> "Oceans" is a kinetic sculpture that embodies the dynamism of the world's oceans within the arid landscape of Las Vegas. Crafted from 483 motorized elements known as "Brixels," this piece mimics the movement of the sea's surface. The sculpture is alive with the pulse of the planet's waters, ...
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
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
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.
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.
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!
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.
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 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).
There’s a very large one of these at “Climate Pledge Arena” in Seattle. Perhaps 8 feet tall and 16 feet wide. Pretty cool, but stuck pixels are even more annoying when it makes you want to reach out and poke them.
I use quotes because it will always be the Colosseum to me, where I saw the Butthole Surfers, Dead Moon and Nirvana. Don’t get me started on the Kingdome.
I bought a flip dot display on eBay and now I am stuck with the old thing and my lack of knowledge to make it work. Here's a great resource about technical details (only German though) https://radow.org/flip-dot.php
EDIT: "They have high readability, a long lifespan, and achieves anywhere between 25-60fps" - I think you can't achieve 60fps with a flip dot display.
Depends how much power and noise you're willing for it to make!!
Remember that texas instruments DLP technology which is in use in pretty much every office/home cinema projector is effectively micro flip-dots micromachined in silicon, and that can operate at ~10,000 FPS.
It's crazy that I was trying to find good resources for split flaps and then flip discs just yesterday and was just thinking, damn, there aren't any good or recent information about flip discs, just decade-old proprietary stuff to be found
Great work!
If you're into electromechanical machines, he also has a working telephone exchange and a bunch of videos where he restores its various components and explains how it works (I still don't quite understand how it works though). That's the original reason I subscribed to his channel, but his wild musical contraptions are also cool.
I remember seeing those at the airport when I was a kid it was fascinating, one of the screens was close to the ground and I got over the chairs just curious how do they flip, now we have the boring soulless LEDs.
I have a question about those wire ferrules they said they were using:
I occasionally connect wires to terminals, but - I've never used ferrules: I just self-twist the thin strands, push the thing in, and use the lever or tightening screw depending on the terminal's mechanism.
Why would I use a ferrule? Or perhaps, under what circumstances is that advised?
The wire will crush over time and the connection will become looser. That will increase the resistance of the connection and in high current applications will cause heating. If you're really unlucky it will cause a fire.
