PCB Tic-Tac-Toe & Light Sculptures

Tic-tac-toe game and light sculptures with single-PCB design.

This was designed to be an easy first project for people to learn to design PCBs in KiCAD. It only uses very standard parts, all in the KiCAD standard library; LEDs, resistors, and 2.54mm headers (all THT). The PCBs are assembled to be board tiles, X pieces, and O pieces. The pieces have LEDs and an X or O (sort of) pattern, which light up when plugged into a board tile.

After building the tic-tac-toe game, I realized I could make more arbitrary structures with the same PCB, by assembling it in different ways. I then made a slightly modified design to make it slightly more versatile for structures, and with the tic-tac-toe markings removed.

The PCB has a grid of 3x3 LEDs in the middle, a single resistor for the LEDs, 3-wide headers (GND-VCC-GND, symmetrical, so they can be plugged in either way) in the middle on each side for board tiles to connect, and a set of vertical headers in each corner to plug the piece tiles into.
