Case in point, SiLabs for one could not get it right - I have reasons to believe that the CP2102N that I had to replace is secretly an LPC microcontroller in bubblewrap.

No, unless you're using LPC in a generic sense instead of referring to the Philips/NXP ARM product line. There's strong evidence to suggest that the CP2102N is a pre-programmed EFM8 which would make a lot more sense as they are both from Silicon Labs.
Anybody got a syringe I can use to squeeze the magic smoke back into this?

I was actually referring to the specific manufacturer devices, but you are probably right. My main point though was that even this "hardware" bridge is just a pre-programmed uC, and I wanted to show that developing something like that is not that trivial, as even a big silicon company like SiLabs wasn't able to get it right, even though their possibilities (both in budget and testing) are obviously way greater than of a lonely hacker's.

On a different note: It seems I didn't get into the Mailbag video, but I'll hope for the next one :) Either way funny to me that Dave tested only two gadgets in the current video. Probably because testing the USB scope took up most of the time budget.

Would you share the information how the deal with the enclosures turned out?

We managed to obtain a used mold and modified it for the muArt's enclosure. It cost me about 2.2k$ one-time, plus the cases are 0.6/piece at an MOQ of 1000. These are solely production costs. As for tec4data's engineering services, we'll work together on other projects (bartered).
