[Rusdy] is building a solar charger for his electric bike, and quickly realized the lithium cells in his bike wouldn’t work well with the most common charge controllers out there. Solar cells have an ...

According to the most recent data from the World Bank, 15 percent of the world’s population—approximately 1.1 billion people—lacked access to electricity in 2014. In 1994, approximately 27 percent of ...

This Low Dropout Voltage (LDO) solar charge controller is a variation of the previously posted 12V LDO controller. It is optimized for charging a 6V lead-acid battery with a 9V solar panel. Minimum ...

Green hacks implement one of two philosophies. The first is über-technical, with very expensive, high-quality components. The other side of this coin creates green power out of junk. [Timot] obviously ...

This Low Dropout Voltage (LDO) solar charge controller uses a simple differential amplifier and series P channel MOSFET linear regulator –their compatibility seems like a marriage made in heaven.
