Today i was bored so i put together a little light thing in a 3.5" floppy drive bay. Its pretty basic, just 5 LEDs (just dodgey ones we use at school in electronics that ive collected over the years) a switch, and 9V power conector thing for a 9V battery. The only problem is its not gettin enough power from the 9V batery. The circuit all works fine but its not gettin enough power.
The LEDs are 1.5v so ill need atleast 7.5v to run them all. Or alternatively is it worth just rewiring the whole thing so the LEDs are in paralel, not series like they are now.
my question is, how much power goes through the computers power cabling (eg. cable to a fan) and also if its safe to add in a circuit to that power suply.:? :? :? (probly by splicing & heatshrinking the wires)
All help is apreciated because i dont want my mastepiece to go to waste.
