> 2) Are there other CHEAP solutions for low current consumption? Yes, and accurate over long periods, over moderate temperature ranges (unlike a basic 4060 solution) http://home.clear.net.nz/pages/joecolquitt/lowpower.html With the PIC in SLEEP and waking up for a very short time every 2 seconds you should get a year from 4 AAs + 1 AA for the timer module "cheap" is subjective. You can get a clock for a couple of dollars, definitely less than you'd pay to make your own temperature-compensated oscillator. More than you'd pay for a 4060+crystal+R+C though -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.

Hi Jinx, I have seen the web page. Good idea: yes, is "cheap" also for me! Probably there is less consumption than 4060 + 32Khz crystal solution. >>over moderate temperature ranges.. Will be necessary a test (i'm going to crash my chitchen clock..): however, is interesting. Thanks for the suggestion. Marco {Original Message removed}
