Automotive design and engineering
As a kid I appreciated the styling and outrageous specifications. Now proper design, development and engineering are what I’m appreciating and aiming for.

Recumbents have always been very interesting from a design perspective. I still want to figure out a more efficient transmission for this type of bike. Perhaps I should just build one.
Experience with digital photography from taking many photos with DSLR cameras. I have worn out a Canon EOS 300D and 350D, as well as a Canon kit lens and Tamron 18-200 lens. The Canon 50mm f1.8 prime is fortunately still ok.
