• A Notable 2m Radio Contact
  For the 2019 CQ Worldwide VHF Contest, I did a modest effort on 6 meters and 2 meters using mostly SSB and FT8. I operated from our cabin (DM78av). We had some good sporadic-E propagation on 6m which enabled some long-distance contacts to the east. Then I noticed that 2 meters was also open so … Continue reading A Notable 2m Radio Contact →

View in browser THE CARE AND FEEDING OF ANALOG METERS In a digital world, there are still quite a few uses for an analog meter, but these beasts require special TLC. Though just about every experimenter will likely have digital meters on their benches, many do still keep an analog meter around since there are some jobs where these devices can perform better than their digital counterparts. Keeping these analog devices in good repair requires a bit of care. Take Care Now! This Changed Everything – Complete Solutions for One Price Save up to $18,000 on full-solution instruments from Rohde & Schwarz, including oscilloscopes, spectrum analyzers, and power supplies. These instruments come fully loaded with all the bandwidth, channels, memory, spectrum measurements, and signal generation you’ll ever need. Take advantage of this industry first, now through June 30. View Solutions & Pricing Advertisement REPAIRING CIRCUIT BOARDS Repairing any kind of PCB can seem intimidating, but a methodical approach helps in finding and fixing problems quickly. Anyone interested in electronics is bound to encounter a dead board or two, whether it’s their own or someone needing help. What’s the best approach when confronted with a PCB that doesn’t do what it’s supposed to do? Here are several methodical steps to take that range from simplistic to advanced. Read It Now! BUILD THE DIGITAL IMPRESSIONIST Create simple impressionist-style light “paintings” that change over time. Using a PIC16F887 microcontroller to drive eight channels of LEDs, the Digital Impressionist is a fun and interesting project that can spruce up any room in the house with ever-changing colors on an electronic canvas. Build It Now! REPLACING THE 555 WITH A PIC — A DIGITAL ANALOG — PART 3 This third article discusses the less complex audio oscillator circuits from 555 Timer IC Circuits by Forrest Mims. More experiments using PIC processors in the typical role of a 555 timer. This third article in a recurring series examines several of the circuits from 555 Timer IC Circuits by Forrest Mims, which are simple astable multivibrators. Read It Now!

View in browser CIRCUIT SIMULATION MADE EASY Learn a simple numerical method that is intuitive and solves many complex circuit problems with just a few lines of code. After reading the May-June 2018 NV article on Ohm’s law, I thought a follow-up article that goes a little deeper might be in order. Specifically, how Ohm’s Law together with a computer and a couple of tricks can be used to calculate the time dependence of much more complex circuits involving not just resistors but capacitors, inductors, op-amps … you name it! In this article, I’ll describe a simple numerical method that is intuitive and solves many complex problems with just a few lines of code. No simulator needed! Read It Now! THE ARDUINO GRAPHICS INTERFACE Part 2 — Software Concepts and Support Library In Part 1, we described the background and hardware build of the Arduino Graphics Interface (AGI). With this platform, you can turn an analog oscilloscope into a very high resolution graphics display device. This time, we’ll complete the project by describing the details of the XYscope: the software libraries and sample code that make the AGI hardware easy to use and integrate into any graphics display application. Build It Now! REPLACING THE 555 WITH A PIC — A DIGITAL ANALOG — PART 2 Inspired by Forrest Mims and his Mini-Notebook series, we are detailing the emulation of a 555 or 556 using a PIC in several different circuits in our own set of articles. In this second of five articles, I’ll review the circuits in the 555 Timer IC Circuits by Forrest Mims which use the 555 specifically as a simple one-shot (circuits 1, 3, 4, 5, 8, 9, 10, and 13), as well as discuss how to use the PIC 555 replacement (see Part 1) in the same applications. I have also included three dedicated one-shot programs that can be modified as required for your own projects. Read It Now! FOUR-POSITION HF ANTENNA SWITCH WITH PC CONTROL Make your ham life easier with a PC controlled antenna switch. Meet the SW-4U: A four-position ham radio antenna switch with PC control via a USB connection. The switch is controlled by an application program running on the PC that allows you to select any of four antennas, ground all for safety, and to power the switch on and off. Make Life Easier Now!

• “BEST REGARDSES” AND “BEST REGARDS’S”
  “Best regardses” and “Best regards’s” That’s silly, of course. We who speak and write in the English language know that you should not pluralize a word that is already in its plural form. “Best regards” means, “I wish you the best of regards.” It is implied that there is more than one regard. Perhaps there […]

View in browser LIGHT BULBS, LEDs, AND CIRCUIT JUNCTIONS Take a look at some specific electrical properties of both light bulbs and LEDs, and use them to discuss junctions in DC circuits. I was working on a project with different colored LEDs. Putting them in parallel across a power supply was easy but puzzling, because the different colored LEDs simply wouldn’t light properly. I now know why, and it appears that driving (different colored) LEDs in parallel directly from a DC power supply was not a good idea. This article will explain why. Read It Now! THE ARDUINO GRAPHICS INTERFACE Part 1 — Design Concepts and Hardware Fabrication Turn an Arduino Due and a leftover analog oscilloscope into a high resolution computer graphics display and gain valuable insights into computer graphics, digital-to-analog conversion (ADC), and advanced Direct Memory Access (DMA) hardware and software techniques. Build It Now! REPLACING THE 555 WITH A PIC — A DIGITAL ANALOG — PART 1 Learn how to emulate a 555 or 556 using a PIC microcontroller — with no special programming required. Inspired by Forrest Mims and his Mini-Notebook series, we’ll detail the emulation of a 555 or 556 using a PIC in several different circuits. The particular implementation this time covers both monostable and astable modes, and the PIC does not have to be reprogrammed in any way. Read It Now! BUILD A CONTINUITY TESTER Go old-school with this custom design of a continuity tester. During a recent vacation, I challenged myself to come up with a design for a continuity tester that suits my particular testing requirements. Most of the time, I go straight for a microcontroller, but this time I decided to use only non-programmable components. I also decided to use only through hole components to make soldering easier.
