From Ars Technica: Apps bar users from Internet, Facebook—and prove surprisingly popular


Fred Stutzman, a post-doctoral fellow at Carnegie Mellon University, has written two programs that allow users to block their own online activities. At first blush, they seem like the answer to a question nobody’s asking. But that has turned out not to be the case.

Stutzman, who researches social media at the university’s Heinz College, has released two apps, Freedom and Anti-Social. Freedom, which banishes a user from his or her Internet connection for up to eight hours, has been downloaded 350,000 times. Anti-Social, which blocks access to social networks like Facebook, has been downloaded by 125,000 users.

More surprising is that Freedom costs $10 and Anti-Social $15 (there are trial versions available with a limited number of uses). To a slightly higher degree than most apps, arguably, you have to really want what they offer. That is, the elimination of distraction.

“Freedom enforces freedom,” the app’s site 1984ishly proclaims. “You’ll need to reboot if you want to get back online while Freedom’s running. The hassle of rebooting means you’re less likely to cheat, and you’ll enjoy enhanced productivity.” The app has been praised by writers from Dave Eggers to Nick Hornby to Zadie Smith.

But Freedom might be too much for those who need online access for their work. “Anti-Social solves this problem,” Stutzman says, by “allowing you to do your online work, while preventing you from accessing top social sites.”

These apps, marketed by his company Eighty Percent Solution, may be indicators of a larger trend. Stutzman seems to think so.

“I think people are starting to pull back and realize how the time we spend online impacts their work, the quality of their work, and their ability to hit goals,” he told Ars.

“Freedom, and Anti-Social, are ways to get this time back—to turn off the constant social obligation of social networks, to better compartmentalize work time and play time. As a technology researcher, I am very positive on the impact of technology, particularly social technologies, on our lives The net effect of a lot of these technologies are positive. However, just because technology can be seamlessly integrated into our lives, does not mean that we need to engage with these technologies at all times. It is important to find space for solitude, concentration, and reflection. I believe a lot of technologies don’t consider this.”

From Popular Science – New Technology, Science News, The Future Now: Rec-Room Cockpit: How One Reader Built His Own Flight Simulator

Clint Fishburne, a regional-airline pilot based in Atlanta, wanted to help his children develop the body movement and muscle memory necessary to fly and land a plane. With the cost of commercial flight simulators starting at $2,800, though, Fishburne, a longtime PopSci reader, decided to make one from scratch. Building the plywood-and-PVC plane, frame and control stick was relatively easy. The challenge was making a platform that could mimic a plane’s motion and that was strong enough to support and move a 75-pound child.

After some experimentation, Fishburne built four custom airbags made of PVC-coated fabric and, to inflate them, connected them to 457-air-watt central vacuum motor. The amount of air in the four bags varies, allowing the simulator to bank or pitch up to 25 degrees on either axis. When the pilot pushes the stick left, a valve increases airflow to the right airbag and vents air from the left. An accelerometer sends spatial-position data to a laptop by USB, and an LCD projector beams the imagery from Microsoft’s Flight Simulator software onto a wall. Fishburne is now trying to commercialize a kit version of his simulator, in part to inspire more young gamers to become pilots.

TWO MORE BRILLIANT PROJECTS

Created by Popular Science readers

3-D Projector
Copper River, Alaska, science teacher Gene Crow built a 3-D camera and projector system that superimposes two video feeds of the same scene from two cameras at slightly different perspectives, creating the illusion of three dimensions on a two-dimensional screen. Circular polarized filters on the projectors and viewer’s glasses ensure that each eye sees video from only one of the projectors, producing the 3-D effect in the brain.

Since motion enhances the effect, Crow has also mounted the cameras on a remote-controlled vehicle.

Cost $935
Time 8 hours

Cocktail Mixer
Andrew Jaeger, an electrician in Wisconsin, turned a refrigerator into an automated mixed-drink dispenser. After the user chooses a drink on a touchscreen, a logic controller calls up a stored recipe and gives directions to the mixing system inside the fridge. Jaeger stripped the solenoid valves from an old soda-fountain machine, allowing him to route a pressure line of carbon dioxide into each bottle, and a second line that, when opened, causes the liquor or soda to flow out into a glass.

Cost $2,500
Time 3,000 hours
