i'm sure i'm not the only one who wanted this information: >AlfaZeta makes brand new displays, with a controller board. Their XY5 displays (14x28) sells around 500€ (VAT and shipping included). https://hackaday.io/project/159415-flip-dot-display-diy-cont...

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.

What is up with the URL?

Excellent question, it should probably be changed to https://flipdisc.io/ (truncating everything after the first /)

You could also have a look for used bus signs on ebay, or I imagine scrap yards might have them too. I got a 14x20 display for around £50.

It's this misline in your html

What? The display is made almost entirely of moving discs.
