I've been going through heaps of 9v batteries in my guitar effects pedals.
Bloody things still have 7volts or more in them as they hit the bottom of the bin.
So I thought, why not drain them some how.

I had two el'cheapo voltage regulators laying around I bought online for a few bucks.
So to take my mind off the looming world war three, I slapped a kit together...

Took four hours to plan this out.

While I was asleep planning, some of DaVo's fairy mates done the job for me.

I got lumped with the can cutting job.

Make a small hole in the lid for the adjusting screw -- Nanna will never notice.

Tuned the output to 5 volts...input was around 16 volts.
Device specs: Input: 3~40V; Output: 1.25~35V (adjustable); Current: Max. 3A

Now to see if it works. Me fancy multi-use battery charger with 12v and 5v USB input booted up OK and sucked those old 9 volts dry.
Who needs Dick Smith crap anyway
