Lil’Red – BMX Solar Tracker
Project: Dual-axis solar tracker made from a boy's BMX bike frame
Lil'Red can be used to boost PV output over 40%, or even as a heliostat. It uses two separate single axis tracking controllers that were designed to be as simple yet compact as possible. The "TinyTracker" controllers are an effect yet low-cost device based on the Atmel ATTiny85 microprocessor, which is supported by the Arduino Open Source software development system, and can be easily re-programmed for different tracking needs.
A hands-on TinyTracker that can be pointed at different angles toward a light source is connected to an actuator motor, and allows visitors to learn about light sensing and see how trackers work.
