The Intel Edison
I'll stop being wordy, though and just index the posts that I've creating (and am still creating) for the Intel Edison. Here they are.
Getting Started with the Intel Edison should help you pull it out of the box, mount the device to the dev board, flash the latest OS to the device, and get your toes wet writing code.
Using Visual Studio to Write Node for Devices (queued) will bring a bit of awesome to coding for devices. You'll have a rich development environment including remote debugging so you can actually step through breakpoints and watch your gadget react!
Network IoT Devices (queued) is all about getting devices to form local or extremely broad networks that form huge logical apps and scenarios.
So you can actually check out posts in progress before I've polished them and called them done. Do please feel free to engage in the comments and offer feedback, advice, or questions.
