Travis Goodspeed's personal blog at travisgoodspeed.blogspot.com covers security and hardware. Since 2010, 14 different Hacker News readers have linked it 16 times, most often “Emulating USB DFU to Capture Firmware”. The last post was in 2013, but the archive is still widely read.
Too few sampled comments (8) to say how often HN recommends it.?
Why HN links it
HN readers link this blog for hands-on hardware and security hacking posts, such as USB dead drop emulation, Bose headphone reverse engineering, and smart meter and GoodFET tooling.
Summarised by Claude from a sample of 8 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

HN discussionYou'll probably see this on the Sparkfun saga, but the way to remove it at the Atmega lab (with a hotplate and acetone) is quite dangerous. Don't try that at home. Instead, drop the whole chip in a test tube of fuming nitric acid at room temp, and let it work slowly overnight. Anything with fuming nitric acid is dangerous, but this is much safer than the hot plate method. See this tutorial by Travis Goodspeed: http:…

HN discussionThe point is it's important to define a new spec if you are being "liberal" in what you accept. For example, while RFC 4180 defines line endings as CRLF, it might be reasonable to "be liberal" and accept files with just LF if and only if you add a rule similar to <line-ending> ::= "\r\n" | "\n" to your input grammar, and properly recognize that the input matches that grammar before using any parsed values. It's an e…

HN discussion>some people noted that some 'hardware' attacks can't be seen because they use original parts. You can have original looking part. Imagine a 8Mbit SOIC SPI NOR flash chip. Looks the part, belongs in its spot, you decap it and it sure does look like a flash Die with its normal Flash controller.
