Predicting Weather with the Internet of Cars

Posted on by

Follow this train of thought: cars have sensors, cars are infrequent use over large areas, cars are the ultimate distributed sensor network for weather conditions.

Many years ago, as I wasted yet another chunk of my life sitting in the linear parking lot that was my morning commute, I mused that there had to be a way to prevent this madness. I thought: What if there was a way for the cars to tell each other where slowdowns are? This was long before smartphones, so it would have to be done the hard way. I imagined that each vehicle could …read more

Juicing Up the Chevy Volt with Raspberry Pi

Posted on by

While Chevrolet’s innovative electric hybrid might officially be headed to that great big junkyard in the sky, the Volt will still live on in the hearts and minds of hackers who’d rather compare amp hour than horsepower. For a relatively low cost, a used Volt offers the automotive hacker a fascinating platform for upgrades and experimentation. One such Volt owner is [Jared Stafford], who’s recently made some considerable headway on hacking his hybrid ride.

In an ongoing series on his blog, [Jared] is documenting his efforts to add new features and functions to his Volt. While he loves the car …read more

The Thrill of Building Space Hardware to Exceptionally High Standards

Posted on by

It’s fair to say that the majority of Hackaday readers have not built any hardware that’s slipped the surly bonds of Earth and ventured out into space proper. Sure we might see the occasional high altitude balloon go up under the control of some particularly enterprising hackers, but that’s still a far cry from a window seat on the International Space Station. Granted the rapid commercialization of space has certainly added to that exclusive group of space engineers over the last decade or so, but something tells us it’s still going to be quite some time before we’re running space-themed …read more

A Fully Automatic Electric Can Crusher

Posted on by

Those of us who recycle our empty drink cans know the annoying storage problem these containers present. For an object with very little metal, a can takes up a huge amount of space, and should you possess a greater than average thirst you can soon end up with a lot of space taken up with stacks of cans. The solution of course is to crush them, and while there are many simple solutions involving hinged blocks of wood or lever systems, this is 2019! We have Machines to that kind of thing for us! [All Things Electro-Mechanical] thinks so …read more

Emulating OBD-II on the ESP32

Posted on by

It used to be that you could pop the hood and with nothing more than flat head screwdriver, some baling wire, and tongue held at the optimal angle, you could fix anything that ailed your car. But today, for better or for worse, the average automobile is a rolling computer that runs on gasoline and hope (if it even still has a gasoline engine, that is). DIY repairs and maintenance on a modern car is still possible of course, but the home mechanic’s toolbox has needed to evolve with the times. If you want to do anything more advanced than …read more

Hackaday Links: May 21, 2017

Posted on by

It’s time to talk about something of supreme importance to all Hackaday readers. The first trailer for the new Star Trek series is out. Some initial thoughts: the production values are through the roof, and some of this was filmed in Jordan (thank the king for that). The writers have thrown in some obvious references to classic Trek in this trailer (taking a spacesuit into a gigantic alien thing a la TMP). There are a few new species, even though this is set about 10 years before waaaait a second, those are the Klingons?

In other news, [Seth MacFarlane] is …read more

Reverse Engineering the Smart ForTwo CAN Bus

Posted on by

The CAN bus has become a defacto standard in modern cars. Just about everything electronic in a car these days talks over this bus, which makes it fertile ground for aspiring hackers. [Daniel Velazquez] is striking out in this area, attempting to decode the messages on the CAN bus of his Smart ForTwo.

[Daniel] has had some pitfalls – first attempts with a Beaglebone Black were somewhat successful in reading messages, but led to strange activity of the car and indicators. This is par for the course in any hack that wires into an existing system – there’s a high …read more

First Look: Macchina M2

Posted on by

In the past few years, we’ve seen a growth in car hacking. Newer tools are being released, which makes it faster and cheaper to get into automotive tinkering. Today we’re taking a first look at the M2, a new device from the folks at Macchina.

The Macchina M1 was the first release of a hacker friendly automotive device from the company. This was an Arduino compatible board, which kept the Arduino form factor but added interface hardware for the protocols most commonly found in cars. This allowed for anyone familiar with Arduino to start tinkering with cars in a familiar …read more

Hacking The Tesla Model S Rear Drive Unit

Posted on by

[Jason Hughes] is a big fan of Tesla, he’s spent a lot of time hacking on them to figure out what fancy things the automaker is up to. His most recent adventures are with the rear drive unit of a Tesla Model S.

[Jason] has had some fame in the Tesla community before; his most publicized hack was finding the model number for Tesla’s next edition of their car hashed away in the firmware. For this project he procured a rear drive unit from… somewhere, and with some help got it onto his bench at home.

His first steps were …read more
