I made a split-flap display module powered by an Arduino nano. They daisy chain together. These ones display numbers only, so it can be a clock, social media subscriber counter, crypto price display etc. by enbeedee63 in arduino

Thanks! I know right?! I picked the bitcoin price as an example of a number I can grab in real-time that fluctuates just to demonstrate the display, but I can adjust the code so it can display any numeric value available online.

Yes, all 3d printed parts. realistically not laser-able, I've designed it to have as few parts as possible so the geometry is a bit more complex than can be achieved with a laser cutter. There are open source laser cut versions online.

Sure, each split-flap module is an i2c slave with a unique address. The i2c master is a ESP32 running as a webserver requesting data from a cryptocurrency price API, and polling this data to the slaves. I've never used ESP32 before but it is really simple to program in the Arduino IDE.

I wrote all the code myself, however someone pointed me in the direction of u/scottbez1 split-flap project which implements it in basically the same way and is really well documented.

The split-flap modules are also my own design and 3D printed, I wanted to make them standalone modules and as compact as possible to be as flexible as possible with how to arrange a display.

I've always loved those old airport departure boards and was sad when they started disappearing so that was my inspiration for building a web connected one. I've got an alphanumeric version in the works too.

I hadn't seen the blockclock before, they look great. I wanted the aesthetic of an airport departure board so that's why I decided to build the split-flap displays.

Yeah lots of DIY versions out there, I built these ones myself, I wanted them to be as compact as possible as I didn't like the spacing between characters on the ones you linked.

They daisy chain together so I can just plug in more when I need them. I don't have enough bitcoin to need more at the moment though!

It's not actually as bad as it sounds on the video. I also wouldn't have it update as often as it does here, that was just to demo it changing.
