Colordance Circle

An art project that uses arrays of colored lights around a circle to create kaleidoscopic colored shadows.

"This is not an officially supported Google product"

Building

This project uses two build systems, PlatformIO and CMake. PIO is for code which runs on embedded devices - these run the actual hardware. CMake is for running tests on standard PCs.

To build with PlatformIO, run pio run -e <env>, where <env> is one defined in platformio.ini (e.g. teensy).

To run the tests:

text

mkdir -p build
cd build
cmake .. -DBUILD_SIMULATOR=false
make && ./generictest

Simulator

The simulator uses SDL2 to render the LEDs. To build it, first install the SDL2 development library

sudo apt install libsdl2-dev

then, from the build directory, configure CMake to build it with

cmake .. -DBUILD_SIMULATOR=true

then build and run it with

make && ./lib/simulator/Simulator

Processing

To run the simulator with the Processing controller, from the build directory run:

bash

${PROCESSING_HOME?}/processing-java --sketch=../controller/processing_controller --run | ./lib/simulator/Simulator

Questions

How big is the Pole node PCB?

It measures 93 × 27.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pole node use?

46 parts, built around the SP485ECN-L/TR, XL1509-5.0E1, 78208-103HLF and RMCF0603JG120R. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Pole node KiCad files?

From the ademuri/colordance-circle repository on GitHub, at the commit this page was made from: the board is hardware/pole-node/pole-node.kicad_pcb and its schematic hardware/buttons/button-holder/button-holder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pole node design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
