As impressive as large-scale milling machines can be, compact machines that can create intricate parts are equally fascinating to us. In this clip, Bantam Tools shows off their Desktop PCB Milling Machine as it carves a miniature topographic map of Washington’s Mount Rainier out of a cube of aluminum.
THE BEST Machines
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?
Because he was hungry, Sprice Machines built a ridiculously complicated chain-reaction machine that’s designed solely for dunking a cookie in milk. It doesn’t even do a good job doing that, but it’s entertaining to watch it get there. Stick around for lots of trial and error footage.
With hoarding surrounding the COVID-19 pandemic, there’s been quite the run on toilet paper here in the U.S. While add-on bidet toilet seats are always an option, Mike of Useless Duck Company thinks he’s got a more thorough solution – though his approach might be just a little more painful. Kids, don’t try this at home.
While it’s not as powerful or accurate as Mark Rober’s motorized playing card thrower, Brick Experiment Channel’s version is still pretty sweet, and was built entirely using LEGO components, giving it double the geek cred. Now we want him to build a version that fires cash… or minifigs.
RC model fan Bordin Luca shows off a massive LEGO Technic build based on Jeroen Ottens‘ design for a Liebherr LTM 11200 construction crane. The nearly 8000-piece model features motorized support legs, and a huge, extendable tower. It’s featured alongside several other large RC vehicles in the eBook Bigscale RC Model.
Electron Dust shows off a nifty machine that can bounce a ping pong ball, while keeping it balanced and centered on its moving platform. It uses combination of open-source image processing software and Arduino-controlled stepper motors to work its magic. More build details here.
LEGO Technic machine expert The Brick Wall created an amazing working sawmill that turns long logs into individual pieces of firewood. The wood is delivered on the back of a LEGO truck, then the factory cuts the wood into smaller logs, then splits them into quarters, ready for lighting.
Prima Power shows off the power and speed of one of its impressive fiber lasers. Their 6kW Laser Genius slices through sheet metal of varying thickness like a hot, razor-sharp knife through butter. We can’t believe how easily it got through that metal at 1:20. More laser porn here.
This footage from Chinese company Jiake Machine shows the process of taking coiled wire and transforming it into a sturdy mesh for fences or construction. The automated system pulls wires from dozens of spools, and feeds them through a massive welding rig that spot welds each intersection, with the mesh emerging from the other side.
There are professional card throwers out there who can land a playing card on its edge every time. But if you don’t possess those skills, you could always build a mechanical solution, like The Practical Engineer did. His motorized launcher can fire playing cards at speeds nearing 200km/h (or about 124 mph).
We’re surprised that LEGO machine expert JK Brickworks has never built a Great Ball Contraption module before, but his first one definitely lives up to his standards. Watch as four tiny LEGO robots work along an assembly line, each passing a ball to the next to move it down the line. It also appears to work as a hypnosis device.
While it’s not likely 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!
It may not play music like Wintergatan’s marble-powered musical instrument, but we still enjoyed listening to the soothing sounds and watching the hypnotic movements of this wooden marble machine, which serves as an example of the modules you can buy from its creator.
Guinness World Records introduces us to animatronics and robotics expert Matt Denton, and his prize-winning walking robot, Mantis. This gigantic, diesel-powered hexapod weighs in at nearly 4200 pounds, and can stomp around while an operator rides in its mid-section. Matt also happens to be the co-creator of BB-8.
As long as we’re not carrying a heavy suitcase, we generally take the stairs when given a choice. But for those times when you feel like giving your legs a break, the escalator is quite the invention. Jared Owen provides an animated explanation of the inner workings of this engineering marvel that dates back to the mid-19th century.
It might spill a little food along the way, but Joseph’s Machines‘ ridiculous Rube Goldberg contraption does ultimately perform the task it’s intended for, feeding him a tasty meal of peas, potatoes, asparagus, and chicken, along with a cupcake and a nice cup of coffee, all without getting up from his desk.
The Q takes a gamble with this build – a fully-functional slot machine built from cardboard, popsicle sticks, and hot glue. We love the detail he included on the reels to make it look like the real deal. Stick around for a few other fun DIY builds in this compilation video.
As far as we know, the longest home run hit ever was 582 feet by Joey Meyer – and that was with the help of Denver’s thin air. But pesky human ball players are no match for Smarter Every Day and Jeremy Fielding’s terrifying motorized batter built to hit a ball at speeds up to twice as fast as an pro player – if it doesn’t self destruct first.
We’ve seen machines that can sort LEGO bricks before, but they’re generally limited to just a few specific shapes or colors. Daniel West’s machine is much smarter, using AI algorithms to identify and sort nearly 3,000 different LEGO shapes and colors. We think it’ll need more than 18 sorting bins to be really useful though.
These days, using machines to carve and sculpt is commonplace, but back in 1957 it was anything but. Back then, an ingenious inventor named George MacDonald Reid came up with a process that would snap 300 pictures of a subject’s head, then traced those images to carve it into a block of plaster, one section at a time.
This impressive piece of computer-controlled machinery from Germany’s J. Neu can take straight pieces of metal tubing, and bend them to its whim. We’re not getting the accompaniment of The Godfather music, but maybe it’s a threat that the machine will bend you like a pretzel if you go against it.
