#22This is depressing. Single use disposable. Full of copper, gold, tungsten, halfnium. Will leach poison into the ground. Some of the most advanced technology of our age. Use it once, toss it in the trash.
Meanwhile the paper versions work just fine.

The optics on this seem to indicate that it is just a lateral flow test of some kind.
It's not even different. Instead of having to interpret a couple lines you have software interpret the strip and tell you over bt on your phone. So much tech for so little.

#24edit: was wrong about the test price. It should be $38.99 / ea test.

#26So my followup question is: I have a few of these, can I do anything with them once I'm done with the test? Hook up to the headers and reprogram? What about the Binax test? Or any of the other "connected" ones?

#27I worked at a company that was using these chips to control doors. They're extremely cheap chips, but writing code for them is not pleasant. Documentation is lacking and the tools people use to write code for it suck. Props to the devs who helped put this together.
Any chance I can reuse one of these boards given that I have a few of these test kits? Or are the tools so bad that it's not worth it?

If you read the full Twitter thread they explain that paper doesn’t work for everyone (the color blind and the incompetent, for example.) There is a use case, it just might not be for you.

Okay, I'm going to ask "Compared to whom?"
Nordic has been one of the better BLE chip manufacturers in terms of documentation, in my experience.
Most places use Keil tools directly from ARM. So, if programming these sucks, so does programming most embedded Cortex M4 chips. (No argument. Keil sucks. However, that doesn't mean that Nordic sucks any worse than anybody else).
And now you can program Nordic chips using Visual Studio Code.
