Transformation: GP39-2 From Shiny Brass to Grimy Green

[nachoman]

I think Laurie is quite active on the Yahoo HOn3 group. 9.99 for 50 white LEDs is quite cheap. 5 years ago, you would have paid a buck a piece. 5 years from now, you may get 50 for 3.99. Electronics technology is fascinating. When my dad graduated college and got his first job, he bought his first Texas Instruments calculator. He probably gave 300 dollars for it in the early 1970s. One time, he was joking with his coworkers that some day calculators would be sold in the checkout aisle for less than 10 bucks. When I was first experimenting with electronics as a teenager (about 1990), there were only green, yellow, and red LEDs. I always thought it would be great if someone could figure out how to make other colors, and a few years later they did. They barely use any electricity, don't get hot, and last forever. My prediction is within 5 years, LED household lightbulbs will be commonplace - saving a ton on domestic electricity consumption.
