First light probe construction (almost) finished
Lots of progress on physical construction, and much better insight on what it will take to finish.
I've now finished constructing most of one of the light probes. It was pretty straightforward, most difficult part was rounding off the stems on which the lights and sensors are mounted, so that they will meet the trunk seamlessly. I have to say, Dremel tools are great. I was basically using it as a sculpting tool, to cut and grind pieces of wood to fit exactly.
Next steps are to run the wires through the black vinyl tubing I picked up ages ago, and connect to the circuitry inside the main gourd. Other than filling in some gaps with putty, and hiding the screws, that should be it.
The next two probes are likely to be simpler, relying on a single vertical mount for the sensors and lights, as in this picture:
The circuits are mostly assembled and tested, based on the (successful) design for my "Action At A Distance" project, but with considerably more elaborate software (and sound).
