A modular laptop built with a Raspberry Pi. An ergonomic, programmable, mechanical keyboard made from slabs of maple, so it looks like a solid-state electric guitar. A device that plugs into a wall socket that allows you to control devices from your smart phone.

The convergence of these two trends is creating an outburst of mini-entrepreneurship unlike anything ever seen before. In doing so, they are making open hardware -- the long-discussed, seldom seen cousin to open source software -- a reality.
