Like the original, [noniq]’s version is laser cut and engraved, and uses some 3D printed parts. But it does away with the fasteners (that’s 60 pairs of nuts and bolts), and instead uses neodymium magnets to make all the triangle pieces snap together to form the icosahedron globe. The hinges are simply some pieces of gaffer-tape.
This design improvement creates a cleaner globe and also addresses some of the concerns posted in the comments of the earlier build. The design files are available for download on [noniq]’s blog — you need to 3D print some magnet holders and stopper plates, and laser cut the 20 triangle tiles. The stopper plates help ensure that the angle between tiles when it is put together is limited to 138 degrees, making it easier to assemble the globe.
Check out the video after the break to hear the satisfying “thunk” of neodymium magnets snapping together.
Everyone knows that globes are cool — what else would you use as the centerpiece of your library/study? But, sadly, making your own isn’t a simple process. Even if you had a large (preferably hollow) sphere to work with, you’d still have to devise a clever way of printing the map in sections that can be glued to the curved surface. Wouldn’t it be easier if you could just laser cut flat sections, and assemble them to form a faceted “globe?”
Well, it is, and you can! Because, [Gavin] over at tinkerings.org (a Hackaday favorite) has created the files to do just that! This map projection, originally designed by the very interesting Buckminster Fuller, is designed to be either laid flat or three-dimensionally on an icosahedron (a 20-sided polyhedron). That makes it perfect for laser cutting, as each of the 20 faces can be cut from flat stock.
[Dr.Duino] recently completed the latest piece of what he calls “Interactive Furniture” – the GoonieBox. It took over 800 hours of design and assembly work and the result is fascinating. Part clock and part puzzle box, it’s loaded with symbols, moving parts, lights, riddles, sounds, switches, and locked compartments. It practically begs visitors to take a closer look.
The concept of Interactive Furniture led [Dr.Duino] to want to create a unique piece of decor that visitors could interact with. That alone wasn’t enough — he wanted something that wouldn’t require any explanation of how it worked; something that intrinsically invited attention, inspection, and exploration. This quest led to creating The GoonieBox, named for its twin inspirations of the 1985 film The Gooniesas well as puzzles from the game “The Room“.
Embedded below are two short videos: the first demonstrates the functions of the box, and the second covers the build process. There’s laser-cut wood, plenty of 3D printed parts, and a whole lot of careful planning and testing.
Fearless makers are conquering ever more fields of engineering and science, finding out that curiosity and common sense is all it takes to tackle any DIY project. Great things can be accomplished, and nothing is rocket science. Except for rocket science of course, and we’re not afraid of that either. Soldering, welding, 3D printing, and the fine art of laminating composites are skills that cannot be unlearned once mastered. Unfortunately, neither can the long-term damage caused by fumes, toxic gasses and heavy metals. Take a moment, read the material safety datasheets, and incorporate the following, simple practices and gears into your projects.
Check out the great workmanship that went into [TonyRobot]’s coffee vending version of ROBOT CAFE at Tokyo Maker Faire 2016. We’d really like to see this in action, so if anyone has more success than we did at tracking down more info (especially if it’s video) let us know in the comments below. We spot laser-cut wood making up the clever scoop design (and the numerous gears within it) but simply must know more.
Technically this is less “robot” and more “automata“. The cart charmingly fuses vending machine practicality with a visual display… and a great one at that. The aesthetic of the Robot Cafe leaps over the uncanny valley and fully embraces lovable robot faces.
Coffee is ground by a manual-style grinder into a scoop, which is then dumped into a pour-over filter. The hot water is then raised from below to pour over the grounds. These characters can be reconfigured based on the needs of the venue. The creator page linked above has three pictures of the same cart and same robo-baristas, but they are fishing for sodas instead. The glass bottles are lifted through the hole you can see on the right of the cart’s counter, using a fishing line with a magnet to grip the metal bottle cap.
Part performance art and part social experiment, [mocymo]’s Smilemachine V6 helmet is as delightful as it is expressive. The helmet is made primarily from laser-cut MDF assembled around parts from a safety helmet. The display is an Android tablet with fine operation controlled by a Bluetooth mini keyboard, and the helmet cleverly makes use of the tablet’s ability to adjust the display to compensate for head tilt angle. It recently made an appearance at Maker Faire Tokyo, where the creator says the reception (especially by children) exceeded expectations.
There are several interesting things done with this device. One is the handheld controller, which is essentially a mini Bluetooth keyboard. To help allow fine control without needing to look down at the controller, the keyboard sits in a frame with some nuts and bolts used as highly tactile button extensions. By allowing the user to change the physical button layout (and setting up keyboard shortcuts on the device to match) the arrangement can be made more intuitive for the user. Some photos of this assembly are in the gallery after the break.
Another interesting bit is that despite a tablet being right in front of your eyes, it is possible to see out the front of the helmet while wearing it. The solution is completely low-tech: two mirrors form a periscope whose angle can be adjusted by turning a knob on the side of the helmet.
Version 1 of the helmet was started back in 2012; this is version 6 and [mocymo] is already filling out a to-do list for refinements. The nose area is uncomfortable, the angle of periscope is slightly off and the gearing needs to be reworked, among other things. We can’t wait to see Version 7. Video and gallery are embedded below.
[Dave Hrynkiw] wrote up some practical and useful detail around embedding electronics into clothing. It centers around his daughter’s “Starry Night” high school graduation dress, which is the culmination of a lot of experimentation in finding the best way to do things. His daughter accented the dress with LEDs to produce a twinkling starfield effect, and a laser-cut RGB pendant to match.
While [Dave] is the president of Solarbotics and pitches some products in the process of writing it all up, the post is full of genuinely useful tips that were all learned though practical use and experimentation. Imagine how awesome it must be growing up a child of a “local technology-hacking company” founder — akin to growing up as Willy Wonka’s progeny.
What advice does [Dave] have for making electronics an awesome part of garments? For example, the fact that regular hookup wire isn’t very well suited to embedding into clothing due to the need for high flexibility. There is also the concept of sequestering electronics into a separate Technology Layer — a must for anything that will be used more than once. The idea is to “build your technology so it can be isolated from the fashion aspect as much as possible. It makes building and maintenance of both the fashion and technology aspects much simpler.”
Slapping some LEDs and a battery pack into clothing might do the trick if all you care about is some bling, but if you want something that actually highlights and complements clothing while also being able to stand up to repeated use, this is a great read. A simple lighting effect that complements a design isn’t difficult, and there’s no need to reinvent the wheel or make the same mistakes others have encountered. Video is embedded below.
