There's a pun about "queso factor" buried at the bottom of the comments too.<p>This is a nice little article, there's something very Bob Pease about it. And it's good to remember that there can be quite a lot of margin in controlled impedance situations. I've done things like USB2-over-flat flexible cable for test fixtures before.
Omg this is such great read! I’m nominating for best of HN! It’s got silliness, existential reveal, thorough methodical detailed explanations accessible to laypeople, excellent prose and is just a joy.
Wow. This is so far up my alley that my masters thesis was on implementing testing from 802.3bj and I have made passive microstrip filters in a class.<p>It’s cool that he simulated the eye diagrams, and getting your hands on a real transmitter is not easy, but I think it ends up being a little too optimistic. I don’t think this is meant to demonstrate a real world channel or else he could have just pulled IL and RL limits from various specs. Really cool stuff though.
This of course begs the question: which cheeses act as the most efficient substrates, and why?<p>I wonder if there's any organic materials that would work even better.
