The Data Dial Dashboard brings back the fun of old-school analog dial gauges while updating them with internet connectivity. In this project we will use an Arduino, Ethernet shield, and 3 servos to create a system for tracking global earthquake activity. The data is pulled from the USGS Real-time Data Feeds page. With a little hacking, it is easily adapted to track your unanswered e-mail count, the speed of your internet connection, the price of rice in Rhode Island, or any other data you can scrape off the 'net!

FM transmitters can be complicated to build, but not this one — it's about the easiest you can possibly make. And though the science of radio is well understood, there's a magical, emotional quality about it that we don't often stop to appreciate. Building your own radio receiver — or better yet, transmitter — makes it real again. You will not forget the first time you pick up a transmission broadcast from a device you soldered together, yourself, from a few bits of copper, carbon, plastic, and wire.

The Internet of Things (IoT) is essentially the internet we already have, but now it’s not just humans using it — all kinds of devices are using it too. Here's how to connect your fridge to a free IoT data service so it logs every door opening and even tweets when you're holding it open too long searching for midnight munchies! Another cool Internet of Things project from MAKE contributors Tod Kurt and Mike Kuniavsky.
