Led Table

This is an IKEA Lack table that we carved out and put in a 12x12 Led Matrix made from ws2811 strips controlled by a raspberry pi zero w running a local webserver you can connect to with your phone or computer in order to play games or show cool animations.

The table runs a webserver where up to 4 players can connect and control the table from there. There are a few animations implemented as well as a snake game that supports up to 4 players at once.

The leds are about 5m of addressable neopixel strips with 30 leds/m. It makes a big difference using a white background and white strips as well as painting the dividers white on the sides and black on top in order to increase brightness and get better diffusion. I also used the WS2811 variant because they are 12v and have no voltage drop with high brightness whites which can lead to color shifts and stuck pixels.

The dividers are lasercut out of 3mm mdf but can also be printed but with the current models you might need quite a big printbed and have to be carefull as to not have any light bleed between the pixels.

For the electronics all you need is a raspberry pi, best to use a zero w to save space but you could also cramp in a full size model and you also need a power supply to power the pi.
