Lifelong technologist and long career in computer and communications technology during through hole era. Equal parts, hardware, software, and limited embedded systems product development. Now, I am re-orienting my personal workbench to surface mount circuits and PCB component level troubleshooting and repair. I have mostly adapted to the very small at this point. Thankfully electronics theory does care about size. Everything interests me! I am a very curious person and feel the need to understand how things work.
