Hi.
I Made a 8051 circuit, with clock.
as we discuss before, I tried to fix this.
And I Notice that when I turn on my WELLER, my circuit is
doing reset. the only connection between my WELLER and the circuit, is that it connect To the same Electricity Net.
Also I notice that the data on the clock, (DALLAS with
battery backup inside) is scrambled.
THE PS.
I should say, that i'm using a Transformer 220v -> 12v 1A
Diode bridge, 2200uf 35v capacitor, and 7805.

Any suggestions ??

Thanx & Have A Nice Day.
