RaphCoder13’s Birdy44 Is a 3D-Printable, RP2040-Powered Mechanical Keyboard with Shock Trackpads

Pseudonymous ergonomic keyboard fanatic “RaphCoder13,” hereafter merely “Raph,” has designed a 3D-printable open supply cut up keyboard powered by a pair of Raspberry Pi RP2040 microcontrollers — and boasting matching trackpads for either side.

“Birdy44 [is] a low-profile 3D-printed and hand-wired cut up keyboard,” Raph explains of his creation — completed in eye-catching crimson, black, and white. “All elements have been printed in PLA, 0.2mm layer top. The instances and tenting legs have magnets inserts: 4× 8×2mm for every case and a pair of× 8×3mm for every tenting leg. Add pause throughout printing to insert the magnets (at 2.60mm for the instances and three.40mm for the legs). A comfortable match and a 0.2mm high chamfer keep away from the magnets to be pulled off by the printing head.”

Raph’s personal model of the Birdy44 is constructed utilizing 44 Kailh Choc V1 mechanical keyboard switches with customized legend-free low-profile keycaps. Inside every half of the keyboard, which join collectively utilizing a tip-ring-ring-sleeve (TRSS) cable, is a Waveshare RP2040-Zero microcontroller board to behave because the keyboard controller plus diodes for every change. There is no PCB, although: either side of the keyboard are hand-wired, somewhat than assembled on a circuit board.

The keyboard’s not only a textual content entry gadget, although: each halves embrace a 40mm Cirque Trackpad, serving as a pointing gadget or as a management floor for a customized enter. These are positioned in order to be the inner-most a part of each keyboard sides — permitting for, must you want, DJ-like deck-spinning operations once you carry your palms from the keys.

The 3D-printed chassis consists of magnetized tenting legs, permitting the angle of the keyboard to be adjusted, and there is a carry case for taking it on-the-go. “I supposed to make use of magnet to maintain the halves within the transport case,” Raph explains. “The instances have cavities to insert 10×3×2[mm] magnets. It show to be not highly effective sufficient to maintain the halves in place, therefore I went for 10mm elastic tape Both strive utilizing greater magnets or do not trouble with these.”
