As electronics have shrunk and power requirements have gotten less demanding, its no surprise that were starting to wear our electronic creations. Todays microcontrollers are tiny micro-sized computers that can be embedded into many projects--especially wearables. And they are perfectly happy running off a coin cell or rechargeable lithium polymer battery. This issue explores the latest trends in microcontrollers, with a special focus on wearable and lightweight boards. With 34 projects inside, you can build everything from a smart watch to your own electronic garments. A special section on Intels Edison tells you everything you need to know about this powerful, inexpensive, and lightweight board.In this issue: Electronics, wearables, and microcontrollers The "Mech Runner" 25 MPH boot DIY conductive ink Adafruit FLORA projects Electronics meet fashion Software-defined Radio 3D printer reviews Fun things to CNC
