Orginally licensed in 1964 as WN9SSN then WA9SSN in 1965. While in the army in Germany during the early 70's worked QRP as DA1SC. Let my license expire while sometime between being stationed in Thailand and back to Germany. Relicensed as KE4HMP when I moved to Georgia in the mid 1980s, but because of job did not have time to get back into the hobby. Just retired and thought I would give it a try again. Now that I am not traveling and working on electronics 5 days a week this might become a nice hobby again.
My main interest is designing and building equipment. Since I retired, I have been mostly building test equipment based on the Arduino family of micro-controllers. This is the platform I wish I had 35 years ago when I was working in engineering. The closest thing I had was a single board controller uising a Z80, 4K of RAM, 24K ROM and 24 IO pins. It was about 1 ft. square and cost around $250. Then add over $1000 for Compiler, Assembler, Linker software, plus a couple hundred for an EPROM burner. Of course there was not much in the way of software available for instrumentation and control applications, so you pretty much had to write everything yourself. Now it is as small as a large postage stamp, costs $3,the software is free, and there is a huge amount of application and driver software available.
I have been documenting some of my projects on my blog kv4qb.blogspot.com. Stop by and see what I have been up to.
