Best Xmas PCB projects - Opensource and DIY Happiness

Merry Christmas!

Christmas is coming and it's time to be a maker to decorate ourselves. A lot of customers shared their DIY Xmas projects with us in Elecrow Facebook Group. The following projects are some great projects that I picked out. please feel free to share your projects and happiness with us. 

Stars PCB with WS2812B LEDs

This porject was shared in Elecrow facebook group by Tomek Dutka.  it's the most welcomed Xmas project.

Hi everyone, I present stars PCB with WS2812B leds. 
Stars can be controlled with arduino but because of too little free time I used a driver SP103E with radio remote control.

For each star you can be made any visual effect and on the each star the visual effect can be different at the same time. You're limited only by the imagination and programming skill.

Each star has 21 SMD LEDs. LEDs are soldered to the top side of the PCB while the remained components are soldered to the bottom layer of the PCB. In addition, on each circuit board includes elements such as: - 330R resistor, capacitor 10uF / 10V Schottky diode BAT54S, 100 nF capacitor for each led.

Below are some photos and video but in reality it looks much better. Sorry I do not have a good camera so the movie looks weak.

Thank you for PCBs ELecrow.
Merry Christmas.

Xmas PCB tree with ws2812 leds

Shared by Chantal Thivierge at Elecrow facebook group.

Our famlly project for this year contest. Daddy did the design, mommy did the SMD soldering, the kids did the TH soldering and final assembly. Each tree have 136 ws2812b powered using an esp8266. A rotary dip switch is used to select the animation and a potentimeter is used to dim the intensity of the leds. 4 of the trees were given to the kids teachers as a special Christmas gift.

Merry Christmas:)


Asembled PCB made christmas tree decoration

Shared by Alexandru Babaian at Elecrow Facebook group.
Hi everyone. 
I would like to present a Christmas tree decoration made out of PCB's.The boards haven't arrived yet, so I would like to present the design files first.
The boards have to be manually depanelized and soldered in a shape of a lantern. On the top square pcb a WS2812B LED has to be mounted in order to illuminate the interior of lantern. Due to the fact that 0.6mm pcb's are quite transparent, images printed on copper layers, solder mask and overlay layers will be clearly visible.
An array of such lanterns will be made.

Merry Christmas!
