It might seem innocuous, but this project is tailor-made for pranksters. The tiny remote control used for the project is a universal one; the Altoids tin provides a handy disguise when covertly changing the channel or volume of a nearby television. Of course, it can also be used in a much more straightforward manner, as we'll see below.
To create the Altoids tin remote control, Rowley starts with a clean, dry Altoids Smalls tin, which happens to be the perfect size for the tiny universal remotes. They usually measure around 2 inches (5 centimeters) long by 1 inch (2.5 cm) wide. Since there's space left over after the remote is inserted into the tin, Rowley cuts lengths of foam rubber to serve as filler in the tin and to hold the remote in place. Cut one piece of foam rubber that fills the lid of the Altoids Smalls tin. Put the remote in the base of the tin, with the top of the remote pressed against the top of the tin. Cut a piece of plywood to serve as a shim that will fill the void left between the bottom of the remote and the edge of the tin. Set these aside for now.
Create a template for drilling the holes in the Altoids tin's bottom that will expose the remote control's buttons by laying a sheet of paper over the buttons. Using the side of a pencil, trace the button patterns onto the paper. Lay the paper over the underside of the Altoids tin's base and drill the holes into the tin. Rowley recommends holding the tin in place using a vise and inserting a block of wood into the tin during drilling to ensure that it holds its shape [source: Rowley].
On the top edge of the Altoids tin base (where the top edge of the remote will sit), cut away a length of the tin's edge or drill two 3-millimeter (1.1 inch) holes instead. This will allow the infrared signals emitted by the remote to pass through. If you bypass this step, the infrared waves will simply bounce around inside the Altoids tin and won't affect any nearby television.
Glue the foam rubber backing to the inside lid of the Altoids tin and the plywood shim to the bottom edge of the inside of the tin base. Place the remote control into the tin base facing downward. Close the tin and you've got yourself an Altoids tin remote control. Once you expose the buttons on the bottom of the tin, you're ready to freak out friends and strangers alike as they try to figure out what's going on with the television. No one would ever suspect you.
