View in browser IMPEDANCE MATCHING Impedance matching is not mysterious, it’s really just about controlling reflections in transmission lines. When RF energy travels in a transmission line and encounters a load or different type of line, the resulting reflections create standing waves of voltage and current, just as water waves do when they encounter an obstruction. This can create problems with digital signals and can result in extra losses. However, there are several techniques for dealing with these reflections. Read It Now! CALCULATING CURRENT LIMITING RESISTOR VALUES FOR LED CIRCUITS The key to maximizing LED life is limiting the current that runs through it. This is frequently done with a simple resistor whose value is calculated using Ohm’s Law. This article reviews how to apply Ohm’s Law to single and clustered LED circuits. Read It Now! BUILDING A PROGRAMMABLE THERMOSTAT WITH A NEXTION LCD DISPLAY Customizing a thermostat for a simple forced air heating/cooling system. I realized there were several things I wanted to learn about thermostats. I determined to do some studying and then build one of my own design. Here’s what I did. Build It Now!

I noticed an amplifier on eBay that was out of a 1952 Rock-ola 1436 jukebox, and just had to have it. It was essentially a dead carcass, so I decided to restore the amplifier and make it able to stand alone. I wanted to make the restored amplifier as authentic as possible to the 1952 version.

View in browser VACUUM TUBES At the ripe old age of 100+ years old, is the venerable vacuum tube still relevant in modern designs? For audiophiles, musicians, and ham radio operators, the soft glow of the vacuum tube filament is not only an indication of function, but a nostalgic trigger for memories of simpler times. Though they may have been outpaced by tiny transistors and integrated circuits, these workhorses still may have something to offer in many modern devices. Read It Now! BUILD AN INEXPENSIVE MAGNETOMETER Build a Hall-effect based magnetometer. This article describes a Hall-effect based magnetometer that uses an inexpensive analog Hall-effect sensor, an Arduino, and LCD. The linearity of the magnetometer is surprisingly good when compared against a commercial magnetometer. This unit can be operated manually or make measurements under computer control, so we’ll use our magnetometer in a computer-controlled setup to measure the BH-curve of small sample of magnetic material.

Competency — a measure of someone’s skills, knowledge, and attitudes in a domain — is a term usually associated with work and human resource departments. However, the concept of competency also has merit in the avocation of electronics. But what constitutes competency, and why should you aspire to greater competency? Read It Now!

It seems that the utility of analog mathematical circuits has been shunted aside. However, there are still useful and important applications for analog mathematics in today’s digital world. In fact, the marriage between analog computing and microprocessors (µCs) can be remarkably efficient. Read It Now! BUILD THE NIXIESTAR CLOCK Construct this elegant and intricate timepiece. The NixieStar clock is the second timepiece kit I’ve developed. My aim was to have a kit that’s reasonably easy to build with intermediate soldering skills (i.e., minimal SMD components).
