Hallo Gábor, > Anyway, frequency of the AC input is not so exact sometimes As a Christmas present I gave my parents-in-law a self built clock in plexiglas using CMOS ICs and 7-segment LED display I scrapped from various computers and other electronic devices. It was triggered by the 50 Hz of the power net. My parents-in-law live in Poland only had to adjust it for summer/winter time and for the three or four powerdips they had in fifteen years time. I learned at the technical highschool that over here in the Netherlands they run a clock on the 50 Hz and that that clock is compared with an atomic one. If a difference occures, the frequency is temporarely slightly altered until both clocks are the same again. -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
