Hi
I'm not all that familiar with electronics, i know a little but i have here a little project wich i'm hoping
to find som help too in here.
1) I need to make a small voltage regulator (stepless) 3,6V to 7,4V and the supply comes from 2 Li-on
chargebel batteries on 3,7V, 1000 - 1200 mAh each, it need to be as small as possible, can it be done by just using a potentiometer in a specified resistance range, and if what range should this potentiometer have ?
2) Along with this voltageregulator, i would like to have a kind of visual measurement, that tells me how many volt the device is putting out, that could be in the best form a one digit display LED or LCD or the alternative maybe 5 LED s that when one light i turned on the regulator is at 3,6V an when all 5
is turned on its 7,4V.
Again it is important that these devices also i as small as possible
I would be very happy and thankful if anyone could help me, and even more if it would be possible to direct me to an onlineshop where i can purchase these items.
I advance many thanks
