Working with headphones on usually means youd rather not be bothered, but sometimes it means youre just listening to something while you work. If you want to be available despite your cans being on, why not build your own alert button Enter developer Nick Sypteras, who wanted to solve the problem of coworkers requesting his attention while his headphones were on. Working in a cubicle, he wrote, Theres no way for a visitor to my desk to get my attention other than by waving their hand in my face, making loud noises behind me, etc. So he broke out the soldering iron, a Staples Easy Button, and an Adafruit microcontroller. Dear Lifehacker. I am condemned to being stuck in a small cubicle with low walls. I know Lifehacker Read more Read. Sypteras wrote the code to send his Slack alerts in Micro. Python, a version of the programming language designed for microcontroller boards. The Adafruit Feather HUZZAH microcontroller listens for a change in value based on whether the button was pressed. Using Slacks API, he was able to send messages to a private channel he created specifically for his desks easy button. While the message just lets him know hes got a visitor, you can get fancy with it and use Slacks API to attach more info to your alerts.

Today, billions of devices are Internet connected, Io. T standards and protocols are stabilizing, and technical professionals must increasingly solve real problems with Io. T technologies. Now, five leading Cisco Io. T experts present the first comprehensive, practical reference for making Io. T work. Io. T Fundamentals brings together knowledge previously available only in white papers, standards documents, and other hard to find sourcesor nowhere at all. The authors begin with a high level overview of Io. T and introduce key concepts needed to successfully design Io. T solutions. Next, they walk through each key technology, protocol, and technical building block that combine into complete Io. T solutions. Building on these essentials, they present several detailed use cases, including manufacturing, energy, utilities, smartconnected cities, transportation, mining, and public safety. Whatever your role or existing infrastructure, youll gain deep insight what Io. T applications can do, and what it takes to deliver them. Fully covers the principles and components of next generation wireless networks built with Cisco IOT solutions such as IEEE 8. Wireless Networking in the Developing World is a free book about designing, implementing, and maintaining lowcost wireless networks. Yokogawa has more than 45 years experience in the development, design, and manufacture of pressure sensors and pressure transmitters. The DPharp series of digital. Wi Fi, IEEE 8. 02. Mesh, and Lo. Ra. WANBrings together real world tips, insights, and best practices for designing and implementing next generation wireless networks. Presents start to finish configuration examples for common deployment scenarios. Reflects the extensive first hand experience of Cisco experts. Online Sample Chapter. Securing Io. T. Sample Pages.
