A TREE OF LEDS THAT BLOWS OUT LIKE A CANDLE

The beautiful workmanship in [Andrew]’s LED tree is gorgeous all on its own, but of course there’s more going on than meets the eye. This  LED tree can be blown out like a candle and it even playfully challenges a user to blow out all the lights at once in a single breath. Some of you may remember the fascinating example of an LED you can blow out like a candle which had the trick of using the LED ...

ICOSAHEDRON GLOWS WITH THE BEST OF THEM

Glowables come in all shapes and sizes, and we’re always keen to see the multitude of different ways hackers find to put great masses of LEDs to good use. [cabrera.101] wanted to get in on the action, and whipped up a rather flashy icosahedron. The build uses high-density 144-LED-per-meter strips for the edges, with 60-LED-per-meter strips used for the tubes that connect to the stainless steel ball in ...

BIG AND GLOWY TETRIS VIA ARDUINO

Tetris was a breakout hit when it was released for the Nintendo Game Boy in 1989, in much the same way that Breakout was a breakout hit in arcades in 1976. Despite this, gamers of today expect a little more than a tiny monochrome LCD with severe motion blur problems. Enter the LED Tetris build from [Electronoobs]. The build relies on a hacker favourite, the WS2812B LED string. The LEDs a ...

PERSISTANCE OF VISION ON AN OLD FAN

Persistance of vision is a fun feature of the human visual system, which allows us to blink a bunch of spinning LEDs at the right time to spell out messages that appear to hang in the air. [TN_Inventor] took a stab at his own POV build, using an old desk fan as a base. The initial build relied on a rotor made of MDF and some very old-school LEDs. The rotor was heavy and unbalanced, causing issues for the mo ...

MEASURE YOUR YOUTUBE IMPORTANCE

How do you hack your motivation? Do you put red marker Xs on a paper calendar every day you exercise? Do you use an egg timer to sprint through dozens of emails? Do you lock all the doors and shut off your data to write some bulletproof code? If you are [Hulk], you build a YouTube Desktop Notifier showing his YouTube subscribers and views. This is his ticket to getting off the couch to make a video about ju ...

A LASER CUT GINGERBREAD CATHEDRAL

One of the more disappointing news stories of 2019 was the fire at the Notre Dame cathedral. Widely considered a building of great historical importance and architectural merit, it was heavily damaged and will take significant time and resources to repair. Fundamentally though, if you’re reading this, that’s probably someone else’s job. Instead, why not just build your own Notre Dame out of gingerbread at h ...

The New Light-responsive Nano LEDs

A team of researchers from the US and South Korea reported a unique type of NanoLEDs with unprecedented brightness levels, that excess 80,000 cd/m2, and also can operate both as light emitters and light detectors. These new LEDs are about 50nm long and 6nm in diameter. As described in the paper, they included quantum dots of two different types, one of which can enhance radiative re-combinations (useful for ...
