Solar powered charger for small electronics such as mobile phones or portable music players, with carrying case made from a book. The charger is an Instructable and consists of: Minty Boost kit from Adafruit Industries and additional parts from Spark Fun.
Needed a hinged case to house the components - wanted to add warmth to the cold components, something which naturally would not short out the circuit or heat up easily and be a simple form factor (the original project suggests an Altoid tin).
Technique inspired by the Burroughs and Gysin cut up method, aesthetic derived from A Humument by Tom Phillips (an artist book created from a Victorian novel).
This project was a true lesson in materials… slow going and things broke and needed to be repaired. Humbling. And I have yet to fully understand it from a solar energy perspective.
