Making an e-Vest (electronic vest)
Added Jun 1, 2010
As a first project, I decided to construct an illuminated scene that could be worn on the back of the vest. My idea was to build this as a replaceable scene, so that I could replace the scene at the back with another scene at will. In order to achieve this, I came up with the following design. Essentially, the fiber optics cable is installed on a cloth panel that is snapped onto the back of the vest. The batteries, on the other hand, are built into the vest itself, along with an on-off switch that would allow me to turn the scene on or off at will. The current is passed from the vest to the panel through its metal snap fastenings. To begin developing this design, the diagram shows the placement of the metal snap fasteners on the back pattern piece. I planned on three snaps on each side, two at the bottom for carrying the current, and one at the top which is used uniquely for attaching the panel to the back of the vest. For the fiber optics cable I used, I needed the positive and negative wires to be placed fairly closely together. Potentially, for other applications, the wires could be separated and one could use the top snap fastener combined with one of the bottom two to carry the current. Both are possibilities with this design. Shown on the diagram, in addition to the three snaps, is the outline of the panel that will be snapped into place. Note that the panel, like the vest back, is folded along the center back line.
