Not an area I'm familiar with, but do the chips really handle up in the gigabit IO? I thought they just handle connection setup. I had thought the gigabytes were not processed at all by the chips. They just flow through the wires. ?
The chips in an active TB cable perform signal retiming. https://plugable.com/blogs/news/what-s-the-difference-betwee...
So much in there: so much hand-soldering of SMD, the way he made an SMD resistor bridge to bodge his MOSI/MISO mixup, using the Bambu 3D printer as a test harness (with pogo-pin attachment) to test his "blades"… (I thought he was going to end up with R2-D2; the way the design was going…)

My fav job was an internship with a EW company that made these massive rackmount radar systems. My boss, the lead engineer, loved blue LED status lights. So the massive boards we made had hundreds on them. There were thousands total in the rack. GPIOs, busses, fpga signal outputs, all got an individual LED and mosfet. It was crazy when it was running. You could visually debug a bus, if you wanted to.
My dad programmed minicomputers, which normally had LEDs on the front panel that showed the binary contents of the program counter, and maybe the current instruction and some other status indicators. I remember him saying that he could tell if his program was running normally by the patterns in the lights.
The determination to pull through a project of this scale is mind blowing and the joy is contagious.
For me it's the skill. So many things you have to be good at to build this. Really impressive and slightly jealous.

This is still a partial build, so things might change a bit.
For me, I think it’d be cool to have the boards back to back so LEDs would always show.
Ok, I watched it, it looks amazing, what's it for/do ?
@3:10 “you need to consider 99.9% of the power is converted to heat” uhm that would be quite an efficient heater you designed there!
Not really? The best heaters are heat pumps which can under typical operation reach 300-500% efficiency (COP). Technically they aren't converting the electricity into heat, but for arguments sake here about heaters we only care about electricity consumed to heat generated.
The heat pump takes input heat and just concentrates it. It turns out that the energy spent on concentrating heat also turns into heat, so you have a 100% efficient heater.

Yeah, i was totally confused with efficiency, still curious about that 0.01% now tho
There will be an LED somewhere, so some of it gets converted to light, rather than heat.
Essentially, light is one of the principal agents of entropy.
