Projects

  • Build Your Own Magnetometer by William Baird
    One of the neatest gadgets made possible by modern IC technology is the magnetometer. For less than $25, you can construct a fun and durable tool to measure magnetic fields (static or varying) produced by currents, permanent magnets, pieces of iron, or the Earth itself.
  • Talking T-Shirt Responds to Your Touch by Gordon McComb
    Make this interactive costume for exciting Halloween thrills and chills.
  • A High Voltage Halloween by Walter Noon
    A powerful Van de Graaff generator can make for some hair-raising Halloween fun!

Columns

  • Techknowledgey by Jeff Eckert
    Events, Advances, and News
    Read about a virus generator being developed, a radio scrambler/descrambler, if Panasonic is sinking ... plus some other stuff you’ll want to know about.
  • Near Space by L. Paul Verhage
    Balloonsats and Attitudes Toward Science
    began my investigation by becoming acquainted with what other people had to say about STEM in today’s world. Three issues made the greatest impression on me: the aging science and engineering workforce; the increasing competition from overseas; and the increasing importance of STEM in everyday life.
  • Q&A by Russell Kincaid
    Reader Questions Answered Here
    A driveway system hack, fan speed control, and an LED array driver are some of the topics discussed this time.
  • The Spin Zone by Jon Williams
    Show Time!
    Those that know me well know that this is my favorite time of year. Halloween is right around the corner and that's followed up by the Christmas "season" — a couple months where prop displays flourish and indoor/outdoor decorators feverishly work to eclipse their creations of years past. I love this season.
  • Smiley’s Workshop by Joe Pardue
    Fritzing With the Arduino — Part 2
    This month, we will see how to take that breadboard prototype and generate a schematic design. Then — still using Fritzing — we’ll convert it into a printed circuit board (PCB) layout that we will have manufactured for us by SparkFun’s BatchPCB service.
