thirtythreeforty.net | My Business Card Runs Linux

I'm an embedded systems engineer. I spend a lot of my free time looking for things I could use in future designs, or things that tickle one of my fancies.

One of those things is cheap Linux-capable computers, the cheaper the better. So I started diving into the very deep rabbit hole of obscure processors.

I thought to myself, “These processors are nearly cheap enough to give away.” After a while I hit upon the idea of making a barebones Linux board in a business card form factor.

As soon as I had the idea I thought it would be pretty cool to do. I have seen electronic business cards before, with various fun features including emulating USB flash drives, blinkenlights, or even wireless transceivers. I have never seen one running Linux, however.


So I built one.
