Ruski C/ESR metar
#54
Ostavit ću BS170, jest da je 5ohma RdsON ali to sve skupa troši 3mA cijeli sklop, pa mislim da nije to toliko kritično s time što LCD backlight troši oko 20mA...računao sam cijeli sklop troši sa svime 45mA, tipične 9V baterije u dućanu imaju 550mAh, što daje čistih 12sati korištenja instrumenta ako je non stop upaljen. Više nego dovoljno (DMM isto koriste 9V bateriju pa traju i traju jer nisu upaljeni 12sati non stop). A u standby sklop troši 12.1uA što je zanemarivo malo. Tako da će baterija od 9V dugo potrajat.

Shemu sam malo modificirao...dodao sam GND na 78L05 a maknuo GND sa BS170, iz razloga što je GND sa baterije spojeni direkt na BS170, i kad on provede spaja taj GND sa baterije na GND 78L05 i sve proradi kako treba. Svi GND su spojeni na jedan te isti GND, tako da je to sada kompletno, a 9V od baterije GND nije nigdje spojeni osim na BS170 koji preklapa tj spaja taj GND sa baterije na GND 78L05 Smile

Dakle BS170 je preklopnih GND-a Smile

Evo upotpunjene sheme.

Zanima me još ICSP, zašto se korisit jumper? Zar nije lakše otpojiti bateriju, da komplet nema napajanja, spoji se ICSP preko 5-pinskog konektora na PIC Kit 2 programator i programira, nakon završenog programiranja otpoji se ICSP konektor, ušteka 9V baterija i sve bi trebalo da radi...nije mi jasno zašto je dodani taj ICSP ako moze po gore navedenome da radi.
