Targets
The targets were designed with modularity in mind, so that they could easily be removed form the system, tested, and potentially replaced. Being completely modular, they were only connected using a molex connector and cable - enabling us to quickly isolate issues. The targets were each a small Duron pentagonal compartment, closed with screws to allow for a secure but removable lid. The LEDs were press fit into the Duron, with sheets of opaque acrylic providing support and an outer diffuse layer of sandblasted acrylic to diffuse the bright blue light. The IR emitter was raised above the other LEDs and acrylic to permit it to emit in all directions. In contrast, the phototransistor was sunken low into the target, so that IR waves would need to come from directly above it in order to detect a signal.
The center ring of LEDs illuminated when the target was active. If the user covered the target successfully, the outer ring of LEDs would also illuminate to give the user feedback that they had successfully completed that target.
Rough dimensions of the target are seen above, with a slideshow of the construction and completed targets below. Detailed CAD drawings are farther below.
