I am a developer of hardware and software. My first computer (1984) was a Timex-Sinclair 2068 and I still have it and it still works. Currently, I am busy buying and developing for Parallax Propellers, Arduino based boards (MegaADK, Netduino 3 and Galileo 2) and Raspberry Pi3+. I use them for data collection and some of that involves Software Defined Radio. I also write and study code for white hat hacking -- I have a Kali Linux based system with a substantial set of 2.4 and 5Ghz radios.
I also enjoy astrophotography, medium power rocketry and UAVs.
