Open Source Projects

The PCB for the first batch open hardware projects shared here is fabricated with Elecrow free prototyping for Christmas Theme PCB design and the designer approved elecrow to share the original design with Elecrow Customer. This Free Christmas PCB fabrication is not available now and if you need PCB fabrication, you can go to the PCB service Page to order online. There are some other Christmas related projects shared at Elecrow Facebook group for you design refer. If you have other opensource projects to share or any problem, please feel free to contact us via email at David@elecrow.com There are some designers sell products at Elecrow online store. You can go to this cooperator designers' products page to support the them.

• Elecrow Christmas Tree by Gerrit Maus

  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.

  Click to download the Circuit Gerber File.

  Visit the designer's website for more details.

• Snowflake designed by Buleks

  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

  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.
