Motorcycle lighting upgrade ensures other drivers know you're there

led-brake-lights

[Pete Mills] recently bought himself a motorcycle, and as people are known to do, they start trying to scare him with gruesome stories of cycling accidents once they hear about his purchase. While he tries to shrug them off as people simply not minding their own business, something must have resonated with him, because he started tinkering with the bike’s taillight in order to ensure he was always seen by other drivers.

He swapped out his motorcycle’s incandescent taillight for a smart LED-based lamp that he constructed using perfboard. Not only does his new brake light feature ultra bright LEDs, but the onboard ATtiny85 rapidly flashes the lights each time he hits the brakes, making his presence impossible to miss. Before everyone starts with the claims of, “Flashing red lights are illegal!”, let’s all take a deep breath and read on.

We’ve seen these sorts of lights on the back of motorcycles for years, though being a careful guy, [Pete] wrote to the state of Michigan in order to ensure that his modifications won’t get him pulled over. He has yet to hear back, but in the meantime, he merely needs to start the bike with the brakes applied to trigger the ATtiny85 to run the lights in “normal mode.”

Bodging up a diesel motorcycle

[Alex] has been working on a diesel motorcycle project for a few months now, and the project is finally bearing fruit. It’s quite an accomplishment for something [Alex] describes as an industrial Chinese engine, a modded Honda Superdream, and a few Royal Enfield parts thrown in for good measure.

[Alex] bought his Honda CB400 from someone who had already done a diesel motor conversion; a 200cc single-cylinder motor provided just enough horsepower to putt around town. [Alex] wanted a bike that could keep up with highway speeds, so he replaced the wimpy 200cc motor with a 406cc diesel engine used for industrial purposes and an amr500 supercharger.

Although we’ve seen a few insane motorcycle builds, most of Hackaday’s bike builds focus on electric or scavenged parts motorcycles. If you’ve got an awesome motorcycle build you’ve been working on, send it in on the tip line.

You can check out the video of [Alex] testing out his new motor with vegetable oil (for him, it’s easier than getting diesel fuel) after the break.

Motorcycle engine hack like having an old F1 between your legs

The difficulty of rolling a 16-cylinder engine into a motorcycle really boggles the mind. But that’s exactly what [Andreas Georgeades] is doing in his garage. It’s two straight-8 engines sandwiched on top of one another with a custom crankcase connecting them. And get this, those custom parts are being milled by hand, using time-tested techniques rather than modern computer assistance.

So, where does the complexity come in? Well first of all you’ve got to solve all of the problems that go along with combining two engines. It sounds like this isn’t a new concept, as older generations of Formula 1 engines used the technique. But we still think it’s the pinnacle of hardcore when it’s an enthusiast undertaking the challenge. Then there’s the issue of weight. The engine is bulky, but needs to balance in the frame. And you still must find a way for the rider to sit on the thing (even the most bow-legged of people won’t be able to get their hips around the thing).

Seems like something out of a Mario Kart game that should have no chance of being roadworthy. But we’re sure [Andreas] is going to prove us wrong.

Suzuki V-Strom current gear indicator

[Iron Jungle] just finished building this gear indicator for his motorcycle. It uses a red 7-segment display to show the rider what gear is currently engaged. This hack is pretty common and makes us wonder why all motorcycles don’t come standard with the feature? But then again, if they did you wouldn’t have a reason to hack them.

The motorcycle does have a gear sensor; apparently it only lacks a way to display this data. The sensor outputs a signal between 0 and 5V which [Iron Jungle] reads using a PICAXE 18M2 microcontroller. Patching into that signal wasn’t hard at all. Once he found the correct wire he simply removed a portion of the insulation and soldered a lead to the conductor. This should stand up to the vibrations encountered in an automotive application like this one. Since the computing power is already there, he also included a DS18B20 to take ambient air temperature readings. Check out the quick demo after the break.

This is not the first time we’ve seen the V-Storm get a custom gear indicator. But if you really want to go all out, perhaps you need to build an interface for your tablet or smart phone. [Read more…]
