    The additional battery weight would be something under 250kg (having handled a few Leaf battery packs), and wikipedia says the Niro EV is about 1700kg

    Fun historical twist: New Zealand rotary phones used a reversed mapping between digit and pulse count - here the number of pulses was 10-digit.

    There are techniques for "stack"ing transistors so that the individual swtiching devices see potentials that are within spec and much lower than the voltage switched by the overall…

    Whoops, yes you're correct. Serves me right for looking at some SEO spam link! Main point was that bronze is much more common in marine applications than brass - I wouldn't be surp…

    Because it's in the Arkansas River drainage?

    Ah, that helps, thanks. It's a bit academic, but set theory doesn't really apply to such fuzzy human things as knowledge and experience. Repairing and designing are different pursu…

    I've rebuilt several motors, transmissions, various other mechanical contrivances. Sometimes with decent documentation, sometimes not so much. Also done a bit of amateur machining,…

    Directly, the temperature isn't as big an issue for operating tapes/drives/computers, since they are inside temperature-controlled buildings. There are indirect problems though; th…

    If by "station wagon" you mean LC-130 ;) IceCube switched from tapes to hard drives I think in 2015 or 16. In 2014 we spent a lot of time fiddling with tapes and drives... At that …
