Telegraphs were once the fastest way to send messages over a distance. While they’re long since obsolete, DIYprojects decided to build a modern take on the paper strip telegraph, using an Arduino Mini, a motor, wood, and a pen to write down text messages. Build guide here.
THE BEST Machines
In this promotional spot for CAD/CAM software developer Open Mind, they demonstrate how a 5-axis CNC mill can transform a solid block of metal into a replica of a basketball net, by gradually carving away bits of metal until only a woven net remains. Skip to 1:06.
Designed by Shunji Yamanaka for the Future Robotics Technology Center, this incredible work of mechanical engineering can transform between walking, rolling, and spinning, and even climbs stairs. The robot was designed as a study for potential future vehicles. More here.
While it’s unlikely to be approved for use in an actual casino, Berthil van Beek’s motorized LEGO Technic roulette wheel is an impressive build. It’s designed to work as part of a larger great ball contraption, but is perfectly awesome all on its own. Ladies and gentlemen, place your bets!
Have you ever gotten a box from Amazon that’s way too big for the item packed inside? The CMC Cartonwrap 1000 solves this problem by scanning the item to be packed inside, then making a custom-sized box for it. It’s not ideal for fragile items, though it looks like they’re working on that.
The aptly-named Brick Experiment Channel decided to see if they could make a paper shredder using only LEGO components. While the motor and gearing was pretty simple to set up at first, getting Technic gears to actually shred paper took some serious experimentation.
Machine shop DataPro shares hypnotic time-lapse footage of a Datron CNC milling machine, as it takes a disc of aluminum and transforms it into a precise and smoothly formed gear. It was shot as a time-lapse, but won’t it be awesome when machines can do this in real time?
We’ve seen industrial machines that can bend wires into shapes, but thanks to 3D printing and low-cost controllers like Arduino, you can make your own desktop machine now. How to Mechatronics shows us exactly how. Grab the full instructions, models, code, and schematics here.
Martin Molin is known for his amazing music-making marble machine. He’s been working on an even more complicated machine for years, and has been documenting the build. This conveyor belt assembly is one of the more enthralling parts he’s completed so far.
Hypnotic video footage of a rocket propellant tank being made by wrapping and weaving layers of carbon composite filament around an aluminum form. The custom-built machine and software were engineered by the literal rocket scientists at Interorbital Systems.
One of the more impressive LEGO Great Ball Contraptions we’ve seen turned up at Japan Brickfest 2018. Among its contributors was Akiyuky, whose modules wowed the crowd with all manner of hypnotically moving parts, while his LEGO Technic railway shuttled balls alongside.
Tearing down LEGO buildings usually requires plucking bricks off by hand. But Shadow Elenter’s approach is way cooler. He built a crane to do his demolition, using LEGO Technic parts and 18 motors. It can lift items, knock them down, and claw or break them apart.
Heads or Tales Coins & Collectibles presents a wonderfully satisfying video showing a laser etching machine making a cold storage coin – a physical manifestation of cryptocurrency. These coins feature a unique private key which can be used to unlock its bearer’s Bitcoins.
A mesmerizing look at a machine designed for the high-speed production of paper cups. It starts out with flat sheets of paper, rolls them onto a form, glues the seam, then adds the bottom, and eventually rolls the top edge, cranking out as many as 130 cups per minute.
A look inside the P. van der Wegen Gear factory, where they make enormous gears for mining applications. While the process of milling these massive parts is truly fascinating, we can only imagine what they look like when in use in the machinery they’re destined for.
