This is also why open source wearables can't have the best PPG heart rate/SPO2 tracking.

There are only about 4 PPG analog front ends still in production that don't require an NDA and the Max86141 is the only one worth anything it seems.

You can't do analog front ends with any small FPGAs that I know of and it is simply to large to do it (well, at least) on a small wearable with discrete components.

Definitely useful skills if you ever need to fix any metal furniture or make a metal structure.

Every corporation proving like always that it hates its workers and only exists for executive profit.

And ironically, the danger of teslas is underreported and downplayed. Don't you still burn a lithium-firey death if the electricity goes out during a car fire? There have been many people that have died from that insane intentional design already...

For consumers yes, but an AR glasses for technical workers that (for example with an electrician), you could mark and highlight cables in AR that you are working on/ignoring or being able to auto search and send IC identifications on reverse engineering a PCB would be genuinely useful.
