While FLOSS is still keeping artists and curators busy with ways that digital art can be produced and distributed in a connected society, a new artistic and conceptual challenge has recently surfaced: open source hardware. What is open about open source hardware? In much the same way as open licenses define the freedom of FLOSS software, open source hardware will need to be defined, and this definition needs to be developed further at an industrial and economic level. Many artists embraced FLOSS for political reasons, and are beginning to do the same now with open source hardware. But is it that simple? It is time to shed some light on the dark side of open source hardware.
