Edge AI Balcony Guard detects visiting pigeons locally and sweeps a water gun to drive them away. It is designed to deter pigeons without a camera and without harming them, helping prevent droppings on balconies.

Creator Hiroshi Nakata built it with Arduino, a servo, and Solist-AI, and published it on ProtoPedia on September 23, 2026.

OVODYO displays time by rotating two numbered 12-sided solids until the appropriate faces point upward. One indicates the hour and the other advances in five-minute intervals, with internal gearing rotating each shell around two axes.

Creator ekaggrat singh kalsi built the clock. Because the minute solid only changes every five minutes, LEDs indicate the exact minute between those steps.

A Rube Goldberg machine sends balls, levers and other mechanisms through a long chain reaction before a wooden hand finally pulls down a jacket zipper. After all of the staged motion, the final task is simply opening the zipper on a piece of clothing.

The machine was created by Steven Price of Sprice Machines, a builder specializing in chain-reaction contraptions.

A homemade alarm clock gives the sleeper five seconds to stop the alarm before a loaded banknote is fed into a shredder. Instead of merely continuing to make noise, the device makes oversleeping carry a physical monetary consequence.

The Arduino-based build was published by the Japanese maker channel Mechatro on September 12, 2026.

M5Flick is an input interface that lets users type Japanese by punching a cushion while wearing a red glove. Instead of flicking a phone screen with a finger, the user turns full-body motions into text input, including moves styled after a Shoryuken uppercut.

Creator Hatake / Furukawa built it with M5Stack and UnitV2 hardware, combining text entry with a stress-relief punching interface.

Hardwired to Destroy Itself combines a one-hertz timing circuit with a motor-driven drill so that operation periodically damages components on its own protoboard. A 555 timer provides the 1 Hz signal while a synchronized DC motor rotates the mechanism that brings the drill bit into the circuit.

The machine is built largely from scrap wood, recycled cardboard, and a motor salvaged from an old printer. Creator bornach made it for Hackaday.io's One Hertz Challenge.

A robot with rows of suction cups arranged like tracks can stay attached while driving from walls onto ceilings. As it moves, cups at the front attach one after another while those at the rear peel away in sequence.

The passive cups maintain adhesion without a vacuum pump. The robot traveled on glass, wood, metal and painted surfaces, and the roughly 3.5 kg machine also climbed while towing a 7.94 kg payload. The work was carried out by University of Michigan researchers Andrew Nguyen, Mingyuan Li and Daniel Bruder.

Cookie Dunker keeps the cookie fixed in place and electrically raises the glass of milk to meet it. An infrared remote shaped like a milk carton controls a 3D-printed scissor lift, slowly lifting the glass until the milk reaches the waiting cookie.

A linear actuator drives the lift. Creator Chanyanuch Charoensuk describes the project as inspired by Chindogu and deliberate over-engineering.

T1 is a robot that can transform itself between humanoid and robot-dog forms. It normally moves upright using two legs and wheels; when it reaches a step, it transforms into a quadruped, crosses the obstacle on four legs, and then stands back up as a humanoid.

The robot is about one meter tall and weighs roughly 16 kg. It was developed by China's Qiyuan Robotics and went on sale from 19,999 yuan, with shipments scheduled from October 1.

AeRove is a compact drone that turns the guards surrounding its propellers in flight into wheels after landing, allowing it to roll along pipelines. It normally travels on the pipe and takes off only when it needs to hop over an obstacle.

A spring-loaded mechanism switches between flight and ground configurations in about 200 milliseconds. The researchers report roughly 14 times lower current draw while rolling than during continuous flight, and demonstrated straight and curved traversal, obstacle hopping, and simulated leak-marker detection on a 51 cm steel pipe. It was developed by NJIT researchers Caleb Polillio and Petras Swissler.

Franky Candy Dispenser releases candy from a Frankenstein monster's mouth when you press the glowing brain on top of its head. While waiting, its LED eyes blink and look around; pressing the button also triggers spoken lines, sometimes including a reminder to brush your teeth.

Inside the head, a servo-driven 3D-printed Archimedes screw carries the candy to the mouth. The glowing brain is built into a large 100 mm arcade button. The project was created by Adafruit's Ruiz Brothers and Liz Clark.

Tongari Shot is a shooting device that actually launches cone-shaped corn snacks worn on a fingertip using compressed air. The results are recorded as a score, turning the snack launcher into a game.

The firing system uses an air compressor and air valves, with an M5Stack Core2 and servo motors among the control hardware. RacoonFactory created it from the idea that the fingertip snack looked as if it could really be fired.
