I got stuck down a rabbit hole checking out these two books, the author of Mini Technology is a wizard of appropriate tech and these two books tell how to make all manner of things useful to someone trying to be more self sufficient.
In his foreword he said that while people can make jets and such that does not negate the need for knowing how to make a wheelbarrow. This world will always need old tech.
That sentiment is exactly the same as my way of thinking.
I really enjoyed looking at his plans and reading about all the things he described in his book. If you enjoy this site at all you will probably love these two books
Mini Technology II
Nice! These will keep me busy for a while.
