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

Is that really the responsibility of the person making the card?

This is the responsibility of the creators of the USB hardware, firmware, motherboard firmware, electrical design, OS developers / driver developers.

It should be safe to plug in a USB device by default

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

I think it's very considerate to not add lead to a business card people may put in their pockets.

Sure, the lead may cross one or two layers of cloth and migrate from the pocket to your skin and bite you.

More considerate would be to provide the card in a protecting sleeve (that would protect from all the bad, bad substances it may contain) or just use a good, ol' plain paper business card, posibly printed with "bioetical" ink.

The links from that page leads to https://wiki.sipeed.com/en/lichee/nano.html which is a Linux computer in form factor similar to a SD Card

Which reminded me of the good ol' matchbox web server:

It’s actually probably harder these days to build something that isn’t RoHS compliant as a hobbyist than one that is. The vast majority of what you can buy from Digikey and Mouser and whatnot will be compliant, PCB shops will mostly do lead-free HASL (though you’d want ENIG anyway if you’re going to use a stencil), and lead-free solder pastes are more common than leaded ones. Basically you’ll probably have to either use old stock parts or pull some really old solder out of the fridge as a hobbyist to end up with lead.

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…

You and your parent clearly shows the current boring, uninspiring state of HN community. Well done.

Now, where is the predictible sandboxing guy to counter your predictible "security implications" argument?
