I just need to get good at engineering, programming, welding, networking, marketing, and accounting. Then, I’ll buy a CNC machine, a 3D printer, and a month’s worth of raw materials. Add a set of screwdrivers, a bunch of power tools, and a workshop near where I live because long commutes make me sad, and I’ll be able to build a non-functioning prototype in about a month, lose my shit because it doesn’t work, and give up.
