An animated Arduino LED matrix table is perfect for a maker’s wedding #ArduinoD14
Phil Tucker made this festive animated Arduino LED matrix lounge table for his wedding reception. It’s definitely the perfect touch to any social gathering!
Finally got around to making an LED table top, as it turns out — for my wedding reception. We decided to have a lounge area and an LED coffee table seemed like the perfect centerpiece for it. I decided instead of making a full table that I would make a table top that fit onto an existing ottoman. I affixed the LED strips to a plywood board which had a 2″ raised frame with aluminium duct tape, to help with brightness.
Arranging the LED’s in a proper matrix turned out to be quite a job as the strips I used came pre-wired and there isn’t all that much length between LED’s on the strip. I ended up having to cut and re-splice the connection leads for each row of the 7 x 7 matrix, after that the construction went quickly. You could get around this by using a more modular LED strip solution, I initially had ShiftBrites slated for this project, but I made something else with them and when I got around to this table top there were much less expensive options available.
12mm Diffused Flat Digital RGB LED Pixels (Strand of 25) – WS2801; RGB Pixels are digitally-controllable lights you can set to any color, or animate. Each RGB LED and controller chip is molded into a ‘dot’ of silicone. The dots are weatherproof and rugged. There are four flanges molded in so that you can ‘push’ them into a 12mm drill hole in any material up to 1.5mm/0.06″ thick. They’re typically used to make outdoor signs. These pixels have a flat square back, we also have pixels that are long and thin, both are the same electronics, just different shapes! (read more)
