- mlyle 11mo agoYah, but that's a case of the package not being opaque enough.
- russdill 11mo agoCompletely unrelated and due to a design failure by the rpi folks.
- hughw 11mo agoIs it really so unrelated? Isn't it a case where a similar phenomenon -- radiation impacting a computer calculation -- happened and it's one we can all relate to more easily, and reproduce if we cared to, than high altitude avionics? Not necessarily disputing but it just seems like a relatable case that helps me understand the issue better. If it's a radically different case somehow I'm interested to learn.
- russdill 11mo agoNo, because it's a completely different kind of radiation.
- hughw 11mo agoDifferent band, sure. Same principle, right?
- russdill 11mo agoThe difference between ionizing and non-ionizing radiation is quite different. But for much of the radiation effecting electronics at high altitudes it's largely subatomic particles. And of course you can block the type radiation that caused problems for the rpi with a good piece of paper.
- hughw 11mo agoGot it. Ty.
