[jcopro] took a look at a Glade automatic air freshener he had sitting around and couldn’t help but open it up to determine how the mechanism worked. After taking it apart, he found that the automated system was comprised of a 3v motor, a series of gears, and a mechanical arm. When actuated, this arm simply pressed the spray nozzle of the air freshener canister contained within the device. After some consideration, he decided that the components would make a great remote trigger for his Casio point and shoot camera. He fabricated a small plywood rig including both the camera and air freshener components, which was able to be mounted on a tripod. [jcporo] also mentions that the air freshener has the ability to be triggered by a built-in timer. Although the presets are locked at 9, 18, and 36 minutes, he suggests that a 555 timer could easily be used to add some custom timing intervals when wired to the manual trigger. Be sure to check out his video of the remote trigger in action.
