Homebuilt machines are machines built outside of specialised workshops or factories. This can include different things such as kit cars or homebuilt computers, but normally it pertains to homebuilt aircraft, also known as amateur-built aircraft or kit planes. Homebuilt aircraft or kit cars are constructed by amateurs. Homebuilt computers have been built at home for a long time, starting with the Victorian era pioneer Charles Babbage in the 1820s.
