Right to repair 2021

A lot of people are asking for the right to repair. Many people believe products should last longer, and therefore when broken, they should be repaired. This requires products to be designed for repair as well as support for repairers of all kinds. The goal of right-to-repair rules, advocates say, is to require companies to make their parts, tools and information available to consumers and repair shops in order to keep devices from ending up in the scrap heap. The surge in interest in right to repair is good news for consumers and environment, but it isn’t great news for those companies keen on planned obsolescence.

Fix, or Toss? The ‘Right to Repair’ Movement Gains Ground article says that in USA both Republicans and Democrats are pursuing laws to make it easier for people to fix cellphones, cars, even hospital ventilators. In Europe, the movement is further along.

Vice article The Right to Repair Movement Is Poised to Explode in 2021 article says that in USA fourteen states are exploring “right to repair” legislation as the movement gains steam. Whether it’s John Deere’s efforts to make tractor repair costly and annoying, Apple’s bullying of independent repair shops, or Sony and Microsoft’s attempt to monopolize game console repair, US corporations have done an incredible job the last few years driving bipartisan public interest in the “right to repair” movement. Last year witnessed monumental progress for right to repair and 2021 is expected to take the effort to an entirely new level.

In addition to the environmental impact of slowing the rate of expanding landfills there are also other benefits. A recent report by US PIRG found that repair monopolization comes with significant costs for American consumers. It also found that American families would save $40 billion ($330 per family) per year if they repaired more products and used them for longer periods. That’s of course

The French repair index: challenges and opportunities article tells that since January 1st 2021, France is the first country in Europe to have implemented a repairability index on 5 categories of electronic devices. While this index is a key milestone for the Right to Repair in Europe, it isn’t without limitations.

    Howto repair switch mode power supplies #1: basics, and block diagram of a PSU

    The repair of switch mode power supplies (SMPS) is economically a good investment for electronics repair shops and for hobbyists. However, in contrast to the old low frequency transformers and linear power supply units (PSUs), SMPS are rather complex. Still, due to their low weight, high efficiency, and being able to provide stable voltage output, they have became an ubiquitous component in almost every electronic equipment.

    Kyle Wiens / iFixit News:
    A teardown of the iPhone 14 Pro Max shows the new X65 satellite modem and a similar internal design to the 13 Pro Max, making the device difficult to repair — The iPhone Pro Max 14 is out, and the general consensus among tech reviewers seems to be that it’s better than the last one …

    Apple’s 14 Pro Max is Worse than the Vanilla 14

    The iPhone Pro Max 14 is out, and the general consensus among tech reviewers seems to be that it’s better than the last one, but maybe not enough to justify an immediate upgrade.

    The satellite capability of this phone might come in handy if you are going to get stranded in the desert or on a Dynamic Island anytime soon—but only as long as the phone doesn’t break. Unlike the Vanilla 14, which made a big repairability step forward, this year’s Pro and Pro Max phones are trapped in the past with Apple’s less repairable legacy iPhone architecture.

    A Different Kind of Space

    With the brains out, we can move on to checking out what was once the SIM reader and is now, well, a whole lot of nothing.

    Of course, the US phone is the only model with this empty space—you can see an EU-sourced board with a SIM socket in contrast with a SIM-less US board. It’s still a little eerie and very un-Apple-like to waste space like this. The plastic spacer is roughly the same size as a 2×2 Lego brick and weighs half a gram.

    The question is, what will they fill the space with next time? There is zero chance this is staying empty for long.

    Enter the X65 Satellite Communicator

    Apple has switched to Qualcomm’s latest 5G modem across their product line. This is surely frustrating to Apple’s silicon team, who have been working for years (first with Intel, and then with their newly acquired in-house team) to produce their own 5G modem. They haven’t succeeded, so Qualcomm gets the win with their probably-very-expensive 4 nanometer part. The upside for Apple is that the new X65 supports band 53, Globalstar’s 2.4 GHz frequency for satellite communications. Try as we might, we couldn’t identify the satellite antenna inside the phone. (We have a guess, but tip us if you know where it’s at!) The iPhone already has 2.4 GHz antennas for Wi-Fi, of course—so Apple could simply be using the existing antennas.

    In a conversation with Reuters over the weekend, Apple was defensive about having their innovation layered on top of Qualcomm: “iPhone 14 includes custom radio frequency components, and new software designed entirely by Apple, that together enable Emergency SOS via satellite on new iPhone 14 models.” All right, we get it. You worked hard to put the whole thing together. But Samsung has good engineers, so what’s stopping them from fast-following with their own SOS feature? Well, Apple’s committed to buying 85% of Globalstar’s volume, so for one thing, Samsung would need another satellite partner.

    SpaceX and T-Mobile made an announcement, conveniently timed right before Apple’s Event, that they’d formed a technology partnership. Their media event, which looked rushed even by Elon Musk standards, promised SMS connectivity anywhere in the world. That would be distinctly revolutionary—but first SpaceX needs to finish Starship and launch a whole new constellation of Starlink 2 satellites each with whopping 7 meter antennas. It’s safe to say that Apple and Globalstar have the first mover advantage here.


    Only one question remains: What’s the score? Well, unfortunately these Pro models have been left in the dust by the more “boring” iPhone 14’s secretly enhanced repairability. Due to the 14 Pro and Pro Max continuing with iPhone 13-era construction, their score is stuck in the past, too.

    At 6 out of 10 these Pros aren’t terrible, but you’ll want to use a case to protect that expensive rear glass. We’re maintaining the same scores as the 13 Pro models, but with the newfound certainty that Apple knows how to do better.

    We are proud to announce that our service manuals for the iPhone 14, 14 Pro, and 14 Pro Max are online featuring replacement instructions for everything from the screen to the battery.

    How clever mechanics keep 50-year-old BART trains running: Windows 98, eBay, and scraps
    Half a century later, resourceful BART mechanics keep trains alive

    When BART first carried passengers, the country was sending astronauts to the moon. The Apollo-era trains were symbols of a generation barreling toward a space-age future complete with carpeted floors and a seat promised to every passenger.

    That was 1972, when BART was state of the art. But half a century later, as the agency celebrates its 50th anniversary this month, many of those same silver-and-blue trains are still chugging through the Bay Area. And keeping them running — even in the country’s technology capital — requires a special breed of ingenuity.

    BART mechanics rely on Frankensteined laptops operating with Windows 98, train yard scraps and vintage microchips to keep Bay Area commuters on the rails.

    Epoxy Blob Excised Out Of Broken Multimeter, Replaced With A QFP

    The black blobs on cheap PCBs haunt those of us with a habit of taking things apart when they fail. There’s no part number to look up, no pinout to probe, and if magic smoke is released from the epoxy-buried silicon, the entire PCB is toast. That’s why it matters that [Throbscottle] shared his journey of repairing a vintage multimeter whose epoxy-covered single-chip-multimeter ICL7106 heart developed an internal reference fault. When a multimeter’s internal voltage reference goes, the meter naturally becomes useless. Cheaper multimeters, we bin, but this one arguably was worth reviving.

    Throbscottle] doesn’t just show what he accomplished, he also demonstrates exactly how he went through the process, in a way that we can learn to repeat it if ever needed. Instructions on removing the epoxy coating, isolating IC pins from shorting to newly uncovered tracks, matching pinouts between the COB (Chip On Board, the epoxy-covered silicon) and the QFP packages, carefully attaching wires to the board from the QFP’s legs, then checking the connections – he went out of his way to make the trick of this repair accessible to us. The Instructables UI doesn’t make it obvious, but there’s a large number of high-quality pictures for each step, too.
