Helmet mounted video

The posted video looks clear enough to pick up a license plate of a passing vehicle. Is that the case? I didn't see any in the videos. Dear Joe, License plates didn't show up well in the videos that I reviewed. It depends on how steady the rider's head is, where he's looking, and so on. The plastic wrap rubber-banded over the lens doesn't help. Here's a frame where neither license plate is readable, with the park ranger's sedan doing ~10 mph, the trailer doing ~20 mph, and the bike doing ~15 mph: http://i52.tinypic.com/5oai8.jpg Here's a parked truck whose plate is probably unreadable with the bike doing ~15 mph http://i55.tinypic.com/oarsao.jpg I can just read the black "154" and the light blue "Colorado State Parks" on the tailgate (it helps to know what you're reading), but I can't read whatever's in front of the "UL" on the license plate. I may try a handlebar mount, just to see if it does better. My guess is that it will vibrate badly because of the missing human suspension. For comparison, here's a frame from an ordinary hand-held camera in video mode, showing a license plate on a truck passing the bike: http://i53.tinypic.com/2ng90xs.jpg The Canon PowerShot A570 camera is probably a much better camera, it had no plastic wrap over its lens, and holding it in one hand as I pedaled along put it out on the end of a lot of damping. Cheers, Carl Fogel

A flock of scavenging obstructions, frightened by the bicycle going past on the highway: *http://tinypic.com/r/dgi3hz/7 The other day I spooked a pair of black vultures http://en.wikipedia.org/wiki/Black_Vulture that were trying to open up a bloated and stinky roadkilled squirrel in the parking lane a few doors down from my house near downtown Austin. They'd take a few quick pecks at the thing, then get flustered away by a car or other passerby, then waddle back over and repeat the cycle, over and over again. Chalo

Wheelbuilding obstruction
Mounted a 415-MC under an E250’s hood lip ops with the standard Ford horn or not. AAA results: deer, R. Elk and street grade elk stop to listen, consider, mull or deliberate before running willy nilly across the street lika buncha weed crazed rabbits. Note in specialty horns, a bell horn. http://www.wolo-mfg.com/motorcycle.htm contray to expectation, the 415 is durable. Connections are liquid plastic insulated, the compressor under a H2O2 bottle.

Where's Carl Fogel when you need him? Then we'd have follow-up photos of the obstruction being prodded with a stick. ------------------------------- John Dacey Business Cycles, Miami, Florida Our 28th yearhttp://businesscycles.com ------------------------------- Dear John, Sparing no expense, Fogel Labs has obtained an $18 helmet camera to capture images of obstructions too quick or wary to poke with sticks: http://tinyurl.com/3lqj7sb The sub-$20 camera arrived in about ten days. Some zip ties and holes drilled through a styrofoam hat hold the camera mount in place. Since I ride head-down on the drops, the camera is tipped back at an angle suitable for anti-aircraft fire. Some plastic wrap secured by rubber bands protects the costly lens: http://i55.tinypic.com/2qmddp5.jpg I doubt that the weight or wind drag hold me back very much. To use the camera, you ignore the awful manual, press the power button until a little light comes on, press the mode button until the light begin to blink, shout "Action!", strap the helmet on, and pedal off. It records sound, too, and comes with a charger in case you don't want to tie up a computer's USB port. The included 2gb card wasn't quite big enough to capture an hour-long ride, so a larger 4gb card was purchased. An $18 16gb card then proved irresistible, being the largest that the camera can handle. *** A typical obstruction, browsing by the side of the road: http://tinypic.com/r/sw5xcz/7 A flock of scavenging obstructions, frightened by the bicycle going past on the highway: http://tinypic.com/r/dgi3hz/7 A pair of frisbee-golf obstructions in a 20 mph zone, one dumber than a brick: http://tinypic.com/player.php?v=iegk76&s=7 A mated pair of obstructions, oblivious to traffic and common sense: http://tinypic.com/r/2rwlwg1/7 Cheers, Carl Fogel This frame caught my eye while I looking through a helmet-camera file: http://i52.tinypic.com/xy993.jpg The odd streaks going past the handlebar are just chip-seal pebbles going past at 30 mph, captured when I ducked my head to cough on a downhill and pointed the helmet camera at the whirling spokes: http://tinypic.com/r/hvb1x2/7 Cheers, Carl Fogel
