A cyberdeck is a homemade portable computer in the cyberpunk mold (exposed, utilitarian, built to suit its maker rather than to sell) and NickZero's Ultra Minimal Cyberdeck [instructables.com] is exemplary: just a single-board computer, a tiny keyboard (cf. my "Cormac" board, useful only for writing novels by Cormac McCarthy), a small screen, and a battery laced together inside a 3D-printed shell.
Fairly easy to put together, some soldering skills needed to put the keyboard kit together and wire up the charging circuit.
every component is an off-the-shelf thinger, so the work is mostly wiring rather than engineering. The keyboard is a 30% layout — thirty keys, no number row, no function row! — sized to roughly the width of the display, which gives the closed device a clean rectangular footprint. The only big deal is you'll need a 3D printer for the case, and one with a 20cm-square bed at that. You have questions? Not with this keyboard you don't.
The parts: a Raspberry Pi Zero 2W [thepihut.com] with a 16GB-or-larger SD card; a Waveshare 7" touch display kit [waveshare.com]; an Adafruit PowerBoost 1000 charger [adafruit.com] with a 4000mAh LiPo cell; and a Gherkin 30% keyboard kit [mechboards.co.uk], which needs thirty switches and keycaps of your choosing. Two right-angle USB-C-to-USB-A cables and a small slide switch finish the wiring.
