If you have read my recent posts on golf, you will know about my electric golf trolley battery woes. To cut a long story short, before I send the old 12 volt battery to the recycling depot, I wonder if there is a way of using it to power my FX pedals on the pedalboard. I measured the open circuit voltage and it is 13.15 volts. Is there a box to drop the voltage to 9 volts? The new golf trolley battery purchase has delayed the purchase of a Voodoo Lab Pedal-power 2, this might be a way of killing two birds with the one stone! Thanks.

I use a board like this (not this exact one but one since mine came from China but this one looks pretty much the same) when playing with "sag" voltages on my breadboard:

I confess I didn't pick this design very scientifically, I just picked one with big caps on it (reasoning that the resulting supply would be less noisy).
If you want everything properly isolated you'll need one of these per-pedal but I'd buy just one to start off with an see if it sounds OK first!
