PCB Christmas Tree

thingiverse

This Christmas Tree uses a design created by J.Daniel Herrera. A new base has been 3D printed and a small PCB built to hold an ATTiny85 microcontroller that drives the tree. Jingle Bells ------------ https://youtu.be/glbZrCg2oF4 Snoopys Christmas ----------------- https://youtu.be/eZCdyNJIgME Christmas Tree PCB ------------------------ The board layout is included in PDF form. The layout was printed from the PDF onto glossy paper using a laser printer, and then the PCB was made using the Toner method. Base ------------------ The base can be 3D printed without supports. The PCB was made with the Toner method (Eagle files are included). A DC socket is held in place by super glue, and the PCB is secured with hot glue. Programming the ATTiny85 ----------------- This is the most challenging part of the project. First, you'll need to obtain a "SOIC8 SOP8 to DIP8 EZ Programmer Adapter Socket Module With Wide 208mil" - The wide 208mil feature is crucial. Next, you must burn the Digispark boot loader onto the chip. Once that's done, plug the SOP8 to DIP8 adapter into your homemade Digispark board and upload the sketch (also included). Test the tree to ensure it's working properly, then solder the ATTiny85 microcontroller onto the PCB.
