\subsection{Hardware} Due to the recurring questions in the environment of the Hackerspace Innsbruck about the internal workings of a computer system and the lack of material to demonstrate these, hardware should be developed for educational purposes. This hardware should not be too complex to understand but still demonstrate basic tasks of a computer system. The targeted computing tasks are human interface device controllers, for which schematics and a working implementation in the hardware building style of the Hackerspace should be built. All nescessary hardware will be provided by the Hackerspace. If possible, already present hardware should be used, or, if impossible, new one will be ordered. All schematics should, where possible, be constructed in Free software such as Kicad or GNU-EDA. If possible, software-examples should be written as well, though the complexity of these is coupled to the time left to spend on the project. Software should be written in C, the coding convention is left to the implementer.
