You gotta be kidding, of course they have the time, I did work at the computer lab and as a student position I was allowed to even do homework when it wasn't too busy. I would think Dave will not only allow it but he can probably mentor you at the same time.
Okay, I understand that the hours are very flexible. Nevertheless, 30 hours a week comes to 6 hours per workday. I am currently studying electrical engineering and I have no idea how I could squeeze an extra 6 hours of work into my day. Not to mention driving to and from the lab.
As for the tasks being for a full blown engineer I don't see where you get that.
Oh, let's see:
-Managing production, ordering components, juggling with fabricators, assemblers
-Investigating, designing, developing, testing and debugging new products
-Dev. tool setups and evaluation
-Forum and website maintenance
-Production of blog content
Essential skills:
-Analog, digital and embedded project design
-Drawing schematics, designing PCBs, coding firmware and PC apps
-Soldering, construction and debugging
-Writing documentation
How is this not a skillset of a full blown engineer?
