UPDATE: The project is complete have a look at everything here. Nerf Gun Hack part 1, part 2, part 3

This is the final part of the Nerf Gun Hack. Check out part 1 which goes over the how the chosen gun works and part 2 which goes over the electronics used in the project. This time a completed perfboard version of the project is built and the system is installed into the final setting. As you can see the gun is mounted into my daughters music room and the gun is hidden amongst some of her dolls. The IR Transistor and IR LED is mounted to one end of the wall unit and a table leg. The IR beam that is created is just past the entrance of the room, far in enough for the door to miss it. When you walk into the room and break the beam the gun will fire directly at you. My daughter hits the floor in the video but don’t worry, she is a good actor… These foam darts don’t hurt. 🙂 There is a quick schematic in the picture gallery below, it is hand drawn so hopefully everything is legible.
