Scout, The Autonomous Transatlantic Boat

May 2, 2011 by 22 Comments

Sailing a small boat across the Atlantic ocean is quite the daunting task. As many have discovered, it is a journey often fraught with perils, typically ending in failure. A team of four college students decided the best way to get a small boat across the ocean would be to remove the human element from the process, so they set off to build an autonomous craft to take on the task.

Like most projects, this one started as a handful of wild ideas exchanged between friends [Dylan Rodriguez and Max Kramers]. As they thought about it more, they decided that turning [Max’s] sailboat into an autonomous ocean-going craft would be pretty awesome, so they got to work. Recruiting help from their friends [Brendan Prior and Ricky Lyman], the project started to quickly take shape, and Scout was born.

Scout is 8 feet long and consists of foam core covered in carbon fiber. It is filled with various electronic components such as a SPOT tracker, a battery bank that will power the boat for up to 25 hours, and the various servos and motors which will be used to pilot the craft.

It’s a rather ambitious project, though the boat is nearly complete – just in time for their launch, slated for May 29th. We’ll certainly be keeping an eye on this project as the launch date approaches – good luck guys!

Head on over to their Kickstarter page to see a promo video introducing Scout.

HDD Unlocking On The Mitsubishi Multi-Communication System

April 29, 2011 by 15 Comments

It’s a few years old, but [Brian360’s] method of unlocking the hard drive on his Mitsubishi Multi-Communication System is quite interesting. Mitsubishi describes their MMCS as a human-vehicle communication tool. It’s basically an in-dash screen and controls to display navigation maps and play music. [Brian] found that the hard drive for the MMCS in his 2008 Lancer was locked, and could not be cloned and swapped out for a larger drive. Sound familiar to anyone? Hard drive locking has been used in many systems, including the original Xbox, which we’ll get back to in a minute.

The setup seen above was used to grab the hard drive password from the system itself. A custom adapter card was built and plugged in between the hard drive and the MMCS hardware, with test points for each of the data line. [Brian] attached a digital storage oscilloscope, and after a bit of poking around, found a way to trigger the scope when the password was requested. He explains the process of converting the captured data into an ASCII string password.

With that in hand how would you unlock the drive? The favorite tool for this is hdparm, a tool which was used with early Xbox unlocking but which is still in use with other hardware today. Now brian has a disk image backup and the ability to swap out for larger hardware.

Wooden Bike Hopes To Set World Record, Not Catch Fire

April 28, 2011 by 21 Comments

splinterbike

[Michael Thompson] has been hard at work for well over six months building a bicycle made entirely of wood. The project started as a bet between two friends, and has become much more over the last few months. The SplinterBike, as it is being called, has been constructed solely from wooden parts, as well as glue and paint – but not much else.

The bike uses many different woods in its construction, each chosen to fulfill a particular purpose. The axles are made from hardwood ekki, while all of the gears, wheels, and frame parts were constructed from birch plywood. Oiled ironwood was chosen to serve as a replacement for metal bearings wherever moving parts came together due to its durability. Other parts were constructed with random scraps that [Michael] had sitting around in the shop, such as the handlebars which were cut from an old broomstick.

Now that the bike is complete, [Michael] and his friend [James] are gearing up to set a wooden bike land speed world record. It should be doable, as they have calculated that the bike should hit about 31 miles per hour provided [James] can pedal fast enough. A date for the record attempt has yet to be set, but keep an eye out – it’s likely to be an entertaining show.

Be Lazy, And Get Somewhere At The Same Time

April 27, 2011 by 25 Comments

Cruise the beach in comfortable Jamaican style with this motorized hammock. [Stephen Shaffer] and his friends built it for the Red Bull Creation contest which has as its number one requirement, the need to include an Arduino. We’re basically looking at a hammock frame made out of square pipe that has been put on wheels. Watch the video after the break to see the prototyping, construction, and final product. Looks like originally the electric wheelchair base that’s used for propulsion was centered below the hammock. One sharp turn and the rider/operator gets dumped out on the concrete.

The final version includes a couple of wheels that serve as outriggers, keeping the vehicle upright. A PlayStation 2 controller is used for steering and directional control. It’s polled by the Arduino, which then uses servo motors to control the original wheelchair joystick. At least that’s what we were able to figure out by watching the video.

Enhance Your Key Fob Via CAN Bus Hacking

April 26, 2011 by 30 Comments

[Igor] drives a 4th generation Volkswagen Golf, and decided he wanted to play around with the CAN bus for a bit. Knowing that the comfort bus is the most accessible and the safest to toy with, he started poking around to see what he could see (Google translation).

He pulled the trim off one of the rear doors and hooked into the comfort bus with an Arudino and a CAN interface module. He sniffed the bus’ traffic for a bit, then decided he would add some functionality to the car that it was sorely lacking. The car’s windows can all be rolled down by turning the key in any lock for more than a few seconds, however this cannot be done remotely. The functionality can be added via 3rd party modules or through manipulating the car’s programming with some prepackaged software, but [Igor] wanted to give it a go himself.

He programmed the Arduino to listen for longer than normal button presses coming from the remote. Once it detects that he is trying to roll the windows up or down, the Arduino issues the proper window control commands to the bus, and his wish is the car’s command.

It’s a pretty simple process, but then again he has just gotten started. We look forward to seeing what else [Igor] is able to pull off in the future.  In the meantime, continue reading to see a quick video of his handiwork.

If you are interested in seeing what you might be able to do with your own car, check out this CAN  bus sniffer we featured a while back.

IP-based Engine Remote Enable Switch

April 17, 2011 by 28 Comments

remote_enable_switch

[Mariano] owns a late 90’s Jeep Wrangler, and had no idea just how easy it was to steal. Unfortunately for him, the guy who made off with his Jeep was well aware of the car’s vulnerabilities. The problem lies in the ignition – it can be broken out with a screwdriver, after which, the car can be started with a single finger. How’s that for security?

[Mariano] decided that he would take matters into his own hands and add a remote-controlled switch to his car in order to encourage the next would-be thief to move on to an easier target. He describes his creation as a “remote kill” switch, though it’s more of a “remote enable” switch, enabling the engine when he wants to start the car rather than killing it on command.

The switch system is made up of two pieces – a server inside the car’s engine bay, and a remote key fob. The server and the fob speak to one another using IPv6 over 802.15.4 (the same standard used by ZigBee modules). Once the server receives a GET request from the key fob, it authenticates the user with a 128-bit AES challenge/response session, allowing the car to be started.

It is not the simplest way of adding a remote-kill switch to a car, but we like it. Unless the next potential car thief digs under the hood for a while, we’re pretty sure [Mariano’s] car will be safe for quite some time.

Mayor Is A Hacker And Wants To Use DIY Parking Meters

April 8, 2011 by 33 Comments

The Mayor of Silverton, Oregon is a hacker and wants to use roll-your-own hardware in the town’s parking meters. It’s not that he thinks he can do a better job than companies selling modern meters (although there have been notable problems with those), but he wants to retain the sentiment of the 1940’s era parking meters that are being replaced. Those meters are known as penny parking meters, because you can get 12 minutes of time for just one penny.

Many municipalities have gone digital with parking payment systems due to costs associated with servicing mechanical meters and collecting coins from each one of them. This hack aims to keep the look of the vintage meters, but replace the mechanical readout with a digital screen. The meter would still offer a reasonable parking deal; five minutes for free. Cost for replacing the internals is estimated at $150 per meter… which seems just a bit high if they are looking at a 250 unit run. The main problem that we see with the idea is that the original parking meter bodies don’t have a slot which can accept quarters.
