It is so sad to see both this and the title "It's ok to abandon your side project" on the front page while I have three flipdisc displays sitting in the basement without the time and equipment to get them up and running.

No, it's not ok to abandon those flipdisc displays! :(

Admittedly I read neither of the articles. But who doesn't sometimes get caught up in the conincidence of titles on here may vote me down :D

Andrew Zolty under the artist name BREAKFAST has created quite a few stunning kinetic artworks with flipdisks.

Just one example: https://theartistbreakfast.com/works/traverse

Also created a larger more sculpted derivative the „brixel“ a rotating brick as pixel. Eg https://theartistbreakfast.com/works/oceans

There is a fairly impressive installation of these at Heathrow airport in Terminal 5 outside the BA lounges. Struggling to find a decent video on YouTube, but this one’s not terrible https://youtu.be/G03WA30yFMI?si=hx5aLlrj_BH21yr2

I wonder how small they can be. Would be an amazing watch display.

I did the same for my office and bought used LAWO flipdot panels for this. Screenshot of the thing here: https://github.com/aivju/flipdotz

If I’m not mistaken (their pricing is a bit hard to find), nine of the flip fits display modules will set you back ~$5000 alone, plus the rest of the hardware. While I love the idea that is a lot of fun budget for other projects…

Thanks, I've been looking for that. Interesting how nowadays it's orders of magnitude cheaper to buy a 4k 65" panel and fake the dots (and sound) on it.

They've been slowly replacing the flip-disc displays on the buses where I live with LEDs and LCD panels which has been such a shame. There is a beautiful mechanical satisfaction to a panel of flip-discs inverting and I genuinely find them easier to read.

They seemed less reliable than LEDs. When they were common here they would always have tens of dots stuck in the wrong position.

I'd imagine the vibrations didn't do them any good

Interestingly, I've never noticed any stuck discs. I'm pretty observant of them as well, because I think they're so cool.

The ones here could have been nearing the end of their life to be fair. They have basically all been replaced with LED signs now.

The Luminator MAX 3000 is an interesting hybrid between a flip dot display and an LED display. I find it very pleasing to the eye and easy to read, particularly at night.

In front of the flip dots is a frame that has a mini-LED that faces and front-lights each flip dot. This gives the appearance that each flip dot is glowing.

Yes, even the ones that have an LED behind each disk which are on in the dark. This display [1] is the same but in the dark [2] you see the LEDs instead.

The LED / LCD displays are probably lighter (less heavy), and someone figured they can save 0.001 gallons of diesel a year fleet wide if they replace displays.

Net Zero Fatigue is real.

Much more likely, I think, the mechanical displays had some maintenance cost which cheap LED displays will not.

You've confabulated a reason why they replaced them, linked it to initiative then complained about them doing it all in two sentences. A gold medal in mental gymnastics is warranted here!

They’re probably just cheaper and require less maintenance.

You’re not doing your cause any favors by projecting everything on an ill-fitting frame.

> as a pleasant bonus, they emit a sound like rain hitting a window each time one of the disc flips

must be vrey annoying very fast if you have to sit next to it all day

Damn, I really wish there was a T in "Quick jazzy vibe flows from exploding pixels", 'cause the sentence is just cool!

From the exploding pixels and then you're fine. You needed an H as well anyway.

This is insanely cool, the noise they make is also really satisfying!

What was the cost/time breakdown of the entire project because the flipdisc prices are hidden behind quotes and it seems like it would take quite a lot of time to complete the whole display!

The prices I’ve seen mentioned are around USD$3-5 per “pixel”.

Similar to all the ePaper projects that show up here, they’re expensive but cool gimmicks.

Whole dollars per pixel is insane!

The whole mechanism looks very 3d printable... I wonder if one could design one with PCB coils and a large 3d print only? If so, cost could probably come down to cents per pixel...

You'd probably also need a single 'C' shaped piece of steel for the magnetic flux path, but you might be able to find a supplier for the right shape already used for something else you can buy in large quantities very cheaply (eg. Steel staples).
