1Making Hardware with KiCad and Friends
2
3KiCad is a well-established Open Source EDA suite that provides tools
4for most of the basic tasks in circuit design. In larger projects,
5and especially those of an open and collaborative nature, additional
6requirements appear that KiCad can only partially satisfy.
7
8Specifically, collaborative projects benefit from visualization that
9helps to quickly follow the work of others and to track a project's
10revision history. Furthermore, an automated and thus easily
11reproducible workflow lowers the barrier of entry and avoids costly
12mistakes.
13
14In the Qi-Hardware project, we use KiCad as the centerpiece for various
15hardware designs and enhance its functionality with patches or external
16programs. This presentation will describe the complete workflow from
17design to fabrication, introduce the various tools we use to complement
18KiCad, and also briefly address common design rules.
fisl2012/bio.txt
1Werner got hooked on Linux in the days of the 0.12 kernel and started
2to get his hands dirty from early on with contributions like the LILO
3boot loader, the initial RAM disk (initrd), and the MS-DOS file system.
4Later activities led him into networking, with the Linux-ATM project as
5part of his PhD thesis, and he eventually landed in the Openmoko project.
6
7Having had a taste of hardware there, but eager to do more, he then
8journeyed deeper into the world of electronics and finally joined the
9Qi-Hardware project, where he now dabbles with making gadgets that aim
10to blend software and hardware under common principles of freedom.

318
319\begin{frame}{Schematics History (cont'd)}
320How it works:
321\begin{itemize}
322  \item Walk git revision history
323  \item Check out project whenever schematics change
324  \item Run eeschema to make Postscript
325  \item Convert to PNG (find diffs, with highlighting) and PDF
326  \item Wrap in HTML
327\end{itemize}
328
329Issues:
330\begin{itemize}
331  \item Nasty shell script
332  \item Resource-hungry (partial caching)
333  \item Large schematics get confusing
334  \item Projects spanning multiple repositories

431  \item Workflow is complex and needs careful consideration
432\end{itemize}
433
434To do:
435\begin{itemize}
436  \item Spread the word
437  \item Improve quality of libraries
438  \item Integrate patches into mainline KiCad
439  \item Finish BOOM and write brdhist
