Keith of “Keith’s Test Garage” wanted an LED candle. While somewhat realistic flicking units are easy to find, he was in search of something much more like the actual thing, and after several years of work has come up with a rather amazing replica. The device’s wax-embedded glass enclosure houses an Arduino, along with a […]
Maker Jeremy S. Cook has experimented with both CNC machinery and light painting in the past, and decided to combine these two skills into a new artistic device. His setup uses a web app found here to program a CNC router as a sort of dot matrix printer. But instead of a pen, pencil, brush […]
As seen here, Juan had some problems with his power supply, and while he wanted to “simply” build another one, he didn’t let the power supply go to waste. Instead he converted it into an adjustable dummy load based on the design by Dave Jones’ shown below. This device, however, is no mere duplication of […]
If you’ve ever considered building your own RC hovercraft, be sure to check out the latest project from “How To Mechatronics.” The build shows how to assemble one using a variety of 3D-printed parts, a pair of brushless DC motors for hover airflow and forward motion, and a servo for steering. An Arduino Uno along […]
Ultrasonic sensors, which emit a high frequency sound wave then listen for its return to determine an object’s distance, are useful in a wide variety of robotics projects. If you’d like a visualization of how the sensor views an area, this “radar” from Mr Innovative presents a fun option. The 3D-printed console features a small […]
While channel surfing might increasingly seem to be a thing of the past, Kevin Darrah demonstrates that it’s possible to control your streaming computer with a traditional TV remote. His simple solution reads IR signals with an IR detector module, which can then be passed along and translated into USB keypresses for computer control. You […]
Regular icosahedrons are 20-sided polyhedrons formed out of equilateral triangles. As such, the geometry behind making one is slightly complicated, but the results in the case of this light-up device appear to have been well worth it. The project’s write-up does go over how to actually model these faces in CAD but also provides the […]
Depending on your personality, you may tend to dominate a discussion, or metaphorically slink back into the corner, waiting for a turn to speak that never comes. MIT Tangible Media Group’s SociaBowl, however, aims to change this as “a dynamic table centerpiece to mediate group conversations.” SociaBowl takes the form of a circular standing table, […]
Interactive video games take many forms, but for the most part, each player has a separate controller that manipulates an onscreen character, vehicle, or other singular element. What if, as in real life, multiple players have to work together with physical objects to control a sailing ship? That’s the idea behind HOT SWAP: All Hands […]
If you want a DC power supply that works well, there are a number of places to buy such a device. If, however, you want to learn how one operates, and perhaps build your own, the video below by YouTuber Electronoobs will show you how to accomplish this feat. His project uses a transformer to […]
