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
Last I heard a number of years ago it’s around $2000/sq ft. Around the same price scale as mid range LED wall modules.
All I can see are bars of gold.
Here’s a clip of it moving (doesn’t read so well as a static image): https://theartistbreakfast.com/works/oceans
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

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.

Net Zero Fatigue is real.
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!
Similar to all the ePaper projects that show up here, they’re expensive but cool gimmicks.
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).
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.
must be vrey annoying very fast if you have to sit next to it all day

Still, I wanna see and hear it on the display.
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.
But you can flip them fast/in parallel if you have a driver for each disc:

I've been working on one and I have and I am trying to use an H-bridge per disc. It's possible to find very cheap ICs; for my 308 discs, it only cost $10 for these (not counting the additional time/costs that comes with coming up with 616 IO lines, getting a PCB made, dealing with power issues, etc):
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.
EDIT: also when you google a bit you can find a guy who maxed out flip dot displays at 30fps (which honestly I thought would not be possible either)
Niche indeed...
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?
PS - Link to the ferrules they mentioned: https://www.amazon.com/gp/product/B07R6QQ7MW/
Ferrules also evenly distribute the clamping force and prevent crushing of the strands.
Ferrules solve the problem of having to align the threads every time you re-post them in a terminal block.
I think flipdiscs would be too expensive. Honestly a teletypewriter might be the most realistic, but wastes a lot of paper.
Any other suggestions?
I have notebook from ~15 years ago full of pie-in-the-sky ideas for different types of displays. This was before I got a job that took up all of my attention span.
It would be interesting to see if you could run a pared-down version of that game on a display like this.
Very cool project!
You’re not doing your cause any favors by projecting everything on an ill-fitting frame.
Sorry, I was half joking, half of me gets the metaphor, but the other me is seeing a wall of bricks of gold in a Las Vegas casino and gets another metaphor.
Either way it's beautiful!
I wonder if anyone makes cheaper versions that you're only supposed to update at 1 frame per minute or less...
Nobody outside a gas station wants a glowy hole.
The old panels had diode issues. It wasn’t the mechanism failing — the simplicity of electromagnets means they last an insanely long time, significantly longer than an LED. The diodes were just cheap and undersized. If you have a stuck disc on an old board, 99% chance you just need to replace the diode. If it still flips but gets stuck on one side, a pin has gotten sticky and needs graphite applied.
