This two-decade old blinkenlights project (YouTube link, and also below the break) would look at home among current $1 soldering kits except for a few key differences. Firstly, it has the teardown artist’s name on the back and comes from an era when DIY circuit boards really meant doing things yourself including the artwork, etching, […]
Lamps are quite often simple things, designed to light an area and perhaps add a touch of style to a room. Of course, it’s 2019 now, and we don’t need to settle for just that. We can have wildly colored animated lamps if we want to! (French Youtube link, embedded below.) The lamp in question […]
Newton’s Cradle was once upon a time, a popular desk toy in offices around the world. For [TecnoProfesor], however, it wasn’t quite flashy enough. Instead, they built a simulated version with flashing LEDs. As you do. Rather than relying on the basic principles of the cradle to make it work, this relies on two servo […]
We live in an era in which all manner of displays are cheap and readily available. A few dollars spent online can net you a two-line alphanumeric LCD, a graphical OLED screen, or all manner of other options. Years ago however, people made do with little monolithic LED devices. [sjm4306] wanted to recreate something similar, […]
If you’ve ever attended a hacker camp, you’ll know the problem of a field of tents lit only by the glow of laser illumination through the haze and set to the distant thump of electronic dance music. You need to complete that project, but the sun’s gone down and you didn’t have space in your […]
Wireless LEDs. That’s what [Scotty Allen] found in Japan, and if you find something you just have to replicate it. [Scotty] found these wireless LEDs in a display stand for model makers and gunpla. Because you don’t want to run wires, drill holes, and deal with fiber optics when illuminating plastic models, model companies have […]
In the practical world we live in, PCBs are often rectangles (or rectangles with rectangles, it’s just rectangles all the way down). When a designer goes to schematic capture things are put down on nice neat grid intersections; and if there isn’t a particular demand during layout the components probably go on a grid too. […]
Constrained builds are often the most fun. Throw an artificial limit into the mix, like time limiting your effort or restricting yourself to what’s on hand, and there’s no telling what will happen. [bitluni] actually chose both of those constraints for this ping pong ball LED video display, and the results are pretty cool, even […]
It’s now possible to source chip-on-board LED modules that have huge light output in a simple, easy to use package. However they can have major power requirements, and cheaper modules are also susceptible to dead spots.  [Heliox] put together a great LED lamp design the old-school way, showing there’s more than one way to get […]
Wearable electronics can be both fun and fashionable. However, there are certain challenges involved in neatly integrating electronic components in a way that is both functional and comfortable for the wearer. In this vein, [Jiri Praus] has managed to create some glowing earrings that are remarkably simple to boot. The body of the earring also […]
