Well, I finally got around to finishing a project that has been laying around for a few weeks. These tins are just the right length for stacked 16340s, so I gave it a try. I used a squared off piece of PVC to mount the switches and protect the components. The circuit board with a 5v regulator gets covered with electrical tape after the photo.
Thanks to Connman for the Eclipse tin idea and, though I didn't realize it until just now, the 5v regulator diagram on madvapes site as well.
