  • If you know not only what a torque wrench is, but how to use it properly you will likely have no trouble changing brake pads.

    The feeling I get is that auto work goes much much deeper though, and I am interested in resources that offer that knowledge.

    Full engine rebuilds, or even troubleshooting intermittent CANbus issues, sure. But basic maintenance like brake pads or changing out a failed alternator just require basic hand tools and some minor knowledge you can get from youtube.


  • Replacing brake pads (not shoes for drum brakes) is a fairly straight forward activity and possibly one of the best (besides perhaps changing engine oil) to perform yourself. Youtube is a great place to start. You can likely even find a full video of pad replacement for your exact model of car.

    What is your current knowledge with using basic hand tools such as screwdrivers, hammers, and wrenches (for hex head fasteners)? Do you know how to replace a flat tire? There’s lots of overlap with that procedure and changing brake pads.





  • There’s a pronunciation guide in the original documentation, and that didn’t end the debate.

    Humans are even more horrible that this first glance suggests. Imagine, one day, the debate truly ends and a single pronunciation for GIF is universally established and recognized by everyone. A group of humans will start to intentionally mispronounce it (or misspell it) just for the aggravation it will generate in others or for their own amusement.

    This is where the meme-like behavior of deliberately misspelling the popular phrase (at the time) “all correct” as “oll korrect”. This was later abbreviated as “o.k.” and then eventually “ok”. A phrase we likely use dozens or hundreds of times a day is meme-speak from 1839. source


  • How much of the hardware and software you use must be registered, requires internet access to work, a proprietary app? You don’t actually own anything that fits in those categories and they can be taken away from you at the manufacturer’s whim.

    While there are certainly commercial versions of those that fall into those categories, there are many that don’t.

    • My 3D printer from Monoprice has a power plug and and SD card slot. No requirement to connect it to the internet at all for it to function.
    • Here are 7 FOSS CAD software packages that aren’t own by any company.
    • There are countless NFC and Wifi modules that don’t require a “call home” to the vendor that can’t be turned off. Cell modems may be a special case because you’re using a providers network.
    • There are lots of large format printers that, once the drivers are install, need zero network connections to operation. No vendor shutoff possible unless you allow it.
    • Same for CNC machine. Certainly at the high end industrial scale this may be different, but there are many of solutions for home and commercial users that don’t require an always-on connection.


  • Yes, you can definitely do all those things, but they’re far outside of the realm of a normal consumer, and unless you know, to look for those things. It’s a lot harder to find.

    I’m confused by your premise then. If you’re saying “Today’s consumer electronics can’t be tinkered because they require specialized knowledge.” I’d argue that was always the case. How much tinkering could be done to an Atari 2600 from 1977?

    How much tinkering would be done to a VHS VCR from 1989 without specialized knowledge?

    These are prime examples of prior generations of consumer electronics.


  • Thought of this the other day. I bet a lot of us are like this, because in today’s world a lot of things we used to tinker with are gone (electronics are made to be single use and unfixable, cars are proprietary and can rarely be modified or worked on without many many thousands of dollars now, etc).

    I feel the exact opposite. Today I can tinker in ways I never ever could before for two reasons:

    1. so many more technological solutions exist
    • 3D printing
    • CAD
    • wireless (near field, Wifi, and cell network)
    • large format printers for paper, vinyl, and fabric
    • CNC for wood and metal cutting
    1. components are so cheap relative to the past
    • single board computers (Arduino, ESP32, RaspberryPi, etc)
    • high quality optics and CCD cameras
    • mountains of cheap storage
    • small and large LCD displays, eink

    When I started out the cheapest computer was today’s equivalent of about $2000. To be able to buy a whole computer in a Raspberry Pi zero for $10 is insanely awesome! Electronic components from Radio Shack were few and very expensive. Test equipment like oscilloscopes were simply out-of-reach financially. Now I have a handheld one I bought for $200.

    This is an amazing time to be alive with tinkering!

    I’m not saying your proposal wouldn’t be beneficial, but it costs money (which is hard to come by in education anyway) and doesn’t increase learning outcomes. What educational item gets cut to pay for the whole staff of people that “identifying kids with ADHD”?

    This is the harsh reality that there are lots of good ideas, but only so much resources to implement any.


  • It’s been many years since I’ve been in a classroom, but I feel like we could and should have a highly advanced system for individualizing education in a way that works with most learning styles.

    I agree with your intent, but my point is underscored by the second to last sentence in your quoted text:

    " I can code those algorithms in a program, and put that program on a floppy disk, and then we can mass produce that disk. We can make millions of copies of that disk and spread it all over the world so that millions of people can play my game. "

    That person isn’t going to do that for free. They’ll likely expect payment (a reasonable ask) for the initial production, but also the ongoing support/update of the curriculum. All of those costs would be in addition to the resources spent on the lecture for the other student.



  • It honestly shocks me given the number of people who have these exact same experiences that we cant do a better job of recognizing and supporting people.

    I think its only a recent idea that people learn in different ways. Making a single curriculum is hard enough, making bespoke ones for each person tailored to their strengths and weaknesses requires far more resources than most educational systems have.
