I love physical displays like this, or split flaps. Anything that is not a screen, and keeps it's display without power. I keep getting ads for vesta boards, but I just can't justify the expense.

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.

Earlier quoted context omitted.

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 qu…

These mention 25-30 fps, so the mechanism may cost a bit to be that sturdy.

I wonder if anyone makes cheaper versions that you're only supposed to update at 1 frame per minute or less...

I think a missed opportunity on the website would be to have a flip button to change the colors pallete too! White background black text and flip back to the current one!

Very cool project!

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.

They can't if they are wired like they usually are from the factory, because they are wired in a matrix where you can only update one row at a time. They did this to save on IO lines/output transistors, I guess. So you have to wait for the whole screen to finish drawing before beginning the next frame.

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):

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

You'll get to it when you get to it. After 2 years, I've just been working on my flipdiscs this weekend!

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

Interesting, that "fade away" effect looks almost exactly like what I see when I get a migraine aura.

> "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, ... All I can see are bars of gold.

BREAKFAST (AKA Zolty) here. The “ocean” aspect of the piece is in how it moves and the real-time API data that drives the wave-like motion. It grabs live tide data from a different coastal city each minute and changes based on that. The gold and marble bricks took inspiration from the Fontainebleau art deco style of their original Miami hotel (this piece lives in their Vegas location).

Here’s a clip of it moving (doesn’t read so well as a static image): https://theartistbreakfast.com/works/oceans

Maybe we should both stare at walls more than scrolling on HN.
