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 |
