solar backpack charger
I'm leaving in a week long MTN. Bike Tour. Wondering about schemes for solar battery charger digital camera?
I to be in the country again, so do not have access to electricity. I have a flexible solar panel that can hang on your backpack. Looking for control circuits he may now charge a point and shoot digital camera battery. My matrix is 1x2 and takes 12 volts and 400 milliamps to full output about noon. I designed and welded a regulator to regulate at 6 volts. But I need something better and more precisely regulated. The battery is a 3.7V Li-Ion with a capacity of 1700 mAh. Thank you!
This site has a good track to do what you're looking for, although it requires a supply of 6 V. I suggest you either modify your wiring solar panel that the results of 6 V (half of the elements in parallel with the other half?) or continue to use the controller you already have.
