Ok, you're the "crazy chicken man", here's a crazy idea that's might be right up your alley. The tub and fingers are all made outta plastic, easy to fabricate, & that part don't rust or rot. The problem would be the electric motor........ So figure out a way to hook that sucker up to an old bicycle. The vertical power transmission from the bicycle would need to become horizontal, of course. But I was amazed at what Filipinos could do when I was there. You could then patent the whole mess.
Ok, back down to earth now..... Isn't it amazing how we never fix stuff anymore, we just toss it and buy new stuff. I have fixed more small electrical appliances by merely sticking in new brushes than I can remember. I've saved a ton of money doin' that. That's likely the only problem in your drop saw. Either that or a break in the electrical cord/wiring. A continuity tester (volt/ohm meter) has always been one of my "essential" tools.
But you're absolutely right, we are very much overdependent on "sophisticated technology". That's one of the things that makes what you're doing with the chickens, goats, quail, garden, water buffalo and all - so attractive. We feel as if we've lost something with our jet planes and computers.
indeed we have become a disposable society. complacency and compartmentalization have overtaken our lives.
for me, the computer has liberated me from that place. i have a PC in the living room and a laptop in my bedroom and I am always jumping on one or another. cloud drives like dropbox make my files accessable from anywhere so I can even pull them up on a phone or an internet cafe in a foreign land. i have never played anything more than a little poker on a pc. I do download the odd movie but most of the time i am reading new stuff.
so many of us here are constanly learing from each other here and the availability of information at our finger tips gives us resources humanity has never experiened.
while I have the luxury of helpers and employ the services of others with things like car repairs, there is nothing done or built that I dont have a good knowledge of and could really do myself if i had the time and dexterity.
