I don't see much about hardware hacking on CPunks. [...]
I maintain FirmwareSecurity.com, a blog focused on firmware security and developmen, mostly UEFI-focused. Hardware security is a topic, since most firmware is very hardware-specific. It isn't a fancy blog, I still haven't learned WordPress, it is mostly a paragraph or two of text and a few URLs for a topic. I try to put personal research here so others can benefit. The sad thing is I was looking for a better source and haven't found it, so my lame blog is nearly the best there is. :-( There are a few who teach hardware hacking classes, look at the pre-conference training offerings of the normal infosec conference circuit events, Black Hat, Def Con, Can Sec West, Infiltrate, REcon, Troopers, etc. Look into the Stanford.edu LiberationTech mailing list, there's a lot of personal technology security/privacy issues there, more for activists but similar to OP's list of topics. I'm not sure of the latest citizen-focused guidance for physical+cyber security. I expect there's a link to the contenders on the LiberationTech list. There is more happening on hardware/firmware security on Twitter than on mailing lists. It would be nice to have a hardware/firmware hacking mailing list. Not sure if some of the younger security researchers and hackers will be able to spend time away from Twitter/Facebook/Reddit to contribute to a mailing list, though. :-(
I'm working on influencing security in embedded, e.g., writing and designing secure systems (comprehensively, starting with arch & code.) It's an educational effort with embedded ISVs and OEMs at every step, you can presume the market, if they're thinking of security at all, is currently buying into 'fire-walling' and 'obfuscation' approaches.

I'd love an URL to the above embedded security work, if any exists!
