That's slick! And I'm glad to see the models for the internal bits available. I've got pieces for a YARH handheld... laying around, mostly, since other projects came up and I'm less motivated to figure it out when I can't get any Pis for sane pricing right now. > EMP Shielding Not to drag this thread too far off topic, but this concept has been coming up a lot around me in about the past week. Is there something specific that's been coming up lately about it I've missed?

I wonder if it's the whole "russia might drop nukes or EMP-blast a large portion of the globe because of what's happening with ukraine, i better EMP protect my electronics in case they get fried"

  From my casual research EMP is much less of a problem than people seem to think it is. Modern electronics are small, and don’t have large antennas where a large current can build up. Power lines and such would be vulnerable, but that’s about it, unless you were sitting right underneath or within a few miles of a nuclear explosion, in which case you have bigger problems to worry about.

    And raspberrypi's will probably know where the nuclear explosion has taken place. https://www.raspberrypi.com/news/xenon-death-flash-a-free-physics-lesson/#comment-1215364 https://www.raspberrypi.com/news/xenon-death-flash-a-free-ph... Its the airburst nukes (ones that detonate just above the ground) that are most harmful for life as it spreads more, its what the Chinese had been testing which got them some criticism a few years or so ago.

  I think it is this that has been making the rounds. https://defconwarningsystem.com/digest/wp-content/uploads/2021/02/Russia-EMP-Threat.pdf https://defconwarningsystem.com/digest/wp-content/uploads/20... I'll post it new in case more people want to panic ;)

    Ah, that looks... likely. Thanks! I know it's been a concern of various groups at a low level for some while, but it's been popping up far more than I'd expect lately, and I was curious as to what triggered it. The people who've brought it up (at least in person) don't seem particularly well informed as to the technical details, so I assumed there was something talking about it, I just wasn't sure what.

    It’s pretty interesting to compare the report from a year ago when Russia was still seen as some super advanced military threat with the actual performance of the Russian military in Ukraine over the past almost 3 months.

      Russia is still a military threat, despite their performance. There were a lot of instances of Roman millitary in their prime performing poorly (ex Septimus Severus's wars in Caledonia) for a long period of time. It's just 3 months of poor performance, but their potential for war is still very high.

Is it EMP or EMF/EMI? I can certainly imagine magnetic pulses getting through the copper and inducing higher than expected voltage spikes in the internals.

  It's not EMI because it's the cardboard box that he puts the pelicase into. And quite honestly, that cardboard box won't do a whole lot. You probably have pretty good cell reception in it.

I'm not aware of a particular occurrence in the past week. Noticing the topic of EMP shielding could be due to a mix of Russia's vague nuclear remarks, people finishing Neal Stephenson's book "Termination Shock," and frequency illusion. https://en.wikipedia.org/wiki/Termination_Shock_(novel) https://en.wikipedia.org/wiki/Termination_Shock_(novel) https://en.wikipedia.org/wiki/Frequency_illusion https://en.wikipedia.org/wiki/Frequency_illusion
