A Nico Nico Douga maker named Korori built a triangular machine for the anything-goes JCJC time-attack scene. The idea targets one of the course's hardest sections, the lane change, where roller contact can slow or destabilize a conventional rectangular chassis.
By making the body triangular, the design aims to reduce that contact near the crest. In the pursuit of speed, even the familiar shape—and effectively the usual four-wheel assumptions—of a Mini 4WD car are treated as optional.
Optimization gets wonderfully ruthless when “make the Mini 4WD faster” turns into “the rectangle is optional, and apparently four wheels are too.”
Camera with Digital Film lets you physically pull the captured image out of the camera as a cartridge. A Raspberry Pi 3 A+ and 5 MP camera write each shot to a removable module containing a 1.54-inch four-color e-paper display.
The cartridge can then be displayed as a physical photograph. Because it is e-paper, the image remains visible without power and can later be overwritten. Modern digital hardware brings back one very specific analog pleasure: taking the picture out of the camera.
Digital cameras spent years eliminating film, and now the joy of pulling the picture out has come back around. A very elegant detour.
To push 3D printing down to roughly 150 µm scale, a microscopic printer was built that shines a 405 nm laser through the tip of an optical fiber and cures resin point by point. Created by Diffraction Limited, it moves the illuminated point much like an FDM printer moves its nozzle.
To improve resolution further, the resin is mixed with curcumin from turmeric as a UV absorber. The result includes a Benchy just 150 µm long and a Stanford Bunny that appears smaller than a human hair.
Push microfabrication far enough and turmeric somehow joins the materials team. That's an unexpectedly kitchen-adjacent breakthrough.
If an alarm sound is not enough, why not have the clock play a 720×720 video when it's time to wake up? The Video Alarm Clock uses an ESP32-P4-based Waveshare module and can store plenty of clips on an SD card.
The futuristic part comes with some very old-fashioned requirements: AVI with MJPEG and PCM, plus classic 8.3 filenames. The display feels modern; preparing the files suddenly feels like an earlier era of computing.
It's a video alarm clock from the future, quietly asking you to respect 8.3 filenames in the background. Nice little time warp.
Robot mowers often struggle to trim right up against walls and lawn boundaries. The H510 Pro tackles that limitation with a mechanical arm that moves its main cutting disc outward by about 7.4 cm. The system was shown at IFA 2026.
EdgeSense identifies different boundary types, and when needed the mower physically reaches the blade toward the edge. Side guards and people-and-animal detection handle safety while the machine solves the last few centimeters of mowing in an unusually literal way.
Can't quite reach the edge? Extend the blade on an arm. It's such a wonderfully direct answer to a tiny geometric problem.
