  • Time to DIY!

    Waveshare touchscreen for pi, 1200x800 is a good price and for home assistant that is fine. $70/75 for 8inch/10.1inch version. (10.1DP-CAPLCD)

    Raspberry pi 3/4/5 can mount directly on the back of it. For whatever outrageous price Pis are now. (Around here, a 4B/4GB is 60€.

    Wave share PoE hat for $20

    Assemble it like Lego, put it in a wooden frame or 3D print, done. Around 160 USD plus shipping for a full build of a POE battery-less touchscreen display that runs full Linux of whatever flavor. (And is quite overkill as far as power).

    You could probably do it even cheaper with an orange pi zero 3 with a PoE to USB-C converter or a Banana Pi BPI-P2 Pro IoT which has PoE built in.

    It is cheaper than a tablet and strips out the useless things like a battery, camera, really high DPI display, LTE radios, etc… For a simple home assistant kiosk.

    But yeah, epaper displays are 3x the display cost without touchscreen. Though in my opinion, epaper is better for static non-interactive sensor display which can run on battery with an MCU for almost no power because it only has to update once an hour or so.






  • Hey, something I can maybe help with.

    Flatpak IDEs on the main system are not very useful for development. I got rid of mine entirely. I am developing firmware so it might be a bit different from your case, but what I did in have a single arch distrobox where I could install everything embedded-dev-related that had to work together (JLink, nordic tools, code-oss, etc…) on that. Then a few standalone debugging tools like STLink and Saelae logic2 could be installed to the home folder by default and Code could still find them from the distrobox (but they could be installed in the distrobox also). It doesn’t even need to have an init system, but I ran into a few problems like having to manually chmod usb devices to give STLink access. Udev rules are also hit or miss in /etc/udev/rules.d, e.g. the STM udev rules just don’t work, but nordic does.

    High storage consumption is likely negligible (or at least nitpicky) since storage is so cheap nowadays. Your SSD doesn’t care if it has 15GB or 20GB of system programs, especially when development codebases and SDKs, games, and media will likely make up 90% of space and almost never share libraries even on traditional systems.




  • It is funny because electric motors have nearly unlimited* torque depending on the kind. If you have thick enough power cables and winding conductors, you can just keep pushing it harder to get more torque.

    It is like the thing they are very good at, besides sound levels, double or triple the efficiency, low/no maintenance, simpler with less parts, no emissions, etc…

    Literally the only good thing about combustion engines are their fuel source energy density.

    I think the problem is that motorheads see the enshittification of the auto industry as a whole and just say it’s because of electric motors because it happened right about the same time as EVs started coming out and try to push back on the wrong thing.


  • I was not earning enough to donate with our renovation to try to fund, then I was also unemployed for a period, but now I have a new job that pays around 300€ more net per month, so I think I can start donating and still pay for the house and renovation.

    • FreeCAD
    • KiCAD
    • immich
    • gadgetbridge
    • codeberg
    • KDE
    • Krita

    Some projects that I use a lot don’t want donations (jellyfin, antennapod, HomeAssistant, etc…) though



  • While the lack of laughter can be from depression or stress (the podcasts I used to die laughing from only get an actual laugh out loud moment every once in a while now), I feel like most story-based video games that do humor try too hard nowadays and it doesn’t land (like outer worlds)

    Most of my laughter in video games, personally has been from interacting with other people. Valheim, Helldivers 2, REPO, overcooked, stardew valley, etc…

    Probably the last single player game I laughed with was A Hat in Time or something.


  • But on this threat model? Why would it not be good?

    It has to physically accessed on the PCB itself from what I gather.

    There are 2 “threats” from what I see:

    • someone at the distribution facility pops it open and has the know how to install malware on it (very very unlikely)

    • someone breaks into your home unnoticed and has the time to carefully take apart your vacuum and upload pre-prepared malware instead of just sticking an IP camera somewhere. If this actually happens, the owner has much much bigger problems and the vacuum is the least of their worries.

    The homeowner is the other person that can access it and it is a big feature in that case.
