One place to checkout this new phenomena is Make Magazine. Here you’ll find folks like Diana Eng, KC2UHB, who posted a piece on building your own homemade yagi antenna and describes how to use it to listen to orbiting satellites (AO-51, 30 and 27). Here’s a link to Diana at the QRP convention in Boston.
Here’s another young builder.
StacyD is a “young female computer engineer with a passion for DIY”.
Here’s a link to her blog site where she shows how to take a set of cheap headphones and for less than $50 of parts turn them into headphones that rival the mainstream manufacturer’s top-of-the-line $500 offerings.
BTW read the comments under her article. They go on and on and on 🙂
If either of these two young people were my daughters I’d be pretty darn proud of them.
Speaking as an old guy…seems to me the kids are all right 🙂
