Spectrum: A house in a year I might be able to do while growing my own food and perhaps making a few clothes to wear. I would have trouble building my computer from scratch without buying the motherboard, CPU, et cetera. If I did manage to build the computer, I would also have to build a wind or solar powered generator for the electricity. Maybe a hand cranked generator and a battery would provide enough power for a computer. Building a car from scratch is a big job. I do not htink I woudl even try. BTW: I never worked a lifetime for a house. I paid mine off in about 20 years and managed to spend my salary on various other things.
