Project 21: Empty RGB XMAS Tree

 

Project 21: Empty RGB XMAS Tree by  designer2k2

 

The holidays are a time for Doing-It-Yourself and making Small Things beautiful!

 

The LED rings are held by the copper wires that connect them, it is empty on the inside! The WS2812 RGB LED allows almost infinite colors and patterns to be created The code and a little guide can be found on Github

Project 22: LED fade in/out effect

 

Project 22: LED fade in/out effect by kk99

 

The holidays are a time when simple also means special!

 

The basic idea was to create a simple LED fade in/out effect circuit. kk99 used a single dual op-amp NJM4556 which first stage is configured in comparator mode and the second stage is configured as integrator. Triangular wave from integrator output is used to drive four LEDs. NJM4556 op-amp is able to deliver around 70 mA. It is enough to drive four LEDs with current 10 mA for each. Frequency of circuit is set to around 0.5 Hz. In his post you can find a schematic and details on the circuit, as well as, amplitude and frequency calculations.

"This was a nice simple circuit but which gave a really useful output. Could be used for system testing or in this case just flickering an LED nicely. Simple but effective and not a TTL gate in sight." - Community Member Judge

Project 23: Christmas tree made from WS2812 leds

Project 23: Christmas tree made from WS2812 leds by kk99:

 

The holidays are a time for Christmas trees and LEDs or just an LED Christmas tree!

 

A small Christmas tree made from 15 WS2812B LEDs connected to attiny13 MCU. Tree is made from 5 stripes with 5, 4, 3, 2 and 1 LEDs. LEDs are driven from single pinout PB4 of Attiny13 MCU.  MCU was put in cartridge from 35mm tape. As power supply I have used 5V from USB. Code is written in C.  There are five different effects for which you can modify brightness and delay.

Project 24: Jackbox

 

Project 24: JackBox by dubbie:

 

The holidays are a time for merry boxes & LEDs!

 

dubbie  has been looking forward to Christmas for some time and to making something electronicy with LEDs and Arduino. He loves a few LEDs and bits of tinsel. So he decided to have a go at the Merry Boxes and LEDS project. He started a while ago collecting bits to use anticipating a quick start, but Christmas preparations have intervened and he has only just been able to find some spare time. He's collected a few bits and a small wooden box and his intention is to make something relatively small that resides inside the box and then 'pops up'!  Having completed adding the sound he decided to improve the LED part a little bit. He took three of the LEDs white wooden snowflakes shapes and fixed them to the front and sides of the box. Rather than just these three LEDS on and off he decided to fade them on and off. To do this he just connected the three LEDs in parallel and then the positive (the anode) to the +5V from the Nano and the negative (the cathode) to the D5 output of the Nano. The LEDs will all come on when D5 is driven low. To create the fade on and off effect he used pulse width modulation implemented as next for loops, as illustrated in the code fragment below. He used a function just to make it tidier. The value input into the function controls the maximum brightness achieved by the LED, which also controls the frequency of the LED slowly pulsing.

Project 25: Mini Singing Holiday Tree

 

Project 25: Mini Singing Holiday Tree by carmelito :

 

The holidays are a time for music, merriment, and of course Mini Singing Holiday Trees! 

 

This is a great weekend project to undertake, to get you in the holiday spirit ! In all, it should be a few hours of 3D printing, and then an hour or so in soldering the circuit together, and uploading the python code to the Pi. As part of the build he is using a Raspberry Pi Zero W as the heart of the project, and a RGB led strip (APA102) to diffuse the LEDs through the 3D printed tree . In addition he is also using an I2S class D mono Amp breakout board by Adafruit based on MAX98357 chip and a small 8 ohms speaker, to play some Holiday songs.

Project 26: Santa Incoming Chimney! [SIC]

 

Project 26: Santa Incoming Chimney! [SIC] by robertwerner:

 

The holidays are a time for watching for Santa and not letting sleep get in the way!

 

ESP-Now device for warning of the approach of Santa!  This device has a Master which detects with PIR or a wire break to set a pin low--it is monitored when a TPL 5111 wakes the unit up.  The solar charger keeps the device charged with a battery mounted on the roof.  The receiver device (Slave) constantly monitors for the ESP-Now communication from the master and announces the arrival of St. Nick with a bright cascade of Led's.

Project 27: ESP8266 Magic Star Mirror with Alexa

 

Project 27: ESP8266 Magic Star Mirror with Alexa by jquest :

 

The holidays are a time to share wonder and delight with family!

 

This jquest ’s eldest daughter loves all things space and is constantly looking skyward at night wondering what planet she can see.  One night he taught her about constellations and she became obsessed with Scorpio so he made a small little display stand for her using some scrap outdoor solar LEDs. This quickly escalated to whether he could build something that had all 12 zodiac signs...and Orion...and the Little Dipper...and Alexa...and EVERYTHING!

 

Thus, the Magic Star Mirror was born.

Project 28: The Christmas Joy Spreading Machine

 

Project 28: The Christmas Joy Spreading Machine by balearicdynamics:

 

The holidays are a time for spreading joy to all around you!

 

This machine represents balearicdynamics ’s virtual Best Wishes for the holidays to all the community members.  The design idea was to make a complete scenario representing - inside a box  - a metaphor of the most popular Christmas symbols. Maybe it is a bit dystopian but it moves, lights and reacts to music. The other not easy aspect of the building was just to use the cardboard as the primary material. The central moving parts have been inspired by the incredible quantity of DIY Marble Machines you can find on YouTube (just put the two terms for searching videos and you remain speechless).

"As always, the quality of Enrico’s work is superb. This cleverly build machine truly brings fun and joy to the spectators, and also shows that any build material is good when used with ingenuity." - Community Member Judge

 

 

"Beautiful project, it left me almost speechless! I can't imagine a more fun project to make and also watch in action, at Christmas time." - Community Member Judge

 

Project 29: Flashy LED Picture Frame

 

Project 29: Flashy LED Picture Frame by tonydbeck:

 

Holidays are a time to be fascinated by LED displays and the effects that they produce!

 

tonydbeck has always been fascinated by LED displays and the effects that can be produced.  Over the last few years multi colour programmable LED's such as Neopixels, WS2812B LEDs etc seem to have become very popular and with the ever increasing amount of cheap development kits on the market it has become a lot more reachable for a hobbyist to create some pretty cool projects with LED's!  So tonydbeck  decided to build an LED matrix picture frame with an mbed LPC1768 board and 10m of WS2812B LED strip.  he programmed the LPC1768 board to use Art-Net so that he can send data to the matrix from my laptop using Madrix or Glediator software.  Although this is not the most creative LED project, I am still pretty pleased with it!

Project 30: Sparky the Power Chick Levitates - Happy New Year

 

Project 30: Sparky the Power Chick Levitates - Happy New Year by dougw

 

The holidays are a time for levity and remembering where you came from!

 

We first met Sparky the Power Chick during the first competition we launched Techno Toys.

 

Nothing like a cute new-born chick to welcome a new year...

 

Last year, Sparky the Power Chick returned to experiment with magnetic levitation!  Later the same year dougw was back with another project during the Electromagnetism competition.
