KG5AXF.net is Under Construction!

I am in the process of turning up one of my domains, kg5axf.net, on a virtual private server (VPS). I wanted someplace to be able to publish my weather station data and a few other projects. I currently have a Raspberry Pi 2+ running Raspbian that is using WeeWx to collect data from an AcuRite personal weather station (PWS). WeeWx has a built in web server that publishes the weather station data. It also has the capability to publish to an external server. I am working on enabling that functionality which will be served by the VPS using the domain wx.kg5axf.net and ktxhoust1920.kg5axf.net. KTXHOUST1920 is the Wunderground ID for my PWS.

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.

Software: CadSoft EAGLE

I’ve used Microsoft Visio for many years to create flow charts, diagrams, maps, etc and started to use it to design circuits. I quickly discovered that Visio has it’s limitations. Off I went to find an application that I could use to design my circuits and circuit boards. Everything I found was very expensive, considering I don’t like to pay for any software these days, or if it was free it didn’t have the functionality that I liked.

Enter CadSoft EAGLE. Continue reading

Project Gear: Motorola GM300

I just received a Motorola GM300 that I purchased on EBay. It’s very clean and powers up. Just waiting for an adapter for the antenna connector. This is a project radio. I’m going to use it for EchoLink, AllStar, and APRS. I’ll likely find other uses for it as well. It was only $40.00, so couldn’t pass it up. I’m going to make a pigtail for the options connector to plug into a breadboard. I also received an Arduino and the new Raspberry Pi 3 thanks to Amazon, so I’ll be coming up with ways to connect these devices.

Review: The Easy Digi

Well, this is more of a preview than a review. Along with a couple of Raspberry Pi’s I ordered an assembled Easy Digi. The Easy Digi is an external sound card board. The one that I ordered is coming fully assembled. I want to see a working one before I experiment with the actual kit. You can find the kit on eBay for under $10.00 and fully assembled, tested, and with cables, for under $40.00. This is a huge price difference, $80.00 is the next cheapest one, from other units.
