  • Tools of the Trade by Chris Savage
    Whether you’re a professional or hobbyist (or both!), having the right equipment to accomplish what you’re doing makes all the difference in the world. Here’s a look at some of the “must-have” tools for a workbench.


  • Zener Diode Tester by Gordon Hoffman
    It’s very time-consuming to set up a power supply and voltmeter, and then select a series resistor to limit current just to measure the voltage of diodes. The unit described here is a simple two-transistor circuit that needs nothing more than a multimeter to build, test, and use it.
  • Three-Axis Hockey Puck Accelerometer Data Logger by Ron Newton
    Accelerometers can be used in many applications, and this unique device is no exception — especially when it’s combined with our poor man’s seismometer from a previous issue.
  • Toss the Toggle by Jürgen G. Schmidt
    projects be embarrassed by their old-school toggles and slide switches! Upgrade them to the power of push buttons!


  • Q&A by Tim Brown
    Reader Questions Answered Here
    Read about solutions to fix a broken laptop, a VCR that eats tapes, and sound system hum.
  • Personal Robotics by Ron Hackett
    Introducing the RazzPi PCBs
    Learn about two new printed circuit boards you can use in either PICAXE-Pi projects or pure PICAXE applications.
  • The Design Cycle by Fred Eady
    PICs and a Stick Pack Big Computing Power in a Small Package
    The Rapid USB prototyping stick is powered by an enhanced PIC16 microcontroller that can do the work normally relegated to PIC32 silicon. The PIC16F1459 under the USB stick's hood can spout USB lingo at one end and spit RS-232 bits out of the other. No external clock crystal is required to utilize the stick's ADC, comparators, DAC, SPI module, and timers. This installment will show you how to take advantage of the tremendous amount of computation power stuffed into a very small package.
  • Smiley’s Workshop by Joe Pardue
    The Arduino Classroom. Arduino 101/Chapter 10: Sensing Light and Temperature
    Expand what you can sense with an Arduino utilizing light and temperature values as data.
  • Open Communication by Louis E. Frenzel
    Video Monitoring Over the Internet
    Video has gotten so good and cheap lately, everyone seems to be using it. One growing trend in this area has been video monitoring or surveillance, and with the Internet of Things movement, what used to be expensive and tricky is now common place and affordable.
