Also pictured, this is what a 5016 test point clip is *supposed* to look like when an industrial reflow oven does the job.
And this is what a 5016 test point clip looks like when I hand solder it instead.

About time the boards started coming together (with 2x4 ribbon cables, and only half the potential sub-boards connected).
Notably 3 different eras of greatly miscalculating the actual brightness of the stupid super-bright green indicator LEDs. I corrected this on the newest (top), and in any case those are the only on-board LEDs which are intended to be user visible (light-piped sideways).

Status: Have enough shell hacks to enable power and output to LED strings. Just need to port my RP2350 WS281x GPIO programs to whatever hell zephyr requires.
This deliciously demonstrates what went _right_ with tech in the last couple of decades:
* If you have a technology which is demonstrably achievable today, but impractically expensive, then it *will* eventually become cheap enough, and sud…
In fact, Moore's Law (re-reading the original print e.g http://cva.stanford.edu/classes/cs99s/papers/moore-crammingmorecomponents.pdf) talks _separately_ about cost and count:

Which is not to say there aren't some nice things emerging in the high-efficiency/low-cost space, but most seem to be efforts which started long before the requirement of "AI" in the title. Everything else is going to be run on a shoestrin…
But herein lies another destructive thing about the "AI" craze: it's sucked all the air out of the room for any advances if they can't be tagged with the term "AI". I've heard from many who are dismayed that nobody is putting much effort i…
Not to labor a point, but one only has to look at wikipedia https://en.wikipedia.org/wiki/Transistor_count to see that there's no trouble in chip *packages* still exponentially increasing in total transistor count. (if you don't exclude on…
Meanwhile all of Big Tech is suffering from survivorship bias, believing they are packed full of genius executives, and about to bring humanity into a glorious golden age brought about by (actual) AI. They're going to destroy so much, beca…
It is dismaying to think that the real reason for advances in computers in the period ~2000-2020 is simply because the One Trick which executives understand—borrowing and spending vast sums of money—was during a part of the Moore's Law cur…

I feel the need for an obligatory "That is the common misstatement of Moore's Law" but it's hard to keep up.
Not cost. Not speed. Not performance.
Number of transistors. That's all.
