The Silicon Graybeard

In the World of the High Tech Redneck, the Graybeard is the old guy who earned his gray by making all the mistakes, and tries to keep the young 'uns from repeating them. Silicon Graybeard is my term for an old hardware engineer; a circuit designer. The focus of this blog is on doing things, from radio to home machine shops and making all kinds of things, along with comments from a retired radio engineer, that run from tech, science or space news to economics; from firearms to world events.
