Elecrow Christmas Tree by Gerrit Maus
Designed by Gerrit Maus; PCB manufactured by Elecrow.This Christmas tree is a simple circuit with some LEDs around an Atmel ATMEGA328P with the possibility to measure the battery voltage. All LED currents are planned to be very low so all LEDs will be driven by the microcontroller itself. In the download section you will find the schematic (pdf) and all Gerber files.

Snowflake designed by Buleks
Designed by Mateusz Zapart; PCB manufactured by Elecrow.Snowflake which can be mounted on Christmas tree. It contains six RGB LEDs which can light in different patterns.It is powered by li-po cell and can be charged by Micro USB connector. It contains Bluetooth low energy(nRF51) which can be used to check the battery state and modify lighting patterns. Hardware Design PCB was designed using Circuit Maker. The project can be seen here. The software will be made using the C++ Microhal library.

Christmas tree PCB decoration designed by Adrian Virna
Designed by Adrian Virna; PCB manufactured by Elecrow.This Christmas tree PCB decoration shared at Elecrow Facebook group too. If you want, we can make a user friendly panel (easily depanelizable) or a set of separate PCB's. You could sell it as a DIY kit (maybe together with ws2812 led/Arduino). The customer will have to solder the boards together.
