Meh. What's the of a pin in input mode? Is it safe for a high value from another pin in output mode to sink directly to it?

I haven't found this discussed anywhere. It 𝘭𝘰𝘰𝘬𝘴 as though a pin in input mode has quite a high 𝑍 and sinks very little current, but I don't want to experiment just in case that's an invalid conclusion. πŸ˜”πŸ€”

In an other life I did a lot of Radio Frequency work. Transmission line principles were bread and butter.

This explains a lot in a small space. Recommended.

It makes use of a , one of the cleverest bits of maths I know. There is a link on the page I gave that jumps to an equally good explantation of smith charts.

And it's friday again, time for . Established by @TexasObserver to promote great work from some of the newsrooms here in Mastodon.

This time with an article from @ghonsel:

Longer life for used batteries

Many old batteries can be saved by replacing individual cells. A new process makes it possible to assess more quickly whether this is worthwhile.

Even as a enthusiast, I've had massive problems really understanding the notion of . I can do the math, but it doesn't really internalize, and I'm always thinking about it in a manner similar to having to use tongs to do a jigsaw puzzle.

Until yesterday, when someone describing why an explosion in the air doesn't move into water easily, and the same for an explosion in water:

It's an impedance mismatch.

And the scales fell from my eyes.
