Solar Powered Stereo v2

thingiverse

This revamped stereo boasts a larger, hinged 3.4W solar panel for enhanced sunlight capture; however, it lacks a phone charger due to size constraints. A 6600mAh lithium-ion battery ensures optimal music playtime, and the device can function both outdoors under the sun and indoors on your desk. Assembly involves soldering circuits, connecting components, and attaching speaker boxes with provided screws. Test electronics before placing them inside the housing. Adjust the voltage step-up regulator to ensure proper power supply to the amp circuit, then fasten speakers and grills with screws. Attach the hinge cap and solar panel, and secure the unit with rubber feet for stability.
