I wonder if there’s a way to speed up the rotation rate by making the stop adjustable. It matters more if you try to go beyond A-Z0-9

Re: Open source “split-flap” mechanical display
#92Scott Bezek has a great video on "How a Split Flap Display Works" [0]. He also sells blank "flaps" on Tindie [1]. The documentation on how to build the Split Flap is also really awesome [2], including how to cut your own flaps [3]. I've been following this project for a while. It's pretty awesome. I estimate about $10 per character (as opposed to the $180/character (!!) another poster mentioned through Alibaba), with…

They probably won't. After a flap has passed the upper lip, which is kind of holding it back to have a precise "flipping point", gravity will take care of moving it down. No gravity, no flap. ;-)
You could use suction or flow of air to overcome this. Or perhaps even a spring.
Or just some kind of display that does not rely on gravity, yes.

I really enjoy Alec's videos and quirky humour. Beware though, this kind of channel is a massive, addicting time sink. Other similar channels that HN might appreciate (the first two are quite well-known, the last one I found recently and is definitely bingeworthy): - Smarter Every Day https://www.youtube.com/channel/UC6107grRI4m0o2-emgoDnAA - Tom Scott https://www.youtube.com/user/enyay - Practical Engineering https:…
Stuff like this is why I have difficulty giving up YouTube. I've given up basically every other algorithmic feed (except for HN, I suppose) but the amount of passionate and engaging education and curiosity content on YT will have me hooked for a while I suppose...
YES! I'm also really struggling with giving up YouTube due to all the wonderful content available there. I wish there was a widely-used alternative like Floatplane to double-post your videos for your supporters.

eh? It's DIY. Make them out of whatever you like.
They're intended to be laser-cut, which limits the materials. Those flaps and wheels really want to be injection-moulded from ABS, with round pins at the flap ends. That would be cheap if you were making enough of them. (I miss TechShop. They even had an injection molding machine good enough to do this.)
yes i very much miss TechShop. i was a lifetime member. too bad they tried to grow too big, too fast. i think they misunderstood their business, at a fundamental level.
the techshop 2.0 guy was a travesty.
