Making Hardware with KiCad and Friends
|
||||||
|
|
||||||
|
KiCad is a well-established Open Source EDA suite that provides tools
|
||||||
|
for most of the basic tasks in circuit design. In larger projects,
|
||||||
|
and especially those of an open and collaborative nature, additional
|
||||||
|
requirements appear that KiCad can only partially satisfy.
|
||||||
|
|
||||||
|
Specifically, collaborative projects benefit from visualization that
|
||||||
|
helps to quickly follow the work of others and to track a project's
|
||||||
|
revision history. Furthermore, an automated and thus easily
|
||||||
|
reproducible workflow lowers the barrier of entry and avoids costly
|
||||||
|
mistakes.
|
||||||
|
|
||||||
|
In the Qi-Hardware project, we use KiCad as the centerpiece for various
|
||||||
|
hardware designs and enhance its functionality with patches or external
|
||||||
|
programs. This presentation will describe the complete workflow from
|
||||||
|
design to fabrication, introduce the various tools we use to complement
|
||||||
|
KiCad, and also briefly address common design rules.

Werner got hooked on Linux in the days of the 0.12 kernel and started
|
||||||
|
to get his hands dirty from early on with contributions like the LILO
|
||||||
|
boot loader, the initial RAM disk (initrd), and the MS-DOS file system.
|
||||||
|
Later activities led him into networking, with the Linux-ATM project as
|
||||||
|
part of his PhD thesis, and he eventually landed in the Openmoko project.
|
||||||
|
|
||||||
|
Having had a taste of hardware there, but eager to do more, he then
|
||||||
|
journeyed deeper into the world of electronics and finally joined the
|
||||||
|
Qi-Hardware project, where he now dabbles with making gadgets that aim
|
||||||
|
to blend software and hardware under common principles of freedom.

How it works:
|
||||||
|
\begin{itemize}
|
||||||
|
\item Walk git revision history
|
||||||
|
\item Check out project whenever schematics change
|
||||||
|
\item Run eeschema to make Postscript
|
||||||
|
\item Convert to PNG (find diffs, with highlighting) and PDF
|
||||||
|
\item Wrap in HTML
|

|
\end{itemize}
|

|
|
||||||
|
Issues:
|
||||||
|
\begin{itemize}
|
||||||
|
\item Nasty shell script
|
||||||
|
\item Resource-hungry (partial caching)
|
||||||
|
\item Large schematics get confusing

\item Projects spanning multiple repositories

|
\item Spread the word
|
||||||
|
\item Improve quality of libraries
|
||||||
|
\item Integrate patches into mainline KiCad
