Jonathan turned the programming board game Robot Turtles into a version played with a real robot. A secondhand Dash robot moves across an alphabet foam-mat grid that serves as the physical game board.

NFC tags are attached to cards from the original game. Scanning them on a custom reader sends commands such as forward, left and right to the robot, and players can queue a sequence before running it.

Shintaro Tamefusa built a rig that makes a cold croquette appear piping hot: as he pulls it apart with both hands, he steps on a foot pump and sends smoke through a tube behind the food.

Smoke from a smoke machine is stored in a sealed container and pushed through the tube by the foot pump. When he compared the effect with an actually heated croquette, the real one was painfully hot but produced barely visible steam, while the cold croquette with added smoke looked much hotter.

LOOK MUM NO COMPUTER's Furby Organ turns 44 Furby toys into a playable musical instrument controlled from a keyboard.

The video demonstrates the group being controlled to change pitch and vocal sounds, and also shows the extensive wiring and modified toys behind the build. The creator describes it as a project that took many hours to complete.

Joseph's Machines recreated the morning contraption from Wallace & Gromit: The Wrong Trousers as a real physical machine.

The build lifts a bed to drop its occupant into clothing, continues the dressing routine, and finally launches jam toward toast popping from a toaster. The video shows not only the finished sequence but also the process of working through dangerous stunts, sticky jam problems and training a dog for the scene.

BANDAI SPIRITS' Mobile Stationery Automatic Transforming Business Card Case unfolds automatically when pointed toward someone and activated with a button, rotating the stored card 180 degrees and presenting it to the recipient.

GIGAZINE's hands-on review shows the full sequence from the closed case to the presented card. An ordinary business-card exchange has been automated with a mechanism that behaves more like a transforming toy.

Nemo Gould's Chatbot is a mechanical robot modeled on a chatbot, assembled from an old radio cabinet, an ammeter case, camera bellows, gears, motors, LEDs and other salvaged parts.

Gould describes it as combining the capabilities of an AI chatbot with the subtle condescension and gentle deflection associated with human customer-service agents.

Maker gangi-man 3D-printed an assassin's teapot, a vessel that can pour two different drinks from the same spout. It has separate internal chambers, and covering one of two air holes in the handle determines which liquid flows out.

The maker aimed for a design suitable for everyday use and spent about 14 hours printing it. After tackling leaks around an acrylic lid, the finished teapot successfully dispensed Calpis Soda and Amino Supli separately.

A child was frightened of the family's robot vacuum and would turn it off whenever it started moving. To help the two get along, the maker fitted the vacuum with a motorized tail, inspired by the child's love of cats.

A servo pulls fishing line to bend the tail, with randomized speed and angles to make it feel more lifelike. The tail alone did not hold the child's attention for long, so the maker also added a fluffy cover. The child began petting the vacuum and offering it stuffed animals.

Daniel Simu, creator of the full-size acrobatic robot Acrobot, has built a miniature version called Micro Acrobot. The desk toy combines MakerBeamXS aluminum profiles, 3D-printed parts and an acrylic panel, and is offered as a DIY kit.

It has the same number of joints and the same hands and feet as its larger counterpart, so it can be posed for similar tricks, including handstands. Unlike the large robot, the miniature has no motors and must be posed by hand.

ESP-Vim runs Vim 9.2 directly as firmware on ESP32-S3 and ESP32-P4 microcontrollers, without Linux or another operating system underneath. On a board with a display and keyboard, it becomes a small computer dedicated to editing text.

Beyond editing files, it includes Git, MicroPython, SCP/SFTP and a web interface accessible from Vim. The project currently reports testing the ESP32-P4 and ESP32-S3 in an emulator; physical boards have not yet been tested.

A playing card fitted with a small vibration motor can remain attached to a ceiling without glue or a suction cup.

As the flexible card vibrates, air is pushed out of the tiny gap between it and the rigid surface, lowering the pressure and creating adhesion. Steve Mould also experiments with larger vibrating setups, reaching loads of several tens of kilograms.

GB Test Lab is a diagnostic cartridge for the original Game Boy. It checks functions including memory, interrupts, cartridge-slot lines and button contacts, while its Quick Check runs several autonomous tests in under a minute.

Results can be stored per console, and a connected Game Boy Printer can produce a six-page report on thermal paper. The cartridge also contains twenty reference articles explaining Game Boy components and symptoms.
