A Californian start-up is seeking funding to make a computer that will cost $9 (£6) in its most basic form. Next Thing wants $50,000 to finish development of the credit-card sized Chip computer. The first versions will have a 1Ghz processor, 512MB of Ram and 4GB of onboard storage. The gadget, due to go on general release in early 2016, could become yet another rival to the popular Raspberry Pi barebones computer.
