The circuit he’s building here is a solar charger for the super capacitor. Being a fairly small device there’s not a lot of current, voltage, or energy, but these are different enough from ...

An ultra-low power sensor operates using energy harvesting from various sources for efficient monitoring. The oscillator ...

Supercapacitors (often ... to build electrodes and a high-current switch, then try welding different materials. I also want to optimize the charging circuit. I think this has been enough for ...
