Another month has gone by, so it’s time to gather together everything I’ve written for digital publication over the past four-or-so-weeks.
It’s been a busy February, and a day longer than usual to boot, but if I had to pick some personal highlights they’d include this dual-display sunlight-readable PDA build, a tiny $5 mechanical keyboard, Paul Krizak’s amazing Wire Wrap Odyssey microcomputer, an anonymously-published 6,000 PPI boardview of the Nintendo Switch Lite, Wojciech Graj’s audio-only Doom port, and Tankgrrl’s Commodore 1541-style housing for a USB floppy drive.
