A DeLorean With An Electrifying Secret

August 16, 2023 by Navarre Bartz 47 Comments

There are few production cars with as much geek cred as the DMC DeLorean. If you want to kick the nerdiness up a notch without doing a full Back to the Future prop-mod, then the next best thing is to make it an EV.

[Bill Carlson] took a 1981 DeLorean and transplanted the drivetrain from a Chevy Bolt to electrify this ride. With the DeLorean being a rear wheel drive vehicle and the Bolt front wheel, there was some amount of component reshuffling to do. The motor is now in the rear of the car along with the main contactor, charger, and motor controller while the batteries are split between a pack in the original engine compartment and another up front under the hood.

The electric power steering and brake booster from the Bolt now also live under the hood, and the accelerator and steering column from the EV were transplanted into the cockpit. [Carlson] still needs to tidy up the interior of the car which is currently a nest of low voltage cables as well as add the cooling system which will bring this stainless monster up to a hefty 3200 lbs (~1450 kg) versus the original 2850 lbs (~1300 kg). We suspect the total bill came in a bit lower than getting an electric DeLorean Alpha5.

This isn’t the first electric DeLorean we’ve covered here, and if that isn’t cool enough, how about this DeLorean-inspired hovercraft?

The Car Of Theseus Boldly Goes Where Many Cars Have Gone Before

August 8, 2022 by Matthew Carlson 45 Comments

We could all use a good chuckle every once in a while. [William Osman] revisited the ship of Theseus in a simplified manner. How many parts can you remove from a car and still be a car? (Video, embedded below the break.)

Of course, there are legal definitions of what a car is and a minimum set of requirements to be met to drive on the road. So, with two older cars ready for hacking and a group of hackers gathered, they split into two teams and started ripping parts of the vehicle. It becomes pretty humorous as it reminds us of many refactoring projects we’ve undertaken. For example, you move one BGA chip, and suddenly, it might be faster to reroute the whole board. Or you remove one component, you have to rip it out of three other modules, which affect four or more other modules, and so on. Accidentally cutting part of the electrical harness meant that one team had to dig further and further into the car to get back to a working car state. It was a race to get back to street legal while taking off more parts.

By the end of the exercise, they have a technically street-legal car they drove around, enjoying passersby’s pointed looks and confusion. They even take it to a dealership to see how much they could get for it. [William] points out that their abysmally low offer proves that a car with less stuff costs less. While we doubt that car manufacturers will follow his lead, it’s a good 15 minutes of fun.

We’ve got you covered if you’re interested in more minimal motoring.

Hong Kong Hacker Builds Electric Vehicle From Waste

Recycled Parts Round Out Soap Shaped Electric Car

November 30, 2021 by Ryan Flowers 13 Comments

[Handy Geng] has a knack for fitting his creations with a large percentage of recycled material. And as is exemplified by the video below the break, he also loves to mix the practical with the whimsical.

Using parts salvaged from motor scooters, trash heaps, and likely many other sources, [Handy] has put together a small vehicle that he himself describes as looking like a bar of soap as it slips across the floor. You’ll agree when you see the independent front and rear steering at work, allowing the car’s front and rear to be driven and steered on their own. Crabbing sideways, driving diagonally, and we’re guessing spinning in place are possible.

What’s also clear in the video below is that [Handy] is a talented fabricator. While not taking himself too seriously (keep an eye out for the 360° selfie cam!) he clearly takes pride in the work. [Handy]’s workshop and skill set show that at the core, he’s quite serious about his craft. We appreciate the creative use of scrap materials used in such an inspiring build. The turn signals and “communicator” hand is absolutely marvelous.

If building with recycled materials is your thing, then you’ll love the Trash Printer, too. Thanks to [Fosselius] for the tip!

Quick And Dirty Immobilizer Hack Lets You Use Cheaper Dumb Keys

April 10, 2019 by Lewin Day 34 Comments

Car enthusiasts can find themselves in a pickle if they’re into cars from the 80s and 90s. These vehicles are much beloved by some, but one can find themselves having to fork out immense amounts of money for repairs and out-of-production parts. Once a car passes that 15 year milestone, suddenly manufacturer support can start to dry up. Even just getting a set of keys can be a problem.

Modern cars tend to use a small chip implanted in the key as a security measure. This chip functions similarly to an RFID chip, being energised by the car’s reader when the driver turns the key in the ignition. If the chip returns the right code, the computer allows the car to start. Getting a new key cut and recoded is expensive, particularly on older cars. Naturally though, there’s a way to hack around the problem.

The trick is to perform surgery on an existing good key, to extract the working chip inside. This chip can then be permanently affixed to the immobilizer’s antenna in the steering column. This allows the driver to use any properly cut “dumb” key to start the car, as the chip will always provide the right signal at startup. It takes some finesse to avoid damaging the delicate chip inside and to know where to look – but with a little work, it’s achievable by even the novice hacker.

It’s a simple hack that can save hundreds of dollars, and is a great way to keep your modern classic on the road for cheap. You can always take things a step further though, and CNC yourself a key from scratch if you’re so inclined.

Turning A Car Into A Computer Mouse

February 18, 2018 by Steven Dufresne 20 Comments

[William Osman] and [Simone Giertz] have graced our pages before, both with weird, wacky and wonderful hacks so it’s no surprise that when they got together they did so to turn Simone’s car into a computer mouse. It’s trickier than you might think.

They started by replacing the lens of an optical mouse with a lens normally used for a security camera. Surprisingly, when mounted to the car’s front bumper it worked! But it wasn’t ideal. The problem lies in that to move a mouse cursor sideways you have to move the mouse sideways. However, cars don’t move sideways, they turn by going in an arc. Move your mouse in an arc right now without giving it any sideways motion and see what happens. The mouse cursor on the screen moves vertically up or down the screen, but not left or right. So how to tell if the car is turning? For that, they added a magnetometer. The mouse then gives the distance the car moved and the magnetometer gives the heading, or angle. With some simple trigonometry, they calculate the car’s coordinates.

The mouse click is done using the car’s horn, but details are vague there.

And yes, using the carmouse is as fun as it sounds, though we still don’t recommend texting while driving using this technique. Watch them in the videos below as they write an email and drive a self-portrait of the car.

Salvaging Your Way To A Working Tesla Model S For $6500

September 20, 2017 by Adil Malik 80 Comments

If you possess modest technical abilities and the patience of a few dozen monks, with some skillful haggling you can land yourself some terrific bargains by salvaging and repairing. This is already a well-known ideology when it comes to sourcing things like electronic test gear, where for example a non working unit might be purchased from eBay and fixed for the price of a few passive components.

[Rich] from Car Guru has taken this to a whole new level by successfully salvaging a roadworthy Tesla Model S for $6500!

Sourcing and rebuilding a car is always a daunting project, in this case made even more challenging because the vehicle in subject is fairly recent, state of the art electric vehicle. The journey began by purchasing a black Tesla Model S, that [Rich] affectionately refers to as Delorean. This car had severe water damage rendering most of its electronics and mechanical fasteners unreliable, so [Rich’s] plan was to strip this car of all such parts, and sell what he could to recover the cost of his initial purchase. After selling the working modules of the otherwise drenched battery, motor and a few other bells and whistles his initial monetary investment was reduced to the mere investment of time.

With an essentially free but empty Tesla shell in his possession, [Rich] turned his attention to finding a suitable replacement for the insides. [Rich] mentions that Tesla refused to sell spare parts for such a project, so his only option was to purchase a few more wrecked vehicles. The most prominent of these wrecks was nicknamed Slim Shady. This one

had an irreparable shell but with most electronics preserved, and would serve as the donation vehicle. After painstakingly transplanting all the required electronics and once again selling what he did not need, his net investment came to less than 10% of a new car!

Was all of the effort worth it? We certainly think it was! The car was deemed road worthy and even has functioning Super Charging capabilities which according to [Rich] are disabled by Tesla if such a Frankenstein build is detected.

At this point it would probably be instructive to ask [Rich] if he would do it again, but he is already at it, this time salvaging the faster self driving P86. We suggest you stay tuned.

[Thankyou to Enio Fernandes for sending in the tip]

Blackberry Eyes Up Car Anti-Virus Market

May 19, 2017 by Jack Laidlaw 73 Comments

[Reuters] reports that BlackBerry is working with at least two car manufacturers to develop a remote malware scanner for vehicles, On finding something wrong the program would then tell drivers to pull over if they were in critical danger.

The service would be able to install over-the-air patches to idle cars and is in testing phase by Aston Martin and Range Rover. The service could be active as early as next year, making BlackBerry around $10 a month per vehicle.

Since the demise of BlackBerry in the mobile phone sector, they’ve been hard at work refocusing their attention on new emerging markets. Cars are already rolling computers, and now they’re becoming more and more networked with Bluetooth and Internet connections. This obviously leaves cars open to new types of attacks as demonstrated by [Charlie Miller] and [Chris Valasek]’s hack that uncovered vulnerabilities in Jeeps and led to a U.S. recall of 1.4 million cars.

BlackBerry seem to be hedging their bets on becoming the Kingpin of vehicle anti-virus. But do our cars really belong on the Internet in the first place?
