  • The Trainsaver Digital Electronic Controller by Vern Graner
    The TrainSaver is a device that reduces wear and tear on model train locomotives used in commercial environments. The TrainSaver maximizes the life of the engine by only running the train on timed intervals, and only when people are present to view the train's performance. This reduces the cost of ownership of the train system by increasing the life of the engine. The device also adds synchronized sound effects to enhance the train's visibility to the audience ...
  • RADAR And Electronic Warefare Fundamentals by Gerard Fonte
    Radar and Electronic Warfare (EW) are usually thought of as being very complicated and very secret. And while this is true for specific designs and detailed theory, many of the basic principles are straightforward and easy to understand. This article will present some of the fundamental concepts of radar and show how EW develops from that.
  • Choosing A Heatsink by H. Ward Silver
    Let's face it — if this article was titled, “Thermal Analysis,” you might put off reading it! But choosing a heatsink? Everybody understands what that’s all about, right? To make that choice, you have to do a little thermal analysis (gotcha!), but if you can do Ohm’s Law, you already know how!
  • Understanding Digital Logic ICs — Part 1 by Ray Marston
    Ray Marston explains digital logic IC fundamentals in this opening episode of a four-part, introductory mini-series.


  • Long-Range Stereo Microphones by J. Ronald Eyton
    Friends, birders, electronics enthusiasts, lend me your ears so that you may listen to faraway sounds using these easily built long-range stereo microphones.
  • Integrating the CMUcam — Part 2 by Michael Simpson
    A while back, I was researching sensors for a project I was working on when I came across a little device called a CMUcam. The CMUcam is a low-cost vision sensor developed by Carnegie Mellon University ( The CMUcam has both an RS232 level interface, as well as a TTL level serial interface so you can connect it to your favorite microcontroller or directly to a PC ...


  • Q&A by TJ Byers
    Reader Questions Answered Here
    In this column, I answer questions about all aspects of electronics, including computer hardware, software, circuits, electronic theory, troubleshooting, and anything else of interest to the hobbyist.
  • Getting Started With PICS by Chuck Hellebuyck
    Developing With A PIC Bootloader
    If you’ve been a regular reader of this column and have started to actually program PICs, you are probably tired of moving the PIC from programmer to project and back again every time you make a change. It not only damages pins, but can sometimes cause confusion if the PIC is put in the board backwards or even shifted by one pin. This is why I like to develop with a bootloader and it’s one of the most difficult items to explain to a beginner ...
  • Personal Robotics by Phil Davis
    Design A Mini Sumo — Part 1
    Last spring, our robotics club scheduled a Mini Sumo competition for the summer of 2005. Of course, no one had a Mini Sumo robot, so a mad frenzy of ideas, concepts, and parts ensued.

  • Stamp Applications by Jon Williams
    A Tale Of Two Props
    After spending a few months with Parallax's newest controller — the Propeller chip — why not step back in time a bit (13 years!) and work with the oldest, the venerable BS1 — the controller that started it all for Parallax.
  • Near Space by L. Paul Verhage
    The Near Space Geiger Counter Telescope — Part 2
    his month’s column wraps up the Geiger Counter Telescope (GCT) and discusses a transistor experiment I performed. This article covers the GCT’s field-of-view, a ground test of the GCT, and flight software that operates the GCT. There is a small note to clear up the RM-60 instructions in chapter eight of my near space book at the Parallax website and a transistor experiment which includes a competition for readers.
  • The Design Cycle by Peter Best
    The Easiest Internet Protocol Of All
    RS-232-based serial ports are great data donkeys until you need to move data on an Ethernet LAN or throw it out onto the Internet. Most of the networking email questions I field from Nuts & Volts’ readers concern moving their data transfers away from traditional RS-232 cables and on to an Ethernet LAN or the Internet ...
