Every few years, someone pushing a startup to investors comes up with an acronym or buzzword which rapidly becomes the new hotness in those circles. One of the most pernicious is “as a Service,” which takes regular things and finds a way to charge you a regular fee to use them.
Automotive companies just absolutely loved the sound of this, and the industry is rapidly moving to implement subscription services across the board. Even if there’s hardware in your car for a given feature, you might find you now need to pay a monthly fee to use it. Let’s explore how this came about, and talk about which cars are affected. You might be surprised to find yours already on the list. Continue reading “New Cars Will Nickel-and-Dime You – It’s Automotive As A Service”→
Bluster around the advent of self-driving cars has become a constant in the automotive world in recent years. Much is promised by all comers, but real-world results – and customer-ready technologies – remain scarce on the street.
Today, we’ll dive in and take a look at the current state of play. What makes a self-driving car, how close are the main players, and what can we expect to come around the corner?
If you’ve spent any time around the modified car scene in the last few years, you’ve probably heard about E85. Maybe you’ve even noticed a sweet smell emanating from the pitlane, or heard people cracking jokes about “corn juice.”
The blended fuel, which combines alcohol and traditional gasoline, can have significant performance benefits if used properly. Today, we’ll explore what those are, and how you can set your ride up to run on E85.
Tesla is well known for making cars that can accelerate quickly, but there’s always room for improvement. [Warped Perception] decided that his Tesla Model S P85D needed that little bit of extra oomph (despite the 0-60 MPH or 0-97 km/h time of 3.1 seconds), so he did what any sensible person would: add three jet turbines to the back of his car.
The best part of this particular build is the engineering and fabrication that made this happen. With over 200 pieces and almost all personally fabricated, this is a whirlwind of a build. The control panel is first, and there’s a particularly clever technique of 3D printing the lettering directly onto the control panel for the flat stuff. Then for the pieces with angles that would prevent the head from moving freely, he printed onto a plastic sheet in reverse, applied glue, then stuck the letters to the plate as a sheet. A top layer of clear coat ensures the letters won’t come off later.
Using a 3D printer to apply lettering on the control panel.
He installed the control electronics in the trunk with wiring strung from the car’s front to the rear. Three Arduinos serve as controllers for the jets. Afterward, came the bracket to hold the engines and attach it to the car’s underside. Unfortunately, supplies were a little hard to come by, so he had to make do with what was on hand. As a result it didn’t come out as strong as he would have hoped, but it’s still pretty impressive.
[Warped Perception] does a few tests before taking it out on the road. Then, he shifted the car into neutral and could drive the car solely on jet power, which was one of his goals. While we don’t love the idea of testing a jet engine on public roads, it certainly would discourage tailgaters.
Next, he finds a quieter road and does some speed tests. Unfortunately, it was drizzling, and the pavement was damp, putting a damper on his 0-60 standing times. Electric-only he gets 4.38 seconds, and turning on the jets plus electric shaves that down to 3.32 seconds. Overall, an incredible build that’s sure to draw a few curious glances whenever you’re out on the town.
As the world grapples with the issue of climate change, there’s a huge pressure to move transport away from carbon-based fuels across the board. Whether it’s turning to electric cars for commuting or improving the efficiency of the trucking industry, there’s much work to be done.
It’s a drop in the ocean in comparison, but the world of motorsports has not escaped attention when it comes to cleaning up its act. As a result, many motorsports are beginning to explore the use of alternative fuels in order to reduce their impact on the environment.
Sales of electric vehicles continue to climb, topping three million cars worldwide last year. All these electric cars need batteries, of course, which means demand for rechargeable cells is through the roof.
All those cells have to come from somewhere, of course, and many are surprised to learn that automakers don’t manufacture EV batteries themselves. Instead, they’re typically sourced from outside suppliers. Today, you get to Ask Hackaday: why aren’t EV batteries manufactured by the automakers themselves?

[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!
