Public Transportation Notifier

April 12, 2010 by Mike Szczys 29 Comments

[Knuckles904] was tired of waiting for the bus. His town had installed GPS units on the buses so that riders could track their locations via the Internet so he knew there should be a way to avoid the wait while also never missing the bus. He developed a sketch for an Arduino to check the bus location and notify him when it was on its way.

This method saves him from leaving his computer running. It parses the text data from the public transportation website and updates both an LED display, as well as a Twitter feed. Now he can monitor several different bus lines via the hardware at home, or though a cell phone if he’s on the go.

Third-person Vehicle

April 6, 2010 by Jakob Griffith 27 Comments

Here is something we didn’t expect (NSFW). The machinima crew behind RedVsBlue, Rooster Teeth, actually did a hack!

The idea is simple enough, how could you experience driving a vehicle like in a video game – aka, third-person. With some steel bar, Canon 5D camera, and a 15inch monitor inside of a blacked out cab, they accomplished just that.

What surprised us the most, is the great difficulty and difference there is between the video game vehicle and the real life one. But all of us here at HAD know why; they need to replace the steering wheel with a joystick. While they’re at it they can make it wireless and remote-controlled. Finally a HUD would be easy enough to program (might we suggest processing). Oh dear lord, is the world ready for this!?

Nixie Tachometer

A Nixie tachometer is new to us. We’ve seen tons of various displays, but not a tachometer. After having extensive annoyances with the factory ignition timing system in his totally awesome Holden Gemini, [Brett] installed a MegaJolt electronic ignition system. To top things off and add that extra bit of flair, he built a nixie tachometer to sit on his dash. Not only does it have the numeric read out, you can see a nixie “bar graph” on top as well. Skip to about 2:30 if you want to go right to the action. You can download the Arduino code from the forum post.

Fan-powered Skateboard

March 25, 2010 by Mike Szczys 37 Comments

[Chris Neal] is starting his hacking career young. He built this fan-powered skateboard for his fourth grade ‘Invention Convention’. The ideas were his own but he had some help with the construction from his uncle who owns a repair garage. On the back of the board there’s a motorcycle battery that powers the fan. We’re not sure where that fan came from, but apparently it can push a rider at about 3-5 MPH. [Chris] scored a free MacBook pro from this hack after being featured on the Ellen DeGeneres Show.

For some reason this sparks the memory of the drill powered minibike.

$500 Craigslist Car Competes Against $400,000 Race Car…

…and wins. Well, 3rd in class, but still surprisingly well for such a cheap entry. This is truly a show that with enough elbow grease and headlight fluid anything can be accomplished money just makes it a ton easier.

Everything from the roll cage to the 5 minute gas tank fix was fabricated by [Bill Caswell]. Well — fabricated is a rough term for duct tape at that point, but this is still an awe-inspiring and truly motivational story for any hacker and car enthusiast alike.

Balancing Skateboard/segway

[XenonJon] got a lot of attention for a skateboard/segway style balancing platform he took to the Makerfaire in Newcastle. He decided to try to build it the cheapest and easiest possible way in an attempt to help others build their own. The build is documented very well, however you have to email him to request the code for the Arduino. Maybe after enough requests, he’ll just pop it online. We thought this looked familiar, so we searched the archive and found this very similar setup from back in 2005. Unfortunately, that project page appears to be gone now.

Tim “The Tool Man” Taylor’s Dream Ride

While surfing one of our favorite websites, we came upon this little jewel. We can’t really tell if this is hack-worthy, or just a deathtrap, so to help decide…

Mechanics crawler + 80cc motor – safety concerns = deathtrap

It’s really that final “Brakes? Why would I need to stop?” that puts this project over the edge. Regardless, check out a video after the break. And please, do not try this at home.
