The Physical

This project is to design a table that would have a moderately sized matrix of individual cells on the top that would act as pixels. Each so called cell would consist of an RGB Led to produce any given color value which would likely be achieved through pulse width modification. Each cell would also have a LED driver that would act as a slave to a main microprocessor on another main board. Including functionality like Timekeeping, various idling modes,and playing games such as “Snake”.

A quick overview of the base design materials is; made out of 7/32 3-layer birch plywood, laser cut, and diffuser on-top. The main design process followed (find a real-life reference) -> (find an accept- able way to integrate the LED’s into the design) -> (revise/repeat), the end result after multiple iterations is shown in the gallery. This design was done using Sketchup, and the overall design was driven by the concept of integrating the LED dividers into the table itself, thus resulting in this design. After the model was completed, it was further split up into separate "jobs" and thus was all laser cut with some additional pieces added in as a buffer for future accidents.

the table uses WS2812 based LEDs for both cost, and ease of implementation. The final design uses 16 strips of 32 LEDs each with power lines for every 64 LEDs and one continuous data line. The LEDs were attached to a backboard that was inserted into the table.
