I got several odd items. ;D Whu not build an DIY ? I am currently designed an discrete ckt. There may be some fault as I have not cross checked. however, though this is designed for 2 cell, 3 cell and 4 cells can be easily made with the common circuit block. Only thing is that, biasing resistance for 548 will be 3k, 4k ... for higher series cells. As I cannot find ready-made buzzer simbol, so replaced with a bulb. All LEDs are of dual color LED as they will save space. And that is why the circuit designed inverted, i. e. PNPs as sensor. 2.7 volt zeners are criticals and you may use 2.2 volt, but the pots are need to be adjusted. An fault in drawing, Cell voltage have not been changed from 12 volt. Actually they are your test cells. Title: Re: Needed a small item from hobbyking worth $1.92 Post by: dhaksha_dx on December 10, 2011, 05:26:05 PM anyone help guys
