![]() Every since I became involved in Rocketry I’ve wanted a system for photographing the ground from the rocket. At first, this task seemed daunting, but really, it is quite simple. If you are going to do this, make sure you have some sort of recovery system so that your whole apparatus doesn’t get destroyed when it careens into the ground at sixty plus miles per hour. Here is the list of things needed: Kodak (or similar) camera that uses 110-type film. Hot glue Small screwdriver set. 1-˝ feet or more of dental floss or monofilament 110-type film A rocket to mount all this on A “Tommy timer” * Common sense *Note: “Tommy timers” can be found in those cheap toys that one can get from fast food places, you can wind it up and it will slowly unwind, making a loud annoying noise. Start by striping the camera, by this I mean taking off the casing and the flash assembly and cutting away all the unnecessary plastic, so that it is as light as possible. You will need to locate a few things before going any further, one is the spring-loaded lever that pushes the shutter open, the other is the film advancer (If you are an expert on camera’s please feel free to correct these terms, the e-mail link is below). Now, cut a small slit in the plastic knob that you twist to wind up the timer and glue one end of the floss in the slit. Glue/tie the other end of the floss onto the shutter lever, and glue the timer to the camera in a position so that when the timer unwinds, it pulls the floss, which pulls the lever, which takes the picture. To change the delay time, simple wind the timer less or more. The general idea, once again, is that when the timer winds down, it wraps the floss around its shaft. The floss then pulls the shutter lever, which takes the picture. You must get the timer to start when the rocket is launched, so take a small piece of plastic and tie another piece of floss to it. Jam the gears of the timer with the plastic, and set the rocket on your launcher. Tie the free end of the floss to your launcher, making the floss line taught. Without any film, test the jamming system by winding the timer, jamming it and then pulling the jam out of the gears, this should start the timer, and after a delay, take a picture. It seems complicated, but it can be completed in about an hour. |
