RE: Technological suggestion
Furthering this subject...
what about emergency lights for the home?
Yeah, I know, it's called a torch..... but I have an idea to make standard lamps with lithiums in the base that are powered from a wall wart, have an LED bulb for normal use and fail-safe to the battery supply if the mains fails. It would also be designed to cut light output gradually over time unless it was 'reset' to full brilliance.
A couple in the living room and bedroom and you'd never be kept in the dark!
I also fancy putting Red LED's in the top crosspiece of all door ways (downlights) that light automatically in a power fail situation.
and lastly (for now!) I'm looking for a stand-alone connector for Aldi power tool batteries. I want to fit battery receptacles in strategic places to power some devices (modem, lights, phone charging etc). The batteries are pretty good (value and quality) - not like the tools themselves.....
