new idea for- 4051 as rtc project
Sat Aug 05 2006, 10:44 pm
the pitfall of this project is that as soon as the power is disconnected the the clock is reset to its
default position the reason for this is that what ever count is being generated is directly displayed rather than storing it in memory so the project can be further modified by adding an eprom to it an using i2c communication.

yes i know. as i already told you.. cost restict us from using MAX886. so if you have any other alternative using core electronics then do share it..
i can give you one hint.. change DC to ac, step up, then.. AC to DC
hope it will be helpful

for that we will have to use 6 or a2 v lead acid battery and the whole setup will be bulky and also little coastly as compared to our project

lol yes inverter but not ups coz we are on small scale. is there smthing in electronics with which we can convert DC to AC. answer is yes..
have you heard of SCRs? in power electronics? we can make use of smthing like that.. coz we are woking on very less voltage..

see there is no point in telling me how to convert dc to ac because i can give u a list of such circuits
my question is lol that do we want to jump from micro electronic to power electronic my ans is no
as we want to have solution in microelectronic only is it clear
and please dont try to explain silly things we know each other well

huh! i know but what if someone with not that much of knowledge comes and try to read it.. he wont be able to understand whats going on so its always better to explain from scratch..
and power electronics was just an idea.. that there is such things i mean such electronic component exists in power electronics. so we need to find an equivalent of that.. thats the reason i mentioned power electronics
hope you got me
