VCs don't generally want to see a portfolio of ideas. You're supposed to be the expert: they expect you to choose. What they want to see is a group of smart founders who plan to work in a promising area.
Also, they're generally leery of consumer electronics. Not that you shouldn't do that, but if you do, you should do it a la Meraki: make version 1 yourself in your basement, get ramen profitable by selling it to early adopters, and then go to VCs once you can show it's already taking off.
Thank you for telling me that probably would not have worked, and about the reluctance regarding consumer electronics. It makes sense they would be so, for the very reasons that are hindering me. (high initial investment, IP infringement risk, multi-country compliance, etc).
