Step 12: Wrapping it up
Before mounting the board you need to do some work to the tin. Cover the bottom of the tin with electrical tape to prevent the board from shorting out on the tin. You will need to drill a couple of holes in the side so that the switch and LED are able to stick out. Use a 1/8" bit for the LED hole and a 1/4" bit for the switch. You'll need to drill 2 3/16" holes side by side for the switch and cut out the metal between them. The holes will need to be placed about 10mm up from the bottom of the tin. The LED hole should be about 18mm in from the back of the tin and the Switch holes will start about 22mm in from the front of the case. Drill the LED hole with a 9/64" drill bit. With the holes all set place a few dabs of Hot glue in the bottom of the tin and place your board into the glue.
So there you have it a nice little FM Bug Detector you can use to find FM Bugs. The antenna can be stored in the right hand side of the tin and pulled out as needed. Pair this with my FM Listening Bug and you have a fun little electronic hide and seek game.
In the future i hope to have full PCBs made up so i can start selling these kits.
