There is something wrong with the tractor. The water-in-fuel sensor, a small device embedded in the John Deere machine that monitors the integrity of its diesel engine, is disconnected. And I’ve got to fix it.

I’m not a mechanic or a farmer. I’m poking at a laptop at John Deere’s corporate office in Santa Clara, California. There’s a cable connecting the computer to a 5130ML tractor sitting on the grass nearby. A bright red notification sits on the screen, telling me something is wrong. I type in a question and the software pulls up instructions and a few images from the user manual that matches the serial number of the machine.

Although we often find ourselves drowning in a seemingly unending sea of portable devices that are effectively e-waste once an internal component gives out, it’s good to remind ourselves that there are a few examples out there by large brands that manage to tick all the fancy feature boxes, while still being very much repairable. Case in point the Pixel Watch 5, a smart watch which much like its predecessor gets a 9/10 on [iFixit]’s repairability score.

Despite featuring an IP68 rating, opening it is as easy as taking out a few screws to release its latch. This allows the back to swing open, with not a drop of glue in sight, just an O-ring gasket that keeps moisture out and can be reused many times. Digging into the guts, there are color-coded screws that guide one’s hand as the very modular design is taken apart in a matter of minutes.

Being able to simply unlatch the back, and also easily obtain spare parts are two aspects that are a very welcome sight indeed. Although it’s much easier to just glue everything together, something like this latch-and-gasket approach is something that we hope that more manufacturers will copy for these small devices.

It’s potentially also an idea for one’s next DIY smart watch project, as tempting as reaching for that tube of glue may seem.

After the [Slow Mo Guys] acquired a 168 TB Seagate LaCie Thunderbolt 3-based RAID storage system back in 2019 to store their video footage, they were obviously slightly miffed when suddenly it would just refuse to power up. Naturally the device was now out of warranty, the product itself no longer produced and Seagate support was less than supportive, ergo they sent the device to [Mend it Mark] for an attempted repair.

At first inspection the device appeared to be basically unresponsive, with none of the four fans running and no signs of life other than a few lit LEDs on the main PCB after supplying power to it. After full disassembly and with no repair guide or schematics to go by [Mark] had to start from basics, first diagnosing whether all the power rails were turning on, which they weren’t.

Eventually this led to the NXP LPC11U6x-series MCU which acts as the main power management and monitoring chip in the system. [Mark] deduced that this MCU wasn’t turning on all the power rails because it was waiting for a signal from the fan controllers on the SATA backplane. With the MCU sending the right signals here, and the fans all working when directly supplied with power, ultimately it turned out that a single SI2319 or similar P-channel MOSFET in SOT-23 package near one of the fan connectors had gone faulty.

Replacing this one MOSFET seems to have fixed the RAID array, with it now happily powering up, although the real test will be once the [Slow Mo Guys] start shoving the HDDs back into it. Assuming that this was the sole fault in the system, then it was a very cheap fix in terms of materials. It’s a real shame that repair guides or schematics aren’t made available for devices like this, even if just after they stop being produced.

Smartphone longevity didn't used to matter. In the past, before you could wear out or break a phone, there was always some shiny new thing to buy. Today, we expect our smartphones to go the distance, but they've also become less repairable and, in many cases, more fragile. Fairphone, a Dutch smartphone maker that has just entered the US market, thinks about phones differently.

The new $650 Fairphone Gen 6+ is designed both for longevity and easy repairability. There are trade-offs to this approach if you're used to the standard glass and aluminum sandwiches filled with glue, gaskets, and teeny-tiny screws. But the drawbacks could be worth it for the right buyer. Fairphone CTO Chandler Hatton told Ars that Fairphone's goal is to provide a compelling mobile experience while also enabling the user to "fully own" their device. At the end of the day, this is what a lot of people say they want in a smartphone.

Take it apart, put it back together

These days, Google, Samsung, and Apple support phones with software updates for the better part of a decade, but will the hardware last that long? And what happens when it needs a repair? You may be out of luck or out a lot of money, but Fairphone prioritizes the self-repair experience.

Old cameras are a fantastic way to experiment with photography, and outside a few brands, they can be an inexpensive way too. It’s easy to find older cameras in a broken condition for  a lot less money, but if you’re tempted to fix one then [enthdegree] has some advice for you.

It’s ostensibly a set of notes on the disassembly and repair of a Nikon F100 35mm film SLR, but along the way it’s full of useful tips and tricks for camera disassembly. he materials you’ll need, advice on not losing screws is one, and warnings against disassembling too much is another. It’s all the stuff he wished he’d known before starting, and now you can know it too.

Fixing up old cameras in this way is rewarding, and something we’ve certainly been known to do ourselves. But it’s worth bearing in mind that it’s not for the faint-hearted, and with decades of old film cameras sitting unused, often a working example might make more sense.
