This is the fourth generation of my camera mount. All four were built using a piece of dense foam glued to a plexiglass base. The foam provided some cushioning and the base is attached to the handlebar using the mount from an old headlight. That mount was glued (using Goop) to the bottom of the base. In the first generation, I mounted my camera to the base with velcro straps that were glued to the camera and ran under the base. That worked well on a camera that was designed to be held horizontally with its LCD dsiplay on top. See: http://www.cs.unca.edu/~boyd/touring/cameramount/agfa1280.jpg. I used that setup for two years and about 10,000 mile of touring. That camera had a lens that was built into the body, did not extend, and had a threaded filter mount. The second generation used a conventional digital camera which mounted vertically, so the velcro strap mount could not hold the camera in place. That camera, unlike the one I had used earlier, has a lens that extended when the camera was turned on and no provision for a filter mount. I found a rigid plumbing adapter that would slip over the place where the lens extended from the camera and hold a filter. This protected the lens and provided a way to hold the camera on the mount. I used bent coat hanger wire to attach the base to the plumbing adapter. I used another piece of coat hanger wire to hold the camera in place from the rear. See: http://www.cs.unca.edu/~boyd/touring/cameramount/casiob.jpg. This setup did one, 4000 mile, tour in Europe before it was stolden from my handlebar bar on the return flight from Europe. For my next years tour in Europe, I built another, similar, plumbing fixture based mount using a flexible plumbing adapter instead of the rigid fixture. The flexible adapter made the mount easier to repair and held the camera more securely. I also upgraded the handle bar mount using a Cateye light mount with a quick release. See: http://www.cs.unca.edu/~boyd/touring/cameramount/10280009.jpg for a bottom view of the new mount. The disadvantage of that setup was that the camera was relatively heavy and the LCD display could not be used while I was riding. I replaced it with a smaller camera which has a display I can use while riding. See: http://www.cs.unca.edu/~boyd/camera/cmtourer.jpg. The new mount uses the same base as the previous mount. I just had to adapt my mount design to the camera. Since this camera has an LCD that can be rotated and swiveled up and away from the body. I have used the area where the the LCD rests against the body for the back part of my mount. My first attempt (http://www.cs.unca.edu/~boyd/touring/cameramount/10280003.jpg) worked OK, but the LCD display would rotate down over bumps and the camera was not held very securely. I fixed both problems by making - from an asprin box, another small piece of plastic, and duct tape - a piece which fits into the back of the camera, holds the LCD up and makes the mount very secure. See: http://www.cs.unca.edu/~boyd/camera/cmrear_left.jpg. I've used that setup for three thousand miles and it works very well! Recently, I added a second kind of mounting adapter to my camera mount. This makes it possible to mount my new Canon S1IS camera if I remove the coat hanger wires from the mount. Since the wires are attached with Goop, it isn't difficult to remove them. I sucessfully used this mount with my S1, but decided that, for use on a handlebar, the S1 had no advantage over the Pentax 33L. Since the S1 weighs twice (!) as much as the 33L, I glued the coathanger wires back to the base . The mount for the S1 use Tamrac camera quick releases that are part of Tamrac's camera strap system. I also made a, flexible plumbing adapter based, lens protector/filter holder for the S1. I carried both the S1 and the 33L on my last tour because the S1, which has a 10X zoom and Image Stabilization, is a better 'off handlebar' camera than the 33L. If I lose or have problens with the 33L while touring, I'll be able to mount the S1 in its place. You can see the quick release connectors in the cmtourer.jpg and cmrear_left images. Here is an image of the Tamrac straps on the S1: http://www.cs.unca.edu/~boyd/camera/cmS1straps.jpg. As you can see, those straps could be used to mount any of the new, mini SLR style, digital cameras to my handlebar camera mount. Using a handlebar mounted digital camera has made a huge difference in both the quality and quantity of images I take while touring. See http://www.cs.unca.edu/~boyd/bicycling.html for my touring web pages and look at the difference between the reports for my first three long tours, without a handlebar mounted digital camera, and the reports since '99 when I started using one. Both my cameras and my skill at using them have improved a lot since '99, but even the '99 web pages show the great improvement made possible by being able to take pictures while riding.
