Ruski C/ESR metar
#46
U prilogu precrtana shema i izmjene koje sam napravio su sljedeće:

- dodao kod svakog OPAMP-a 22uF/16V elektrolit i 100nF blok kondenzator
- dodao kod PIC-a 22uF/16V na Vdd pin koji je paralelno sa 100nF blok kondenzatorom
- kod ICL7660 na CAP+ i CAP- izmjenio sam sa 15uF na 10uF elektrolit iz razloga što je 10uF lakše naći
- izbacio sam sa sheme ICSP konektor za programiranje jer će PIC ići u DIL28 pa pošto će se programirati samo jednom (jer ima zadnji HEX na ruskom web site)
- dodan otpornik za backlight LCD-a 15R za pozadinsko osvjetljenje (imam doma ERM1602-2.1 LCD pa sam pin 15 i 16 spojio prema datasheetu)

Schematic ERC ne javlja nikakve errore pa ako je sve OK (alarmirajte ako nije) ovaj mjesec bi se posvetio designu PCB-a za ovaj odličan rusko ESR meter koji pored ESR-a mjeri i C.

Pošto imam na kućištu veliki button njega sam mislio iskoristiti za ON/OFF (jer će unutar kućišta biti 9V baterija) pa me zanima sklop koji jako malo troši u stanju mirovanja (da se sačuva 9V baterija čim duže) i da radi po principu jedan pritisak ON, drugi pritisak OFF...poželjno sa nekvim mosfetom u TO92 kućištu ako može shema da je dodam na ovu i time bih shema bila kompletna.
