But the problem as i told you is in the charging circuit. my circuit of 7805 regulator is not supplying current more than 17mA. that's why i am asking here that what could be the problem?
actually i yesterday i did not had them but today i did add both the capacitors But still the charginig current is 17mA and NOT going up or down. i thought it mayh be the problem of bad 7805 regulator and i changed the regulator But the problem is still there.
the output of 7812 ic is 11.90v. you think that i ishould you lm317 instead of 7805? and i should not use AA batteries to power the circuit. is this what you are sujjesting me?

and as i said that i checked the...
the charging circuit in the mobile phone is working fine Because the original charge of the mobile is chaging it in the normal way. may be problem is the input from 7812. if i put 4 AA battery instead of 7812 output. will it work?
today i tried up with 7805 regulator. But after all this the circuit is not charging my nokia 1100. i checked the voltage when charging, it was exact 5v and then i checked the current unfortunatley i know why the current is not going above 1.7mA. what could be the problem? i am powering this...
Thanks for your replies.
i want to try Both. i have the above one that would give 3.7v at its output. can someone give the schematic charger that deliver 5v.
In above circuit i am still confuse about BCP68-25. is it the transistor number. can someone give me the replacement of this transistor...
:-)
I have Nokia 1100. But a standard charge come alonge with nokia mobile is able to charge every mobile that belongs to Nokia. i did it experiented. some get charge slow and some go very fast. the links i posted in my first post will the mobile But as ckshivaram said that these charges will...
Hey! audioguru that's not fair. atleast he is helping. send me some good schematic please to charge my nokia mobile. please send me a good schematic.
Thanks
