Personally, I love it because it reminds me of that bizarre scene in early music videos where Kelly Rowland from Destiny’s Child was sending texts using Excel spreadsheets on a handheld device that looks very similar.

Expanding Our Vocabulary

Penk’s project post also taught us a new word: orthogonal. It relates to keyboards, meaning all keys are aligned in rows and columns, like a grid. This is an orthogonal keyboard.The Kailh Low Profile Choc V1 mechanical switches provide a retro clicky sound and feel to the keyboard, powered by an Arduino Pro Micro microcontroller board.

Super Simple Design

Penkēsu is very simple, containing only three hardware components within the 3D printed shell. Everything is open-source and can be found on GitHub, as Penk shared a step-by-step guide so you can build it yourself. http://penkesu.computer/

This manufacturer also developed CutiePi, a portable tablet built around the Raspberry Pi Compute Module 4.
