They blink and they sync: synchronized blinking cat ears.

At first glance, rudelblinken is just a pair of 3D-printed cat ears with blinking LED strips. But if you want to build your own, come by—we’ve got a mountain of kits and a soldering station.

If you’re more interested in the nerdy side of rudelblinken, we can tell you all about the boards (ESP32-C3), the firmware (Rust-based with a WASM VM), or the software. You can also try writing your own software using the rudelblinken SDK and experiment with things like mesh networking.
