Improvements
Better Box- We believe that we could have made an extremely compact and light-weight design project. The actual chip and circuitry takes up very little space. With accurate soldering and ideal parts we could have made the project 1/8 the current size.
Stronger LED- The remote controls we have been using to program our device were detectable by our IR receiver 5 ft away from 90 degree angles, the LED had to be within 10" of the receiver and directly in front of it.
Research- We should have done more research on the tolerance of cable boxes. We don't know how exact the replication of the signal has to be. We also assumed that we could generalize from only 2 remotes that behaved similarly. It turned out that a 3rd cable box remote has different characteristics if you hold down a button then the other two remotes have.
