The board did not sit nicely against the round pipe. Tightening the screws drove the component leads into the pipe but it seemed sturdy. Since the light strips sat high off the pipe, it was difficult to attach them with the adhesive. Perhaps the next model of sensor board should have solder pads which can attach directly to the strips. It would also be possible to model a piece which would act as an adapter for the sensor board and pipe and even provide a ramp for the LED strips.
Wire color codes were recorded for one tagger and the same will need to be done with subsequent taggers. This was necessary since none of them were assembled at the same time or with the same wire color coding. If they had all been assembled at the same time, it would be more logical to have a single color code which spanned across all the taggers.
Sensor boards and light strips were attached to the shortest tagger. This one was assembled as a test to find out what worked well and what worked poorly since the short tagger was the least important. Its size also makes it the most difficult to assemble which would be important to know for future builds.
