Agreed. However, which would you consider more reliable? Wireless brakes and shifting, or wired brakes and shifting? Wireless is much less reliable because it's susceptible to interference from outside sources, mutual interference from other wireless devices on the bicycle or nearby bicycles, and for low power devices, limited range. I can see wireless control for non-critical devices such as lighting, media player, navigation, coffee warmer, bicycle computer, and perhaps data collection. I would not use wireless for brakes, shifting gears, or any other electrical device that might produce a crash or other accident. 1. https://waic.avsi.aero/about/ 2. https://ntrs.nasa.gov/archive/nasa/c...0070013704.pdf I'm not asking for anything extraordinary, so it seems. If you want reliable wireless, the most common method is to provide both frequency and positional redundancy (also known as diversity reception). For example, if you squeeze the brake levers, instead of a single RF signal path, frequency redundancy would use two (or more) RF frequencies to insure that at least one signal arrives at the brakes and stops the bicycle. Since it is also possible for something to be blocking an RF path, two pairs of antennas are used at each end, each following a different path to arrive at the brakes. In other words, double the cost of the signaling and control equipment. It's not a huge increase in cost, but are you willing to pay the price? Fly by wire, or rather fly by wireless, offers no feedback to the bicycle rider. When one applies the brakes or shift gears, there is some mechanical feedback provided to the rider to indicate that braking and shifting were successful. Without this feedback, the rider could easily make an error in judgment based on the assumption that the braking or shifting was successful. It is technically possible to provide some form of tactile feedback using "force feedback". Some computah joysticks include some form of force feedback to enhance realism. At some point, trying to recreate the "feel" of a mechanical braking or shifting system would become sufficiently complex that simply switching to CVT (continuously variable transmission) and computerized speed control might be easier. Or, one could model both the front and rear derailleur system so that the chain is positioned by a servo motor and pre-calculated to always move in an optimum manner (fastest shift) and land in the optimum position. Do you want a system that always shifts and stops perfectly every time? Replacing cables with wireless control and electrical activation is not going to make all the aforementioned happen overnight. However, it will provide a path where someone is going to try and sell it. My guess is that it will hailed as a great innovation in the name of safety, and then fail miserably when the product liability lawsuits arrive after an early adopter dies because he believed they are expected to save him from his own stupidity. In my never humble opinion, wireless control should be used for accessories, not brakes and shifting. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

That's pretty interesting. I haven't been up Everest, but I've been in the Arctic Cicle and environs, and I've raced across the Southern Ocean in winter several times, and I know there's cold and cooooooold. I found that just a little lower down Alaska even a pair of padded Carhartt overalls were too hot of me to run in. A key idea in such dangerous cold climes is that people kill themselves by doing something stupid. One of these stupid things one is warned about is to permit yourself to perspire and to let perspiration freeze in clothes on you. The built in heaters are usually controlled by a smartphone app via BT: "Mobile Warming" https://www.youtube.com/watch?v=IOKlFJLN2dc Yet another candidate for distracted bicycle riding. Another dumb idea. I can't read the screen of my iPhone outside. That's why it speaks my heart rate and other critical data. I can just hear Nanny's voice saying, "You're overheating now. Stop within twenty yards and take all your clothes off." (Reminds me of the satisfaction I felt long ago when I bought a Volvo estate to take my child to school, and the first thing I did was rip the throat of the Swedish harpy telling me to belt up, not to switch the DRL off, not to exceed 70mph, etc, etc, a lot more I never heard because she had no voice left. Eventually I turned it into a good car by breathing on the suspension and fitting a Chevy V8 which, ironically, was more economical than its sluggish PRV V6.) I remember a movie where this city detective from some warm place goes up North to solve a case, and as he and his guide are about to go bush, the guide grabs his battery powered socks and throws them away, saying, "What will you do when the battery gives out?" Tom Berenger and Denzel Washington? Slow Johnny will look it up of us on IMDB.com. Ande Jute Danger, danger! |

Name something you bought for $20 in 1973 you still own, let alone enjoy. The main inconvenience of tattoos, I've been told, is the pain. My wife has a fascination with them and often asks people about theirs. The most frequent answer to her "Did it hurt?" is "YES!" Some then say "It was worth it." (One said "What can I say? I was stupid.") But whether you like having it or not is not the point. My point was, you probably went though the pain for aesthetic purposes. As to what I own from that era: How about my K&E Deci-Lon slide rule? (Sorry, I don't recall its 1966 price.) In my desk drawer six inches from my knee. A functional tool, as well as a thing of geeky beauty! ;-) I'm also looking at a nice German air rifle, bought used in about '73. It may soon have an appointment with the squirrel I see trying to get to the bird feeder. One of my earliest vinyl record purchases is still here and brought out occasionally. _Medieval Roots_ by New York Pro Musica. Still beautiful and exotic. Other purely aesthetic objects from 1973? I can't think of one right now - probably because my tastes have changed. That's why I don't get tattoos. -- - Frank Krygowski |
