If you are an electronics hobbyist or student you are likely to already be familiar with the textbook The Art of Electronics. The Art of Electronics is the current academic standard in teaching the principals of electronics at a college level. Last year they added this hands-on lab course. What I found most useful is that the lab book can actually stand on it’s own. You do not have to have or have-read the textbook.

This lab course book seems to have been written with self-study in mind. In fact, the lab course even explains basic principals. Through the book you will have many hands-on labs with full parts lists. Not only does the book cover principals, but it includes techniques and troubleshooting. You learn how to do diagnostics with oscilloscopes, multi-meters, and other tools.

I’d say this book is a must have for beginners/students and will easily be useful and fun for up to intermediate hobbyists. Advanced and Expert hobbyists may want this book for teaching or simply as a review reference.

Review: BL-5L Extended 3800mAh 7.4V Li ion Battery



First off, the purpose of my purchase was so that I would have some extra battery power for my new BF-F9V2+ for LEO field operations. I’m planning on using high power which is 8W.

I picked this battery up on Amazon for about $15.00.

The battery fits my Baofeng UV-5R and BF-F9V2+.

On the BF it doesn’t quite lock in place. I had to stand it up and apply some light pressure to the top of the radio to get a secure click. This is the only reason I have not given it 5 stars.

The build quality is solid and cosmetically matches up great with both the UV-5R and BF-F9V2+.

I like being able to plug a car charger into it. Although I wouldn’t recommend trying to run it while charging. I tried and the battery pack heated up a bit. Fortunately I was just testing so didn’t leave it sitting for a long time. While charging I’ll just use my spare, stock battery pack.

In closing, a word of caution. My first purchase was an OEM version of this battery pack under the Tera name brand. I am not totally convinced that they are made in the same factory. I had a number of problems with the Tera. First, I left it to charge for two full days and the light was still red on the charger. I was using the stock UV-5R charger. When I tried plugging in the car charger, the battery pack immediately started getting hot. Lastly, it did not fit the BF-F9V2+. The BF-F9V2+ and UV-5R accessories are supposed to be interchangeable. There are actually YouTube videos on how to modify the case to make it fit. It is totally within the realm of possibility that I just got a bad production run battery. However, based on my current experience, I would stay away from the Tera labeled battery pack. Stick with the Baofeng.

Tutorial: Get Google Earth Pro for Free

I’ve been using Google Earth Pro for years at work. Since I do a lot of outside fiber plant and WiFi work I like using the overlays feature to drop site plans, heat maps, and LiDAR data into an easy to use and share platform.

It’s great looking up coordinates and measuring distances. I have often been told that everything Google Earth can do, Google Maps can do as well. Well in that case I have pointed out that they are not using Google Earth to its full potential. Once you start using Google Earth Pro, you will see the differences, particularly, the ability to share KMZ files.

Well, in case you weren’t aware, Google has allowed free licensing for Google Earth Pro. Just follow the link below.

Here are the steps to obtaining the Google Earth Pro software and how to set it up. Continue reading

Tech Talk – Coax Wrap – Self Adhering



I was strolling threw the HRO online store when I came across an ad for coax wrap and thought I’d share some information with you.

I swear by this stuff. As a fiber and cabling technician with 20+ years experience in the field I can attest to you that self adhering wrap is the way to go for water proof sealing of connectors. Continue reading
