    I need some advice

    ahhh i'm fed up with it lol, i've resoldered as you drawn, changed the ni-mh batt, now i just hope it'll work out.. thanks lot for all the help you guys have given, much appreciated.. i'd probably be gone for a long time now.. *off the aussy for furthur studies*

    I need some advice

    okie, but it doesn't make sense, the circuit as you drew i had 1.7v between diode and gnd ( with or without timer) but 1.2v with the battery parralleled the orignal timer only requires 1.2v button battery at 1.7 v the timer is disaplying normaly, this is really making me confused...

    just incase the batterry might be the hge problem, its ni-mh 2100mAh, hr15/51 1.2v hr6 migon AA

    I need some advice

    with the added resistor the output A went from 3mA to 28 mA ( chanegd the battery on my fluke if my earlier recrdings were somewhat puzzling) the battery seems to suck all the power

    I need some advice

    ah krap 1 hr after i soldered everything the clock went dead i redid the circuit and follows excatly as you drawn when i put the battery on and waited a few mins, the clock slowly fades when i reduce the 56 ohm resistors, the clock didn't come back up ( i did this by parraleling the 56 ohm...

    I need some advice

    minor problem, which confuses me.. V-drop across diode is 0.4 to 0.5 my circuit is as so 3.125V - 99.7 ohm - 56 ohm - GND -------- 2 Vs-------1.13v---- i had the diode placed at vcc gnd* here is the mid point between the two resistors 3.125V - >| - LOAD - GND* ( with battery )...

    I need some advice

    okie got that, time for bed i shall re do the circuit for the 4th time lol,,, thanks alot i see how well it goes tmr..

    I need some advice

    wahhahahaa i dun believe it i went to try again this time i used crocodiles clips, its now displaying correctly, lol then i stick my finger on the contact it jumps up again.... SOME conductor i am . wth....... must i use the said diode or any other diode i can find ? just pondering, the...

    I need some advice

    sweet, i think i understand abit more now , my 1.2 altho is enuff to run the timer won't be enugh to chareg the battery. , the last i checked after i did my version of the circuit i had 1.3 across the 50 ohms , i paralleled the timer and the batt on it, if my calculations were correct i had...

    I need some advice

    okie i found the lower resistors now, i have R1 on 50 ohmz and R2 aprosimately 100 ohmz,, will these work better now ?

    I need some advice

    btw where can i find this datasheet ? thanks

    I need some advice

    so thats like in the best scenario , 0.025 current over a max of 20 hours or "heck care about the battery life" (like those in cordless) it still last for more then 2 yrs under constant charging.. if i reduce the resistance of my circuit to R1 = 100 and R2 = 200 i'd get abt 1/80 C would...

    I need some advice

    you mean the non digital types? i did thought of that,. but, then my modem would be shutting down every day..and for atleast 30 mins give or take 10mins, the one i had only had about 48 legs..
  14. B

    I need some advice

    if i remove the R1 resistors and short in the battery instead, would this be advisable ?, since i tried for a brief time the voltage would stablise at 1.3 to 1.4volts, but this means the batt is constantly charging, would prolong charging in this state casue damage to this battery ?
  15. B

    I need some advice

    what kind of diode should i use and how should it be placed ?
