A simple, original and cheap Christmas tree made with LED-illuminated plastic straws that can be controlled over WiFi.
Things used in this project
This is an original, cheap and easy-to-do “Internet of Holiday Things” project. It consists of a small Christmas tree made with plastic straws with LEDs under them, so we can create beautiful light effects.
It can be mounted on the protoboard itself as I did, but it will look better if we solder the LEDs on a perfboard or make a simple PCB so that the tree shape is smoother (KiCad PCB files attached). If we mount the circuit on the protoboard, a custom alignment piece made with cardboard or rigid plastic is highly recommended (I made it with transparent plastic from a container cover), so that the LEDs and straws stays in place.
