Christmas Tree PCB

'Tis the Season for Makers

For Christmas 2023, I designed and built these Christmas tree PCBs as gifts for my relatives. I also used this project as an opportunity to learn PCB Art, ATtiny microcontroller programming, and SMD component soldering. This project demonstrates how free and open-source software can be leveraged to realize hardware and software projects.

Instructions

To make your own Christmas tree PCB, a complete instruction guide is available in how-to.md.

Acknowledgments

Thanks to @nadarbreicq for helping me choose the right family of ATtiny for my project needs. Both Barbatronic and Heliox made good videos for anyone starting projects with ATtiny microcontrollers:

• @nadarbreicq - Create flexible circuits with a vinyl cutter to make robots!: https://youtu.be/GuyE88zjXyU
• @HelioxLab - Program microcontrollers for your circuit boards! (ATtiny): https://youtu.be/KPtmi16cyaA

This project has been realized with the following stack of Free Open-Source Software. Thanks to the maintainers and contributors of these software tools:

• FreeCAD for the outline
• Inkscape for the decoration and the art on the PCB
• KiCAD for the PCB design
• PlatformIO for programming
