I was wondering If I could use a radioshack power supply to make a safe working LD.
I don't want to build a regulating circuit so I was wondering if I could use it instead.
I have a 12volt dc power supply from radio shackand it reads exactly 12volts.
so can I use a 3 volt supply with a certain amound of ma for a LD?
if so, how many ma?
