Solar Batter Charger

thingiverse

A tiny solar system comes together to power a small battery or device via USB. To get started, gather the following: * A charger or device to charge directly * Six small solar components measuring 30 x 30mm each * An adjustable step up/down component Optional items include: * A USB electronics component * A USB to micro USB cable * Series of resistors instead of the step down component Now, follow these steps: * 3D print the top, bottom, middle, and one top piece * Solder all wires from cells together in series * Connect wires from the first and last series circuit to the step down component * Solder the drop down component to the USB component * Connect to a load and soak up some sunshine! You should now have 15 volts and 900ma at your fingertips! This project serves as a starting point for creating something more specific within the container space, tailored to your needs. Enjoy printing it! If you have any thoughts or would like access to the original source file (.blend), please get in touch. Need more power? Consider using rechargeable batteries and/or adjusting the circuit to suit your desired voltage and amperage requirements. Last updated files: August 17, 2018
