Fake TV - Burglar Deterrent I was shopping around on Amazon the other day and came across a product that I thought was genius. It is called Fake TV and it acts as a burglar deterrent while you are away from the house. At night, the Fake TV turns on and uses a series of LEDs to project random colors that looks as though someone is inside watching TV when viewed through curtains or shades. There are some videos of it in action on YouTube and I have to say it really does look like someone is inside watching TV. This should scare off the large majority of petty thieves that are just looking for the quick opportunity. If someone is casing your house, this probably isn't going to help you though.

Carl Sagan Collection Since its creation in 1976, the Committee for Skeptical Inquiry (formerly known as CSICOP - the Committee for the Scientific Investigation of Claims of the Paranormal) has been honored by its association with founding member Carl Sagan, David Duncan Professor of Astronomy and Space Sciences and the Director of the Laboratory for Planetary Studies at Cornell University, Pulitzer Prize-winning author, Peabody-winning television producer, and recipient of the National Academy of Science’s highest honor, the Public Welfare Medal. Many of us first came to science and skepticism by way of Sagan’s PBS series, COSMOS, but his dedication to skeptical inquiry began long before we saw him on television. Early efforts to inform the public about science, pseudoscience, and the difference between them began in the late 1960s, and from them Sagan created one of the key principles of the skeptical movement: extraordinary claims require extraordinary evidence.

Repel Mosquitos, Dogs, & Annoying Friends with High-Frequency Tones on Android « Android Gadget Hacks Repel Mosquitos, Dogs, & Annoying Friends with High-Frequency Tones on Android There are few sounds that actually make me cringe whenever I hear them: silverware scraping on a plate, nails scratching on a chalkboard, and piercing high-frequency tones. While the former two terrors require some physical hardware, sending out high-frequency sounds is as easy as downloading an app. Of course, since high-frequency sounds are terrible things to hear, this app is great for classroom and office pranks, or quite possibly fending off dogs and bugs. Try this at your own peril (I suggest using earbuds or earplugs).
