Materials: Sunnan Solar Desk Lamp
Description: The instructions are much more detailed on our blog post, but the basic concept is:
1. Replace the stock batteries with higher capacity batteries
2. Modify the battery compartment to accept Voltaic Systems small solar panels
3. Re-wire the lamp to accommodate Adafruit’s MintyBoost module
Run your lamp AND charge your electronics!
