upgrades for swiss traditional flashlights

fit a solar-charged, battery powered digilife function into an ubiquitous milspec case. for nomad use. f.ex.

• flashlight
• blinkeshit
• powerbank
• microcontroller
• wifi server
• dac
• bentobox with peltier cooling
• Your ideas..?!

SolarELVESoHowDoesThisWork?

FresnELVES

1. downloading energy with high-efficiency 5.5V 1+W solar panels 2. charge controlling 1. as close to the source as possible to avoid loss and minimize faults (a wire doubles the solder point…) 3. storing energy with 3.7V lipo battery packs 4. connecting energy drain like 6V 1W led via transistor switch

always-on

• system stores solar energy when available
• else it emits its energy
• at a rate slower than received if possible
• matching your specs carefully decides performance ultimately
