That doesn’t mean you can’t have a little fun with a desk toy inspired by the waves. Obviously, for the office-bound, surfing is simply out of the question during the working day. In 1994, Weezer famously said that “ you take your car to work, I’ll take my board”. Posted in Arduino Hacks Tagged apa102, arduino nano, desk toy, POV, standing wave We love all kinds of lamps around here, from the super-useful to the super-animated.

IT DESKTOP TOYS CODE
has an active Kickstarter campaign going for Pisces, and one of the rewards is the code and STL files. Everything is controlled with an Arduino Nano clone. Those old standby 2812s don’t have a high enough max refresh rate, so sprung for APA102Cs, aka DotStars. The stroboscopic effect hinges on the choice of LED. And of course, poking the string will cause interesting interruptions. A second pot sweeps through eleven preset patterns that vary the colors and visual effect. The strobing LEDs turn the string into an array of optical illusions depending on the strobing rate, which is controlled with a potentiometer. Here’s what is happening: two 5V DC motors, one running in reverse, are rotating a string at high speeds. This intriguing lamp is designed to illustrate Pisces, that mythological pair of fish bound by string that represent Aphrodite and her son Eros’ escape from the clutches of Typhon. And the best part? You can stick your finger in it. All at once, it demonstrates standing waves, persistence of vision, and the stroboscopic effect. It’s ’s latest installment in a line of mesmerizing, zodiac-themed art lamps that started with the water-dancing Aquarius. This thing right here might be the coolest desk toy since Newton’s Cradle. Video after the break.Ĭontinue reading “Building A Levitating Turbine Desk Toy” → Posted in Misc Hacks Tagged desk toy, Magnetic levitation It may be frivolous, but at the larger scale, magnetic levitation is put to more serious uses like high-speed transport. It makes for a captivating desk ornament, and one that can be tinkered with by changing the turbine blades for different performance. It’s possible that with very careful attention to detail in alignment, the pin could be eliminated, but it makes the system far more robust and reliable to have it there.įloating in the magnetic field, a simple puff of air is enough to set the turbine spinning for quite some time. This presses against one part of the frame in order to keep the turbine from being pushed out of the magnetic field entirely. One concession made to functionality is a sewing needle inserted into the turbine. When aligned properly, the turbine will hover over the frame and can spin freely with almost no friction. Two magnets are fitted to each frame piece, and one magnet is inserted into each end of the turbine. Rare earth magnets are then slotted into the parts in order to create the levitation effect. The turbine is also 3D printed, making it easy to create the complex geometry for the curved fins. The build uses a combination of 3D printed parts and metal rods to form a basic frame. If you want something suitably distracting in this vein for your own desk, consider building this levitating turbine from . Seeing small objects wobble about while seemingly hovering in thin air never gets old. Magnetic levitation is a beautiful thing to watch. Hot squirted plastic not your thing? We’ve previously seen a wooden escalator designed to keep a Slinky in motion for as long as it takes for you to realize you could be using your skills for something more constructive.Ĭontinue reading “Up Your Desk Toy Game With This 3D Printed Escalator” → Posted in Toy Hacks Tagged 3D printed parts, desk toy, escalator, gear motor, motorized
IT DESKTOP TOYS MANUAL
hasn’t had a chance to document the build process for the motorized version of the escalator, but as most of the parts are compatible with the manual version, you should be able to figure it out by referencing the earlier assembly guide. When you’ve run the cell down, and you will, there’s an onboard TP4056 charging module to keep the good times rolling. There’s no fancy motor controller here - just flip the switch and you’ve got 30 RPMs worth of stair-steppin’ action. While the core mechanism is largely the same, the powered unit uses a N20 geared motor and an 18650 cell. But for our money (and 3D printing time), we’d definitely go with this new motorized variant. But now that you’ve seen it, can you really say you don’t want one of your own? The design comes our way from, and is actually the logical evolution of a manually-operated version released previously. Let’s be real, nobody needs a tiny motorized escalator for their desk.
