Our Dual Axis Solar Tracker has been a popular project since we first posted it on instructables.com back in 2015. Since the start we made all the files and resources 100% Open Source. Our original contribution to this type of project were our original laser cut design files, with the basic mechanics and code coming from long standing existing project guides.
Since then we’ve developed a V2 of the Dual Axis Solar Tracker using a tweaked laser cut design and custom printed PCBs. This allows for a much easier build on the electronics side while keeping the overall design and function the same. Instead of using a couple of terminal blocks to connect four resistors and a handful of colored wires we’re using a custom Arduino shield that everything plugs into.
Both the original V1 and new V2 files can be found on our GitHub Repo. If you wish to build this project from scratch (and not buy it from us) you’ll need access to a laser cutter that can cut both 1/4th and 1/8th inch wood/ acrylic. You can buy the custom PCBs from our website or use the Gerber files to get your own made up. Services such as OSH Park work well for small batches of PCBs.
You’ll also find design files for our analogue Single Axis Dumb Tracker which uses a DC geared motor and two solar cells to track the sun. At some point we’re going to revamp this project and use our Crazy Circuits Robotics Board to drive a servo and use the Dual Axis Sensor Board for input.
