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 […]
Here’s a fun project in the Christmas spirit. It’s a “Jingle bells” playing card, with the specific notes being signaled via LEDs as they are being played. We have 9 control lines for the LEDs and 1 line for the speaker signal. We want the device to start playing if a push button is pressed […]
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: […]

Happy Thanksgiving from Seeed Studio! Thanksgiving is just around the corner. We would LOVE to thank our families and friends for always standing by our sides. And we would LOVE to take this opportunity to give our special thanks to our dear customers, distributors, cooperated designers, to show our gratitude to the Open Hardware Community. […]
Happy Thanksgiving to all our USA friends from DangerousPrototypes!
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 […]
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 […]
It’s National Geek Day / Geek Pride Day! According to Wikipedia, “Geek Pride Day is an initiative to promote geek culture, celebrated on 25 May. The date was chosen as to commemorate the release of the first Star Wars film, A New Hope on 25 May 1977 (a/k/a Star Wars Day), but shares the same […]
Happy International Women’s Day. Our community can only benefit from diversity and the involvement of anyone who wears the label engineer, hacker, or maker. Ada Lovelace, Adafruit’s namesake, is considered to be the world’s first computer programmer.
“”He who receives an idea from me receives it without lessening me, as he who lights his candle at mine receives light without darkening me.”” – Thomas Jefferson Happy President’s Day!
Happy New Year! Thank you for reading the blog and being part of our community in 2011. We’re looking forward to more open hardware projects, more how-tos, more videos, more free PCBs, and more hacking in 2012.
What geek gifts did you get? We liked these gloves that work on capacitive touch screens like iPods, phones, etc. Silver threads in the fabric stimulate the screen. Now we don’t have to take off our gloves to reply in the forum.
Santa’s got some help delivering these toys! Merry Christmas to All! Remember, support is available on Christmas. Just give us a shout in the forum.
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 […]
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 […]
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 […]
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 […]
Happy Thanksgiving to all from DangerousPrototypes!
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 […]
