  • That setup is probably perfectly adequate. You can configure the OS to set the MicroSD to read-only mode, which would decrease the chance of corruption to near zero. According to this page:

    Just run sudo raspi-config from the terminal then go into “Performance Options” and select “Enable/disable read-only file system”. You can do that again to enable writes if you ever need to change a config option or update the software.

    The glass transition temperature (the temperature where plastic starts to become malleable) of PETG is 85°C, so if you put a PETG spoon in boiling water, it would deform and become pretty useless. However, if you used a high temperature plastic with a glass transition point above 100°C, you might be able to get away with this method.

    Also, just to clarify, a dishwasher does not get to 100°C. You could use it to get the initial food off, but you would then need to boil the utensils manually on a stove to actually sterilize them.





  • That’s what I thought too, but this system doesn’t actually use salt water. It uses a membrane that’s filled with lithium bromide (a “salt” in the chemical sense of the word), which absorbs moisture from the air while the computer is off and then is able to slowly “sweat” the moisture away while the computer is running. They say it can run for about 6.5 hours before needing to be recharged.

    This is pretty cool for data centers which use massive amounts of power to keep everything cool, because it’s passive and doesn’t use any extra energy for fans or water pumps or anything. It really isn’t all that great for consumer PCs though, because it’s a lot easier to deal with waste heat.








  • Personally, I have a very old Kindle Fire mounted to the wall that I set to never go to sleep. Its still powerful enough to run a web browser to access the HA interface, so it’s a good use of tech that would otherwise be sitting in the obsolete pile. However, it is just powered with a USB cable hanging across the wall, so not super elegant.




  • Personally, I used TrueNAS Core (known as simply FreeNAS at the time) for my very first NAS setup knowing nothing about BSD-based systems, and it’s been pretty much fine. It has ZFS which is absolutely desirable for a NAS that you store important things on, and It has some quirks but Ive been able to accomplish everything I’ve wanted to with it just by looking up the miriad of guides available. Not saying it’s better than the alternatives, just sharing my personal experience.

    However, if you’ve already got OMV setup and it’s working for you so far, I would stick with it. I believe you could always import your drives into another NAS system if you decide to move later, so why fix what isn’t broken?
