As a musician and engineer, I'm interested in musical projects that also involve electronic design - in that order!
As an electronic engineer and developer with a job history in telecommunication, semiconductor and automotive industry, I've always been interested in noticing how technical projects come and go. My common learning :
"Engineering is considered sustainable when you think of it as the job to 'develop the future' based on real world requirements - On the other hand engineering resources are wasted - and this might be too often - when you think of it as the job to develop 'just because you can'.
