David Graham writes: "Recently, I incorporated a wireless camera into an HO scale 74' passenger car to make a TrainCam, and this is the story of its construction.
Lacking space to build a set in my rented single room, I built a simple 18" radius track on the carpet, going through the frame of my bed. On it, I added a short Amtrak train and watched it go in decidedly boring little circles. Not long after I started running the train, it derailed and clearly demonstrated why carpets are not the best place for model trains to be. Meanwhile, upstairs in his room, one of my house-mates had just bought a small wireless camera, battery pack, and receiver for a little over C$100 and was demonstrating its ability to broadcast conversations and images from as far as 200 feet away back to his computer screen, with the help of a TV capture card. It wasn't long before I started coveting the little camera and I soon bought myself one. It was not for the purpose of listening to my friends' conversations so much as it was to record the train as it chugged around the uneven little track on my floor."
