Projects
I'm a frequent user of public transport and enjoy building API clients and web services to provide as much transit data as I can find in a structured manner. You'll also find some energy measurement utilities and assorted minor hardware hacks that I was involved in here.
Note that all entries on this page refer to hobby projects that I started to scratch an itch or just because I felt like it. While I appreciate any and all e-mails, patches, bug reports and feature requests, please keep in mind that I am not obliged to do anything about them. I typically address those whenever I am in the mood for spending time on the corresponding project, which is anything between right now, an indefinite point in the future, and never.

Public Transport CLIs
Routing modules refer to public transit itineraries (i.e., getting from A to B). Status modules provide departure monitors at specific stops, looking up stops by name or coordinates, and often details on individual trains / journeys.
DBRIS modules interface with bahn.de and are a good choice for local, regional and long-distance transit in Germany. EFA and HAFAS modules are best suited for individual public transit networks.
