Yesterday evening one more array 4×1.2V rechargeable batteries (accumulators of 3000m A/h) was added in parallel to existing identical 4×1.2V battery-array. This kept the RPi alive 10 more hours so that we have the device living about 20 hours total. But this is not enough. The goal is several months or…
Video_01_ENG Video_02_ENG Video_03_ENG Video_04_ENG Experiment Goal: To enable the following features: – auto-reporting of keep-alive starting at power-up – creation of a prototype of potentially ALWAYS-RUNNING RPi powered from batteries that are recharged from solar energy This will allow future stand-alone GREEN projects Experiment Description: TBD Components: – 1 Small Solar Panel producing about…
