That is why I provide sources. Inspect them and tell me if you find anything scary. At most, maybe i forgot to implement some corner of USB-CDC spec :D

But you have no way to prove your business card actually runs the released source. And if users are expected to build from source, the card becomes less meaningful. Similar to the original comment, I fully agree this is a very cool thing. But a business card, which is by definition given to people that likely neither know or trust you, is probably not a particularly good application for it.

Consider this article my business card, and the physical artifact produced by it - a bonus artwork :D

"Hey, stranger! Here's my card. Plug it into your computer's USB slot." Cool project, but as a business card, making someone think they're about to install Stuxnet might not be the best first impression. Heh.

On the other hand, if you want to covertly infect someone's computer, probably don't etch your name and contact information prominently on the PCB of the infecting device.

Thinking it this way, the card definitely work very well, excellent job!

I agree it's cool; that's why I prefaced everything with "Cool project". > the world advances much more via optimism than pessimism I don't think that's a slogan infosec folks frequently adopt.

Infosec folks should live a little. You can have more than one computer and not everyone is a head of state.

It’s all fun and games until your wife’s nudes or your most private messages are leaked.

"My business card emulates a long-obsolete MIPS-based DEC computer, which then runs Linux" is a more accurate, and certainly significantly more impressive, description :)

Just you wait, i am working on booting ULTRIX on it, and then hopefully emulating JAZZ system and booting windows NT (video provided over virtual vnc over virtual ethernet over usb)

As if the ulcers gained from Atmel's DMA implementation weren't enough, you just have to delve deeper ;)

Excellent work, excellent writeup. Hopefully those lucky should who receive these cards from you understand how much sweat and blood went into them!

The same could be said about a portfolio website because there could be a drive by on it.

That really is the worst possible DMA engine. Given how those tiny cortex M0s rely on DMA to get pretty much everything done, it is confusing why atmel put a basically useless DMA engine in place.

That’s why you etch someone else’s!

Fun story: since the kernel is kept in a FAT partition that Linux can (and does) mount on /boot, and since gcc works, one of these cards is currently sitting on my desk compiling its own kernel, so that i can then "cp vmlinux /boot; reboot" and have it boot a kernel built on it.

Please do post an addendum to the page with the time it takes:)

I was contemplating something like this as I’ve been thinking about a modern business card. I don’t need to run Linux, but I do like some degree of interactivity and uniqueness associated with something I could hand out.

Perhaps something like this: https://youtu.be/_BSfO9LAIqg

Looks cool, has NFC and flashing LEDs and fits in your wallet.

The NFC chip can be reprogrammed with an app from your phone.
