I have one of these kits for sale for $15. Pick up at VHS. Everything is included. PCB is nice n’ solid. Tree runs off USB. Has an on off switch. Just flick the switch to change the light pattern. There are at least 12 patterns included all controlled by an IC.

Everything is included including usb cable.
If you have soldered at least once before this is a great project!
