Fail of the Week: How Not to Electric Vehicle

If you ever doubt the potential for catastrophe that mucking about with electric vehicles can present, check out the video below. It shows what can happen to a couple of Tesla battery modules when due regard to safety precautions isn’t paid.

The video comes to us by way of [Rich], a gearhead with a thing for Teslas. He clearly knows his way around the EV world, having rebuilt a flood-soaked Tesla, and aspires to open an EV repair shop. The disaster stems from a novelty vehicle he and friend [Lee] bought as a side project. The car was apparently once …read more

Belt Up With A Redundant Car Part

The toothed belt that turns the camshaft in synchronization with the crankshaft on many motor vehicle engines is something of an under-appreciated component. Unless you are unlucky enough to ave had one fail and destroy your engine, it’s probably something you’ve never given a second thought to outside of periodic service intervals.

For something to perform such a task over so many thousands of miles of motoring it must be made of pretty strong stuff. Even when a belt is life-expired it is still in good physical shape, and [Crispyjones] saw the potential in a used Subaru belt to make …read more

Ford Ka Becomes Diwheel Monster

If you’ve been to the right events, you’ve seen them before – the cars with an external cage that let the car complete a somersault in the forward direction under heavy braking. They’re impressive, but it’s possible to take things even further. Enter [mastermilo82] and the RollKa.

The RollKa follows on from the RollGolf, which was a straightforward roll car build. Built around a Ford Ka, it eschews the external cage for a more radical design. The Ka has been shortened, and designed to fit within two enormous steel rims which wrap around each side of the car. Additional idler …read more

Toil in Style With Salvaged Porsche Office Chairs

It seems as if everyone has finally decided to stop pretending that standing in front of a desk for 8+ hours was something anyone actually wanted to do, and once again embrace the classic adjustable office chair. But whether you’re writing code in a cubicle or are one of those people who apparently makes a living by having people watch them play video games, one thing is certain: your chair needs to be cool enough to make up for the years shaved off your life by sitting in it all day.

Case in point, these chairs that were made out …read more

Car Hacking at DEF CON 26

A great place to get your feet wet with the data-network-wonderland that is modern-day automobiles is the Car Hacking Village at DEF CON. I stopped by on Saturday afternoon to see what it was all about and the place was packed. From Ducati motorcycles to junkyard instrument clusters, and from mobility scooters to autonomous RC test tracks, this feels like one of the most interactive villages in the whole con.

The Obvious: CAN Bus Hacking

When I think of car hacking, CAN bus is the first thing that pops to mind. CAN is the protocol used for the data network …read more

Printed Part Gets Classic Truck Rolling

When working on classic vehicles, and especially when modifying them outside of their stock configurations, things can get expensive. It’s a basic principle in economics: the rarer something is the more money somebody can charge you for it. But if you’ve got the skills and the necessary equipment, you can occasionally save yourself money by custom-fabricating some parts yourself.

After changing the gear ratio in his 1971 Ford F100, [smpstech] needed to adjust his speedometer to compensate. Unfortunately, a commercial speedometer reducer and the new cables to get it hooked up to his dash would have run into the hundreds …read more

Voltage Monitor Relay is More than Meets the Eye

Automotive components that have a hidden secondary function are usually limited to cartoons and Michael Bay movies, but this project that [Jesus Echavarria] created for a client is a perhaps as close as we’re likely to get in the near future. The final product certainly looks like a standard automotive relay, but a peek inside the 3D printed case reveals a surprisingly complex little device. It’s still technically a relay, but it uses a PIC microcontroller to decide when it should activate.

[Jesus] was given the task of creating a device that would fit into the relay box of a …read more
