Hack the Crab

myminifactory

Crab that blinks and produces buzzing sounds when pressed. A blog post about this crab is here.   When printing the housing, double-check if the support is placed properly.You might need to adjust support distance to structures. Crab Infill Mod is for printing holes in Crab Bottom, for a buzzer sound to escape through.In Cura, it is possible to use this model to define infill-only area with no top/bottom. The firmware is here, it is written in rust, and can play nokia tunes (but you have to recompile to change the tunes). You can also write your own firmware (the hardware is very simple), or simply develop your own hardware. The crab runs on a common CR2032 cell. All other resources (schematics, pcb) can be downloaded from here. The project is open source and can be used however you wish, only a backlink to this print or the blog post would be appreciated.   Go crab! Go nuts!
