That is a great video. He speaks all we think/feel about!

I agree with a lot of that. On the flip side I sometimes wish family members would ask me about something rather than just taking care of it themselves. I remember my grandmother had major appliances replaced several times without even asking me if I could look at the old ones. I would have been more than happy to fix the old ones because they were cool vintage things and it's the sort of thing I enjoy doing. With most of my family it just works out, I help them out with things I can do and they help me out with things I can do. I have several friends that are similar, they are useful to me in one way or another and I am useful to them, I try to keep the favor bank loaded up so things are more or less even. Generally it doesn't seem right to charge a friend for labor, although I do expect them to pay for materials. I'm happy to help them out, although I do generally expect them to work alongside me, even if it's just chatting, passing me tools, keeping things organized and bringing me beers.  I long ago weeded out most of the people who only came out of the woodwork when they needed a favor.

Some time ago, I found this nonsense stops with a simple "I wont touch it while ever it's got Windows on it."

However, I'm sure everyone would like their own personal sys admin.

I ran into this problem often with woodworking.  'Make me one of those' would be closely followed by 'I can buy 5 of those at Walmart or IKEA for the same price.'  Now I gracefully say no and change the subject.

Hang on a minute... this Chinese "protection" device draws 80mA from the battery, all the time? And it's meant to stop the battery going flat?

Even 16mA is a lot to waste on standby. You're right that a MOSFET would be the way to go, but if you prefer the idea of a mechanical contact, a latching relay would require zero current to keep it in position. Your PIC can easily generate a short pulse to switch the contact position when the battery voltage crosses threshold.
