Joe Grand Talks Deconstructing Circuit Boards

With the exception of [Eric Evenchick], the Hackaday crew are safely back from Defcon and not missing in the desert. This means we can really start rolling out all the stuff we saw this weekend, beginning with an interview with [Joe Grand], creator of the JTAGulator, early member of l0pht, and generally awesome dude.

The focus of [Joe]‘s many talks this year was reverse engineering circuit boards. Most of these techniques involved fairly low-tech methods to peel apart circuit boards one layer at a time: sandpaper and milling machines are the simplest techniques, but [Joe] is also using some significantly more uncommon methods. Lapping machines get a mention, as do acoustic microscopy, CAT scans, and x-rays. [Joe]‘s Defcon talk isn’t up on the intertubes yet, but his BSides talk about techniques that didn’t work is available.

In case you forgot, [Joe] is also a judge for a little contest we’re running, and we asked what he’s looking for in a truly spaceworthy entry. [Joe]‘s looking for projects with a lot of effort put into them. Don’t get us wrong, project that require no effort can be extremely popular, but documentation is king. [Joe] thinks well documented projects are evidence project creators are building something because they want to build it, and not because they want to win a prize. That’s intrinsic motivation, kiddies. Learn it.
