Nick Bild built the µTari Go, a handheld Atari 2600 that uses the original console's circuitry rather than emulation. It has a built-in four-inch CRT, controls, speaker and a slot for original Atari 2600 cartridges.

The components fit inside a 3D-printed enclosure. The device uses an external 12-volt power supply rather than an internal battery.

In a study announced in 2025, researchers described a thin electronic tattoo that sticks to the forehead to estimate mental workload. Its sensors read electrical activity from the brain and eye movements, while a small battery pack enables wireless use.

The sensors are customized to fit each person's facial features. In tests with six people doing memory tasks of increasing difficulty, brainwave patterns changed as mental demands rose.

The work comes from researchers at the University of Texas at Austin and collaborators.

The Brass Thumb Pomodoro is a steampunk-style desk timer that rewards a completed 25-minute work session by popping a thumbs-up figure out of its case. A side switch selects work or rest mode, with five-minute breaks between sessions.

Maker Krzysztof Jamroz built the USB-powered device with Arduino electronics and 3D-printed parts. Assembly instructions and code are available on GitHub.

A maker has built a way to play video games using ordinary VHS videotapes and a VCR.

The tape stores not just prerecorded pictures but also information needed for the game. When the tape plays, pressing buttons on a controller changes what appears on screen. Demos include Super Mario Bros. backgrounds and a Doom-style game.

Creator Throaty Mumbo uses custom electronics to read the video and game information from the tape.

KeyboaStick is a 3D-printed mechanism that replaces the W, A, S and D keycaps with parts linked to a small joystick. Tilting the stick presses the corresponding keyboard keys through articulated linkages.

Created by Korean maker FunOrNothing, the design uses mostly print-in-place joints. A Make: editor tested it by playing Sonic the Hedgehog 2 with the modified keyboard.

Meshbot was built to carry a Meshtastic radio up a steel drainpipe on an apartment building. Nearby buildings made radio reception poor, and its creator couldn't access the roof to put an antenna higher up.

Robert Wallhead made a modular climbing robot using magnets and 3D-printable chassis parts. He describes the results as working reasonably well, while acknowledging it was hardly the most practical solution.

A port of Super Mario 64 lets Microsoft's 2009 Zune HD music player run the Nintendo 64 game. It supports on-screen touch controls, sound and saving, and the creator says it runs mostly at full speed.

Developer rsheldiii published the project on GitHub. It doesn't distribute the game itself; users must supply a ROM dumped from their own cartridge to build it.

Sherobo looks like a round watermelon, then unfolds four legs and walks. It was designed around the Japanese watermelon-splitting game, with a watermelon-shaped robot that can flee on foot rather than sit still for a hit.

Creator Ryota Kobayashi built the 12-degree-of-freedom quadruped with a folding linkage mechanism that lets it return to a spherical shape. The project page includes build instructions and pictures of the transformation.

The Snack Safe is a lockable container for treats that won't open until you've walked a set distance. To get to the food inside, you first have to earn access by walking.

Matty Benedetto of Unnecessary Inventions built the device around a pedometer-controlled locking mechanism and introduced it on his invention website.

A children's Anpanman ride-on toy has been rebuilt as a motorized moped intended for public roads. The tiny vehicle was fitted with propulsion, brakes, lights and turn signals, and its creators say it received a license plate.

The maker, Kounotori DIY, documented the build in a YouTube video titled '魔改造アンパンマンバイクで公道を爆走してみた！！'.

A new tool improves tide predictions on the Casio G-SHOCK GBX-100 without changing its firmware. In Saint-Malo, France, the watch's original data produced average high- and low-tide timing errors of 29 minutes, with a worst case of two hours and five minutes.

Creator Matthieu Girard found that the watch can calculate tides using 60 harmonic constituents, but the official app supplied only a small four-constituent set for Saint-Malo. He calculated a fuller set from official measurements and transferred it via Bluetooth. Average error against 2025 observations fell to five minutes.

To reduce the temptation to pick up his smartphone, Kevin Noki built a large handset styled after a 1980s mobile phone. It is not a standalone cellular phone: it connects to an existing smartphone via Bluetooth to handle calls.

After an initial Bluetooth setup produced poor audio, Noki switched to a dedicated hands-free module. He shaped a foam mockup before 3D-printing the final enclosure, allowing the real phone to stay out of his hands during calls.
