    Didn’t someone do a test and an old wire hanger worked as well as an audio connector as an expensive wire?

    I would really appreciate it if nobody looked at the PS/2 to USB adapter currently on my workbench, kplzandthx.

            Yeah, not the best angle. The PS/2 port is that little silver box. The USB-C port is on the PCB. This was assembled to go inside a vintage keyboard to semi-permanently convert it, but I’ve been using it to test other boards. If a board is fully intact, I’ll just use an external converter, but there used to be a practice of snipping the cables on hardware that businesses retired for accounting purposes if they were written off, which can be a good, if risky, way to get an eBay buy for cheap.

      I may have recently retired my IBM->PS/2->USB daisy chain because I was gifted a modern mechanical keyboard…

        Well, I fell pretty deep into that rabbit hole, where I’ve even designed a couple of primitive circuit boards and hand-wired a bunch of keyboards. I also mess around with vintage stuff a bit.

        This particular converter is programmable and meant to be used with a not mechanical 122-key terminal keyboard made by the company that took over IBM’s US keyboard factory, but it’s been hanging out with several DuPont wires shoved into it to connect it to a molex connector to test a different old board.

    This reminds me of how my speakers work.

    I have a 3.5mm jack for my speakers that converts to an RCA jack at the end, I also have T-intersection that goes between an amplifier and the RCA jack to intercept the signal and send it BACK to a set of desktop speakers.

    Why? Bootleg surround sound, I know it’s just stereo, but hey, more speakers! Also it sounds better, and it can get louder.

    That’s not Zombo COM1:, that’s the serial port, the one above it. This is Zombo VGA.

      Ouch, I just assumed it was the serial port and didn’t even look how it’s reversed. There must be all kinds of fun things you can do by hand-writing VGA data.

        The VGA connector is actually reversible! Once. given enough force. It also doesn’t actually work properly when installed upside down.

          Well, by “reversed” I meant that the cable has pins, and the computer has slots, what is the inverse of serial. Not that it’s upside down.

          You can’t plug a serial cable in it and make it work, no matter how much force you apply. You can probably do the opposite, and plug a VGA cable on the serial port with the exact right amount of force, though.

      I mean VGA is good for 1080p 60fps which honestly is a plenty high resolution even today. Sure you can get higher resolution and you can get higher refresh rates, but for a ~20" panel 1080p/60 is a sweet spot and you can get some really good panels for pretty cheap these days at 1080p/60

    You should see some of the contraptions I’ve done (or had done) over the years. Like basically taking a a BGA FPGA off the board, soldering wires to the pads, and soldering the other ends to the balls of a different brand of FPGA to get something working while switching suppliers.

    I left the headlights on overnight and woke up to a dead battery.

    Stupidly left my tools in the house as it was an impromptu trip out of the city.

    So I wired the output on the solar charge connector to the permanent live on the head unit and left it for a while

    I am so conflicted about this meme; on the one hand I’m in awe at this bodge into the RCA port and on the other the caption made my eye twitch.

      Had a cat engine in a crane once. A pin got damaged fir the ecm. Cat said 5k + labour to replace ecm plug. I said fuck you and any one that may slightly resemble you my good man. Went back to yard. Wittled down and ramed a solid 14awg wire in the hole. Been fine for over 5 years now.
