A radio that doesn't need a battery or plug? In the "Build Your Own Crystal Radio" electricity and #electronics #science project students build a working crystal radio and investigate how to improve it. A convenient project kit is available to do this science project!

Hack Attack: Turn your $60 router into a $600 router Of all the great DIY projects at this year's Maker Faire, the one project that really caught my eye involved converting a regular old $60 router into a powerful, highly configurable $600 router. The router has an interesting history, but all you really need to know is that the special sauce lies in embedding Linux in your router. I found this project especially attractive because: 1) It's easy, and 2) it's totally free.
"Crystal Radio: A Science Kit for Student Electronics": Build a crystal radio and then tune in an AM radio station--without batteries. An improved crystal radio kit and an updated procedure makes this a great choice for an assigned #science project or just for hands-on #electronics fun!

Tesla's Spirit Radio uses a simple crystal radio circuit connected to a computer sound-in jack to generate spooky sounds from all kinds of electromagnetic sources"My first observations positively terrified me as there was present in them something mysterious, not to say supernatural, and I was alone in my laboratory at night." - Nikola Tesla 1901
