Video A Bike Taillight that Goes Beyond Mere Taillighting (Video) 86

Video no longer available.
Meet David. Tim Lord ran into him at the 2014 Maker Faire Bay Area. He didn't have a display, and he wasn't obviously trying to sell anything or promote a Kickstarter campaign. He was just walking around with a panel full of LEDs that he wears as a backpack while riding his bike, which beats the heck out of regular bike taillights, even the blinky flashy ones a lot of us have these days. So good on you, David. This is your three minutes of Slashdot fame -- and please note, people, that you can now fast-forward through any preroll ads longer than 30 seconds, so you won't get bombed with multi-minute ads to watch a three minute Slashdot video.

    As a fan of lights myself, that's pretty darn awesome - great job David.

    Bummer the video didn't have any product demonstrations in low light while on a bike ...
    • It was a bit hard to see in the video... and I think it needs to be a little bit brighter in any case, even in daylight a good bike light is clearly visible.

      Note to cyclists: as a motorist who often drives down poorly lit country roads with lots of bicycle and car traffic, I see many cyclists with poor illumination, namely those poxy blinky LED lights.

        • It might have saved him, if the drunk driver would have spotted him earlier because of it. Besides, good illumination is not about making you safe from any and all accidents, it's about vastly improving your odds in situations that can potentially turn into an accident.

        lucky you. I live in Italy, where usage is low, but authorities have an hardon to increase bike usage. Pity that in their enthusiastic laissez faire attitude they do not enforce any kind of behaviour on cyclists, so in the dark you simply try to avoid dark shapes against a darkish background. Tonight, out of about twenty bikers, 1 (one) had a working light set but he was cycling on the wrong side, the rest were practically invisible, without even reflectors, and two were cycling in the dark side by side. s

          I do expect my investment in an onboard camera to pay off, unfortunately, when one of these bumbling fools gets too darn close for comfort. Sorry, but stupidity should pay a price in real life. Why should I get stuck with the bill because I drive carefully and you do not?

          Well you are driving around in a massively dangerous thing that destroys the lives of so many people, that's why you should pay when you hit a person. Because when cars are driven too fast, anything above 30 km/h, they kill people.

          • Well, the thing is, roads do not ban bikes from them. And bikes are obliged to follow much of the same laws as cars, at the least for driving. Not safety.

            Lol ! you are the perfect example. in what universe one race can flout all existing laws, an as a consequence the other race is stuck with more laws, and it had many more to comply to begin with?
            where I live, there are bike only lanes physically separate from car lanes. I am more likely to spot Godzilla reading a sport magazine at my cocktail bar than a cyclist using them.

      • So yes - those blinky ones are great for spotting in periphery vision, but terrible for tracking the movement of the cyclist. You really MUST have a solid rear light if cycling in the dark. A blinky one as well is good, but the solid makes all the difference.

      I would worry that you'd do something to distract or offend a driver behind you with this thing and get hit. I'm not convinced that it's a safety win. It's definitely a fun hack, though.

      • I agree totally. It might get one seen, but it is distracting to the point it probably would be very dangerous for the wearer.

    Got two Monkey Lights on my rear wheel that light up pretty good as I commute on Tokyo's streets, no need for any backpack or such.

      Fixed that for you. For us non-racers, a few extra pounds isn't a big deal, especially when you're already carrying a backpack with a laptop or books or groceries or whatever.

          Define "Long Distance"?

          Heck, I always have a backpack on when I ride. It has spare tubes, tools, extra water, phone, etc. When I bike to work, it also has a soda, office keys, and some clothes for when I get to work.

          The ride to work is 15 miles. I wouldn't call that "long distance." But I've done 60 mile rides with the backpack and no problems. I'm doing a 100 mile ride in a few weeks and I'll definitely have the backpack.

          C'mon--toughen up! :^D

          Do people actually ride bicycles long distances with a backpacks on? Haven't y'all heard of panniers?

        • No every ounce counts when you want to get somewhere fast with minimum effort. If you want long distance riding you should take a look at what some of the professional tourers do. Some of the features of one bike I saw on display:

          - Steel alloy frame won't crack at the first sign of a jolt, and easy to repair with a welder.
          - Large tyres with thick rubber to ride over glass, rocks and other nasties.
          - Internal gear hubs (hub is heavier than both of my racing wheels + tires combined).
          - HID headlamps and large l

        • Dunno 'bout you, but I'm on a bike to get somewhere. Getting there safely -- which paying some costs in weight for better lighting, thicker rims, and a frame built of high-grade steel (with its far safer failure modes than aluminum or carbon fiber) supports -- is more important than a few extra seconds that will probably be spent waiting at a stop light anyhow (and yes, I do put my foot down at stop lights, because my priority is safety, not shaving off seconds). Sure, I'm carrying a little more weight and

    • Seems a bit big and bulky for a bicycle rider, where every ounce counts.

      It's a prototype. That design lends itself to mas production. You could have that produced as a 1/4" thick flexible mat that weighed less than a few ounces and could be priced under $10. It would be pretty easy actually.

      Not just drunk drivers. Any driver can be easily distracted. A driver who is distracted from other things going on around them is also very dangerous to you, even if you're the source of their distraction. The goal should be maximum visibility without distraction, not maximum visibility caused by maximum distraction. Pong, smiley faces, and the occasional word? Yeah, that's meant to be distracting.

      • Oh, come on. Only if it's one person standing out from the crowd. If everybody had multicolored flashing lights as tail lights, it wouldn't be distracting at all.

  • check out what these croatian guys are doing with integrated bicycle technology: their Visiobike is perhaps alittle ahead of its time, but i'd get one. see their indiegogo campaign at igg.me/at/visiobike looks like they need our support.
  • I'm pretty sure the legality of this in use on the road using animations or any colour other than red is questionable at best.

    You could get an old laptop display, or even a tablet, be it Android or iProduct and beat this thing in every way. But you can't see a tablet well in the sunlight? I think it's obvious from this video you can't see that thing in the daylight either.

    I'm not knocking the guys ability or talents, but he invented the light display AFTER the Jumbotron came out.

    I'm a cyclist, I think things like Monkey lights are incredibly awesome, I think the new inner rim lights are great, but this isn't on point.

    It "beats the heck" out of them? Well, thanks for that devastatingly insightful exposé of the limitations of existing bike lights.

    Heaven forfend that my blinking red light should bore a driver.

  • Flashing lights undoubtedly draw the attention of people behind them on the road.

    The problem is they do their job too well and become mesmerizing, drawing attention away from actually driving. People become so focused on the lights they don't realise that they're driving dangerously close to the bike, they start to slowly edge onto the wrong side of the road or they simply miss hazards up ahead.

    Lots of drivers dislike even simple blinking red lights because of this. This 'jumbotron' will actually make

It would be a lot more practical (not to mention more convenient and lighter) to sew these into the covering flap of a messenger bag or similar (like he had), using easily-obtainable RGB LEDs on flexible PCB strips (like he was using) that are already sealed and watertight. The only difficulty would be sealing the connecting points, but that wouldn't be too much of an issue, and if you're going whole hog and making from the SMT parts up (instead of repurposing
