Clockwork Pi PicoCalc – DIY handheld powered by Raspberry Pi Pico. Retro 4″ IPS screen, backlit QWERTY keyboard, dual speakers, SD storage, open-source, perfect for BASIC, Lisp, Fuzix, and firmware development. The PicoCalc brings the charm of the golden age of computing into the modern world—combining nostalgic design with hackable flexibility. It’s a compact, card-sized handheld device built around a Raspberry Pi Pico (or Pico W / Pico 2) microcontroller, mounted on a custom ClockworkPi v2.0 mainboard. Think of it as an evolution of the classic pocket computer—but upgraded for today’s maker and coding enthusiast. Retro inspiration, modern power: A rubber QWERTY keyboard under a vibrant 4-inch, 320×320 IPS display brings tactile input and sharp visuals in one stylish package. Expandable and open by design: Includes 8 MB PSRAM, full-size SD card slot, dual speakers, USB-C (charging/debug), audio jack, and exposed GPIO for creative expansion. Software support: Comes preloaded with interactive tools like BASIC and Lisp, a Fuzix UNIX-like environment, and even MP3 playback. Plus, you can develop using C/C , MicroPython, Rust, Lua, Golang, and more via supported SDKs and IDEs. Lightweight DIY-ready build: All housed in a high-quality ABS enclosure with tempered glass. A 2.5 mm hex key is included for easy assembly—or disassembly if you’re hacking it.
