Open Hardware

Open Hardware (OSHW) refers to physical artefacts whose design has been released so that anyone can study, modify, manufacture, and sell devices built on it. Schematics, mechanical drawings, PCB layouts, bills of materials, and any firmware or HDL needed to reproduce the device are published under an open licence — the physical-object analogue of free and open-source software.

The movement formalised around 2010 with the Open Source Hardware Association (OSHWA) and the OSHW Definition, but the practice ran ahead of the name. Arduino (2005) became the canonical microcontroller platform, RepRap (2005) demonstrated a self-replicating 3D printer, and CERN's Open Hardware Repository (2009) brought scientific-instrumentation hardware under the same model. Open hardware imports the free-software argument — that source availability changes the relationship between user and tool — and applies it to objects that must also be physically manufactured.

For the parallel society, open hardware is the substrate beneath distributed manufacturing, hackerspaces, and the DIY-biology scene — communities that can read their tools, repair them, and fork them rather than wait for a vendor. It connects directly to appropriate technology and the convivial-tools argument. The structural tension is that hardware requires capital and supply chains that software does not, so an "open" design can still depend on a single fab or component vendor. Closing that gap is the work of technological sovereignty.
