Internet of Things with the Arduino Yun

Internet of Things with the Arduino Yun is a well-paced practical introduction to creating and exploring DIY smart devices. Or, as the book phrases it; “projects to help you build a world of smarter things”.

Each example project explores a specific real-world scenario similar to that of existing applications of Internet of Things (IoT) technologies within industry. Each example also exposes the reader to concepts and techniques that should be easily transferrable to many other projects and applications. Covering the subjects of sensing, data collection, automation and long-term presence, the book gives readers a good overview of the broad concerns that need to be considered when designing smart devices.

Impressively, the book doesn’t require a great deal of prior knowledge to navigate, though some interest in coding and electronics is of course necessary. Those already familiar with Arduino will benefit from the exploration of the networking aspects of Arduino Yun as they are a bit different to control than what one might be used to with prior versions of the Arduino. The book would make a great companion for those unboxing an Arduino Yun for the first time.

Make a custom USB button pad [Pt III]

In my previous posts I was modifying a traditional plastic-housed USB Keyboard that had a chip inside it like the one below:

These contact points had to be scraped or sanded clean in order to solder to them, however scraping them made them quite thin on the surface and therefor quite brittle.

The chips inside the cheap, flexible silicone keyboards (above) are actually much easier to work with because they have a line of female headers instead of contact strips. This allowed me to solder up a vero board to act as a breakout shield (below)

I bought some female-female jumper cables which I will be cutting, stripping and placing a n/o button between. This allows me to plug and play the buttons as needed with low-risk. The layout of the header pins on the vero board was determined through shorting sections of the chip with test leads and figuring out the combinations necessary to make a minimum of 25 unique combinations/keystrokes.
