Simple PCB Repairs Keep Old Vehicle Out Of The Crusher

October 24, 2024 by 21 Comments

For those of us devoted to keeping an older vehicle on the road, the struggle is real. We know that at some point, a part will go bad and we’ll learn that it’s no longer available from the dealer or in the aftermarket, at least at a reasonable cost. We might get lucky and find a replacement at the boneyard, but if not — well, it was nice knowing ya, faithful chariot.

It doesn’t have to be that way, though, at least if the wonky part is one of the many computer modules found in most cars made in the last few decades. Sometimes they can be repaired, as with this engine control module from a Ford F350 pickup. Admittedly, [jeffescortlx] got pretty lucky with this module, which with its trio of obviously defective electrolytics practically diagnosed itself. He also had the advantage of the module’s mid-90s technology, which still relied heavily on through-hole parts, making the repair easier.

Unfortunately, his luck stopped there, as the caps had released the schmoo and corroded quite a few traces on the PCB. Complicating the repair was the conformal coating on everything, a common problem on any electronics used in rough environments. It took a bit of probing and poking to locate all the open traces, which included a mystery trace far away from any of the leaky caps. Magnet wire was used to repair the damaged traces, the caps were replaced with new ones, and everything got a fresh coat of brush-on conformal coating.

Simple though they may be, we really enjoy these successful vehicle module repairs because they give us hope that when the day eventually comes, we’ll stand a chance of being able to perform some repair heroics. And it’s nice to know that something as simple as fixing a dead dashboard cluster can keep a car out of the crusher.

Will You Need Ad Block For Your Car?

September 24, 2024 by 113 Comments

The modern web has become difficult to navigate without ad blocking software. Ford now has a patent application that would bring the ads we hate to your vehicle’s infotainment system. [via PCMag]

Ford has already replied to criticism with the usual corporate spiel of patents not necessarily being the direction the company will go with future products, but it’s hard to imagine that other automakers aren’t planning similar systems since they’re already charging extra for heated seats, EV range, and performance. Bringing ads to the captive audience of your personal vehicle and targeting them based on listening to the occupants’ conversations would be a new low. Maybe you’ll be able to pay an extra $100/month for the “ad-free experience.”

Instead of taking advantage of the EV transition to make better, simpler cars, automakers are using their highly-computerized nature to extract more from you and provide less when you drive off the lot. Enshittification has come for the automobile. Perhaps auto executives should read A Few Reasonable Rules for the Responsible Use of New Technology?

The first step of blocking these ads will likely be jailbraking the infotainment system. If that wasn’t enough, locking features behind a paywall has come for wheelchairs too.

Retrotechtacular: Ford Model T Wheels, Start To Finish

July 18, 2024 by 20 Comments

There’s no doubt that you’ll instantly recognize clips from the video below, as they’ve been used over and over for more than 100 years to illustrate the development of the assembly line. But those brief clips never told the whole story about just how much effort Ford was forced to put into manufacturing just one component of their iconic Model T: the wheels.

An in-house production of Ford Motors, this film isn’t dated, at least not obviously. And with the production of Model T cars using wooden spoked artillery-style wheels stretching from 1908 to 1925, it’s not easy to guess when the film was made. But judging by the clothing styles of the many hundreds of men and boys working in the River Rouge wheel shop, we’d venture a guess at 1920 or so.

Production of the wooden wheels began with turning club-shaped spokes from wooden blanks — ash, at a guess — and drying them in a kiln for more than three weeks. While they’re cooking, a different line steam-bends hickory into two semicircular felloes that will form the wheel’s rim. The number of different steps needed to shape the fourteen pieces of wood needed for each wheel is astonishing. Aside from the initial shaping, the spokes need to be mitered on the hub end to fit snugly together and have a tenon machined on the rim end. The felloes undergo multiple steps of drilling, trimming, and chamfering before they’re ready to receive the spokes.

The first steel component is a tire, which rolls down out of a furnace that heats and expands it before the wooden wheel is pressed into it. More holes are drilled and more steel is added; plates to reinforce the hub, nuts and bolts to hold everything together, and brake drums for the rear wheels. The hubs also had bearing races built right into them, which were filled with steel balls right on the line. How these unsealed bearings were protected during later sanding and grinding operations, not to mention the final painting step, which required a bath in asphalt paint and spinning the wheel to fling off the excess, is a mystery.

Welded steel spoked wheels replaced their wooden counterparts in the last two model years for the T, even though other car manufacturers had already started using more easily mass-produced stamped steel disc wheels in the mid-1920s. Given the massive infrastructure that the world’s largest car manufacturer at the time devoted to spoked wheel production, it’s easy to see why. But Ford eventually saw the light and moved away from spoked wheels for most cars. We can’t help but wonder what became of the army of workers, but it probably wasn’t good. So turn the wheels of progress.

Reverse Engineering Keeps Early Ford EVs Rolling

June 7, 2024 by 5 Comments

With all the EV hype in the air, you’d be forgiven for thinking electric vehicles are something new. But of course, EVs go way, way back, to the early 19th century by some reckonings. More recently but still pretty old-school were Ford’s Think line of NEVs, or neighborhood electric vehicles. These were commercially available in the early 2000s, and something like 7,200 of the slightly souped-up golf carts made it into retirement communities and gated neighborhoods.

But as Think aficionado [Hagan Walker] relates, the Achille’s heel of these quirky EVs was its instrument cluster, which had a nasty habit of going bad and taking the whole vehicle down with it, sometimes in flames. So he undertook the effort of completely reverse engineering the original cluster, with the goal of building a plug-in replacement.

The reverse engineering effort itself is pretty interesting, and worth a watch. The microcontroller seems to be the primary point of failure on the cluster, probably getting fried by some stray transients. Luckily, the microcontroller is still available, and swapping it out is pretty easy thanks to chunky early-2000s SMD components. Programming the MCU, however, is a little tricky. [Hagan] extracted the code from a working cluster and created a hex file, making it easy to flash the new MCU. He has a bunch of other videos, too, covering everything from basic diagnostics to lithium battery swaps for the original golf cart batteries that powered the vehicle.

True, there weren’t many of these EVs made, and fewer still are on the road today. But they’re not without their charm, and keeping the ones that are still around from becoming lawn ornaments — or worse — seems like a noble effort.

Oh, perfect — now our cars can BSOD. At least that’s how it looks from a forum post showing a Blue Screen of Death on a Ford Mustang Mach E, warning that an over-the-air software update failed, and now the car can’t be driven. The BSOD includes a phone number to reach Ford’s Customer Relationship Center and even presents a wall of text with specific instructions to the wrecker driver for loading the bricked vehicle onto a flatbed. Forum users questioned the photo’s veracity, but there are reports of other drivers getting bricked the same way. And we’ve got to point out that even though this specific bricking happened to an EV, it could just have easily happened to an ICE vehicle too; forum members were particularly prickly about that point. It would be nice if OTA software updates on vehicles could always roll back to the previous driveable state. Still, we suppose that’s not always possible, especially if memory gets corrupted during the update. Maybe the best defense against a bricked vehicle would be to keep a beater around that doesn’t need updates to keep running.

Sure, it does less than originally promised, but hey — at least it’s more expensive. That about sums up Tesla fans’ feelings after the long-awaited Cybertruck reveal at the Texas Gigafactory on Thursday, where Elon Musk himself handed over the keys — or their Cyber equivalent — to a few new owners. These are expensive machines — $61,000 for the two-motor model, and just shy of $100,000 for the three-motor all-wheel-drive model with all the bells and whistles. That’s considerably more than they were expected to cost back in 2019, a fact which may be at least partially behind the drop in Tesla shares after the launch.

When Tail Lights Lose Touch With Reality

September 9, 2023 by 129 Comments

To study the history of the automobile is to also be a student of technological progress — as with each decade’s models come new innovations to make them better handling, more corrosion-resistant, faster, more efficient, or whatever the needs of the moment dictate. But sometimes that technological advancement goes awry and works against the motorist, making for a vehicle that’s substantially worse than what went before. [FordTechMakuloco] has a video with an example in a Ford pickup, which we believe deserves to be shared.

The problem with the vehicle was simple enough, indeed it’s one we’ve had in the past ourselves. Water got into a tail light, and corroded some connectors. The difference with this Ford though was that such a simple fault took out the whole car, and that the fix for a simple tail light cost $5600. The first was due to a vehicle-wide CAN bus going down due to the electrical short, and the second was due to the assembly containing an assortment of wiring and modules which couldn’t be replaced separately. These included some form of side-facing parking radar, a component unnecessary for operation of the light itself. Some relatively straightforward design and component supply decisions such as separating subsystems across multiple CAN busses, ensuring individual modules are separately available, and even designing connectors to face downwards and self-drain, could have fixed it, but the automaker chose instead to build in some planned obsolescence. Would you buy a Ford truck after seeing the video below the break?

We’ve written here before about how automotive design has taken this wrong path, and even advanced a manifesto as to how they might escape it. This Ford tail light seems to us an egregious example of electronics-as-the-new-rust rendering what should be a good vehicle into a badly designed piece of junk, and honestly it saddens us to see it. Oddly, there was once a time when a Ford truck was about as good as you could get.
