. Indeed, everything about them was colorful and in motion, RIP, all. About the device you have there, there's a wiring harness I believe with solid colored wires that you never spoke of or even showed how it attached, skipped right over that unless I missed it. The screw contacts around the outside have thinner, two-colored wires that have been cut, I wish you had shown the other side in the back where the wire harness looking thing attached.

    As it is set up, I think it was an "Off" chaser where it's interrupting a couple of circuits (creating a wave of darkness). There may also be a circuit to deliver a small amount of power to the circuit that is "Off", keeping those bulbs' filaments from breaking due to the rapid cycling.

I was thinking a flat plate with a bunch of brass buttons each with a wire and an armature that connects them in sequence as it rotates. Then to do a lil delay I'd make a series of relays, one per light; that one relay closing turned on another light and closed another relay, to give a quick but delayed shimmer. Maybe going diagonally in a matrix like 40 lights wide by 120 long.

    If you're driving an array of incandescent light bulbs, the "off" switch contact would probably need to be connected to a slightly lower voltage supply - just enough to keep the filaments warm but not enough to emit light. On slower versions of this device the connection to the gear shaft at the back possibly served this purpose. However, at the speed this one turns the bulbs won't have much time to cool down anyway, so the contact spring to the shaft has been omitted.

    With the resistance of the carbon contacts, it is probably possible to use it to bias the gates of MOSFETs. Use quite a high value pull-down resistor (100K or even more perhaps) just to stop the gates floating when the contact is open, and feed enough voltage into the switch so that despite the contact resistance, the gate voltage is lifted above its threshold. The gate needs essentially no current, the only current flows through the pull-down resistor. Then the MOSFETs can switch the load current needed for LEDs or whatever.

    Thank you for this video. I recently had a book out of the library about animated light displays. The most elaborate ones were called "spectaculars" and there was one designer in particular who was famous for his spectaculars. I can't recall his name, however. In addition to light chasers, they sometimes had "smoke" effects using steam. For example, for cups of coffee or somebody blowing smoke rings.
    The climax of the Jack Benny movie "The Horn Blows at Midnight" takes place on such a sign. The fact that this movie was a flop was a running gag on the "The Jack Benny Show". (I enjoyed it as a child.)
    I've recently done some work involving virtual light chasers and even with all the power of the computer, they are an immense amount of work. I plan on making a breadboard version with LEDs. I'd like to use real neon (not for the chasers, but for animations), but I'm somewhat wary of the high voltages and I'm not set up for expensive industrial processes. I could probably get my program to run on a Raspberry Pi, but I'm not sure if that would be "cheating". It never occurred to me to try to implement them using analog circuitry only, but I think that's a better idea, so thank you for that, too.

    Decades ago, I got my hands on what I believe was the Chaser mechanism from a mall deli’s sign after it folded. It looked hand made. On a maybe 9” by 12” piece of wood, there was a synchronous motor. On its shaft were 4-5 5” or so aluminum discs. They triggered roller micro switches. Supports were hardware store angles; the connections on old type barrier terminal strips. Don’t know if it ran a bunch of relays or ran right to the bulbs.

    All right, here is mine: czcams.com/video/39RHIoa7gaY/video.html
    Very similar. Driven with a shading coil induction motor, 18 contacts. Also a bit different: no die-cast aluminum, no ceramics (or teflon?), and it uses a worm drive which is way simpler and cheaper. Mine also seems to be turning slower.
    My wild guess is that it was custom made by the Polish Academy of Sciences Experimental Biology Institute in Warsaw, the makers of the shock generator I took it from. Who knows, maybe the engineers found an US patent for yours and copied the design with cheaper technologies available in 1970s Poland?
    These short sections are there for preventing a carbon brush from shorting the live and ground half-rings. They have to be the same diameter as the whole rotor, otherwise the spring-loaded brushes would fall in and jam the mechanism, or become sheared from torque and eventually completely destroyed.

    I saw a simpler light chaser (maybe 3 or 4 circuits) which used cams driven by the motor to actuate standard (large, not mini) microswitches (the type with roller levers). It made a constant racket of clicking while operating, so I guess it would mainly be used in big signs where it was far from the ground and the noise wouldn't bother anyone. Benefit was the ability to easily change switches that failed, or also the current capacity could be varied depending on what spec of switch was used. So much mechanical ingenuity, so readily and eagerly replaced by semiconductors once they became available. Don't get me started about washing machine controllers...

    One thing this device makes me realise is that we have to do _more_ now than we once did to get the same effects. This device simply connected power to the bulbs directly, and the natural fade of filament lighting meant getting that _afterglow_ was just a matter of turning it off. Today - With LEDs - You have to connect it to a PWM source and _actively program_ that effect in, which of course requires an MCU and additional instructions (And ROM space) to support it. 😲
    The more discrete part of my mind thinks the same might be possible through on/off control with the right value of capacitor in parallel, but if you've got a 50,000 LED sign and want each of those LEDs to „fade“ without needing PWM control, that's a *lot* of capacitors (And budget increases) you're talking about... 💸😇

    It doesn't really matter what the contacts are. Every sequencer has a counter and potentially a decoder. That motor acts as an eight step counter. From there, you can add all kinds of decoding logic to control which lights are illuminated at each step.
    We'd do the same thing with electronics except that we would use a shift register or binary counter to keep track of the steps.
