Dynamo Theft in San Francisco

wrote: oh Lieb you are such a wet resistor Ohm is where the heart is. dyno theft is one of Cal's Big Problems I know. Everyone is into alternative energy in California. That causes an increase in dynamo, generator, alternator, and turbine thefts. You'll probably find the missing dynamo hub perched on top of someones house acting as a wind charger for a cell phone. and a good reason for avoiding owning a D-hub. Maybe. The trend in business is for everyone to pay for everything on a monthly basis, turning a purchase decision into a "lifestyle" decision. No need to own anything if you can rent it. Instead of owning a dynamo hub, you are expected to purchase throw away batteries on a continuous basis. Over the life of your bicycle, that's far more profitable for the energy conspirators than if you purchased a dynamo hub. Try not to let it bother you. see D-hubs around S.Cruz ? Yes, but only on visitors and tourists bicycles. Most of the local hackers (except me) have modified their lights to run on rechargeable LiIon instead of throw away AA or AAA cells. I started one that uses a cell phone battery and external charger, but haven't had time to package and finish it. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Not sure whether you're actually interested in the facts, but Frank's been lying about this whole thing for a decade or more. His original claim was that I was selling MR16 based lighting systems, which was untrue (in the 1980's I sold some H3 and LV504 based lighting systems with sealed lead-acid batteries, but haven't done that in 25 years). When he wore out that lie he switched to his newest one about the commissions. You have to understand that Frank is a pathological liar and that he's obsessed with me. Keep that in mind when reading any of his posts. The best option would be to filter him out completely as many of us in r.b.t. do. While I won't bother to search years back in the archives, but I know that back when you were slamming all dynamo systems (um... back before you put them on your family's bikes), you were saying 20 Watt halogen systems powered by big batteries were absolutely necessary, and that you used to sell such systems (but that people should build their own from your 20 pages of "easy" instructions). I probably referred to that. It's possible you attempted to sell something other than MR (i.e. overhead projector) lamps, even though you spent all your time praising those overhead projector lamps. Regarding your commissions, that was a recent discovery of mine, just a month or two ago. I learned of it from the tag line at the bottom of some of your web pages. That was also where you described yourself as a "guerrilla marketer," and bragged about spamming - er, "engaging all segments of the bicycling community in the promotion of our products..." Ah, here's the text: "About Nordic Bicycle Products "Nordic Bicycle Products is a manufacturers rep company for bicycle components and accessories. Many of the products we represent are designed and manufactured by smaller companies that cannot afford to sell through distribution because of the high costs associated with companies like QBP and J&B, or because the market for their products is so specialized that a distributor cannot provide the necessary marketing support. [i.e. Chinese flashlight makers - FK] "We attend bicycle industry trade shows throughout the world seeking out products that we believe have great potential in the U.S. but that are not compatible with the traditional distribution model. "We believe in guerilla marketing. We engage with the all segments of the bicycling community in the promotion of our products. ... " .... and so on. And the commission bit? Here's that text: "If you found this site useful and were going to order from one of these merchants anyway, then it would be greatly appreciated if you use these links to enter the merchant's site.... The above links are affiliates and I receive 3% compensation from these companies on all orders." (I can give the links to the above to prove I'm not a "pathological liar," but I really don't want to drive any naive customers your way.) So you haven't been getting many commissions lately, Steven? I can understand why you're getting especially testy towards me! No, I'm not obsessed with you personally. But when someone posts nonsense, I do want to see it called out as nonsense. You're just such a rich source of material that deserves proper labeling. - Frank Krygowski |

There's no more need to throw away batteries for lights than there is to throw away batteries for cell phones or digital cameras. http://www.eneloop.info/eneloop-products/eneloop-batteries.html AA Eneloop batteries are rated at about 2000 ma-hrs. It takes two batteries to run a typical LED headlight at 2.4VDC. That's about 4.8 watt-hrs. Sanyo recommends NOT using a fast charger. The standard "overnight" charger takes 3.5 hrs to charge a pair of batteries or 7 hrs to do 4 batteries. The quick charger takes 2 hrs for a pair or 4 hours for 4 batteries. http://www.eneloop.info/eneloop-products/chargers.html LiIon cell phone batteries have a higher power density (in both weight and volume). The bigger smartphone "extended" batteries are rated at 3800 to 5500 ma-hrs at 3.7VDC. That's about 18.5 watt-hrs. Fast chargers take about 30 mins to charge one of these. Advanced batteries are much faster: http://www.extremetech.com/extreme/134635-scientists-develop-lithium-ion-battery-that-charges-120-times-faster-than-normal There is one area where Eneloop batteries are superior. They're allegedly good for 1800 charge cycles, while the commodity LiIon might last about 600 charge cycles. I selected a LiIon cell phone battery mostly because of the form factor and the size. I wanted something cheap, light, small, aerodynamic, commonly available, and easily replaceable. LiIon is much easier to deal with than 18650 cylindrical cells, with their flaky battery contacts, springs, and bulky form factor. The plan is to build something very thin, that could be mounted horizontally on the handlebars for riding, used as a normal flashlight, or turned 90 degrees to clip onto a hat, jacket, or back pocket. In other words, a universal light. Rant: Are you familiar with the term "fixation" in industrial design? It's the tendency for designers to visualize a new product with the same form factor as the old design. In this case, you're thinking of a bicycle headlight in terms of a flashlight with it's cylindrical cells. Methinks such a light neither fits well, or works well on the handlebars of a bicycle: http://802.11junk.com/jeffl/pics/bicycles/slides/bicycle-flashlight.html Forget that there ever was such a device as a flashlight or automobile headlight, and try to visualize a lighting device that looks like it belongs on a handlebar.

Yet most Li-Ion laptop battery packs are composed of cylindrical cells in a flat enclosure. The cylindrical shape makes sense in terms of form following function. An ideal light has a symmetrical round beam with round optics. It's more practical to manufacture a mount for round handlebars and a round light body. There are many lights that run on one or two 18650 cells. |

Hopefully you're ware that I'm not getting any commission from anything from Costco, or dx.com, and rarely get anything from Amazon anymore since most items on Amazon now come from third-party sellers that are not eligible for commissions. The Amazon commissions have been enough to partially offset the cost of hosting the informational sites, but that's it. I haven't gotten an Amazon commission in more than a year.

Jeff Liebermann copper from Burklee ? ride for sport, ride commute at night or dusk/dawn, ride to MB ? and today is Ray Loewy's day ! for a trip down Baja whaling, stocked Energizer rechargeable 1.5V with Energizer recharger and got ZERO results... worthless...abt $40 into the can. same for the SF Li outfit. nada. for the online kayak bilge pump rig of 6 years ago. but a SLA Curt trailer batt a 1250Ah/5 amps looks like a go....maybe drain the cockpit in 5 min max. BTW 6 years ago talk abt lighting here did not arouse imterest, wheels/bearings mostly. fewer commuters...more TdF sport. |

Just realize that he made up the story about commissions because he's unable to counter anything I posted with referenced facts or even simple logic. I have never posted any false or misleading information. What I have posted is information that explains things that run counter to what Frank does himself. He has always operated on the principle that everyone should do everything that he does and believe exactly as he does. |

Clearly the thief did not realize how valuable it is. That photo was taken on November 1, 2013. The fork is probably gone by now. |
