Well,
I decided to give my barrel another cleaning after I did the battery thing the other day and fried the batteries and the flashlight.
I built a low voltage power supply from a bunch of spare parts I had hanging around. It's just a 5 volt regulator and it's powered
from a hair dryer transformer that put out 9V @ 300ma. I think I need to get a bigger transformer though.
Anyway here are a few pics from my day trying to get this barrel sparkling clean.
My home made 5V power supply.
The surplus hair dryer transformer and my jar of cleaning fluid.
My Setup (the camera glitched on me)
The first pass. I did a second pass and got little, if any, crud from doing it again. There was quite a
bit on this pass. This is just what bubbled up into the funnel.
A few dozen more attempts and this bore might be sparkling clean. As of now it's not too shabby.
