Build Your Own Harry Potter Style Wizard Dueling Wands
Enhance the Experimenter user interface with a rotary encoder using the PIC24F timer peripheral set and its interrupt capability.
Joe Grand takes a closer look at the electronic aspects of his different builds from the popular Discovery Channel show Prototype This! This time, it’s the wristband GPS transmitter.
This particular application is for a compost monitoring device, however, you’ll learn ways to incorporate Dallas temperature sensors into your own Arduino builds.
Your kids will think you’re a wiz when they’re able to recreate their own Deathly Hallows with these unique dueling wands.

Still Rockin’ the microSD Card
took a while, but paper punch cards finally bit the dust. Good old RS-232 is in the rocking chair, as well.These days, thanks to the microcontroller industries’ hardware refinements and ready-to-run library code, putting a USB portal online is just as easy as building an RS-232 interface.
