Are There Better Things To Hurl Into Orbit Than A Sports Car?

We’ve been having a lively discussion behind the scenes here at Hackaday, about SpaceX’s forthcoming launch of their first Falcon Heavy rocket. It will be carrying [Elon Musk]’s red Tesla Roadster, and should it be a successful launch, it will place the car in an elliptical orbit round the Sun that will take it to the Martian orbit at its furthest point.

On one hand, it seems possible that [Musk]’s sports car will one day be cited by historians as the exemplar of the excesses of the tech industry in the early 21st century. After all, to spend the millions …read more

Tesla Model S Battery Pack Teardown

We’ve heard a lot about the Tesla Model S over the last few years, it’s a vehicle with a habit of being newsworthy. And as a fast luxury electric saloon car with a range of over 300 miles per charge depending on the model, its publicity is deserved, and that’s before we’ve even mentioned autonomous driving  driver-assist. Even the best of the competing mass-produced electric cars of the moment look inferior beside it.

Tesla famously build their battery packs from standard 18650 lithium-ion cells, but it’s safe to say that the pack in the Model S has little in common …read more

At Last, An Open Source Electric Vehicle From A Major Manufacturer

There is a rule of thumb to follow when looking at product announcements at the fringes of the motor industry that probably has something in common with crowdfunding campaigns. If the photographs of the product are all renders rather than real prototypes, walk away. It is said that small volume vehicle production is a space that attracts either crooks or dreamers, and parting with your money to either can be a risky business. So when yet another electric vehicle platform makes its debut it’s always worth looking, but too often the rendered images outnumber anything from the real world and …read more

Cheap Electric Car Drives Again with Charger Repair

If someone sent you an advert for an electric car with a price too low to pass up, what would you do? [Leadacid44] was in that lucky situation, and since it was crazy cheap, bought the car.

Of course, there’s always a problem of some kind with any cheap car, and this one was no exception. In this case, making it ‘go’ for any reasonable distance was the problem. Eventually a faulty battery charging system was diagnosed and fixed, but not before chasing down a few other possibilities. While the eventual solution was a relatively simple one the write-up of …read more

Massive 20-oz. Copper PCB Enables Electric Racing

Is twenty times the copper twenty times as much fun to work with? Ask [limpkin] and follow along as he fabricates a DC/DC block for a Formula E race car on 20-oz copper PCBs.

The typical boards you order from OSH Park and the like usually come with 1-ounce copper – that’s one ounce of copper cladding per square foot of board. For those averse to Imperial units, that’s a copper layer 34 micrometers thick. [limpkin]’s Formula E control board needs to carry a lot of current, so he specified 700-micrometer thick cladding, or 20-oz per square foot. The board …read more

EV History: The Lightning Precedes The Thunder

In 1988, a bunch of engineers from Hotzenwald, East Germany, came together and decided that it is time for the future of mobility: A new, more modern and environmentally friendly car should put an end to fossils and emissions while still being fun to drive. “It should become a new kind of car. Smaller, lighter, cleaner – and more beautiful” is how future CEO Thomas Albiez described his mission. For the first time in automotive history, this series car would be designed as an all-electric vehicle from the start and set a new standard for mobility. The project was given …read more
