Solar harvesting into supercapacitors from Jasper Sikken on Tindie https://www.tindie.com/products/jaspersikken/solar-harvesting-into-supercapacitors/

The AEMSUCA is a 15x20mm board for the AEM10941 Solar Harvesting IC from E-peas. It efficiently converts solar panel energy into SUperCApacitor charge, it even works with indoor light. It features two regulated outputs that are enabled when the supercapacitor has sufficient charge, and a low voltage warning that informs the user of impending shutdown when the supercapacitors run low. It easily integrates in other projects because of the castellated via's, and when soldered onto 0.1' pitch header it fits in a bread board.

This board is special because it integrates maximum power tracking, supercapacitor charging and two regulates outputs in a tiny and easy to integrate board. There's is no other board with so few passive components.

A disaster-resilient communications network powered by the sun.

When the critical infrastructure that so many of us take for granted goes away, how do we organize ourselves and our communities to respond?

If recent ecological disasters have demonstrated anything, it is the inadequacy of existing models and tools to provide efficient allocation of resources, access to emergency communications, and effective coordination of human effort. Few if any solutions exist that are off-grid, affordable, reliable, easily deployed, and openly standardized.
