The ETOW HL1-FR HumanaLight is an amazing light source kit. It was developed by the Ears To Our World nonprofit organization that specializes in the distribution of self-powered world band radios and other appropriate technologies to schools and communities in remote, rural and impoverished regions of our world.
Reliable electricity is still not available to 25% of the world's population. This simple light source is powered by a single AA cell (not included). And how long does it last? Not 5 hours, not 5 days, but up to 5 weeks! The simple (... yet magical!) circuit dramatically extends the life of the AA cell. Using a Joule-thief circuit, the HumanaLight pulls power from an otherwise dead AA battery and renders it useful. Very useful if you are in the dark! You can insert a seemingly "dead" AA cell, and it will light for days.
Another benefit of this item is that it makes a great first soldering project. And when you are finished you have built a useful device.
A third benefit of this item is that it helps support the great humanitarian work that Ears To Our World is doing worldwide.
All the parts are supplied.
