    Default Mi-am tras ceas...cu secundar

    Pentru ca toate panaramele astea de aparate de radio cu ceas nu indica si secundele, m-am apucat eu sa fac unul..

    Format indicare 00:00:00: - 23:59:59

    Montajul nu e finisat ca mi-a luat ceva timp sa-l pornesc si inca nu am o cutie

    Deoarece generatorul de 1Hz din schema avea o eroare de ~10 min / ora, i-am pus un generator de 1Hz de la ceasurile chinezesti care e destul de precis.

    Uite ce a iesit.













    si schema:



    Aici este schema generatorului de 1Hz made in china...la care am folosit un tranzistor npn si am adaugat o rezistenta de 4,7k intre diode si baza.

    Ai avut ceva de munca. Bravo pentru pasiune
    Generatorul de 1 Hz e aerian la maximum

    Felicitari din tot sufletul si sa-ti mai dea prin cap si alte nazbatii.

    E primavara si chiar m-a apucat melancolia tineretii uitandu-ma la imaginile postate de tine.
    Putini inteleg ce bucurie si placere traiesti cand iese ceva din mainile tale.
