This looks like an interesting project to undertake.
“Infrared Light Against Surveillance Cameras” is an easy to build device that protects you from cameras in public spaces. The focus is to amplify the interaction between “machines” (or light sources) that have been built as surveillance devices.
They may look like pin-sharp photographs - but these amazing pictures are actually drawings created with the humble ballpoint pen.
The stunning pictures, measuring up to 10ft high, were drawn by a rising star of the art world, Juan Francisco Casas.
Casas said: “I guess it started off as a joke, to try and make something so realistic that people would think is a photo.
“I also wanted to create it with something that everyone has - a Biro. I don’t think it has ever been done before.
“For me it’s not that different from painting. I was trying to show that it doesn’t matter what material you use, it’s what you do with it.”
Casas only uses blue Bics and can get through several to make one drawing.
The only drawback is that he can’t erase any errors. He said: “Mistakes are the main problem. It’s better if I make them at the beginning.”
This sounds like a pretty good idea. Although the backlash from incorrect use of this equipment could be bad.
A service station in Essex has fitted traffic lights and a stinger device to deter people driving away without paying after filling up with fuel.
The Drivestop device can be activated by staff at the exit and entrance to puncture the tyres of any suspect car.
Warning signs and traffic lights alert motorists to the device.
Ray Holloway, from the Petrol Retailers Association (PRA), said the special stinger is a necessity if businesses are to survive because “drive-aways” can hit garages hard.
The world’s first commercial cargo ship partially powered by a giant kite is setting sail from Germany to Venezuela.
The designers of the MS Beluga Skysails say the computer-controlled kite, measuring 160sq m (1,722sq ft), could cut fuel consumption by as much as 20%.They also hope the state-of-the-art kite will help reduce carbon dioxide emissions, as it tugs the ship.
Fuel burnt by ships accounts for 4% of global CO2 emissions - twice as much as the aviation industry produces.
Here’s a visible shock wave that’s been produced by destroying a weapons cache in Iraq.
