Current project, the solar backpack MkII.
My first solar backpack was made of a 1W panel, 2000mAh battery and a chargecontroller/USB converter unit.
I made that because my iPod always ran out of power on the road and I usually forgot to charge before leaving the house.
This time I’m expanding it a bit, I got a better controller [LiPo Rider Pro as opposed to Li-po Rider] it will probably get 5 0.5W panels, but currently holds 3 panels [0.5w Solar Panel 55x70].
Some photos of the progress so far. One of the entire bag, the other with the battery and controller.
Added features will be:
* Light(white LEDs) in the straps
* Red LEDs on the back as backlight
* Dedicated iPhone/iPod connector to charge iPod/iPhone, that is to say, it will, besides having a USB port, an iPod connector cable, which is wired so the iPhone and other iDevices will see it as a legit charger
Maybe features:
* Arduino controller with some nifty features, maybe a larson scanner at the back ;)
* EL wire
* GPS
* Accelerometer could be fun
* Maybe some other stuff I haven’t thought of…
