Could anyone recommend a budget tooling (has most features desired, please explain) to capture on wire like an oscilloscope. Help understand what kind of sample rates needed etc. features desired, cost and any recommended brand/models to get by. Thx!
The QSGMII signals in this blog are very high speed. Beyond the range of what you can measure with budget tooling. Even the probes for such lines are thousands of dollars.
There are some budget sampling oscilloscopes on the market, but budget is still mid four figures and up. That's before probes, cabling, and other things you'd need. Sampling oscilloscopes are only useful for repeating test patterns sent by SDK tools, not for capturing normal data as it goes by
It's possible to look at Ethernet signals with oscilloscopes in the budget range but you would need appropriate fixtures to tap the line. Even at those speeds, touching a regular oscilloscope probe on to a wire disturbs the circuit so much that it might stop communicating.
At the other end of the scale, looking at classic 10M Ethernet signaling is perfectly doable with a sub-$1k scope, and 100M should also be fine with anything 500MS/s or higher. Note that Cat5 is rated for a bandwidth of 100MHz.
Anyone know what are inside those tubes? Thinking to create this with a few younger ones and want to understand any risks should those tube breaks and something escapes.
The FAA will actually fully investigate this as the issue COULD be due to pilot error or equipment failure. So it is still potentially an issue outside of the weather.
Could someone recommend one starting out (something beginner could use and has enough, good functions for continued use into later advanced projects without running into limitations for 'most' projects).
Would be helpful to understand the what limitations might be encountered such at the frequency.
Buy a Pinecile[1] from Pine64. It's currently discounted to $25.99 (excluding shipping), and it's both cheap and has a great feature list that makes soldering a breeze.
We can maybe borrow from some past generational issues, but it seems old forms of media and societal problems are growing worse (e.g bullying, self-esteem, harmful cliques, peer-pressure, etc), or are certain areas getting better (e.g. respecting different cultures and differences, etc.)

I have to respect all the parents at this time learning to deal with such changes and no past to learn from with the technological changes. Was there ever a time destructive to "reading books too much" (e.g. bookworm)?
Would love to hear thoughts (ideas?) for what ought to be done for a new generation of children being born. What can we learn from the past here and what are some ideas of the correct approaches? Not 100% convinced about banning devices until some later time since technology is being integrated also in classrooms, so I wonder if that hinders growth.
Our strategy has been limited access, and I feel it’s not a great one. There’s a constant desire to be on a device and a large inability to think of what else they could be doing. Not helped by being a single child and papa not always feeling up to playing pretend Pokémon.
At the same time, it could be far worse. Whenever there are other kids outside/to play with they really easily fall back into a pattern of pure play. We’ve had whole days of just playing basketball too.
I’m largely resentful of my inability to play with devices when I was younger (see how well I turned out despite my parents saying I shouldn’t look at screens too much), and it affects the way I approach this thing.
It's been a challenge to me to figure out what's too much. If you let them, they will spend hours watching YouTube shorts, or tiktoks. I've removed YouTube from our TV for that reason. Also the devices are locked down using Google family, plus the screen pin code is only known by the parents. One of the most wholesome digital experiences I've seen is setting up a Minecraft server, and watching the kids have a build battle. You do need to set up grief prevention though, they will try to vandalize each other.
