The shrink-tubed constant current diode was hot glued in place. This did not affect the enclosure's ability to close. The power leads were soldered to a 1/8" (3.5mm) phone socket. After reviewing the picture it became apparent the leads were reversed. The positive, red wire, should be going to the tip while the negative, black wire, should be going to the sleeve. The wires were insulated with shrink tube. The phone socket was covered in a piece of shrink tube and shrunk. The phone socket should have been an inline model which would have connectors for wires and were intended for this type of application. The wire leads must be reversed.
Two 12mm snaps were filed with a metal rasp on one side and tinned. A 1/8" (3.5mm) phone jack was soldered to a scrap of 2-conductor wire. The wire was shrink-tubed and sealed in the phone plug case. When the other end of the scrap wires were soldered to the 12mm snaps the solder would not bond with the wires. Scraps of single conductor copper wire replaced the 2-conductor wire and and bonded well with the phone jack and snaps. The anode (A) and cathode (C) leads were labeled with masking tape. They were incorrectly labeled because the phone socket was still reversed.
To do:
CCD glued in place
Do NOT copy this picture. The leads are backwards
Shrink-wrapped leads
Phone connector wrapped in shrink tube
