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.
