the hole: first you have to add solder.
Because of the larger amount of sol-
der, it remains in a liquid state a little
longer when heat is removed so that
the pump is able to suck the solder
out. If there‘s only a little solder, it will
solidify before the pump has a chance
to suck it out.
Soldering in the pins was easy. For
the jumper I used a thin bendable wire.
You need only the solder already on
the circuit board to attach the jumper
wire.
Lastly, the resistors. Where on Earth
am I going to get these from? Here
it pays not to throw out old mother-
boards. The required resistors can
usually be found on those kinds of cir-
cuit boards; all you have to do is unsol-
der them. But you won‘t get far using a
normal soldering iron.
You‘d be far better off using a hot
air soldering station. They‘re really
not that expensive and will quickly pay
