ATX power supply to benchtop power supply – Part 1

As I am getting further and further into small electronics, I find myself spending a small fortune in batteries. Most. Of my projects are 1.2 to 9 volts, and I am finding these early learning stages are very power consuming. My instincts told me to check the web for some sort of variable power supply that could power all my little toys.

That kinda sucks.
