I recently started a brand new column on TheNewStack.io about hardware hacking. The series walks through tips, techniques and projects for the physical computing hardware hacker.
The first edition, Off-The-Shelf-Hacker: The Physical Computing Stack, introduced the reader to the exciting new world of off-the-shelf microcontrollers, sensors, actuators, Linux/Free software, NanoLinux systems and companion topics like the Arduino, Raspberry Pi, ESP8266, and other tools and designs of the DIY (do-it-yourself) and Maker movement.
Future stories will take readers through hands-on fabrication tutorials, using various programming tools/frameworks and discussions on using sensors, micro-controllers, nano-Linux systems and interfacing to various electronic/mechanical devices.
The articles will appear weekly, typically over the weekend.
If you want to get into hacking hardware and building physical computing projects, be sure to check it out.
