we just add a solar panel and a LiPo – *no* expensive solar charger!Ĭut the DTR trace on the back of the board for allowing serial debugging and flashing new firmware. Adafruit) independent from the power grid just by solar power! Btw. Further more we use LUA to control the sleep mode (switching off not used components) and wake up for work – isn’t it like real life 😉 With that we can run the ESP8266 Thing and equivalent ESP8226 (e.g.

The ESP8266 Thing from SparkFun is a nice board – but first we want to get it ready for NodeMCU so we can code it in LUA language without the need of an Arduino(TM) IDE. Update: the project has now proven to run solely of solar power for 3 days/nights, that might sound not that much, but bear in mind we are running an power hungry wifi module just from a 200mAh LiPo and harvesting solar power from a tiny 0.5W solar panel … as a comparison the used LiPo would ran out of power without any tricks in a single hour. Inspired by the lander #Philae on comet 67P we started a while back working on low-power projects assuming that we do have only solar power to recharge batteries and might need to sleep during a period of time to wake up on a given event.
