Home built Electronic Projects (Homebrew)I have built several kits and have been collecting parts (junk as my wife calls it) and have several projects in mind. The most ambitious of these would be to build a HF SSB/CW multiband radio from scratch. I am a lot better at collecting parts that implementing the construction of these projects. Some of the other projects I am interested in building are a spectrum analyzer, weather monitoring equipment such as a wind speed indicator and a self emptying rain gage, driveway alarm, and computer monitoring and data acquisition on some of the above. Spectrum Analyzer -- I have seen several articles and web pages on building this project. There was a series of articles in August and September 1998 QST and also a Science Workshop website selling a book and parts to build an analyzer. HF Radio Transceiver -- There is a good book showing complete plans with circuit boards available from Kanga. This book is "Build Your Own Intelligent Radio Transceiver" by Randy L. Henderson. In the meantime, I have put together a K2 Kit from Elecraft. It went together with a minimum of problems. It includes a noise blanker option as well as the SSB module. This radio covers 80 through 10 meters. I will hopefully get the finishing touches on it and get it on the air during the 2000 holiday season. I hope to use if for PSK31 and RTTY. I am also almost finished with a VE2EMM 32 LED Doppler direction finder. I bought the boards and the programmed PIC from Far Circuits. The other parts were ordered from Digikey and Mouser. Hope the dipole antenna array I plan on putting together doesn't look too bad on my little pickup. The driveway alarm I will attempt with a Honeywell magnetic sensor. It looks possible from the application notes. If I get it together and it works, I will post the results here.
