Inspired by Riskable's Void switch and keyboard, Alexandre Moatty aka heiso/ezotsu shared his Macrolev, an open-source analog keyboard with web-based configurator.

I use the two prototypes shown above as my daily drivers for both coding and gaming. They work well, and the current state of the web configurator is sufficient for seamlessly switching between coding and gaming modes – ezotsu.

Features

• analog input: keys detect varying levels of pressure (Hall effect)
• rapid trigger: actuation without full release (faster response times)
• continuous rapid trigger: automatic repeated key
• tap and hold functionality
• web-based configurator

Specs

• 66 keys, horizontal staggering
• magnetic switches
• STM32F411CEU6
• CD74HC4067SM multiplexers
• 3D-printed case
