Collaborate Disseminate
When [tnjyoung] was asked to build a huge lighted clock for a high school theater’s production of Cinderella with only two weeks before opening night, he probably wished for a fairy godmother of his own to show up and do it for him. But he and his team pulled it …read more
When we last saw [isaac879]’s levitating RGB time fountain, it was made of wood which meant that it would absorb water and didn’t really show off the effect very well. His new version solves this problem with an acrylic case, new PCB and an updated circuit.
Like the original, this …read more

Have you ever wrapped up a nice blinky project only to be disappointed by the predictability of the light or the color patterns? When it came to lighting this LED candle, so was [fungus amungus]. But there’s a better way, and it involves noise.
Perlin noise was created in the …read more
About a year ago, [Jonathan Bumstead] built a giant, touch-sensitive, interactive RGB LED geodesic dome that somehow escaped our attention entirely. For this year’s Hackaday Prize, he’s designed a smaller version that’s just as awesome, but a lot faster and easier to build.
The Bucky Glow is great way for hackers of all ages to expand their coding and problem solving skills. This interactive dodecahedron consists of 11 RGB LEDs and a Nano inside 12-sided laser-cut MDF sculpture. The breakout header means you’re free to add interactive bits like a DIY capacitive touch keyboard, IR sensor/emitter pairs, motors, or whatever …read more

For [LumoW], what started as a school project turned into a passion project. He and his team made a hardware implementation of an arcade game called Stacker. Never heard of it? It’s pretty fun, kind of like an inverse Tetris. You can play the flash version here and see their mini arcade version after the break.
The game is based around the Mojo FPGA which the class required, and it’s programmed entirely in bitwise operators. It uses WS2812 RGB LEDs to represent the individual tower building blocks, and these are mounted on plywood in a matrix and separated into cells …read more
Sometimes it’s not so much what you put together, it’s how you use it. The folks at Adafruit have put up a project on how to dress up your drone with ‘UFO lights’ just in time for Halloween. The project is a ring of RGB LEDs and a small microcontroller to give any quadcopter a spinning ‘tractor beam light’ effect. A 3D printed fixture handles attachment. If you’re using a DJI Phantom 4 like they are, you can power everything directly from the drone using a short USB cable, which means hardly any wiring work at all, and no permanent …read more

[Luc] wanted to make a clock like no other. He knows that the territory is well-trod, especially in the area of minimalist design. Undeterred, [Luc] came up with a fresh design that uses the resistor color code to display the time. He’s calling it the Nerd’s Ultimate Watch.
It doesn’t get much more minimalist than four RGB LEDs. Each one illuminates in the color that represents the digit in the current time. For instance, I’m typing this sentence at 1:37PM. The clock uses 24-hour time, so let’s call it 13:37. Using resistor color code time, that’s 1, 3, 3, 7, or brown, orange, …read more
