The Anti-Paparazzi Purse

By Chris Scott Barr

Being the big-time professional blogger that I am means that I have to deal with being famous. I mean, I can’t hardly walk down the street without getting bombarded by paparazzi. While that may be a slight exaggeration on my part, there are real celebrities out there that have to deal with that sort of thing on a regular basis. There’s really very little you can do to deter those shutter-happy photographers from blinding celebs with their flash. Thankfully technology may soon give them a helpful tool.

This new purse concept is rather simple. It houses a small LED flash that can detect bright sources of light. When it senses a camera flash, it kicks on its own bright flash to compensate. This will then cause the picture to come out with a large white area where the subject should be. It works at 1/125 shutter speed, which should be fast enough to blind cameras shooting at slower speeds for night shots.

Learn Some Basic Circuitry Skills And Create Some Halloween Fun

By Jonathan Kimak

Every so often there comes around a neat little DIY project that can be both fun and educational. If you don’t know much about circuitry, this halloween project might be the thing that finally moves you from gadget user to gadget maker.

The project is to create a light-sensitive jack-o-lantern that turns itself off during the day and comes alive during the night with two glowing LED eyes. All you need is a phototransistor, several transistors and resistors, LEDs and some AA batteries(plus holder). The detailed list can be found at the Evil Mad Scientists website.

Of course, placing something you just made into a goopy mess of a pumpkin might not be too appealing to you. But you can always buy a fake pumpkin from a craft store so that you only have to do this once but get years of use out of it.

United Arab Emirates Goes Big With LEDs

By Jonathan Kimak

What do you do when you’re a tiny little country that makes more money than countries 5 times your size? You spend money on crazy stuff. At least that’s what I think the United Arab Emirates(UAE) are doing. They’ve created skyscrapers with tennis courts on them, are planning to make rotating buildings and now are going for a 33 storey LED display.

The LED display will cover the entire side of a building and will have images viewable 1.5km away. With a display that powerful they’d better be careful what sort of advertisements get played. There could be a lot of traffic accidents from a 330 foot Victoria’s Secret ad.
