    One time I had an ex ask me for some obscure cable that I happened to have. We went over to my cable drawer and as I pulled it out she said “Why do you have this drawer of random cables?”

    FOR THIS EXACT PURPOSE BECCA YOU BITCH

      I was a Scout as a teen. Taught me the value of being prepared and the use of good tools. Basically, I still carry things like a Swiss Army Knife, flashlight, that sort of thing. I also just like to have things in case I need them, like a charge cable or bicycle pump.

      You wouldn’t believe how often I’ve had interactions that go like this:

      “Does anyone have a knife? I need to cut this”

      “Here, use mine”

      “Why do you have a knife??? Who are you going to stab???”

      Same thing with other tools. People need one, you’re someone who carries it, now you’re somehow weird for being the only person prepared…

      I’ve had to guide people out of buildings during blackouts while using my flashlight (this was before phones had them). Number one comment while doing that? “Why do you have a flashlight???”

      MOTHERFUCKER, WHY DON’T YOU? On this planet, it gets predictably dark for, you know, almost half the day. So it might just be handy to carry some light with you. Tool use is what sets us humans apart from most animals, so can you at least try and not embarrass your species?

        “Why do you have a knife??? Who are you going to stab???”

        I’ve gotten this one too. I’ve had a knife on me almost every day for the last 15 years or so and I’ve managed not to stab anyone except maybe myself a little bit.

        Tool use is what sets us humans apart from most animals, so can you at least try and not embarrass your species?

        I’m stealing this.

        The Problem is, being unprepared worked out for them because they always had someone around who was prepared. It’s the same people who say afterwards: “You see, wasn’t that bad, all worked out fine”. Yes, it worked out fine because someone else was prepared and saved your ass. The worst of those people then also somehow turn it into their own achievement, which makes them think like that: “Why would someone carry around $thing$, I never do that and yet I still manage to save the day.”

        Unfortunately, being such a person seems to be a requirement to get hired for middle management.

          Step 1: Say “I have it for situations like this.”

          Step 2: Adamantly refuse to let them use it. If it’s something that has to get done tell them to get the fuck out of the way and do it yourself.

        It’s so annoying. I stopped carrying a knife regularly not because I stopped thinking it was a useful tool to always have but because while the law here does allow carried knives to be defined as tools, if you bring them in to certain places, they automatically get considered weapons and carrying any weapon is illegal (in most circumstances). So if I happen to go to a bar and have my knife in my pocket, it could result in a possession of an illegal weapon charge.

        I hate laws that assume intents based on triggers that aren’t necessarily associated with those assumed intents, like “carrying a weapon implies intent to hurt/kill someone”, “having possession of your keys anywhere near your car while drunk implies intent to drive drunk (even if you’re sleeping in the back seat)”, or “carrying more than some arbitrary amount of drugs implies intent to sell”, like anyone who shops at Costco intends to open up their own store. Lazy fucking laws.

          Don’t get me started on how stupid knife laws are in general.

          Here in the Netherlands, thankfully there aren’t many restrictions. You can basically carry 95 percent of common knives on you. Locking folders, fixed blades, generally legal unless expressly probhibited.

          We can’t own or carry certain types like gravity knives and butterfly knives. Why? “Because… well, fuck you, because we say so.”

          If I hop across the border to Germany, knife laws are more restrictive. Can’t have any form of locking knife, so that takes out most folders you’d want to carry. And if I went to other countries, they too have different laws. In France, you can own an OTF for example. And in the US, laws vary from state to state.

          Now, what does all that tell us? That knife laws are inherently made up bullshit by politicians and lawmakers who have NO FUCKING CLUE what they’re doing. Because if knife laws made sense, we’d have a fairly consistent set of them. And they tend to ignore that most actual knife crime happens with cheapo kitchen or utility knives. Nobody’s getting stabbed with a 500 euro safe queen.

          The knife is one of mankind’s oldest tools. It should be legal to carry everywhere and every form. Knives don’t stab people, people stab people.

            Yeah, the way I see it is those easy to deploy knives are most useful if you’re being ambushed. If you’re planning an ambush or attack, you’ll have plenty of time to get your weapon ready. Also, if you’re planning an attack, you’re probably not concerned with following the laws at all. You know, the whole “if you outlaw x, only outlaws will have x”.

            I’m curious what the line of thought behind no locking blades at all in Germany is. Also curious if they banned carrying fighting whips/crops in the century since Hitler did that as a hobby (which I’d consider almost purely an offensive weapon since they are more likely to just piss off an attacker if used defensively, unless they are one of those bullies that flees at the first sign of resistance).

              With regards to locking knives: most people would say that a locking blade is ‘safer’ to use and more capable of stabbing someone than say, a Swiss army knife, which would fold on your hand if you tried stabbing with it. But in regards to the actual laws that countries write and enforce, there’s usually not even a reason listed for such a prohibition in places that have such bans.

              For Germany, section 42A of the Weapons Act applies. That basically states (official english translation):

              It shall be prohibited to carry (…) knives with a blade which can be fixed with one hand (one-hand knives) or fixed knives with a blade length of over 12 cm.

              The original German for ‘blade which can be fixed’ (feststellbarer Klinge) is what we would refer to as a locking blade. It doesn’t even attempt to give a reason as to why.

              In the UK, where a knife with a locking mechanism is illegal as well, the Lancashire Police says only this:

              A lock knife is not a folding pocket knife and therefore it is an offence to carry around such a knife regardless of the length of the blade, if you do not have good reason. A lock knife has blades that can be locked and refolded only by pressing a button. A lock knife has a mechanism which locks the blade in position when fully extended, the blade cannot be closed without that mechanism being released. A lock knife is not an offensive weapon per se, as these knives were made with a specific purpose in mind were not intended as a weapon. However, possession of a lock knife in a public place without good reason is an offence.

              So this has a lot of contradictions in it. That first sentence makes no sense: ‘a lock knife is not a folding pocket knife’, when clearly there are knives, with locks, that fold. ‘A lock knife has blades that can be locked and refolded only by pressing a button’. OK, so a button lock is illegal. Which means a liner lock is OK, right? But no. ‘A lock knife has a mechanism which locks the blade in position when fully extended’. So now we’ve abandoned that button, and have moved on to mechanism… And then we get some form of argument as to why this all is banned: ‘A lock knife is not an offensive weapon per se, as these knives were made with a specific purpose in mind were not intended as a weapon. However, possession of a lock knife in a public place without good reason is an offence.’

              So there’s a ‘not offensive weapon per se’, but also ‘posession with no good reason is an offence’

              Basically, the only thing you can reasonably have on you is a non-locking small Swiss army knife. Anything that even hints at a lock? That’s a crime. Why? Fuck you, because we say so.

          I always carry a 5.11 backpack. So thankfully I don’t need to carry everything on my belt. The only stuff on my person are my wallet, keys and phone. Keys have a Victorinox Super Tinker on them.

          The rest of it is in the backpack. I always carry that thing anyway for shopping, to carry a camera, holds my rain jacket that sort of thing. And it’s a TARDIS / magic box in terms of whatever else might be in there.

          Some think it’s weird to carry an actual backpack, but I love it. Literally feel naked without it.

    There’s a tool sharing program in my neighborhood. You pay like $20 a year for access, and come by, borrow a tool/leave a tool. It’s great as people leave lots of big tools sitting around doing nothing.

    I want that for computer parts and wires.

    I refactor the box every year because there are usually some new cables.

    Some simple empirical rules:

    • keep the shorter cables
    • maximum of 3 cables of the same type: for donating, for lending, for spare
    • USB cables that can transfer data > USB cables that don’t transfer data
    • no damaged cables
    • store long cables as coils (tied up tight)
    • store short cables in bunches (tied up tight)
    • should be sorted and grouped into categories
    • box should be sealed, but aired out once in a while (outgassing)

          I’ve got a USB-c cable that can charge and transfer data at high speeds… But ask it to transfer display data to a screen and it won’t do a thing.

          The USB-c standard is a nightmare… While having the same port for everything sounds like a decent idea to reduce waste, not every product requires the full spec. Maybe mandatory labeling (like some companies are doing already) would be a solution, but it’s rather late to start with that now.

          USB A to C maybe, but C to C cannot work without data. To me MicroUSB was notorious for that. At this point all my micro USB cables that I have left don’t do data because I’ve given away, or worn out/broke all the ones that did data.

          Now I just have a bunch of USB C to ___ adapters. Right now on my desk I have a USB C to Micro, Micro to USB C (just in case) and a USB C to lightning adapter all stuck together.

      Voltage fluctuates. You could put 9v into it and it will be just fine. Hell you can probably put 12v into it and it will be fine. I have a switch at work that only exists to split one ethernet cable into two, and it’s rated for either 5 or 9v, but I’m using a 12v power supply on it and it’s just fine because it’s power conversion is rated for well over that (I think 16v max).

      Disclaimer: don’t blindly put higher voltage into a device rated for a much lower voltage. 9v devices will usually tolerate 12v, but not all.

            Honestly, I kind of wish crypto hadn’t gone to shit with the whole speculation thing… It was just this fun thing where obscure websites would let you buy random shit for laughs sometimes. Then suddenly investors had to try making money off something with no inherent value and ruined it :/

    Last move, I collected all cables in a one HUGE box.

    After the majority of the unpacking (like I’ll ever finish that) was completed, I sat down with the box and sorted out all the cables.

    I kept a sane amount of each cable, at least one and trashed the rest.

    I now have half a dozen labeled sterelite dollar store organizers with the cables in them.

    add it to your bucket list…

      I organized all my cables into like types and put them in gallon sized plastic bags to prevent all that intertangling, at least nominally. I still hardly go into that box though. It’s still a pain in the ass, just less of one.

        LPT: intertangeling only happens when cables are looped. Just put them together linke you would crumble a piece of paper and put them in your bottles. No more intertangeling

    It’s true. That box has the utility of the highest utility cable in it. Which means it’s a lot. Worth taking up space under a bed you aren’t using. Anti-horder culture goes too far. It’s more complicated than dogmatically throwing away everything or keeping everything. Don’t throw away things with real utility. Civilization is built on accumulated utility in durable goods.

      Also, if you tell yourself “I’ll just buy a new one if it breaks”, take note that the quality of whatever new thing you buy will be worse than the current one you have due to decades of companies skimping on quality to remain profitable.

    After switching to solar DC and batteries I suddenly cared a lot more about ac/dc power inverters needlessly wasting my limited energy supply.

    Slowly I figured out how to power my devices without ac outlets. Mercifully 5v,9v,12v,19v at 1-5A are pretty standard values for most lower powered DC appliances.

    A good DC barrel plug 5.5mm universal adapter kit, a usbc-PD adapter cable with manually selectable voltage levels to 5.5mm barrel plug, and a car plug to dc barrel plug universal adapter kit have taken good care of 95% of my adapter woes.

    It feels sooo good to figure out how to power something directly with USBC and see the wattage drawn get cut down significantly.

    Whats my point? If people knew a little bit more about the finer details of power supplies and dc barrel plugs most of their box of junk cables could be phased out with confidence. If you have 20 year old electronics with some weird incredibly specific voltage and barrel plug I would heavily consider just getting a new version that runs on usbc-pd or a more standard power rating. And if I ever need an old video cable? You’d better believe amazon and eBay still got it.

        I am off-grid for much of the time so I rely on an entirely DC to DC system. 200 watts of solar panels power up my batteries which supply 12V at a capacity of about 400 watt hours. So for many appliances like laptops and speakers and computer screens which use DC power it makes sense to try to convert the voltages directly though other means than the typical AC to DC power plug supplies that you usually use in homes. Doing this I can cut down total power consumption for each device down by about half which is really important for conserving power on a limited energy supply.

        In a theoretical scenario you could totally run a seperate voltage line for DC energy through a house, though this has several complications. The main drawback of DC energy is that the lower the voltage the more resistance losses you get running power through a foot of cable. So the cable losses would become signifigant after running 200 feet of cable probably less even. You could bump up the voltage to 48VDC for longer stretches of wire and to power high end RV appliances but now were loosing some of the safety that comes from a lower voltage DC system. Im not familiar with commercial solar installations in homes but I think its easier and more economical to eat inverter losses and use the batteries to supply AC power using preexisting wiring. If you were building a offgrid home its a design thing to consider, reducing and centralizing wiring and appliances.

          But then what are you doing? Are you connecting your laptop directly to the battery with shorter cables?

            I have my portable folding 200w solar panels on the ground and run about 20ft of weatherproof cabling running along the ground through a small inlet hole into my residence. They connect to my battery system which is located in a good central spot for all my electrical stuff to comfortably reach. Everything I own that runs on electrical power that cant be powered with portable rechargable battery banks is located in the same room as my batteries.

            I can deliver DC power through car plug ports, USBC-PD 100W and regular usb A outlets. The 600w AC inverter is useful for brewing cups of coffee, running fans, and turning on a desktop pc for advanced GPU workload stuff. Its important to keep that ac inverter off most of the time especially at night so prefer using car plug adapters and USBC-PD to directly power most of my DC appliances with variable voltages instead. From the car plugs and usbc-pd charger ports, I run my dc appliance cords to my devices which are usually 6-10 ft long. My laptop is usually powered up through a car port travel adapter but I can also use USBC-PD and an adapter bit if the car ports are all taken up.

            Thank you for showing interest if you want to know anything else ill be happy to explain. lowtechmagazine’s “Slow Electricity: The Return of DC Power” is a great read on the subject the info has been very useful for my purposes. They cover residential dc wiring like we are talking about and its located around the end of the article in the ‘How To Limit Cable Losses’ section.

      Are you suggesting that modern USBC power supplies don’t have that parasitic draw that other DC power packs have?

        They have solar + batteries, so they have to convert the sun into DC, hopefully directly supply that DC to their batteries, then convert that DC to AC power, then convert that AC power back to DC. Converting AC to DC or vise versa is a reasonably lossy process, so not doing double the conversion is even better.

        Also some less than ideal setups convert solar directly to AC, so in order to charge your batteries you have to convert it back to DC.

        Thanks, glad to have inspired you! The other person who replied is spot on. I have an entirely DC system so my main advantage comes from cutting out pointless double-conversion from dc to ac back to dc again. Powering on an DC to AC inverter is a parasitic draw that consumes enough power to eat through a good amount of battery capacity if left on by itself. Then using that AC inverter just to power another inverter to step back to DC introduces even more losses and parasitic load. So, its worth my time to try figuring out ways to directly power devices by directly converting DC to DC voltages and cut those needless loads out greatly boosting total efficiency.

        USBC-PD technology is an incredibly useful innovation for direct variable dc to dc voltage supply. Specifically a 100 watt usbc-pd charger can supply 5v,9v, 15v, 20v at up to 5 amps (5Ax20V=100 watts). A car cigarette plug can supply 12V at 10A or 120 watts of power. Together they can directly power a great many household DC appliances off of batteries powering a DC to DC inverter.

        For some examples:

        A 24" lcd computer monitor at full brightness consumed 50Wh through AC inverter. It was brought down to 25Wh running through DC inverter. On half brightness it consumed 15Wh and 10Wh at minimum brightness.

        A thinkpad laptop full brightness was 25wh idle -50wh full load, then brought down to 12-20wh.

        My nintendo switch game console docked into the lcd screen consumed about 15-20Wh with inverter, brought down to 10Wh.

        Desktop dry herb vaporizer (Arizer Extreme Q): 80Wh heating up, 30-50wh idle brought down to 50Wh heating up 15-25Wh idle.

        Electric blankets. During the cold months using my electical energy to help keep warm is very important to me. But I cannot keep a regular house electric blanket on for more than an hour or two. I could not keep a car plug blanket on overnight at 80wh. I could keep on a USB powered blanket on overnight at 10-15Wh. And you know what suprised me most? It was damn warm, when I figured out the right way to sleep with it. Have to sleep on it as a matress warmer and layer some heavy blankets on top and let it warm up for an hour or two. But it works and works well. The USB blanket doubles as wearable poncho too which is nice. I wish a USBC-PD one existed with variable wattages.

        So as you can see each time I macguyver a way to directly power these devices the total power usage is cut by almost half per device. To someone else who can afford an array of solar panels and a massive bank of batteries they can get away with not caring about saving 20Wh here or 15Wh there. I have a very modest system of 200watts solar feeding into ~400Wh battery capacity total so these savings mean the difference between my batteries being dead overnight and having lots of spare juice left over to brew a cup of coffee with those AC inverters when I wake up.

        Of all these devices listed, the LCD monitor is one that has a noticable parasitic load even when the screen is off it consumes a noticable amount of power at idle. The way I would deal with most instances of parasitic draw like this is to find a product throws a physical switch to manually cut contacts with the DC-DC inverter when not being used. In this case a car plug extention cable with a knife switch built in would work great.

          Okay so the magic sauce here is USBC-PD which is some type DC-DC voltage converter. Then it’s just a matter of barrel connector roulette to find the appropriate plug for each device.

          I live part time out of an RV semi-off grid for some of the year and the “using AC/DC power packs off an inverter” always struck me as super dumb which your data basically confirms.

          What you’ve given me is a roadmap to figure this out without having to reinvent the wheel.

            You got it man, right on. I would like to give you some more information about the usbc-pd stuff and some of the things I figured out with it. So here is a link to the farsense usbc-pd to standard DC 5.5x2.5 adapter with manually selectable voltage based on button press. This cable is the most important part and I will explain why its so important. USBC-PD essentially requires three things to work right.

            The first thing is a charger(the DC to DC inverter in our context) ideally rated at either 65w or 100w as both of those support up to 20v the difference being 65W can only go up to like 3.25 amps or something like that. The simplest and cheapest dc to dc chargers are usbc-pd car plug chargers which convert the 12v from a car battery to the required voltages. The anker one I just linked is a little pricy you can find them for cheaper but it seems good quality and I like the cable I bought from them.

            Speaking of, the second thing you need is a USBC-PD power cable that specifically supports the same wattage your charger outputs. Not all of them are rated the same you gotta use a specifically rated cable that handles higher voltages. If you use a 100W charger gotta get a 100W cable. I’ve had good luck with this anker one

            The third and most crucial thing to understand for our purposes, is that you need a communication chip on the appliance side that tells the charger/inverter what voltage to send. The nice thing about that farsense manual voltage selector cable is that it has that communication chip built in with all the different voltages to pick from. Thats the real secret sauce of this setup. That cable and its ability to choose voltage levels is the heart of it. All thats left is to track down the specific dc 5.5x2.5 to X adapter bit and select the proper voltage on the cable and its good to go.

            There are USBC-PD adapter bits that have this chip built in for a specific voltage, commonly for laptops at 19-20v. If you manage to track down the proper usbc-pd to barrel plug adapter at your specific needed voltage it will cut out having to manually set the voltage each time you plug it in compared to the farsense cable. But it may be hard tracking down such a specific adapter bit.
