This day I think was the hardest day of the project, because we have to be careful on the connection of wires. First, we putted holes on the front and back of the case, then we move on to the connecting and soldering of the wires on the switch selector and on the transformer.
To start this, we connect the wires of the selector switch We skipped the "zero volts" then connect the remaining volts of the selector to the diodes ; because its more complicated we have taken much time on it but we manage to finish it. Next is the Wires for the on/off switch and for the wires in the transformer and for the terminals, this is more simple than the first one because it has lesser wires to be soldered.
-Input = 220v
-Output = 4.5v
-3v connect to 3v feet of the transformer(output side)
-4.5v connect to 4.5v feet of the transformer(output side)
-6v connect to 6v feet of the transformer(output side)
-9v connect to 9v feet of the transformer(output side)
-12v connect to 12v of the transformer(output side)
We solder it after connecting the selector to the transformer.
