Retro Flip Clock Gets A Retrofit

Posted on by

Retro tech is almost always ripe for the hacking — be it nostalgia, an educational teardown, or acknowledging and preserving the shoulders upon which we stand. Coming across an old West-German built flip clock, YouTuber [Aaron Christophel] retrofitted the device while retaining its original mechanical components!

No modern electronics are complete without LEDs of some kind, so he has included a strip in the base of the clock face for visibility and cool factor. He doesn’t speak to the state of the clock beforehand, but he was able to keep the moving bits of the clock working for its second …read more

Warhammer 40K Model Rocket Launcher

Posted on by

[Daniel L]’s friend has a passion for Warhammer 40K. [Daniel] himself has a similar zeal for perfection in details. When he remembered a long-forgotten request to build a working rocket launcher for one of his friend’s Warhammer 40K models — well — the result was inevitably awesome.

The MicroMaxx motors — one of the smallest commercial rocket motors on the market — he had on hand seemed to fit the model of the Hyperios Whirlwind anti-air rocket tank. Modeling and 3D printing all the parts proved to be easier than assembling the incredibly detailed model — on top of sanding …read more

The Majesty of Saturn’s Rings Lighting Your Abode

Posted on by

[Modustrial Maker] is at it again with another seriously cool LED visualizer. This time around, he’s built pair of pendant lights inspired by the rings of Saturn.

The rings are made mostly of walnut plywood using a circle router jig to make the cut easier. If you are inspired to make these for yourself, [Modustrial Maker] is clear — the order in which you cut out the pieces of the rings is absolutely critical. The pieces are glued together — with any edges sanded smooth — and edgebanding applied using a hot air gun due to the curved surface before …read more

Bark Back IoT Pet Monitor

Posted on by

Does your pet get distressed when you’re not home? Or, perhaps their good behaviour slips when you’re not around and they cause a ruckus for the neighbours. Well, [jenfoxbot] has just such a dog, so she built a ‘bark back’ IoT pet monitor to keep an eye on him while she’s out.

The brains and backbone of the pet monitor is the ever-popular Raspberry Pi 3. A Sparkfun MEMS microphone breakout board listens for any unruly behaviour, with an MCP3002 analog to digital converter chip reading the mic input. Some trial-and-error coding allowed her to set a noise threshold that …read more

Flowing Light Art Inspired By Plankton

Posted on by

With today’s technology, art can be taken in directions that have never before been possible. Taking advantage of this, [teamlab] — an art collective from Japan — have unveiled an art installation that integrates the attendee into the spectacle. In the dark room of the piece ‘Moving Creates Vortices and Vortices Create Movement,‘ you are the brush that paints the flowing display.

Inspired by the movement of ocean plankton, this borrows your movement to create tapestries of light with mirrored walls to aggrandize the effect. As attendees walk about the room, their movements are tracked and translated into flowing patterns …read more

An IoT Christmas Tree For Your Hacker-Mas Celebrations

Posted on by

Smart Christmas trees may soon come to mean something more than a fashionably decorated tree. Forging ahead with this new definition, [Ayan Pahwa], with help from [Akshay Kumar], [Anshul Katta], and [Abhishek Maurya] turned their office’s Christmas Tree into an IoT device you can watch live!

As an IoT device, the tree relies on the ever-popular ESP8266 NodeMCU — activated and controlled by Alexa, as well as from a web page. The LEDs for the tree — and the offline-only tree-topper controlled by an Arduino Pro Mini — are the similarly popular Neopixels.

For those viewing online, a Raspberry Pi …read more

One String, One Print, One Harp

Posted on by

To exclude musical instruments in the overflowing library of possibility that 3D printing enables would be a disservice to makers and musicians everywhere. For the minds over at [Makefast Workshop], an experimental idea took shape: a single stringed harp.

The TuneFast Harp needed enough notes for a full octave, robust enough to handle the tension of the string, a single tuning mechanism and small enough to print. But how to produce multiple notes on a harp out of only one string? V-grooved bearings to the rescue! The string zig-zags around the bearings acting as endpoints that rotate as its tuned, …read more

Wireless Charger Truck Mod Keeps Juice Flowing On The Move

Posted on by

Wireless charging is great tech, but its relative novelty means it may not be everywhere you want it. When one of those places is your vehicle, well, you make like [Braxen McConnell] and crack it open to install a wireless charger!

After dismantling the centre console, [McConnell] had to make a few cuts behind the scenes to make room for the wireless charger — as well as cutting down the charger itself. He also took apart the charger and flipped the board and charging coil around inside its case; the reason for this is the closer the coil is to …read more

A Clear Christmas Tree Means More Lights!

Posted on by

For all the hustle and bustle of the holiday season, people still find ways to make time for their passions. In the lead up to Christmas, [Edwin Mol] and a few co-workers built themselves an LED Christmas tree that adds a maker’s touch to any festive decor.

Before going too far, they cut out a cardboard mock-up of the tree. This an easy step to skip, but it can save headaches later! Once happy with the prototype, they printed off the design stencils and cut the chunks of clear acrylic using power tools — you don’t need a laser cutter …read more

BeefBot: Your Robotic Grill Master

Posted on by

Have you ever been too busy to attend to the proper cooking of a steak? Well, lament no more, and warn your cardiologist. A trio of students from Cornell University have designed and built the steak-grilling BeefBot to make your delicious dinner dreams a reality.

[Jonah Mittler], [Kelsey Nedd], and [Martin Herrera] — electrical and computer engineering students — are the ones you should thank for this robot-chef. It works as follows: after skewering the steak onto the robot’s prongs, BeefBot lowers it onto the grill and monitors the internal temperature in a way that only the well-seasoned grillmaster can …read more
