Led display digital voltmeter
I make a led display voltmeter.I saw the electronic circuit from here www.electronics-lab.com .

Here it is the material,resistors,capasitors,diode,transformer,plastic box,pcb,switch on-off e.t.c,except the microcircuit ICL 7107 and the four led displays. Here i open holes to plastic box for switch on-off,jacks,and the center for the led display meter,and i cut a piece plexiglass for to put inside part big hole at plastic box for led display. Here i cut 2 parts for pcb (one for power supply,and other one for the main circuit),and i have put screws for pcb,and i place switch on -off,jack.
