experimental infrastructure
Thursday, July 9 2009
I still hadn't quite shaken my fascination with the Panasonic DECT 6.0 phones, particularly given the amount of experimental infrastructure already in place. Today I took the most suspect of my two extra base stations and removed some sort of three-terminal semiconductor connecting its final RF stage to its two on-board antennæ. I then took the signal from the RF stage and sent it through coax to the laboratory deck. Checking the handset range with this setup, I found that most of the signal was still being generated by the base station. Evidently it was leaking out from the imperfections in the places where I'd soldered the coax (core and shielding) to the base station motherboard. I didn't notice much of a signal from the distant end of the coax. The magic involved in getting this stuff to do interesting things continues to elude me. Unfortunately, I have found no evidence of anyone else experimenting with DECT 6.0 equipment online. It's relatively new (only reaching the United States 2005), but that's no excuse. (I myself, hardly one to jump on new technology, was doing web stuff when the web was only a year old and publishing on it when it was only two years old.)
In the evening, I spent some time painting the exposed wood surfaces (pretty much all the wood on the outside except the plywood under the east and west roof overhangs) using an expensive olive-drab paint I'd bought to darken the shiny galvanized steel of the roof. The mosquitoes were relentless, taking advantage of the fact that I'd be reluctant to smack random parts of my body with fingertips covered with paint.
