no doubt some of you are already quite familiar with these--they might even be a staple in your community already--but for those of you who have not heard of repair cafes before, here's a concept of how the most organized ones work:
Repair Cafés are free meeting places and they’re all about repairing things (together). In the place where a Repair Café is located, you’ll find tools and materials to help you make any repairs you need. On clothes, furniture, electrical appliances, bicycles, crockery, appliances, toys, et cetera. You’ll also find expert volunteers, with repair skills in all kinds of fields.
Visitors bring their broken items from home. Together with the specialists they start making their repairs in the Repair Café. It’s an ongoing learning process. If you have nothing to repair, you can enjoy a cup of tea or coffee. Or you can lend a hand with someone else’s repair job. You can also get inspired at the reading table – by leafing through books on repairs and DIY.
the most "formally" organized of these are also frequently affiliated with Repair Café International Foundation, a foundation which exists to promote and advance the concept (they also collaborate with iFixit to produce repair guides). affiliated ones are also very common in Europe, which isn't surprising since the Foundation is based out of Amsterdam. on non-European continents, these are less frequent and mostly found in larger cities (the site keeps a list with contact information if you'd like to get in touch with one). if you're in a larger city and looking for a quick and simple way to get involved in something or volunteer a repair skill, you might be able to just check out one near you. if you want to start one affiliated with the Foundation i believe they have a whole kit and process for that detailed on the site.
but the idea of "organizing a space where people can come and get things fixed, help fix things, and learn how to fix things" is also a simple one that transcends any one group and can probably be organized just about anywhere. you don't have to be affiliated with anyone to make that happen, you just need the people, the tools, and a good scope of what you can offer between those two things. if you and a friend think you can offer literally any kind of basic repair--however humble--to people in your community, however large or small? that's a good seed to start something like this from.
it probably depends on the repair cafe and the person organizing since how these manifest can vary a lot. i'd guess for most of them the spaces are public or at least open access in some way that doesn't involve renting--the one near me is done in a library for example, and with the coordination of the library.
