I’ve written an email to Linux Format all about it.
I’ve particularly enjoyed the 10 Great DIY Projects and Hardware hacking articles. I hope you are able to continue with similar articles in future. Linux is a great OS for these hobby activities. I particularly enjoyed the Hardware hacking article as it was a bit more in-depth than the DIY projects which were a bit brief.
I’d be interested in a project using Linux to communicate directly outside the PC. The Arduino appears to be capable of this but doesn’t appear to have a Linux version of the serial proxy software.
