Hi Bill! This Bob Schubert, KC4FNE in Blacksburg Virginia just wanting to say hello and taking the opportunity to say "Thanks" for the SolderSmoke Series. I have to let you know your podcast accompanies me as I do my early morning exercise regime. Before SolderSmoke, I would begrudgingly get out on the track every other day. Now I'm out there just about every morning listening to a new episode. I'm not sure what I will do once I exhaust all of the episodes? Normally I would cover my obligatory 2 miles in 45 minutes, now I'm looking for excuses to stay on the track so as to complete a one-hour or so episode. When I'm listening to it in the car, I find myself circling the block just so I can finish a podcast. It has also prompted me to purchase the SolderSmoke book. I'm thoroughly enjoying the book as we seemed to have both grown up close to the same timeframe and our early lives led as "geeks." If you interetsted in what an "old geek" is up to now, point your browser to http://www.lumenhaus.com/ This is a solar powered house done by a team of architecture and engineering students/faculty I was involved with. If you ever find your way to Blacksburg and are interetsed in our Lumenhaus, I would be happy to provide a tour.
I've included a photograph of me taken at Orange County High School in the mid-60's with a science fair experiment "Talking on a Light Beam." While not quite in the 478THz range of the high-power LEDs it was up there! While modulating the filament on a flashlight I would be hard-pressed to go 95ft much less 95 miles.
Best, Bob Schubert KC4FNE
