Electronics of Master Clock for Slave Clocks

Big old wall clocks that were used in facilities such as schools, factories and hospitals are very appealing and will probably never go out of style. They are very durable and almost never break down due to very simple mechanism they have.

This mechanism is actually pretty simple, it is just an impulse motor (two coils) and a couple of gears - no further complications. This is a blessing and also a curse for these antique clocks because for their operation they now require something called a master clock. Master clock is an electronic device that sends pulses to these slave clocks so that they can work.

Postovani, pokusajte dodati otpornik 470K do 1M paralelno kristalu ili malo povecati vrijednosti C7 i C8 sto dalje moze uticati na tacnost, takodje provjerite odabir vrste oscilatora prilikom programiranja mikrokontrolera... Pozdrav.

Pocituvani prijateli, pocituvan author projekta ELEKTRONIKA MATINOG SATA, Izgradio sam elektroniku maticnog sata tako da umesto kristala od 131.072 KHz sam upotrebio kristal 32.768KHz. Moj prijatelj je preradio asm cod, programirali smo PIC, ali oscilator radi samo kad strafcigerom dodirnem pin 15, na samom kristalu. U ovom slusaju uredjaj pravilno radi i dobijam treperenje LED-a na svake sekunde. Kad prestanem sa dodirom, uredjaj radi jos nekih desetak sekundi i opet prestaje. Pomozite mi kako da modifikujem uredjaj kako bi kristal lakse startovao i da proradim uredjaj. Nisam mogao nabaviti orginalni kristal pa zato sam upotrebio 32.768 KHz.
