A Bugatti Without The Inconvenience Of Wealth

February 8, 2022 by 52 Comments

There are many of us who might have toyed with the idea of building a car, indeed perhaps more than a few readers might even have taken to the road in a machine of their own creation. Perhaps it was a design of your own, or maybe a kit car. We think that very few of you will have gone as far as [Vũ Văn Nam] and his friends in Vietnam. In their latest video they compress a year’s work into 47 minutes as they craft a beautifully built replica of a Bugatti supercar. If you haven’t got a few million dollars but you’ve got the time, this is the video for you.

The skill involved in making a scratch-built car is impressive enough, but where there guys take it to the next level is in their clay modeling to create the moulds for the fibreglass bodywork. Taking their local clay and a steel frame, they carefully hand-sculpt the car with the skill of an Italian master stylist, before clothing it in fibreglass and removing the clay. The resulting fibreglass shell can be used to make the finished bodywork, which they do with an exceptional attention to detail. It might be a steel-tube home-made spaceframe with a wheezy 4-cylinder Toyota engine behind the driver instead of a 1000 HP powerhouse, but it surely looks the part!

Looking at the construction we’re guessing it wouldn’t pass an Individual Vehicle Approval test for roadworthiness where this is being written, but at the same time it wouldn’t be impossible to incorporate the extra work as this is a proper road-going car. The video is below the break, and though the few pieces of dialogue in it are in Vietnamese you probably won’t need to turn on the auto-translate to follow it.

This isn’t their first fake supercar, there’s already a Ferrari in this particular stable. Meanwhile if you’re of a mind to make a car, consider the world’s most hackable vehicle.

Hacking A Proper Dash Into The Tesla Model 3

January 28, 2022 by 60 Comments

The Tesla Model 3 and Model Y are popular electric vehicles that dispense with some of the usual provisions you’d expect in a typical car. Namely, there’s no dash cluster in front of the driver; instead, all information is solely displayed on the center console screen. [Nick Nguyen] wasn’t a fan of this setup, and decided to hack together a dash cluster of his own. 

The CANdash works in a simple fashion, snooping the Tesla’s CAN bus for all the information relevant to the vehicle’s operation. It’s capable of displaying everything from speed to the remaining range in the battery, while also allowing the user to keep an eye on things like coolant temperatures and whether the Tesla Autopilot system is currently available.

The build relies on a CANserver, an ESP32-based device specifically built for hooking up to the CAN bus on Tesla vehicles and sharing the data externally. The data can then be piped wirelessly to an Android phone running CANdash to display all the desired information. With the help of an aftermarket dash clip or a 3D printed custom mount, the phone can then be placed behind the steering wheel to display data in the usual location.

It’s a simple, straightforward hack that gives Tesla owners a useful feature that they’re otherwise missing from the factory. The US automakers cars are proving to be fertile ground for hackers and DIYers, with one man recently saving thousands on a battery swap with a simple mod. Video after the break.

Does This Lead Make My Car Look Fat?

January 5, 2022 by 64 Comments

When looking at the performance of a vehicle, weight is one of the most important factors in the equation. Heavier vehicles take more energy to accelerate and are harder to stop. They’re also more difficult to control through the corners. Overall, anything that makes a vehicle heavier typically comes with a load of drawbacks to both performance and efficiency. You want your racecar as light as possible.

However, now and then, automakers have found reason to intentionally add large weights to vehicles. We’ll look at a couple of key examples, and discuss why this strange design decision can sometimes be just what the engineers ordered.

The Current State Of Play In Autonomous Cars

December 29, 2021 by 54 Comments

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?

Motorsports Are Turning To Alternative Fuels

December 2, 2021 by 53 Comments

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.

Turn signal monitor

Annoy Yourself Into Better Driving With This Turn Signal Monitor

November 7, 2021 by 44 Comments

Something like 99% of the people on the road at any given moment will consider themselves an above-average driver, something that’s as statistically impossible as it is easily disproven by casual observation. Drivers make all kinds of mistakes, but perhaps none as annoying and avoidable as failure to use their turn signal. This turn signal monitor aims to fix that, through the judicious use of negative feedback.

Apparently, [Mark Radinovic] feels that he has a predisposition against using his turn signal due to the fact that he drives a BMW. To break him of that habit, one that cost him his first BMW, he attached Arduino Nano 33 BLEs to the steering wheel and the turn signal stalk. The IMUs sense the position of each and send that over Bluetooth to an Arduino Uno WiFi. That in turn talks over USB to a Raspberry Pi, which connects to the car’s stereo via Bluetooth to blare an alarm when the steering wheel is turned but the turn signal remains untouched. The video below shows it in use; while it clearly works, there are a lot of situations where it triggers even though a turn signal isn’t really called for — going around a roundabout, for example, or navigating a sinuous approach to a drive-through window.

While [Mark] clearly built this tongue firmly planted in cheek, we can’t help but think there’s a better way — sniffing the car’s CANbus to determine steering angle and turn signal status comes to mind. This great workshop on CANbus sniffing from last year’s Remoticon would be a great place to start if you’d like a more streamlined solution than [Mark]’s.

Ford Maverick Welcomes DIY Spirit

October 12, 2021 by 43 Comments

We’ve featured a lot of car hacks on these pages, most would void the warranty and none of it with explicit factory support. Against that background, Ford’s upcoming Maverick is unique: a major manufacturer has invited owners to unleash their do-it-yourself spirit. It is one of several aspects that led [Jason Torchinsky] of Jalopnik to proclaim The 2022 Ford Maverick Is An Honest, Cheap, Multitool Of A Vehicle And I’m All For It.

There are two primary parts to Ford’s DIY invitation. Inside the cabin are several locations for a dovetail mount called “Ford Integrated Tether System” (FITS). Naturally Ford will be selling their own FITS accessories, but they also expect people to create and 3D-print designs addressing needs unmet by factory kits. CAD files for FITS dimensions are promised, but any maker experienced with a caliper should have little trouble.

Another part of Ford’s DIY invitation is in the cargo area, whose sides were stamped with slots for lumber beams supporting projects like a ~$45 bike rack. There are also threaded bolt holes already in the bed, no drilling or tapping into sheet metal necessary. Behind a few small plastic doors are wires to supply 12 V DC power without the risk of splicing into factory harnesses.

There will always be wild car hacks like turning a sedan into a pickup truck. But it’s great to lower the barrier of entry for milder hacks with these small and very welcome features. QR codes on a sticker takes us to Ford’s collection of video instructions to get things started. Naturally if this idea takes off other people will post many more on their own YouTube channels. We like where Ford wants to go with this, and we would love to see such DIY-friendliness spread across the auto industry. A few Ford videos explaining design intent in this area after the break.
