  • Model Train Switch Control via PC or PIC by Dan Gravatt
    This is a project I wanted to do many years ago when I was spending a lot of time and money on my model railroad. I was disappointed by the big, clunky electrical controllers which operated the track switches, and I wanted to have something smaller and more elegant to do the job. A computer control system would have been ideal, but I never got around to designing one. Many years and several designs later, I have come up with two versions of the control system: one PC-based and one PIC-based ...
  • Audio Spectrum Analyzer by Larry Cicchinelli
    The device described in this article is a configurable audio spectrum analyzer. Many of you have probably seen spectrum analyzers on some higher-end audio equipment, as well as within the GUI of many audio deck programs on your PCs. The function of a spectrum analyzer is to view the frequency components of a signal. One way to state the difference between an oscilloscope and a spectrum analyzer is that with an oscilloscope, you see time domain presentations; with a spectrum analyzer ...

  • Getting Started With PICS by Ron Hackett
    Getting Started with the PICAXE-28X1 Microcontroller
    In essence, the PICAXE-28X1 is like a 28X on steroids. It’s pin-for-pin compatible with the 28X and all the 28X commands will function correctly on a 28X1. In other words, if you have an existing 28X circuit, it will function exactly the same with a 28X1 installed. This is a good thing, because Revolution Education considers the 28X to be obsolete and has discontinued it. Amazingly, the new 28X1 is about the same price as the old 28X ...

    Ten Things You May Not Know About Bluetooth
    Bluetooth is a very familiar name these days if you have a cell phone or laptop. It is a wireless technology that has been around a while and probably can be credited as the start of a whole boat load of short-range wireless technologies. But even if you have heard the name, you may not really know all about it. Here are 10 facts that will update your knowledge of this hot wireless method ...
  • The Design Cycle by Fred Eady
    Up The Logic Food Chain
    I was a totally analog teenager. My interests then were centered on tube-based stereo equipment and tube-based guitar amplifiers. I was fat, dumb, and happily analog until I ran across a copy of the GE Transistor manual in the literature section of a local electronics parts store. I had to have it. Everything “electronic” I was reading about at the time was telling me that vacuum tubes were on their way out and transistors were the thing of the future ...
