The schematic for the project was updated to show the button which will, hopefully, control power to the device. Yesterday a file was linked but that file has been replaced so downloading from the link on either page will provide the most current schematic. Links will be provided this way to always provide the most current data when it is given through links. Old versions of programs and drawings will not be available through this site so it may be wise to read through an entire project before attempting to duplicate the results.
A segment of 1" schedule 40 PVC was cut to 5 3/4" (145mm). At first the piece was cut longer but the final size was 5 3/4". This size was based on the internal area of the flashlight from the bottom to the top where it would leave enough room for the electronics. A bandsaw was used to cut a channel in the pipe so a 9V battery would fit into the groove. Unfortunately a bandsaw made uneven cuts so the edges needed to be sanded significantly. Sanding was done by wrapping abrasive paper around a thin board and moving the pipe over it.

Sanding the pipe on the internal cuts
A 3/16" (4mm) hole was cut through the PVC and flashlight. The PVC was angled so the drill would catch plenty of the pipe. It was important to cut the hole near the switch since it may be necessary to tighten the #10 bolt going through the holes to keep the button near the switch. A suitable bolt could not be found at the hack space.
