The idea of this project was to design a motion-detector that is able to hide one’s activity on a computer. There would be a transmitter (TX) and a receiver (RX). The user would put TX in the path of an incoming threat, and plug RX in their computer.
Once motion is detected by TX, it should talk to RX wirelessly, which would then act as a USB keyboard and press a key combo to cover user's track. This can be minimising all windows, locking the computer, or executing a custom script.
The product should also be as small and easy to use as possible, with a long battery life.
I feel that this project has great potential, because:
- The idea is interesting, novel, and unique. I don’t think anyone has done it before, but it’s certainly worth doing.
- The project itself is rather challenging, involving low-power systems, wireless communication, RF systems, batteries and charging, miniature design, and manufacturability considerations. All in all lots of stuff to keep track, should be a good learning exercise.
- The finished product would be very practical with obvious commercial potential. Surly every office slacker and teenager doing unspeakable things in their bedrooms would want one ;)
