To prove just how versatile cardboard can be, Houston-based Victory Packaging turned up to a tradeshow with a 16-foot-tall gear-driven sculpture reminiscent of the space travel portals from Stargate. This isn’t the only time they built something awesome with cardboard.
Take a look at the video, and you’ll swear that these balls are spinning in a circular orbit. But look more closely, and you’ll see that each ball is moving along a perfectly straight path. The mechanical model is based on a design by 16th century Italian poymath Girolamo Cardano.
If you thought The Citadel was complex, check out builder Samuel Hunt’s insanely complex K’NEX ball machine. It’s made from over 50,000 pieces, has 6 networks, 33 paths, and 13 lifts. It took him nearly 2 years to construct and film all of its paths and mechanisms.
3DSage got their hands on this nifty mechanical device from Japan – it’s a hand-operated gadget which follows the outlines of a stack of disks to move its arm, which in turn draws a corresponding image. A web-based conversion tool is used to design disk templates.
Most digital displays are completely solid state, with no moving parts. But check out these nifty (and noisy) Alfa Zeta 7-segment displays from FlipDots, which look digital, but use magnetic fields to change states. Check out more cool FlipDot demonstrations here and here.
Design collective onformative shows off a nifty mechanical sculpture they created, which uses a series of spinning black metal tubes which allow light from an array of fluorescent bulbs to pass through. The result is a binary pixel display with an alluring soundtrack. More here.
Cube puzzle guru Tony Fisher decided to see how the insane 17x17x17 Yuxin Huang Long puzzle is put together, so he cracked it open to reveal the thousands of pieces which go into its assembly. Now it’s a whole new kind of puzzle to try and put it back together.
Up for a fun and challenging project with a satisfying result? Look no further than this wooden model of a London-style double decker bus. Once you assemble all 216 laser-cut parts, you’ll have a working vehicle that can actually move up to 12 feet on rubber band power.
Watchfinder & Co. provides an up close look at one of the cooler wristwatches out there, the A. Lange & Söhne Zeitwerk, which features a numeric display, but uses a mechanical movement to flip its digits. Also, we’ve been using the word “digital” wrong all this time.
We’ve seen metal miniature kits before, but never ones like these. Time 4 Machine’s big selling point is that their detailed models are mechanical. The wind-up cabrio and tank actually drive, the clock tells time (for an hour), and you can actually play the table hockey game.
This could be the most complicated clock ever built. We cannot imagine the engineering involved in getting all of its gears, pulleys, and pendulums to work together to tell time. Mark Frank and Buchanan’s masterpiece has been under construction for over a decade.
Beyond the Brick shows off Claus-Marc Hahn’s astounding model of the Red Keep from Game of Thrones. He used over 125,000 bricks, and a multiple EV3 servo motors to mechanize the build, so the whole thing turns, its towers move up and down, and their cupolas spin.
Fans of Super Mario Bros. will immediately recognize this obnoxious bit of vegetation as a Piranha Plant. Jason from JK Brickworks brought the creature to life in mechanized LEGO form, complete with a motor drive to pop the plant up and down from a pipe as it chomps its jaws.
Paul Myers designed this replacement interior door knob which can only be opened by dropping a marble into its top. It’s made from 3D printed PLA, Airsoft and skate bearings. You can pick one up in his Etsy shop, Beta Things. We dig his business card embosser too.
