Mysoltrk solar panel Sun tracker Mysoltrk operates using a set of two straightforward, yet sturdy actuators, each one constructed around a 6V 30RPM geared DC motor.

A 3D printed case holds the e-ink display and encloses the inner workings, driven by an Arduino Mega 2560 and powered by three lithium-ion capacitors (LICs) and a small solar panel.
