I beg to differ. The "short range transmitter" will need to operate on all the cellular bands in order to work with any service provider and technology. It might look like the abomination in the above URLs. You could probably substitute a fast frequency hopper and large broadband antenna (discone). However, the modulator and SDR (software defined radio) needed to clobber any an all cell phones, no matter what band, frequency, and modulation scheme is being used, is going to a design challenge. Of course, accidentally jamming cell phones used by public safety vehicles will be a problem because there's no way to distinguish distracted motorists talking on cell phones from legitimate emergency traffic. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I don't remember how the last year that the dimmer switch was on the floor but I do remember the first car I saw with the light switch on the steering column and how strange I thought it was... some sort of strange European scheme I remember thinking.

When you met another car it automatically dipped the lights... and also dipped the lights every time your light lit up a big roadside sign :-) -- cheers, John B. |

I guess you know that cell phone jammers are illegal. https://www.fcc.gov/general/jammer-enforcement I have given it careful thought. Think some more. But when traveling as a passenger I increasingly see drivers drifting over into other lanes. They are irresponsible idiots who are a danger to everyone. It won't work the way you expect. Jamming a cell phone will cause the phone to disconnect unexpectedly. The driver will wonder what happened to their call in progress and begin finger poking at the screen trying to re-establish the call. That's not a great idea while moving. Prior to your jammer being turned on, the driver was minimally distracted. After jamming, the driver became actively engaged in operating the phone and has become seriously distracted. You may think that full time jamming only prevents initiating or receiving phone calls. That might be true if you were moving at the same speed as the traffic. However, there will be many cars passing you on your bicycle, in both directions, some of which might be engaged in a legal hands free phone conversation. Your jammer will disconnect their call in progress, cause them to finger poke at the screen, and probably cause an accident while they are distracted. Also, there are now so a substantial number of cellular bands in use (and growing with every FCC auction). Unless you plan to carry a rather large box on your bicycle, it is unlikely that you can efficiently jam all of them. At best, a simple jammer will take out all the customers of one particular vendor, leaving the other vendors bands unaffected. http://www.gasiajammer.com/sale-8508330-new-all-in-one-16-channels-high-power-desktop-signal-jammer-70-meters-sheilding-range.html https://www.youtube.com/watch?v=gMOpxrs53YQ -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 Any phone use whether hands free or not is distracted driver. i.e. dangerous driver If not every phone is knocked out, no problemo. They may figure out that their phone only misbehaves when driving. :-) Fred My guess is that the immediate result of someone's phone stopping would be an immediate flurry of shaking the phone and feverously pushing buttons to get the damned thing to work. Rather than cause the driver to pay more attention to driving I suspect that it would have exactly the opposite effect and he/she/it's attention would be wholly on the phone. In fact we had a crash a few years ago, for a somewhat similar reason, where a pickup drove straight into the rear of two cyclists and killed them both. The pickup driver said that he had dropped his phone and was bending down to pick it up and didn't see the bicycles. For any that are interested the driver is now serving a prison term for causing a highway death. -- cheers, John B. |

I wonder whether he may not have been correct? Does that decode into; I wonder whether he may have been incorrect? Something else to wonder about is why public safety, transportation services, ham radio, CB, and other 2way radio users have been driving around talking on their radios for about a century without much of a problem. I didn't see any mention of distracted driving until the advent of cell phones (and LCD touch screens). So, what's the difference between cell phones and 2way radio? Cell phones are full duplex while mobile radios are half duplex. Full duplex means the one talk and hear at the same time. Half duplex means the radio can transmit or receive but not both at the same time. The human brain can multitask two tasks at the same time with minimal confusion (not zero confusion). It can deal with operating the vehicle while listening to the radio. Or, it can deal with operating the vehicle while talking on the radio. However, it cannot deal with operating the vehicle while talking and listening at the same time. Three tasks are too much to handle. To fix the problem, switch the cell phone from full duplex to half duplex and require the driver to depress a PTT (push to talk) switch while talking. This has the added bonus of giving the driver a rest while he listens to whatever the other party is saying, much like the common AM/FM/CD/USB player. In effect, make the car kit cell phone operate like a 2way radio and it might reduce distracted driving accidents. It won't reduce them to zero, but it will be a big help. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I didn't see any mention of distracted driving until the advent of cell phones (and LCD touch screens). So, what's the difference between cell phones and 2way radio? Probably because you don't need to look at a radio microphone to use it. Airplane drivers wear a headset and microphone and jabber a lot without crashing.

Siri can do that as well https://www.dummies.com/consumer-ele...r-texts-aloud/ (and with the appropriate in-car integration, without needing to touch the home button). I have sat in a car as a passenger when the driver was texted by his wife and sent an answer via Siri. Needed a few repetitions to get the right text but still simpler than ringing her to pass the estimated arrival time. |
