DIY Handheld PC Makes Room for Analog Doodles and Sticky Notes

Pocket-sized computers are everywhere, but they often come with a catch: you’re stuck tapping away at a glass screen, missing the tactile satisfaction of real keys or a quick scribble on paper. For those who crave a bit more hands-on interaction, the latest DIY handheld PC, dubbed KeyMO, offers a playful twist by making space for both digital work and good old analog notes.

There’s something deeply satisfying about typing on physical keys, especially if you spend lots of time coding, writing, or just prefer that clicky feedback. While there are plenty of gadgets trying to bring back the compact QWERTY experience, few go as far as the KeyMO. This project, powered by a Raspberry Pi, combines a touchscreen, a compact Bluetooth keyboard, and a surprise addition: a handy spot for sticky notes and handwritten sketches.

Unlike many handheld devices that force you to choose between typing and tapping, KeyMO gives you both. The 4-inch touchscreen handles browsing and touch commands, while the physical keyboard is perfect for speedier and more accurate typing. It feels like a mini-laptop that can still slip into your bag, ready to be pulled out for a quick coding session or a burst of inspiration.

What really sets KeyMO apart is its use of space. Most makers would be tempted to cram every millimeter with more tech, but here, the extra room becomes a sanctuary for analog creativity. There’s a dedicated patch next to the screen for sticky notes, so you can jot down reminders or sketch diagrams on the fly—no need to switch apps or lose your train of thought. Plus, a neat slot holds your favorite pen, making the transition from typing to doodling seamless.

The enclosure is entirely 3D-printed, giving tinkerers and makers the freedom to tweak and personalize their own KeyMO build. Off-the-shelf components mean you can put this project together without hunting for rare parts or breaking the bank. The Raspberry Pi inside runs a full Linux OS, letting you go beyond the limits of mobile platforms and get real work done wherever you are.

KeyMO might look like a quirky cyberdeck from a sci-fi movie, but its blend of digital power and paper practicality is all about making things friendlier and more flexible. For gadget lovers who want the best of both worlds, a device to tap, type, and scribble, this little handheld packs plenty of personality into every inch.
