I am astonished just reading this, what have been some reactions handing these out?

While it's a fascinating project I'd have some security concerns about plugging someone's USB business card into my computer.

That’s if you even have a USB A socket anymore!

If only they'd invested more into a professional looking email address. Pretty cool nonetheless!

That makes no sense. This guy isnt advertising his mad "registering firstnamelastname.com" skills, he's advertising his mad embedded engineering skills.

From the project webpage:

> It has a USB port in the corner. If you plug it into a computer, it boots in about 6 seconds and shows up over USB as a flash drive and a virtual serial port that you can use to log into the card's shell.

The parent of this thread has a valid point here and the insecurity implications of this is nefarious if one isn't careful.

While it is a technically cool fun project, I can imagine a bad actor taking this to DEFCON/CCC or even a tech-centric concert and mass producing this to emulate a USB drive, but is also a keylogger or a remote access tool of some sort which reminds me of the nightmares of BadUSB.

While I'm impressed by how low the bill of materials is, I can't but put into perspective the kind of skills the authors of the post has, and how mindbogglingly expensive they must be. Contrary to what the media says, it seems that the digital era has made (some) human beings more essential than ever ...

Well, it is appropriate as a business card for an embedded systems engineers, not so much for a system security one!

More seriously, I never managed to understand the "obsession" with ROHS (this here is just an example):

>I made sure to have a lead-free process—the boards, parts, and solder paste are all RoHS—so that I wouldn't feel bad about giving them to people.

I mean, you are creating something that (besides being very nice) is not needed, that very likely will end soon in the trash (and that contains anyway a few grams of "far from clean" materials) and you worry about the tiny amount of lead in the solder tin?
