Solar Notebook Charger

SolarNotebook2_WM3[20170125] NEW version of Solar Notebook Charger 2.0.  the new version was inspired by the fact that we ran out of the solar laminates we had for the first version. So we’ve custom fabricated 6v*500mA solar modules for the new edition, and are inspired to repurpose corrugated plastic campaign signs for a waterproof and durable notebook material.  We’ve created 2 options – 2S = soldering required. 2NS = soldering NOT required.   For the soldering option, students will solder solar modules directly to the USB charger, eliminating the need and cost for an autosocket.

The ‘Notebook’ (version 1) is similar to the Zipcharger, but uses 4 solar laminates to increase current required by newer phones (eg. iPhone 4 & 5). Instead of a zippered wallet, you get creative and build a ‘notebook’ made of cardboard and duct tape to house and protect the solar laminates. Make sure to extend your creativity to designing the cover – make a collage from magazines (solar, nature, eco) to develop a cool design with a message.

[August 23, 2014] Sacramento Teachers build Solar Notebook Chargers at Solar Primer Workshop
Thirty teachers gathered in Sacramento at SMUD Energy Technology Center on recent Saturday to learn how to integrate solar energy lessons into their classrooms.  They also built solar cell phone/mp3 chargers using cardboard, duct tape, and solar cells.  The Notebook chargers provide a practical application for solar electricity – charging the battery on your mobile device using only the energy of the sun.  Educators also built a small motor-driven whirlygig – a kinetic sculpture – that when powered by the solar notebook, demonstrates how solar cells work.   Solar Notebook Charger Kits are available from Solar Schoolhouse (Rahus Institute).
