#news from 02013: “long endurance, transoceanic gliders harvesting all energy from the ocean thermocline,” the so-called #Slocum-Gliders, contracted by the Navy of the #USA to Teledyne Benthos. #underwater #drones #energy-harvesting
on 02026-04-22#video on Nordic RF #communications #electronics that can feasibly run off some largish photodiodes used as solar cells. “Ultra low power energy harvester from BPW34. Super small and durable power supply for wireless nodes” on hackaday. Also “Solar-powered flashing LED heart pendant PCB coil” by bobricius in 02018. This guy, "Pocket Concepts", got 300mV out of his BPW34 photodiodes, and used it to transmit a temperature datum over #Bluetooth #BLE to his motherfucking phone. His #Nordic chip uses about 50μC of charge (over the 2.25V to 3.6V range) to run for the necessary 20ms, so he needed 37μF, which looks like maybe it’s a tantalum cap. It gets enough power from his fridge light to send a transmission every few seconds (so, say, 0.4% duty cycle, so he’s getting tens of microwatts). But a slightly larger amorphous cell is even better because it works even in a dimly lit room. #electronics #solar #photovoltaic #energy-harvesting
