As members of the maker community, we are always looking for creative ways to use hardware and software. This time, Patrick Lima and I decided we wanted to expand the Raspberry Pi's ports using an Arduino board, so we could access more functionality and ports and add a layer of protection to the device.

The pervasiveness of the Internet of Things (IoT) means nearly every product, from refrigerators to pocket watches, can connect to a network. For that to happen, all these products must have an embedded computer running a networking stack, and some of these products are almost impossibly small. That's where embedded software comes in: modern technology provides a tiny computer, hard-coded into a hardware chip, without any need for offboard CPU, RAM, or hard drive. read more

My philosophy: Start simple, improve over time, and aim for productivity. Background and foreground I start up xterm with this script: read more
