charging four 1.5 V cells using,

[Col Sanjeev Devasthali]

hi, can anyone suggest a circuit for charging four 1.5 V cells using,
say a bicycle dynamo. planning to make a contraption to drive a
miniature turbine using power of small waterfalls along trekking routes

in mtns. then to use these btys to power LEDs for tentage lighting.
thanx.

This could be done if you can get the generator to spin. All you need is to
keep the voltage and current suitable for the batteries you choose.
But I personally wouldn't carry a water wheel with me when products such as
this are available:

hi, this is more for gifting it to the locals there, who can then
harvest the natural resources like small little waterfalls/ winds to
their advantage. thanx.
