Capacitor-frequency meter
I make a Capacitor-frequency meter.It measurement capacitor from 100 nF - 13.000 ìF,and frequency until 30 ÌÇÆ.The circuit i saw from the Greek electronic forum www.hlektronika.gr .
| Here it is the material,resistors,capacitors,diode,plastic box,pcb,battery box,Jak,many-cable e.t.c,except yet the microcontroller(pic-16F873A),and one SMD (FDS6680 AS). | Here i open holes to plastic box for switch on-off,push button,jaks,pcb,and the center for the LCD display. | Here i have put screws for pcb,LCD display,and i place switch on-off,push button,and 3 jack. | ||

| Another one view from top side. | Here i put from down the plastic box side 4 little sponge . | Here with base soldering iron at low temperature 280 c ,i will connect the many pins jack at LCD display,for to connect with main unit. | ||
 |
 |
 |
||
| It is ready. | Here with soldering iron i put the many-cable to pin jack,for to connect the main circuit with LCD display . | Here it is ready . | ||
 |
 |
 |
||
| Here i programmed the pic PIC16F873A with this USB programmer.. | Here it is ready the compontents with soldering iron. | And from the other side. | ||
 |
 |
 |
||
| Here it is absolutely ready all the project . | Here i make a test a electrolytic capacitor,down it is the last project semiconductor analyser | Here i make a test a electrolytic capacitor,down it is the last project semiconductor analyser | ||
