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! Read It Now! FIX UP THAT OLD RADIO! Part 2 wraps up our restoration.

THE SECRET LIFE OF A WIRE A perfect wire should conduct a signal without adding noise, attenuation, or distortion. However, this isn’t the case! A perfect wire should conduct a signal without adding noise, attenuation, or distortion. Whatever is electrically happening at one end of the wire should be happening at the other end exactly in the same form, no matter what the current, voltage, frequency, surroundings, or temperature.

View in browser HOW PHASED ARRAY ANTENNAS WORK Introductory tutorial on a special antenna type you need to know about. Phased arrays have been used for years in military radars for long range detection of missiles. They’re also widely used in military and commercial aircraft radars and some satellites. These phased arrays are expensive, but today thanks to new technology and higher frequencies, phased arrays are smaller and more affordable making them practical for new wireless devices. This article is an introductory tutorial on this special antenna type you need to know about. Read It Now! Take your electronic skills to the next level with Dr.Duino! A complete learning and rapid prototyping system. Perfect for the beginner or advanced user. It’s like an entire electronics lab in your pocket! Click here to learn more! Advertisement Read the review on the Dr. Duino Explorer here. CALCULATORS AS COPROCESSORS Turn a TI calculator into a computing machine. Connect Texas Instruments calculators to Arduinos to extend this open source prototyping platform’s computing power for math functions and to make graphic capabilities easier to implement. Read It Now! ADD SWEEP FUNCTION TO YOUR RF SIGNAL GENERATOR Add a sweep function to my original RF generator build or any unit that is based on varactor diode tuning. After I had designed an RF generator, I started to toy with the idea of adding a sweep function to it. The circuitry is quite economical to build, and draws its power through a short cable that plugs into a connector at the rear of the RF generator. Although this unit was created for use on my original generator design, the basic architecture can be modified for use with commercial RF generators that are based on varactor diode tuning. Add It Now! FIX UP THAT OLD RADIO! It’s fun and easy to bring vintage radios back to life! Follow along as a 1937 DeWald radio is restored. Even though they’re ancient by today’s standards, old tube radios can almost always be brought back to life, and there’s still plenty of broadcasts out there for them to receive! Not to mention, they just look so classy and have a presence few modern electronics can match. Fix It Now!
