![]() ![]() Each disc has a series of concentric cam slots to drive followers that flip the red segments in and out of view. The trick lies in a synchronized pair of rotating discs, one for the top four segments and another for the bottom three segments. The latest of is a mechanical seven-segment from a master of 3D printed mechanisms,, and can use a single motor to cycle through all ten possible numbers. Seven-segment displays have been around for a long time, and there is a seemingly endless number of ways to build them. Continue reading “The Incredible Mechanical Artistry Of François Junod” → Posted in Art Tagged automata, automaton, mechanics, Mechanisms If you don’t quite have the time and fabrication skills, you can still create mesmerizing automatons with 3D printing like. ![]() Some builds, like ’s flightless drone aren’t quite as complex, but are no less inspiring. Very few people have the time, skill and patience to make these creations, but we are glad there are still a few around. He also collaborates with craftsman like jewelers on works like La Fée Ondine, which we thought was CGI when we first saw it in the video after the break. Many of them also include their own soundtrack, which range from simple bells and chimes to complete melodies from mechanized wind instruments, as demonstrated in Le Champignonneur below. The mechanics of the automata are part of the display, and contain a vast array of gears, linkages, belts and tracks. ’ creations are all completely devoid of electronics, and are powered either by wound-up springs or weights. is one of these masters, and the craftsmanship and intricacy on display in his automata is absolutely amazing. The art of building purely mechanical automatons has dramatically declined with the arrival of electronics over the past century, but there are still a few craftsmen who keep the art form alive. If you’re into weather displays, you’re in luck: we’ve featured many different styles over the years, including e-paper screens, analog gauges, split-flap displays and even a miniature recreation of the local weather.Ĭontinue reading “3D Printed Mechanical Contraption Shows Live Weather Forecast” → Posted in Misc Hacks Tagged Arduino MKR, automaton, weather display The heavy work is performed by stepper motors and servos, while micro-switches and optical detectors determine the end point of each movement. This then drives the mechanical system through a pair of motor driver ICs. Live weather data is fetched through an open weather API by an Arduino MKR WiFi 1010. We especially like the system that folds out rays of sunshine from behind the cloud you can see it working in the video embedded below. These symbols are moved around by dozens of gears, levers, swinging arms and other moving parts which were all 3D printed. It uses brightly coloured indicators inspired by the BBC’s famous “fluffy cloud” symbols that can show various combinations of sunshine, clouds, rain and snow. Nowadays you simply need to glance at your phone to know whether you need to pack an umbrella, but where’s the fun in that? Why not have a huge mechanical display to show you a summary of today’s weather?Īs a fan of automatons and other contraptions filled with gears and pulleys, decided to build just such a machine for his latest Mikey Makes video. “What’s the weather going to be like today?” is a question that’s near-permanently on the mind of those living in places like Britain, where brilliant sunshine can follow thick clouds, only to turn into drizzle an hour later. ![]()
