i have already postd about my solar cell of 5.5v and 60mA.since that post got dead because of me not respnding in time so i have started a new one. i want to charge ni-cd/ni-mh batteries . i want o biult a solar charger a simple one which works like this.
i connect 3 batteries to my solar and cell and want some type of switch that would trip when the voltage across it is 3.6 volt. that way it would close the ckt and an led would be connected in series with the 'switch' to indicate that charging ahs been completed. i want to use passive components otherwise there would be no use of chaging the cells wehn you are using them in the proposed charger. i tried a zener and a schotky but to no vail since when i connect them in parallel they trip due to the full o/p of the cell.any way to circumvent this problem!!!please
