- If you're in a country like France, where buying fans for your daughter's schools is not allowed [0], or installing your own store-bought AC unit either, making DIY devices seems the easy part, sadly.

by jiehong - I recall predecessors to this idea from the 1970s, which probably implies I heard about them from Futurist Magazine and/or the book Small is Beautiful. It has always been suggested that engineers could do something worthwhile by inventing very simple yet useful things that could realistically be made in poor/underresourced countries or villages.by CurtMonash

- I like the idea behind this. I feel like far too often, the solutions we build for poor communities involve specific materials that can't be manufactured locally, so it just creates more dependence rather than self-sufficiency.
It's one thing to build and ship 1000 bicycles to a poor village, but it's another to teach a village how to make bicycles with random spare pipes and materials they can find anywhere. That way if something breaks, they have the skillset to fix it.
If you go to villages in developing nations, you'll see these kinds of innovative solutions all over - things that don't seem like they should work but they just do after lots of trial and error.
by xmprt - Victor Papanek's Design for the Real World [0] is a foundational text in the area of Appropriate Technology (cited here by others).
Essential reading alongside the Illich (also linked by others), Pye's Nature and Art of Workmanship [1], and Winner's "Do Artifacts Have Politics?" [2] for those interested in.... Let's call it an ecology OF technology?
And also the Papanek was probably the book that felt most like a forbidden text in undergraduate architecture school...

- Ages ago, I had Vol. 2, _The Metal Lathe_ which was one of the 7 vol. "Gingery Books", a series on _Build Your Own Metal Working Shop from Scrap_ (Vol. 1 was _The Charcoal Foundry_) which used as its central conceit the fact that a lathe is the one tool in a machine shop suited to easily replicating itself (insert old machinist joke about how you can make anything with a shaper, except money).
Always regretted giving my original away, the typewritten text and hand-drawings had a certain charm which the updated single leatherbound hardcover lack.
The Gingery Book Store is shutting down this year, and not reprinting any books, so one wonders what will replace it:

Another effort along these lines was the "Multimachine" which attempted to create a metal-working equivalent to the woodworking shop's ShopSmith using an engine block, taking advantage of the fact that they are readily and inexpensively available from junked vehicles. I believe it was on the "Opensource Ecology" site linked elsethread.
Perhaps Chris Borge's series of machine tools made with 3D printed shells filled with concrete and arrayed with hardware store components?

That said, as various machinists have joked, I am still "shaper curious", and have been sketching up a hand-operated shaper --- debating on saving for a set of castings, making my own, or going the hardware store route....
