Xmas tree with sound-controlled LED animations

Sound controlled LED light show for your Xmas tree.  An STM32 microcontroller takes instructions from a PC via Bluetooth and animates the LEDs. This is my Christmas tree, it has over 400 lights (exactly 404) that are all individually controlled by an STM32 microcontroller. The computer plays the music and processes the sync track for […]

Christmas Tree O’Digital Logic

Chris from PyroElectro writes about his holiday project. “It’s an all-digital-hardware LED Christmas tree we’re calling the Christmas Tree O’Digital Logic. The tree itself is composed of 64 LEDs built into a spiral sitting on a piece of protoboard. Underneath, the controller uses shift registers and a 555 timer to create two modes of display: […]

Flickering pumpkin LED designed in KiCAD

Add some LED goodness to this year’s Halloween pumpkins. This flickering LED design on a pumpkin shaped PCB was drawn up in KiCAD. Grab the design files from the low voltage labs site. It’s a simple schematic with just a switch, resistor, battery holder and 10mm LED. But makes for a nice easy project to […]

Easy to build spirit detector

Halloween is just a few weeks away so why not be prepared with your own easy to build spirit detector! The simple circuit described in this post by fritsl from Let’s Make Robots uses only three BC517 transistors and three resistors connected to an LED, antenna and 6-volt power source to build a device capable […]

DIY Santa Claus Singer with Flyport

Stefano has completed work on a holiday project known as the DIY Santa Claus Singer with Flyport. It is built around an animated Santa Claus decoration with the control switch bypassed with an NPN transistor. The switch is controlled over the internet via the Arduino/ethernet shield combo which responds to Twitter messages. Part one of […]

Christmas Tree email alert

Matt Richardson from MAKE presents his take on the traditional CHristmas tree email notifier utilizing the Arduino and the Ethernet Shield. He says: “On a set interval, the Arduino will connect to a PHP-enabled web server which will, in turn, check for new email. The PHP web server will return the count of messages to […]

ATtiny13 controlled LED Christmas lights

A simple example of a Christmas light project using store bought LED lights and components you probably have lying around the shop. Mark VandeWettering found a set of battery powered LED Christmas lights and decided to combine this this an ATtiny13 to make an MCU controlled lighting display. He explains: I found a set of […]

How to make a CheerLights controller with Arduino and ioBridge

CheerLights is an ioBridge Labs project that allows people’s lights all across the world to synchronize, stay linked based on social networking trends. It’s a way to connect physical things with social networking experiences and spread cheer at the same time. We are all connected. The Arduino is used to generate the PWN signal to […]

Colornode holiday lighting microcontroller board

ColorNode is a wireless Arduino-compatible microcontroller board designed to replace the stock controller board on GE Color Effects light strings. It’s a project designed by digitalmisery and was inspired by deep darc’s Hacking Christmas Lights project last year. The schematic and photos are available, and they promise to post the code as soon as the […]
