I often played with the thought of buying a fair phone, but in the end it’s just too expensive for me. I usually buy used devices for about 150€ from eBay and flash a custom ROM to get rid of google. If I can use that phone for 3 years I am happy. This way I am doing something for the environment and do not support mining of critical minerals in Congo etc.
But yeah, apart from Fair phone almost all devices are very, very hard to repair on purpose, and you need a lot of tools and a but of luck ;)

Happy cake day!

I just changed the USB port of my Motorola because it was broken AF. I always had to tweak around for 5 minutes to get the cable stable enough for loading, it sucked. I bought the spare part for 17,90€ on eBay. It was a struggle removing the back cover, but now I have a mobile for another 2 years!

When I left university, which is like 6 years ago, we used distilled water. As tap water does not usually have a pH of 7 but can vary between 6.5 and 9 (depending on location), it makes absolutely no sense for me to use it for rinsing. However this may depend on your device and application, as for household level like measuring plant water or something tap water could be sufficient.
