Adrian wanted to create a silly surprise for their friend and avid player of the rhythm game OSU!, with the bonus goal of getting a chance to learn about electronics. The result of this was an adorable two-key keyboard based around a Teensy.

Combining some spare keyboard switches and a 3d-printed case and caps with Teensy’s built-in Human Interface Device (HID) mode, the gag gift gives off a surprisingly professional vibe, not to mention a fair number of laughs. Despite being intended as a joke, the keyboard could be useful for video editing, or … using Stack Overflow!
