Nicholas LaBonte made a handheld computer called the Cyberdeck Handheld, which combines cyberpunk and nautical aesthetics, as well as a keyboard with a custom PCB with tactile switches and an ATmega32U4 running QMK firmware.
It uses a Raspberry Pi and an RTL-SDR, with a hardwood back, a bronze heat sink for the Raspberry Pi, a red PSP joystick for mouse input, and a customised keyboard made from a polymer sheet with a faux-aluminium look and engraved symbols as tabs.
It also has a power button and charging port, with internal connections to USB ports, the keyboard and SDR.
LaBonte would like to improve the device’s bronze heat sink, with extra shielding for the SDR and less noise from the keyboard, and add a camera, GPS receiver or 4G modem.
