Hitag transponders have been used in a wide variety of car keys as a protective measure against hot-wiring and theft. They’re also a reason why it’s a lot more expensive to get car keys duplicated these days for many models that use this technology. However, there is now an open source programmer that works with these transponder keys, thanks to [Janne Kivijakola].

The hack uses an old reader device salvaged from a Renault in a scrapyard, hooked up to an Arduino Mega 2560 or Arduino Nano. With this setup, key transponders can be programmed via a tool called AESHitager, which runs on Windows. It’s compatible with a variety of Hitag transponders, including Hitag2, Hitag3, and Hitag AES, along with the VVDI Super Chip and certain types of BMW keys.

If you’ve been having issues with coded keys, this project might just be what you need to sort your car out. Everything you need is available on GitHub for those wishing to try this at home. We’ve seen some interesting hacks in this space before, too. Video after the break.

Whether we like it or not, eventually the day will come where we have to admit that we outgrew our childhood toys — unless, of course, we tech them up in the name of science. And in some cases we might get away with simply scaling things up to be more fitting for an adult size. [kenmacken] demonstrates how to do both, by building himself a full-size 1:1 RC car. No, we didn’t forget a digit here, he remodeled an actual Honda Civic into a radio controlled car, and documented every step along the way, hoping to inspire and guide others to follow in his footsteps.

To control the Civic with a standard RC transmitter, [kenmacken] equipped it with a high torque servo, some linear actuators, and an electronic power steering module to handle all the mechanical aspects for acceleration, breaking, gear selection, and steering. At the center of it all is a regular, off-the-shelf Arduino Uno. His write-up features plenty of videos demonstrating each single component, and of course, him controlling the car — which you will also find after the break.

[kenmacken]’s ultimate goal is to eventually remove the radio control to build a fully autonomous self-driving car, and you can see some initial experimenting with GPS waypoint driving at the end of his tutorial. We have seen the same concept in a regular RC car before, and we have also seen it taken further using neural networks. Considering his background in computer vision, it will be interesting to find out which path [kenmacken] will go here in the future.

Nobody’s perfect. Sometimes you’re up late at night writing a blog post and you stumble upon an incredible story. You write it up, and it ends up being, well, incredible. IEEE Spectrum took the bait on this video (embedded below) where [Keran McKenzie] claims to have built a self-driving car for under $1,000 AUS with Arduinos.

The video is actually pretty funny, and we don’t think it’s intended to be a mass-media hoax as much as a YouTube joke. After letting the car “take over” for a few seconds, it swerves and [Keran] pretends to have hit something. (He’s using his knees people!) There are lots of takes with him under the car, and pointing at a single wire that supposedly makes the whole thing work. Yeah, right.


home-built-autonomous-ford-focus-for-under-1000-li86hwunrfmmp4-shot0004We were a bit bummed, though. We don’t think you can even reliably interface a sensor system with the steering wheel, accelerator, and brakes for as little as one grand, but we would have been entirely happy to see it done. We’re not saying that the software to run an autonomous car is the easy part, but we’d love to have a hack at it if the hardware were affordable.

Anyway, if you’re looking for a real autonomous driving experience, we recommend starting by hacking RC cars and giving them substantially bigger brains than an Arduino. Once you’ve got that working, making progress to a real car is doable, but expensive. And it helps to be [geohot].

And lest you think we’re all holier-than-thou, check out our most embarrassing post ever. We could just curl up and die. Feel better soon, IEEE Spectrum!

Thanks [jpiat] for the tip!

As we’ve mentioned previously, the integrity of your vehicle in an era where even your car can have a data connection could be a dubious bet at best. Speaking to these concerns, a soon-to-be published paper out of the University of Birmingham in the UK, states that virtually every Volkswagen sold since 1995 can be hacked and unlocked by cloning the vehicle’s keyfob via an Arduino and software defined radio (SDR).

The research team, led by [Flavio Garcia], have described two main vulnerabilities: the first requires combining a cyrptographic key from the vehicle with the signal from the owner’s fob to grant access, while the second takes advantage of the virtually ancient HiTag2 security system that was implemented in the 1990s. The former affects up to 100 million vehicles across the Volkswagen line, while the latter will work on models from Citroen, Peugeot, Opel, Nissan, Alfa Romero, Fiat, Mitsubishi and Ford.

The process isn’t exactly as simple as putting together $40 of electronics and walking away with a vehicle. The would-be thief must be close in order to detect the fob’s unique key — although they only need to do so once for that vehicle! — as well as reverse-engineer the other half of the code from the vehicle’s internal network. Exploiting HiTag2’s vulnerabilities to unlock the vehicle can be achieved within a minute by a well-prepared thief. [Garcia] and his team note that only the VW Golf 7 has been spared from this exploit.

If thievery is not your thing and you’re looking to white-hat hack your vehicle, Volkswagen still has the best option in the form of the loveable Beetle.

carSelf-driving cars are in the news almost daily, but they are not exactly in my automotive budget for this decade. Today, that has changed. While this car might be smaller and not capable of giving me a ride, it’s still autonomous and, best of all, it is a project that I […]

Too Hot for Fido? Get Alerted!

alert, arduino hacks, car, DHT22, heat, hot, pet, sim900 Commenti disabilitati su Too Hot for Fido? Get Alerted! 

Meet project Oro, the temperature monitoring watchdog. Err… the watchdog monitoring temperature probe. Well, it’s both actually!

[Richard Deininger] built the project after having the AC system go down in his company’s server room. That environmental cooling is imperative if you don’t want your server hardware turned to slag. The idea is a separate piece of hardware that monitors the room temperature and will alert the on-call staff if it climbs too high. He was successful, and showing the hacked hardware around the office came up with a second idea: a temperature sensor for your car to ensure it’s not too hot for your dog.

Anyone who has a canine friend living with them knows you don’t utter the word “ride” out loud lest a barking, whimpering, whining frenzy ensue. But jingle those keys and they’ll be at the door in no time. During the summer you can still take them with you for short errands thanks to the peace of mind [Richard’s] build provides. It’s simply an Arduino, DHT22 temp/humidity probe, and a SIM900 GSM modem. Set your temperature threshold and you’ll get an alert if temperatures are climbing to unsafe levels for Fido.

While you have your tools out, we recommend building auto-watering and auto-feeding systems for the family pets. What’s that? You hate domesticated animals? There’s a hack you can use to chase them from your yard.
