Acceleration controlled cat ears for our FRC driver ;)
What is this?
kitty kaan is a wearable pair of motorized cat ears designed for our FRC driver. The ears react to acceleration, making them move with the driver in a more expressive way.
The project combines a small electronics stack and compact mounting hardware into a lightweight assembly. An accelerometer detects motion, and the control electronics translate that movement into ear movement. The result is a simple but very silly accessory that gives the driver a pair of responsive “kitty ears.”
This was designed as a small CAD and electronics integration project. A big part of the challenge was packaging everything into the smallest form factor possible while still keeping the assembly buildable. Instead of using one large controller board, the electronics were split across smaller breakout boards so they could fit into tighter spaces and be arranged more flexibly.
Renders
Some context
Its a simpler project for a simple idea.
The goal was to make the electronics stack as small as physically possible, which is why seperate breakouts were used. They also added to the simplicity of the design (which is nice).
Fitting everything together was the hardest part of this mini project, but it turned out looking pretty awesome!

Questions
How big is the Cattitude PCB?
It measures 35 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cattitude use?
14 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Cattitude KiCad files?
From the SharKingStudios/kitty-kaan repository on GitHub, at the commit this page was made from: the board is PCB/Cattitude.kicad_pcb and its schematic PCB/Cattitude.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cattitude design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
