splitflap VS arduino-eurorack-projects

You might want to check out Scottbez's open source split flap display project (https://github.com/scottbez1/splitflap). I've also been interested in replicating/streamlining this someday since I don't like the idea of manually applying vinyl lettering to all the PVC cards.

There is a wonderful resource for a DIY option here: https://github.com/scottbez1/splitflap

https://github.com/scottbez1/splitflap Found this long time ago, but is too complex for me

For what it's worth, I've been keeping an I on https://github.com/scottbez1/splitflap for some displays. At some point they have a easy version.

I was looking at these the other day - in the process of browsing around the subject I found this maker-project to create custom ones:

https://github.com/scottbez1/splitflap

This is based off the splitflap project, which includes ordering and assembly guides.

Scott 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 a large portion of the cost being the custom cut "flaps" (in small quantities). It seems like the cost could get in the $2-$4 range per character but I couldn't figure out how to do it without a significant amount of labor involved in cutting the flaps.

FYI, there's also a company called Oat Foundry that sells large split-flap displays [4]. I seem to remember the cost being in the $10k+ region but I don't see a price and I could be way off base.

Oh, interesting, I see Vestaboard also has a (smaller) one for around $3k [5].

JoeSeggiola's Clock divider and Forks modules are also on my list of "next to build".

The Circuit Abbey TICK is a simple 555-based clock with three ranges. After that there are any number of divider options, including the 4ms Rotating Clock Divider.

Well, Arduinos are awfully powerful, tiny and modular. For example: Time Manipulator Pedal or this Arduino Eurorack Projects

Anyway my projects I had to make things a bit more general (read: MIDI pitch-bend) and memory efficient (read: 6 different DACs with flash and RAM already at their limits). I recently implemented a multi-point interpolation map, adjustable at run-time, based on pre-existing work (Befaco, Mutable Instruments).
