Infinity Cube Is Gorgeous Yet Simple

Posted on by

Typically when we hear the words “LED” and “Cube”, we think of small blinking devices on protoboard designed to flex one’s programming and soldering skills. However, while [Heliox]’s Cube Infini could be described as “a cube of LEDs”, it’s rather a different beast (video in French, subtitles available).

The cube starts with a 3D printed frame, designed in Fusion 360. The devil really is in the details — [Heliox] puts in nice touches, such as the artistic cube relief on the base, and the smart integrated cable management in the edges. The faces of the cube are plexiglass sheets, covered …read more

BlinkBox: Debugging Tool For Addressable LEDs

Posted on by

How often do you find yourself having to pause a project to make a test circuit or write some test code to find the source of a problem? Do enough variations of the same test and you’ll eventually make a dedicated test tool. That’s just what [Devon Bray] found himself doing.

[Devon] does a lot of work with addressable LEDs of different types and after much experience, created the BlinkBox, a dedicated test tool for addressable LEDs. It supports multiple LED chipsets, you can give it a count of the LEDs you want to light up, and you can choose …read more

Wireless Ring Light For SMD Microscope

Posted on by

When [Felix Rusu], maker of the popular Moteino boards which started life as wireless Arduino compatibles, says he’s made a wireless ring light for his SMD microscope, we redirect our keystrokes to have a look. Of course, it’s a bit of wordplay on his part. What he’s done is made a new ring light which uses a battery instead of having annoying wires go to a wall wart. That’s important for someone who spends so much time hunched over the microscope. Oh, and he’s built the ring light on a rather nice looking SMD board.

The board offers a few …read more

Illuminated Bread for a Cookie Cutter World

Posted on by

Just in case you thought your eyes were playing tricks on you, we’d like to confirm right from the start that what you are looking at is a loaf of bread with internal LED lighting. Why has this bread been internally lit? We can’t really say. But what we can do is pass on the fascinating process that took an unremarkable piece of stale bread and turned it into an exceptional piece of stale bread.

As demonstrated by [The Maker Monster], working with stale bread is basically like working with wood. Wood that you can dip in soup, granted, but …read more

Soda Can Lamp Pinpoints Your Interests

Posted on by

We’ve said it a million times before: 3D printing will expand your horizons. The more you print, the more you think about things you could print and new ways to use printing in the process of building projects. [AHNT] knows all about this phenomenon, because he thought of a way to use soda cans as canvases for customizable pixel art lamp shades.

[AHNT] designed a printable sleeve that fits perfectly over 250mL cans. It provides a sturdy grid for poking tiny holes with a medical needle, and can be reused indefinitely with any pattern imaginable. He created two different printable …read more

Workbench Light Arch on the Cheap

Posted on by

A light arch is exactly what it sounds like: an arch fitted with LED strips that can evenly illuminate the area below. They are becoming very popular in the miniature and model making communities as they put a lot of light where you need it without the shadows that you can get with purely overhead lighting. Those same characteristics make it excellent for electronics work as well, so while we haven’t seen many light arches come our way yet, we expect it won’t be long before they start tricking in.

[Spencer Owen] recently wrote in to tell us about his …read more

Rotating Lithophane Box Turns with Time

Posted on by

If you wanted to make a rotating display box, what would you use to make it spin? A servo? A stepper motor? [ChrisN219] didn’t need his to move quickly by any means, and this opened up his options to something we probably wouldn’t have thought to use: a clock movement. Specifically, the hour part of the shaft.

Rotating lithophanes of your loved ones makes for a pretty cool project, and there isn’t a whole lot to this build to make it difficult. Much of it is 3D printed, including the tube in the center that the LED strip is wrapped …read more

An LED Effect for Every Occasion

Posted on by

Quality software development examples can be hard to come by. Sure, it’s easy to pop over to Google and find a <code> block with all the right keywords, but having everything correctly explained can be hit or miss. And the more niche the subject, the thinner the forum posts get. Bucking the downward trend [HansLuijten] provides an astoundingly thorough set of LED strip patterns in his comprehensive post titled Arduino LED strip effects.

Don’t let the unassuming title lead you astray from the content, because what’s on offer goes beyond your average beginner tutorial on how to setup a strand …read more

Great Emergency Lights from Not-So-Great UPS

Posted on by

We know your shame. Like you, we wanted to save some scratch and bought the bottom-of-the-range UPS, only to discover that it is no use to man or beast as it lacks the power to perform any reasonable task. It’s now sitting in a corner, to gather dust as its batteries deteriorate.

Not so fast with the UPS abandonment! [rue_mohr] came up with a modification for a small APC UPS that turned it into something a little more useful. Removing the mains inverter from the picture with a few displaced wires and PCB mod, the UPS is now a 12V …read more

Stecchino Game is all about Balancing a Big Toothpick

Posted on by

Self-described “Inventor Dad” [pepelepoisson]’s project is called Stecchino (English translation link here) and it’s an Arduino-based physical balancing game that aims to be intuitive to use and play for all ages. Using the Stecchino (‘toothpick’ in Italian) consists of balancing the device on your hand and trying to keep it upright for as long as possible. The LED strip fills up as time passes, and it keeps records of high scores. It was specifically designed to be instantly understood and simple to use by people of all ages, and we think it has succeeded in this brilliantly.

To sense orientation …read more
