DIY repairing
Nevertheless, when wondering whether some invaluable gadget is irretrievably broken or can be fixed, perhaps with some material or tool that I'd never known existed, it helps to find out whether it's fixable. If so, I keep the item and try to fix it in future, rather than throwing it out and replacing it.
The foremost organisation for repairing in the UK is the Restart Project, which invaluably lists all repair events (worldwide). I joined its online repair forum (the Restarters Community) which sends me occasional summaries of recent contributions if I don't visit the website often enough; some of those are really useful.
For instance, I knew about Restart's own Restarter wiki and the American site, iFixit, but there's also a French one with a slightly different focus: La Librairie. Since all are word-searchable (and an internet translator can help non-Francophones use that last one, if the others don't produce results), that increases my chances of not having to invent a means of fixing something. So try searching these if something breaks, do:
