Bringing A Child’s Play Kitchen To Life

Given how many adults will go out of their way to avoid spending any extended amount of time in the kitchen, it’s pretty amazing how much children love playing in their miniature versions. Especially since they tend to be pretty simple: usually they’re little more than different sized boxes made …read more

Can You Live Without the WS2812?

As near as we can tell, the popular WS2812 individually addressable RGB LED was released to the world sometime around the last half of 2013. This wasn’t long ago, or maybe it was an eternity; the ESP8266, the WiFi microcontroller we all know and love was only released a year …read more

An ESP8266 Sundial For Your Wall

Hackers absolutely love building clocks. Seriously, there are few other devices for which we’ve seen such an incredible number of variations. But while the clocks that hackers build might blink out the time in binary, or write it out in words, they generally don’t feature hands. Apparently in 2019 it’s …read more

Fueled By Jealousy, This Smart Lamp Really Shines

As a lover of lava lamps, [Julian Butler] knew when he saw a coworker’s modern LED incarnation of the classic piece of illuminated decor that he had to have one for himself. The only problem was that the Kickstarter for it had long since ended, and they were no longer …read more

Cylindrical LED Display Comes Full Circle

According to [makeTVee], his latest project started out as an experiment to see how well the LED matrix techniques he’s worked with in the past would translate to a cylindrical form factor. We’re going to go ahead and say that not only was the test a success, but that the …read more

Ask Hackaday: Can We Get Someone To Buy And Destroy RAM?

We like blinky things. We’re moths drawn to the flame of serially-addressable RGB LEDs. If the LEDs are smaller, we want to know. If you can drive more of them, we want to know. That said, the most interesting news out of CES last January was both right up our …read more

Pringles Can Turned Vaporwave Lamp

We play host to a lot of incredibly complex projects here at Hackaday; take a look at some of the entries in the Hackaday Prize for some real world-class engineering. But the hacks you can knock out in an afternoon are often just as compelling as the flagship projects. After all, not everyone is looking to devote years of their lives into building some complex machine.

Case in point, this very slick lamp built by [mytzusky]. Made of nothing more exotic than an old Pringles can and an RGB LED strip, this is something that can potentially be built with …read more

Trashed TV Gets RGB LED Backlight

It might not be obvious unless you’ve taken one apart, but most of the TVs and monitors listed as “LED” are simply LCD panels that use a bank of LEDs to illuminate them from behind. Similarly, what are generally referred to as “LCDs” are LCD panels that use fluorescent tubes for illumination. To get a true LED display with no separate backlight, you need OLED. Confused? Welcome to the world of consumer technology.

With those distinctions in mind, the hack that [Zenodilodon] recently performed on a broken “LED TV” is really rather brilliant. By removing the dead white LED backlights …read more

Gaze Upon This Daft Punk Helmet’s Rows of Utterly Perfect Hand-Soldered LEDs

The iconic robot helmets of Daft Punk feature prominently as challenging DIY hardware projects in their own right, and the results never disappoint. But [Nathaniel Stepp]’s photo gallery of his own version really sets the bar in both quality and attention to detail. The helmet uses a Teensy 3.2 as the main processor, and the visor consists of 328 hand soldered through-hole APA106 addressable RGB LEDs. A laser cut panel serves as the frame for the LEDs, and it was heat-formed to curve around the helmet and mate into the surrounding frame. Each LED is meticulously hand-soldered, complete with its …read more

Buttery Smooth Fades with the Power of HSV

In firmware-land we usually refer to colors using RGB. This is intuitively pleasing with a little background on color theory and an understanding of how multicolor LEDs work. Most of the colorful LEDs we are use not actually a single diode. They are red, green, and blue diodes shoved together in tight quarters. (Though interestingly very high end LEDs use even more colors than that, but that’s a topic for another article.) When all three light up at once the emitted light munges together into a single color which your brain perceives. Appropriately the schematic symbol for an RGB LED …read more
