View in browser YOU DON’T HAVE TO BE AN ENGINEER TO DESIGN YOUR OWN ELECTRONIC CIRCUITS Do your own designs with a little direction. Most of you have at one time or another thought about designing your own electronics. The thing stopping many of you is the fact that you realize you’re not a “real” graduate engineer. Well, so what? You don’t have to have an EE degree to design. You can do your own design with a little direction. Here’s my approach to it, so you can give it a try. Read It Now! Ask an Engineer Learn why engineers use Rohde & Schwarz instruments in their labs. See Reviews Advertisement MICROCHIP TECHNOLOGY: CONCEPTS, PRODUCTS, COMPANY Everything you want to know about microchips, but were afraid to ask. A microchip is a synonym for chip, which is common slang for "integrated circuit." Why the term "chip?" Because when you slice a wafer of integrated circuits into their individual parts, they look like, well, chips. There are all kinds of chips, and the major ones are outlined here. Read It Now! MONITOR MOTION FROM A USB WEBCAM Take a look at how this highly configurable and stable monitoring system works. This system monitors motion from a USB webcam on a Raspberry Pi 3 using the OpenCV API. Once movement is detected by the system, it takes a picture of what set the motion detection software off and emails that picture to you. It also affords you the ability to remotely view the webcam from an Android application from anywhere in the world at any time. Build One Now! BUILD AN AUDIO LOOP SYSTEM Create a Telecoil installation for your home. The last time I had my hearing aids serviced, I discovered that the devices included a T-mode operational feature. The T-mode (or Telecoil) setting allows you to receive audio signals fed to an induction loop, which is just a wire loop laid on the floor around the perimeter of the desired area. Induction loops can be found in places such as concert halls, movie theaters, auditoriums, churches, banks, and public buildings where PA announcements are common. I decided to build an installation for my home. Here’s how it went. Hear About It Now!

Even though CW is no longer a required component of amateur radio license tests, it’s still a practical and fun skill to learn.

All you need is the discipline to spend 10-20 minutes/day practicing and you’ll be sending and receiving CW before you know it. Read It Now!

I’m a sucker for cheap electronic parts, especially wireless stuff. Just recently, a catalog from one of my favorite parts distributors (All Electronics) came in the mail and was promoting some wireless modules: a transmitter (TX) and a receiver (RX) for just a few bucks each. I ordered immediately. Now that I had these wireless modules, I wasn’t sure what to do with them. I had no plan or goal in mind. So, I decided I would just experiment for fun.

THE RETRO PIC SINGLE-BOARD COMPUTER Put some of your historic chips to work in a new “computer” system with a PIC acting as the CPU. Over the years, I have accumulated a bunch of chips from before the era of true PCs when computers with names like Altair, KIM-1, and Cosmac ELF were popular. I’ve been looking for a way to use them in new projects, so I designed a system around a 40-pin PIC16F887. I figured this would put some of my historic chips to work and be a great learning tool for understanding how a microcomputer works. Read It Now!

For short-range and in-the-home wireless, you don’t need much more antenna than what is supplied with your router, dongle, or laptop.

Once you start thinking about a longer link such as to supply Internet connectivity at a temporary site, improve marginal mobile phone service, or set up your company’s new repeater system, you’ll need outdoor antennas And something to put them on. This may not be a workbench topic but it’s certainly a part of wireless!

When I was in junior college, I did an experiment in a physics class that I have never forgotten. It was the classic falling body experiment to measure the acceleration of gravity; 9.81 meters/sec2. I loved carefully adjusting the apparatus and meticulously taking the data, trying to get a result that was as close as possible to the established value.
