Big Enter Key (keyboard)

Who loves pointless yet cool gadgets?

The Big Enter!

Here's a truly useless but attractive plastic part. With the appropriate electronics, the button is fully functional!

Thanks to the unique, self-developed design, the button's mechanics function perfectly. Even if not pressed in the center, the cap moves downwards parallel!

Size: 83x63x21mm!

I use these keyboard buttons as switches: https://de.aliexpress.com/item/1005002099759942.html (the cap fits the “dust proof” version of the switches!)

For the electronics, I use the Raspberry PI Pico (Waveshare PI Zero RP2040, USB-C connection) This board is very inexpensive and fits into the housing.

The Arduino Keyboard Library works very well with the RP2040. The sample project can be used almost 1:1.

Have fun building it. Post pictures in the comments if possible!
