“I made the tree a long time ago (i believe i was 12 or so), but several improvements have been made this year.
First i hollowed out the trunk (with careful drilling), and drilled small holes through to each branch level. I then fed magnet wire up through the trunk and out the holes, and soldered on the LEDs. The red LEGO brick in back houses the resistor and power switch; the base is some random PCB i scrounged.
This year i substituted a USB plug for the original wall-wart that powered it, and added the Festivus pole. The latter is removable for storage and is, of course, made from aluminum tubing (Very high strength-to-weight ratio).
Happy Holidays!” – Link.
