I've been after a flip-disc setup for quite a while and now there's finally been one released at a reasonable price on Kickstarter - Flip-disc Displays - Arduino Based from Marcin Saj.
There's a number of reward options in the campaign, I've gone for the FLIP-DISC CLOCK but I can see me getting others later, would be awesome to build a bigger display.
The timeline is looking good at Feb/Mar 2024 but it's becoming popular so that might delay things, but this will give me time to finish tinkering with all the other projects I haven't started yet!
