Before We Begin
🐄 Because Tomorrow is Eid... 🎉 I couldn't just commit code — I had to commit to a cow.
While you're deploying apps, I'm deploying livestock. While you're pushing to main, I'm pushing hay to a very judgmental bovine.
Yes, tomorrow is Eid, and I bought a cow. And not just any cow — this one moo-ved my heart and inspired my repo structure.
Now featuring:
CAD files shaped like beefy dreams 🛠️
Rotary encoders spinning faster than uncles after 3 cups of Eid tea ☕
More moo than you can git pull 🐄
| Feature | Fusion 360 CAD | Cow | Reality Check |
|---|---|---|---|
| Shape | Perfectly parametric, clean curves | Curves? More like squiggles & wobbles | Fusion 360 tries to model squiggles; cow just wobbles for fun! |
| Behavior | Obeys every command, no complaints | Randomly moos, eats grass, naps a lot | Cow wins in chill vibes; Fusion 360 wins in “do what I say.” |
| Flexibility | Can stretch or compress with a click | Stretches? Only when someone calls dinner time | CAD models obey physics; cows obey hunger. |
| Sound | Silent unless you count your keyboard | Loud moos, occasional tail swishes | Sorry Fusion 360, cows have better volume control. |
| Energy consumption | Requires electricity & caffeine | Eats grass, naps, and still looks majestic | Cow is the original eco-friendly machine. |
| Rotary involvement | Rotates perfectly on digital axes | Tail rotates randomly, usually to swat flies | Cow’s rotary = natural antenna; CAD rotary = pure precision. |
Stretch Goals (because why not?) Design a cow-shaped Eid lantern with Fusion 360 — because everyone needs a glowing moo at night.
Create a rotary encoder that controls the volume of a virtual cow’s moo. Extra points for adding echo! 🐄🎶
Animate a Fusion 360 model that “stretches” like a cow trying to reach the last bite of grass.

Questions
How big is the HAMBA PAD PCB?
It measures 60.5 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HAMBA PAD use?
10 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 HAMBA PAD KiCad files?
From the samdoes-stuff/HAMBA-PAD repository on GitHub, at the commit this page was made from: the board is PCB/Hambapad.kicad_pcb and its schematic PCB/Hambapad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HAMBA PAD design in my own project?
Its repository states no licence, so its author keeps all rights: ask samdoes-stuff before reusing the design.
