Relationship to electrical engineering[edit] Electronics is a subfield within the wider electrical engineering academic subject. An academic degree with a major in electronics engineering can be acquired from some universities, while other universities use electrical engineering as the subject. The term electrical engineer is still used in the academic world to include electronic engineers.
In the old days there was a gizmo that plugged into an outlet that you then plugged your light set into that made the set blink on & off. It's so simple that it isn't made anymore. All I want to do is make an LED light set blink on & off. I don't want computer control.
Just five years ago, a 200-lumen flashlight was considered amazingly bright. Now, advances in technology have made it possible to increase the power of even small flashlights to emit beyond 500 lumens of light, which is more than enough to illuminate a room and cause temporary blindness in suspects.
