    My expanding collection of projects as I experiment with electronics, radios, and networks.

    My interests span across many different areas and the number of my ongoing projects continue to expand.  Many of these articles are created as a reference as I attempt to figure things out, work on new ideas, and expand my knowledge.  In my home electronics lab, I work on many things such as raspberry pi, arduinos, electronic kit building, various types of radios including ham radio, computers, programming, and network security.  Outside in the garage workshop I enjoy woodworking, fixing and breaking things, locksmithing, and generally working with tools.  Just like my life, this site is every changing with new ideas and projects.
