I love books, and I love the fact that technology is becoming increasingly easy to get books digitized and distributed online. Several years ago I got a copy of Johnson's Natural History that I'd love to have digitized, but as yet haven't located anyone whose willing to do it for me. But today, I found a couple of interesting links that suggest with a modest investment, I could make a book scanner of my own. Here are some links to some projects that might be useful:
G3XBM pointed out silent key KL7R's modification of a Heathkit HW-8 to do double sideband voice. It looks pretty straightforward, and would be an interesting modification.
