Power Supply for My Cordless Tools 2

In my previous instuctable about the power supply (PS) for my cordless tools I explained how I build the unit. However, there was a problem, the PS would run perfectly driving an 18V drill but would switch off with circular saw or reciprocating saw. Two of my Youtube cnannel viewers suggested to connect a capacitor and so I did. Now I have a fully functioning power supply that is capable to drive the whole range of 18V Dewalt tools.
