\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, under which a \textbf{D}igital to \textbf{A}nalog 
\textbf{C}onverter\footnote{From now on reffered to simply as DAC} and a serial
console with TIA-/EIA-232 compliant voltage levels were chosen. For these
peripherials 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, 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 are coupled to the time left to spend on the project. Software should
be written in C, the coding convention is left to the implementer.
