> We used 9 Alfazeta panels in a 3x3 grid or 84x42 discs. Each board has (2) 28x7 panels.
So how much do one of those cost? The website (https://flipdots.com/en/products-services/flip-dot-boards-xy...) notably has no prices listed.

This [1] page talks about 500 EUR per display which would result in about 3000 EUR for a 3x3 grid or 1.27 EUR per pixel.
I love the idea but that's WAY to expensive for me.

#43Kath - so cool to see this is you! What a great project. Well done.

#44Earlier quoted context omitted.
I was about to post the same. The result is really nice, and makes the conclusion make a lot of sense. > I do hope that flipdiscs become more accessible for hobbyists. If anyone wants to collaborate on new affordable flipdisc hardware, let me know! €4500 is quite the pill to swallow (unless prices have gotten cheaper since that 2018 Hackaday project)
I paid a fraction of that. They'll come up on eBay every once in a while.
great to hear!

#45This is incredibly cool! Does the video audio amplify the sound of the discs flipping or are they really that loud?

#46Breakfast studio offers some amazing art pieces using Flipdisc modules. https://breakfaststudio.com/flip-discs
Having silver on one side and an abstract/neutral design on the other side is an excellent effect

They can be a little loud, but I find it pretty soothing, tbh. It's sort of like a rain storm.

#48How do they have no moving parts?
The disc moves, but there aren't any moving mechanical parts to cause it to move. It's done with electromagnetic pulses. I'll update it to make this more clear.
I don't really see what the distinction is?
You might as well say a motor has no moving parts, because it's done with electromagnetic impulses. But that would be absurd.
Obviously the hinge of each disc will wear and tear and eventually fail. Buildups of dust and oil will affect them too and prevent them from flipping. Flipdiscs are as mechanical as mechanical parts get.
You writing in the intro: "...have no moving parts, near limitless lifespan..." is just not credible.
And if I'm being entirely honest, that's where I stopped reading your post, because you simply didn't seem trustworthy. You might want to focus more an accuracy rather than hyperbole if you want to maintain readers.

#49> Flip displays are an interesting alternative. They have no moving parts, What? The display is made almost entirely of moving discs.

#50I built a lo-fi device like this (with a LED matrix instead of a flipboard) and I didn't really find great software for building animations at a low pixel count. I ended up doing something super low level where I draw to a buffer directly using ImageMagick. If there's a better library I'd love to know.
