The NeoPixel LED tree is beautifully made from laser cut 3 mm Baltic birch plywood and is powered by a NodeMCU Amica ESP8266 32-bit Wi-Fi enabled processor. With 93 individually addressable NeoPixel LEDs, and remote controllable from any browser on your Wi-Fi network, this tree can’t be topped!
This six-digit, beautifully designed timepiece showcases cold war era components — Numitrons instead of Nixie tubes — along with modern LEDs and a Microchip PIC to create not only a useful clock but a great conversation piece as well.
Just when you thought there were no more cool electronic clocks to build, this Arduino-controlled version showed up.
Want to be sure you’re playing musical chords correctly? This unit will tell you if you are and display a light show in the process. I stumbled upon this circuit while trying to design a custom frequency tuner for my guitar and is hands down the best sound to light device you could ever build.
Those 8 x 8 matrix displays are good for more than just making scrolling signs. With a little imagination and a whole lot of extra time on your hands, you can actually use them to create simple yet amazing little action games. If the game is interesting enough, at some point you stop noticing that it is taking place on a field of only 64 LEDS. The only thing that matters is victory.
This article shows you how to build a really cool 3D cube with a 4 x 4 x 4 monochromatic LED matrix which has a total of 64 LEDs.
