I've been filling holes and repainting and it'll take a few weeks to put it into usable laboratory condition - there's even a carpet in there! That definitely has to go, but I'll do that once the painting is finished because it's a handy splash-catcher at the moment.
I can try bigger devices here than I could in the poky little lab I had before. I have an idea for a motion detector based on illuminated threads. The infrared detectors people normally use only sense body heat - and I don't think the dead have all that much body heat. I'm going for movement in actual physical objects instead.
The best thing about this new lab is that when you go outside, you don't see grey buildings, traffic and crowds. You see this:
Well, okay, it'll be more attractive in the spring, I'm sure.
The lab is, as far as I can tell, completely free of any form of ghostly activity. It's not a new building but it's away from any towns or settlements as far back as records go, so there's no reason to suppose there'd be any haunting there. Which is good, because that means the place acts as a control. Any response from any equipment is very unlikely to be a ghost and is therefore most probably an artefact. So I can tune those out.
The only downside is that the Italian restaurant that does particularly good espresso is now a long way away. I'll just have to invest in an espresso machine. I wonder if I can write that off as essential lab equipment?
