    Let’s see:

    • Back in 2007 or 2008 I attempted to create a CPU architecture that directly uses Brainfuck as its instruction set. I had to put it on hold before it was completed because I had a custom FPGA development board with really bad documentation but if I ever get my hands on an affordable FPGA, it will get done eventually.
    • I’ve created a nonogram that solves to a rickroll QR code. I had to rely on the error correction because the exact pattern didn’t result in a well-defined solution but I’ve recently learned about some more parameters that you can tweak on a QR code. So now I just need to acquire or more likely build a QR code generator that lets me manually control those parameters and an automatic nonogram solver so I don’t have to manually solve a bunch of 25x25 nonograms to confirm they have a single solution.
    • My plan for tonight is to start porting a 22-year-old handheld game to a ~35-year-old home console. I’ve acquired a C compiler but will probably have to learn assembly for a CPU architecture that was barely used for anything else. There is no chance to ever share the resulting game without getting sued to hell and back again.
    • I’ve made chainmail bikinis for a couple of friends.
    • Edit: One more because it might be my magnum opus. Have you ever played KJumpingCube? That doesn’t only work on grids but on arbitrary graphs. My friends and I chose a Risk board. Not a digital one. A real life physical Risk board with actual dice on every country that need to be turned by hand. A single game took us about 6-7 hours with the winning move alone taking up the last hour.

    That’s just what I comes to mind at the moment. I’m sure if I spend some time thinking or digging around old hard drives, I can find more.




  • That’s VGA, it’s gonna be fine. Most wires are either ground or not used for actual image data. R, G and B are analog so noise on those just makes the output noisy, no big deal. That leaves us with HSync and VSync. They are digital signals with 3.3V between on and off and only a single pulse per line / frame so they’re also pretty robust against noise.

    So unless you’re going for an extremely high resolution on a really cheap monitor over a long distance, the worst that will happen is that your image will look grainy like TV static. It would take quite a bit of interference before the sync signals degrade enough to not get any image at all.




  • Well, until you open a browser… or five, because these days nobody wants to build native applications anymore and instead they shove webapps into electron containers.

    Right now, my laptop doesn’t have to run much. Just a combination of KDE, browser, emails, music player, a couple of messengers and some background services. In total, that uses about 9.5 GB of RAM. 20 years ago we would have run the same workload with less than 1 GB.
