Engine Hacks: The Kawaskai Voyager… V-12?

August 31, 2011 by Jeremy Cook 19 Comments

Although a V-12 engine is always nice, cramming one into a motorcycle definitely qualifies as an engine hack! [Allen Millyard], wasn’t satisfied with the standard number of cylinders (6!) on his already gigantic Kawasaki KZ1300. Like any reasonable person, he decided to graft two of their powerplants together!

In true engine hacker form, inspiration struck at a classic bikes show when someone said “Suppose you’re going to make a V-12 next, then?” [Allen] replied that it would be impossible, but after this conversation, he reportedly had to build one. By the time the show ended he’d figured out how to do it. Lots of work and two six-cylinder engines later, [Allen] had proven this task to be possible.

Although this may seem like a very extreme motorcycle engine hack, [Allen] has done quite a few motorcycle engine mods, making v-twins out of a pair of single-cylinder engines and a V-eight from two four-cylinder engines. Check out the video of his latest beast after the break! Continue reading “Engine Hacks: The Kawaskai Voyager… V-12?” →

The “AlarmTock”, A Chumby Hacker Board Alarm Clock

August 28, 2011 by Jeremy Cook 6 Comments

[Thomas] wrote in to tell us about his latest project, the “AlarmTock”. Like many hacks, this was inspired by some outdated hardware, a radio alarm clock from 1992.

After finally getting fed up with his old alarm clock, [Thomas’] wife purchased him a new one for around $10 from a local retail store. Although most likely an improvement, [Thomas] wondered why after so many years he still had to listen to either an annoying “beep” sound or whatever song the DJ on the radio decided to play.

In true hacker form, he decided to do something about it. [Thomas] crammed a [Chumby Hacker Board], which has much of the same hardware as the [Chumby One] device, into his clock radio. RSS-driven text-to-speech was used to tell him exactly what he wanted to know every morning. A sample .wav file is provided as well as the python script used to execute his morning wakeup routine. For another fun hack from [Thomas] check out his Google treadmill hack here!

A Design Contest With High Odds Of Winning!

August 25, 2011 by Jeremy Cook 13 Comments

[John] wrote in to tell us about this contest hosted by Avnet. All one has to do is upload a video of their design to Avnet’s Youtube page. There are four categories to choose from including: Solar, Communications, Transportation, and Entertainment. Four contestants can win an iPad2.

The only catch, if you can call it that, is that one would have to use at least one component from their “more than five million SKUs available.” The thing that makes this contest more interesting than it usually would be is that there appears to be no contest entries as of August 24th. Official rules can be found on their site here.

The contest runs through the end of August, so there isn’t a lot of time to get a design together. However, it’s possible that you have something already built that fits into their product catalog. Make a 30-90 second video of it in action and you’ve got a (very good apparently) chance of winning an iPad2! Check out the contest video after the break.

High Voltage Hacks: All About Electroluminescence

August 25, 2011 by Jeremy Cook 11 Comments

Although many might not know it, electroluminescent materials use high voltage, and thus qualify for our featured topic. Many may assume that these sheets work in the same way as LED lights, using low-voltage DC power. This, however, is not the case, as they need around 100 volts of AC current to allow them to light up.

For a battery-powered solution, this means converting the battery’s DC power to AC. Adafruit has a good tutorial about working with EL wire and powering it up using a portable inverter. One should obviously be careful to properly insulate any clothing using this material as being shocked is generally not fun.

The video after the break is pretty long, but is well produced and will give you a good background of EL use. If you don’t have 30 minutes to dedicate to this, be sure to at least skip to 2:43 to see one of the coolest EL shirts we’ve seen.

The Scariest Hacks From Black Hat And Defcon

August 24, 2011 by Jeremy Cook 12 Comments

Although [HAD] is generally all about legal hacking, this list of demonstrated hacks could be used for the dark side as well. Hopefully by demonstrating hacks like this, most people can be more aware of how they use their information. Computer security experts also have a chance to hone their skills and see where potential vulnerabilities lie.

Some of the highlights from this article include hacking a Siemens S7 PLC, which can be used for factory automation, a “hacker drone” that we’ve featured before, and a method to deduce someone’s social security number from personal photos on social networking sites. Also scary is a method to shut down certain personal insulin pumps. Although serious in itself, one would hope that other life preserving devices would be adequately protected against intrusion.

One hack that seems like it could have interesting uses in the legal-hacking world is the idea of VoIP botnet control. Although “botnet control” obviously implies illegal use, controlling a computer with voice or touchtones can and does have many legal uses.

“Extrem Konsolen Modding”

August 24, 2011 by Jeremy Cook 27 Comments

Not to be outdone by their North American counterparts, these German-speaking hackers have come up with a truly unique console mod. Although modding one system may be OK for most, the builders of this console decided to combine three systems into one clear plastic box. A stripped down Xbox360, Playstation3, and Nintendo Wii were all put together to form this “Extrem” system.

The build style should be very appealing to those interested in video game hardware. Combining the look of a tower PC with a clear plastic allows one to see all components in action. Since the box is lit up with electroluminescent lighting, one is able to show off this system in the day or at night. Continue reading ““Extrem Konsolen Modding”” →

A Stackable Motor Driver Shield For The Arduino

August 17, 2011 by Jeremy Cook 30 Comments

The Arduino has been used for many purposes, and “shields” are available to make many common tasks easier. However, [Nick] wanted a stackable motor driver shield, so he build one himself!. There are many motor driver shields available for the Arduino, however, there aren’t any that allow one to drive as many motors as were needed for his project, and none that were stackable.

[Nick] had no experience designing and fabricating a custom board, but decided to try his hand at it anyway. Armed with a free version of [Eagle] PCB design software, he designed the board that he needed then sent it to [Seeed] to be manufactured. According to his article, a quantity of 10 Arduino-sized boards can be purchased for the price of $25. At that price point, some hobbyists may want to consider this option rather than manually creating their own circuit.

According to [Nick], he was able to manufacture his first board with no errors on his first run! Not bad for his first try at something like this.
