#do-it-yourself

Anything that happens in Australia is already sort of funny, because we all remember the Simpsons episode where the Aussie locals play knifey-spoony and Homer salutes the toilet.

Well, from the land of Midnight Oil, Nicole Kidman and the defunct Ford Falcon Ute comes this story, thanks to Jalopnik, the South Australia Police, and a man who wouldn’t let a missing steering wheel end his motoring dreams.

If this catches on, local governments will have to choose between anarchy and saving on infrastructure repair.

An 84-year-old man in rural Nova Scotia, Canada just did what many of us have always fantasized about — he rolled out his own heavy equipment to fix the road in front of his house, according to Global News.

Preston Perry of Upper Nine Mile River was sick to death of the suspension-bending potholes in his gravel roadway, and — like Charles Bronson in any movie starring Charles Bronson — stormed out the door to take matters into his own hands.

It’s taken a while to get started on the project to make my daily driver Saturn SL1 into a better handling car. I had the parts but it took a few weeks to be able to get the work scheduled at a shop that was willing to install my own components. Now that the work has been done and I’ve been able to drive the car in varying conditions, it’s time for a progress report. The short version is that I’m pleased with the results. For the long version, continue reading after the break.

When cars started getting digitized, first with fuel injection, then electronic ignition and ECUs, some enthusiasts thought that would foretell the end of hot rodding. That’s proved to be a false prophecy, what with developments like the Megasquirt engine management system, high performance “chips” and tuning via the OBD port. Last year, Ford Motor Company, which has been at the leading (some say bleeding) edge of in-car electronics and infotainment, announced the release of the OpenXC Platform. OpenXC is an application progrmaming interface, API, that makes information from the car’s various instruments and sensors available to Android applications. The idea was to open up that information to all the possibilities with which open source application developers and hobbyists might come up. The system is read only, to prevent you from damaging your car, or worse, creating an unsafe driving situation, but in terms of using that information, the possibilities are endless. To promote OpenXC, Ford has released a video of a haptic shift indicator, built into the shift knob, invented by one of their junior engineers, Zach Nelson. When you feel it vibrate, it’s time to shift.

Using a haptic feedback motor from an Xbox 360 controller, an Arduino controller, and an Android based tablet with some USB and Bluetooth hardware Nelson created a programmable haptic shift indicator that he then built into a custom shift knob that he had designed in a CAD program and printed out with a MakerBot Thing-O-Matic 3D printer.

Using engine speed, throtle position, and other engine control data, Nelson programmed different modes that tell the driver when it’s ideal to shift up (or theoretically, down as well, I suppose, if you add in data from the traction control systems). Programmed for performance, the shift knob will vibrate when approaching redline and if economy is what the driver is after, it will buzz at the best shift point for optimum fuel mileage, it can even have a tutorial mode to help drivers learn how to shift a manual transmission. For “fun”, Nelson installed a LED display on the top of his custom shifter that shows the gear position.

As part of the open source ethos, Nelson and Ford have made all of his design files, the firmware, the Android application for programming the device, and the CAD file for the shifter knob, available to the public with links at the OpenXC site. The idea is to let enthusiasts further develop the idea.

OpenXC will be available for a growing number of Ford vehicles. In the video, Nelson says that the latest car he’s tested it on is the Shelby GT500 Mustang. He talks of his sense of accomplishment when his invention worked with the 662 horsepower muscle car. My guess is that in that particular app, he had it programmed to shift at redline.

Yesterday was my day off, and by “day off” I of course mean, “day in which I work my ass off sans remuneration”. No doubt this’ll strike a chord with those of you who also have older houses with plenty of, uh, character.

It was a day no thumbs would die by accidental hammer-blow: there was work to be done on the car, and they don’t call me “Spanner” McAleer just because I’m a bit of idiot. Actually, maybe they do – well anyway, to arms!
