I was working with the education division about a decade and a bit ago when they had an open source platform with sensors and motors. Then iRobot abruptly killed that division too, right as our project was getting going.

I haven’t felt good about that company since.

I know NiMH are way easier to charge, but lifepo4 has better capacity and way more charging cycles I believe.

The tricky thing with iron phosphate is that the voltage level between 75-80 and fully charged is very flat, so it’s difficult to reliably know the state of charge.

Switching to LiFePo and making the batteries easy to swap along a trip, is a better way to reduce fires.

Or solid state maybe? Not sure how flammable they are, but I know LiFePo are much lower risk than standard lithium ion (Nickle cobalt or whatever Tesla and the big Chevy trucks use )

Edited for spelling

There was a MacBook 12 inch like this that my business partner loved. It would last all day on a charge and he was building our app with it (Xcode and I think clang builds).

This was 10 years ago though.

It’s a contribution thing. He contributed enough to society to deserve to not worry about money for the rest of his life. It’s rare though since we have a bunch of billionaires who skim the rewards from huge swaths of the population who also have contributed their part.

The financialization of retirement is a huge part of the problem for the middle class (or what’s left of it, upper-lower-class is probably more accurate). We have to invest in these assholes in order to save for retirement. The harder workers in services, laborers, and fields don’t even get that.
