Chatting up grannies
Disclaimer: I received this book for free through the O’Reilly Blogger program. is a very short “book” on RFID (Radio Frequency Identification), a way to tag and identify objects over varying ranges, and how to use Arduino to create a few interesting RFID projects.The book assumes that you have some experience with Arduino and micro-controllers (i.e., do you know what a breadboard, jumper wires, and circuits are? We start with a very brief introduction to RFID, follow up with two introductory technical tutorials on Arduino, and end with a fairly simple home automation project: Between my officemate and me, we have dozens of devices drawing power in our office: two laptops, two monitors, four or five lamps, a few hard drives, a soldering iron, Ethernet hubs, speakers, and so forth.As always we’ll be laying out our social challenges on the icebreaker wristband for you to fulfill with cash bonuses for winners. Our aim was to put on the biggest social event of Freshers week...Depending on which city you're in, we may be bringing our infamous inflatables party The Big Freshers Blow Out. what happened became a legendary tradition that has since seen over 200,000 guests and transformed the way we do freshers in the UK… Even when we’re not here, the room is drawing a lot of power.What devices are turned on at any given time depends largely on which of us is here, and what we’re doing.This project is a system to reduce our power consumption, particularly when we’re not there.When either of us comes into the room, all we have to do is tap our key fobs on a reader mounted by the door, and the room turns on or off what we normally use. The reader by the door reads the presence or absence of the tags.
We don’t need to tell you how to make friends, but we know how to design social challenges to make sure you leave with a load of friend requests, group selfies and faceswaps. Seven years ago we ran a little show at the Students' Union in King’s College.
The book is only 28 pages, so it’s more of a long tutorial than a book, but it still acts as a good introduction to RFID.
