enzed_viffer Posted February 28, 2006 Share Posted February 28, 2006 (edited) Tired with people tailgating me, and having to fan the brake lever to warn them I was slowing down, I looked at the available brake-light modulators available. I really liked Signal Dynamics one http://www.signaldynamics.com/products/Modules/xp.asp and the Kisan ones also looked OK http://www.kisantech.com/index.php?cat_id=3 Then I talked to my TechnoNerd son (#2), pointed him at the Signal Dynamics site, and asked what he could do. He thought for a few milliseconds, and said, "Yup. I can do that." Eventually ( he was very busy with important projects like Quake, GT4, and suchlike), he ran a virtual prototype on the PC, got it to work, then bought the various doodads required, built a 'bread board' prtotype, and got that to work too. Then, after much hassling, and some help from me with drilling and stuff, the doodads were assembled into a Thing. border='0' alt='user posted image' /> mod1.jpg I then cut the wires (green, yellow and red) to the brakelights (I knew which ones they were, because I'd already cut the earth/ground and taillight wires to hook my R/R fan into them), and put some bullet connectors on each end of everything, and hooked it up. Yup, miracle of miracles, that worked too, so after some thought, I cut a plate of thin, galvanised steel (No Dad! You can't use aluminiumininum - it'll corrode!"), loosened off the screws holding the taillight assembly in place, and fastened the bracket across under the cowl. A strip of 3M fastening stuff (like velcro, but different), and it's all go. border='0' alt='user posted image' /> mod2.jpg So, now when I brake, the brakelights flash 5 times, then stay on as long as I hold the brakes on. It's illegal here apparently, probably because it's a Good Idea and aids safety. The Safety Nazis don't like people doing sensible things, and frown upon people who take it upon themselves to improve safety without Official Approval Or Sanction. We've already got some ideas for improvements, like using a MOSFET transistor instead of the one we did use, which would obviate having to use a substantial heatsink. The first one we tried was too small, and heated up to about 70 C. The one we used was a pentium processor heatsink, which is larger than it needs to be, but it was just lying around, and we couldn't be bothered cutting it. Also, it'd be kewl if the taillights flashed when the brakelights do, in added emphasis. We may also reprogram the micro so that there is a decaying flash rate, rather than steady one, so it starts off flashing fast then slows down. But it's all good, and for ~$22, it's also a cheap aid to safety. And I've got my stories sorted out for when the Safety Nazis object and try to ticket me. Interfering bastids.

nexzzt Posted April 5, 2006 Share Posted April 5, 2006 The Safety Nazis don't like people doing sensible things, and frown upon people who take it upon themselves to improve safety without Official Approval Or Sanction. <{POST_SNAPBACK}> I think it has something to do with being mistaken for an emergency vehicle (yer right, like your gunna mistake a bike for a few tonnes of fire truck). Anyway, I agree with you. Why make thing easy and safe when you can add red tape and bureaucracy and really screw things up.

The only complicated thing is that he used an interface to the PC and an EPROM programmer (or like that there) to program the micro. But maybe if there's a few of these wanting these who can't do the soldering and/or programming, he might be convinced to make them up and send them to you. If that's the case, you could specify what sort of flashy thing you wanted to happen, like 6 flashes then steadily on, or decaying flash rate (faster then slowing down to steady on, or whatever). I've been thinking of getting him to reprogram mine so it flashes with slightly longer pauses. The next model (if there is one) will have a MOSFET transistor, so it doesn't require the big-ass heatsink. Quote Link to comment Share on other sites More sharing options...
AB-Oz Posted April 6, 2006 Share Posted April 6, 2006 I think its groovy and would like one . Pretty good exchange rate from Oz Rahzoos to NZ Kiwicents too right now If the plod stops you then you'll have to explain that it must be a faulty wire, then if they are really zealous and you have to open it up you say "What the hell is that!!!!???"

He's very, very tiring to live with. He has Aspergers Syndrome (high functioning autism), has an IQ and cognitive abilities in the upper 1st or 2nd percentile of the population, and is always ON. His older brother is similar (they're both intelligent and obsessive) except gregarious, and when all three boys are together, they all talk very fast, and very LOUD, and at the same time (they reckon they talk in full duplex mode). Life has been... um... very interesting... Quote Link to comment Share on other sites More sharing options...
enzed_viffer Posted April 6, 2006 Author Share Posted April 6, 2006 Anyway - I'll get TheDave to draw up the circuit diagram (I suspect he's got it on the computer, as he has a bench-testing program he ran it on before he even put the thing together in 'bread board' mode), and post it here. If anyone wants to make their own, I'll get the programming for the micro from him, and if anyone wants to make their own but can't program the micro, I'll see about supplying just that on its own, and if anyone's interested in a complete assembled unit, I'll get him to price that. Obviously, it won't be as "cobbled together" as this prototype. By the way - the thing is still going great, after 6 weeks' use. I haven't had anyway 'target fixate' on it and rear-end me, so I guess it's doing it's job. Hard to say, as I've only been rear-ended once prior to fitting this, and that was on the VTR.

Guest 767fixer Posted April 6, 2006 Share Posted April 6, 2006 my daughter talks loud too....usually to friends on the phone which has been grafted to her ear due to length of time it sat there. she can't spell I.Q> so i cant give you her percentile ranking. we just had the baby boy .... so hopefully there is a chance for one of my siblings Quote Link to comment Share on other sites More sharing options...

He mentioned that he didn't think it was right "that 50cc scooters don't have to have a Warrant of Fitness, and only just the other day he saw one that had a smashed up rear end and red cellophane for the taillight and that was just wrong and there should be a law change and ..." "Nathan - I don't agree; you're obviously a SafetyNazi! There are far too many laws, rules and regulations already. Just let it go, Dude!" I think Nathan rides his bike (2005 SV650) just because it's economical. Talking to him about bikes is just like talking to someone who doesn't understand what motorcycling is all about...

Guest girardi09 Posted April 6, 2006 Share Posted April 6, 2006 I have a question, I actually have the signal modulator, but am struggling with the wiring since there are two break lights, and twice the wires... any insights as to how to wire this correctly???? I am no dummy :beer: , but I do have a history of making mistakes. I do have a wiring diagram and know which wire is which but just do not have a clue as to how to connect it. Thanks for any advice you give me. Quote Link to comment Share on other sites More sharing options...

I cut the Green/Yellow going to both brake lights and put female bullet connectors on the side coming from the wiring loom, and male bullet connectors on the other cut end. The input on the modulator had a male bullet connector, which went into one of the female plugs. The output on the modulator had a "Y" with a female connector on each end. The male connectors on each brakelights' green/yellow wires plugged into these. One female green/yellow connector is unplugged, but I may yet use both brakelights' wires as inputs, as the modulator consumes a slight amount of power when running, so I'm losing a slight amount by having a one wire input. Does that make sense? If, at any stage I take the modulator out (say, it blows up), I can just unplug it, and plug the brakelight wires back together again.

Guest DMACK Posted April 7, 2006 Share Posted April 7, 2006 I'm right there with you 767fixer. My daughter has made mac & cheese from a box, but it wasn't anything I'd eat. She poured it into the water to boil, then went to talk on the phone for about 40 minutes. It looked like cheese colored flour mush! She has no interest in motorcycles, cars, school, or anything that doesn't involve the phone, myspace or red streaks in her hair. Were working on a boy!

There's a guy I work with who has a 2 hour drive from his house to the client we're both working at - and bitches about it constantly when he owns a Ducati 998 and could do the trip in 40 minutes! I constantly berate him about his lack of riding but he complains that it's really inconvenient to put his motorbike gear on and off. Bloody cafe racers, the lot of 'em! P.S. My first child is a boy and he absolutely loves the bike. Sits on it and goes "rarr! rarr!". So cute! border='0' alt='user posted image' /> He can't walk yet, but already wants to ride!
