I just realized today while fiddling around with rigging a remote-on for my stereo: floating grounds are going to be a real problem in here, especially when it's raining. I'm going to have to use optoisolators unless and until I sink some grounding rods at, at least, both ends of the building. And if I do go ahead with the plan to ground the middle of the battery packs, so I have +6 and -6 VDC to work with, I'll need to fuse both ends not just the positive.
