#Build led light table serial#In that configuration, the Arduino Nano is used as a converter from the Pi's serial signal to the WS2812 protocol. However, the main drawback is that it's not open source. #Build led light table software#It is written in Java, which is a surprising decision for a software where performance is important, but it runs relatively well on the Raspberry Pi. #Build led light table plus#On the plus side, it's a really neat piece of software which allows highly customised animations and supports many matrix types and configurations, and it's free. Without any doubt, the king of diy led matrix animation software is Glediator. The animation above is simply the output of the XYMatrix example which is part of the FastLed library - highly recommended ! Raspberry Piįor more complex animations, and to handle the interactive part, small microcontrollers would probably be very limiting, so I switched to a Raspberry Pi as the main controller. The result with the acrylic plate (protection sheet not fully removed yet) is quite satisfactory : Software Arduino Nano #Build led light table series#I then pasted 14-led segments of the the self-adhesive strips to the bottom of the table, and connected the signal in series from line to line (in a zig-zag fashion), while the power for each segment is distributed from a central point to avoid the voltage drop across the 7-meter strip. I should have taken more care though, because the veneer wood layer of the LACK table is so thin that my masking tape pulled it out at places. That way, inner reflections will increase brightness and level out the intensity of each cell. Note that I first painted the cardboard, as well as the inside of the table and 4 small pieces of wood for the 4 inner sides in white. To create cell separations, I used thin corrugated cardboard but quickly found that cutting rectangular noches with regular spacing and depth was a very tedious task, so I piled up all the cardboard strips, stuck them between two old wooden planks and let my circular saw do the job. Less than 70 EUR qualifies for "cheap", and if you can find or recycle a power supply or an acrylic plate, you qualify for "dirt cheap". The rest (remains of white paint, cardboard, wires, etc.) I had laying around. I ended up buying it locally but I it's available online for 26.5 EUR, including s/h
