Couldn’t have timed that better if I tried… only a few days after sending out the layout for my next project, the prototype boards for the smart business card project came in. The shipping took about 2 weeks longer for these than the last order I placed at DirtyPCBs, but they made up for it by sending about eight extra boards, which was a nice touch
Hopefully I’ll have one populated and functional by the end of next week, at which point I’ll start working on a proper writeup. In the meantime, here’s a few pics of the bare PCBs.
The board is composed of a bottom piece, where all the components reside,
and a top piece, which has holes milled out for all the high profile parts.
Each piece has a large exposed trace around the edge, which will be used to solder the boards together. For now, I’m using the design Mathieu Stephan came up with, which he posted about on his blog.
Once I get this up and running, I’m planning on making a few design tweaks and personalizing it a bit for myself. If nothing else, I’m hoping this project will be a good introduction for me to the ATMega32 line of micro controllers, which I haven’t yet worked with.
