Power resistor or voltage regulator?
Anyone a simple diagram?(if i need one)
Draw is about 1A but i would like to have some tolerance.

Looks like i have to answer my own question again, but this is something the
entire group can use.
Some cool stuff there:

a pretty good site (but everyone here has probably seen it before).
A resistor would work if the current draw is fairly constant, but 3
terminal voltage regulator (LM7809 eg.) is better. circuit is regulator and
wire...
