Company Extends Alkaline Battery Life With Voltage Booster 243 243

New submitter ttsai writes: Batteroo is a Silicon Valley company preparing to release its Batteriser product in September. The Batteriser is a small sleeve that fits around alkaline batteries to boost the voltage to 1.5V. This means that batteries that would otherwise be thrown into the trash when the voltage dips to 1.3V or 1.4V could be used until the unboosted voltage reaches 0.6V, extending the useful life of a battery 8x, according to the company. This product has the potential to reduce the number of batteries in landfills as well as increasing the time between replacing batteries. The expected price of the sleeve is $10 for a pack of 4 sleeves.

Tor Project Aims To Eclipse US Government Funding 53 53

An anonymous reader writes Developed by the U.S. Navy and the recipient of millions of dollars of government grants, the Tor Project is now aiming to ween itself off dependence of U.S. government funds "including setting a goal of 50 percent non-U.S. government funding by 2016." The initiative comes after months of discussion over what some vocal critics deemed a contradiction in funding and purpose.

And it's pretty cool:
The integrated space plan is an update of the document originally drawn up in the 1980s, and has been variously rediscovered since.

It's a long-view look at where we need to go and what we need to get there. In the 1980s, commercial spaceflight was envisioned somewhat differently than it's happened, and robotics have gotten way more capable, so the refresh is definitely needed.

Samsung Announces Galaxy Alpha Featuring Metal Frame and Rounded Corners 220 220

mrspoonsi (2955715) writes with word that Samsung is hopping on the metal case and rounded corners design bandwagon. From the article: Samsung says a metal frame and curved corners give the Galaxy Alpha a "sophisticated" look. The South Korean company describes the Galaxy Alpha as representing a "new design approach". The firm has previously been criticised for the plastic feel of its handsets at a time when other firms have opted to use materials marketed as having a "premium" feel. Samsung Electronics saw a 20% year-on-year drop in its last quarter's profit. The phone features 2G of RAM, a 4.7" AMOLED display, and either an 8-core Exynos 5 or 4-core Snapdragon 801.

Comment Helped diagnose an allergic reaction, too! (Score 1) 47 47

After popping a bunch of benadryl and being satisfied that my condition wasn't worsening, I elected to make a regular appointment with my GP instead of going to Emergency.

I decided to take a few photos of the skin rash before it went away, which allowed the doctor (three days later, when I was totally fine again) to quickly identify that it was indeed an allergic reaction, and based on where it appeared, the subsequent interview helped diagnose the cause. Worked great!

Whenever I try to convert part-15 geeks into part-97 geeks, they're interested in high power, they're interested in DIY equipment, they're interested in satellites, they're interested in propagation, and as soon as I mention that you can't swear or encrypt, they walk away.

"If I can't send useful traffic over it, why would I bother?"

Ham radio is losing a generation of geeks who've grown up on a more-free network and aren't interested in a restricted one. Should we just let them go?

Comment Ricochet did this post-9/11, routing worked fine. (Score 3, Interesting) 45 45

While much of Manhattan's traditional communications infrastructure was literally a smoking crater after 9/11, the Ricochet mesh network was alive and well, built to barely notice the loss of individual nodes.

The company had recently gone bankrupt, but all the hardware was still in place, so some ex-employees drove from Denver to NYC with a bunch of modems and laptops, to bring mobile connectivity to the recovery effort.

Mesh works in this case because MCDN uses geographic routing -- the packet header literally contains a packed lat/long for the destination, and nodes make their routing decisions by angle and distance. There's a layer of name-to-geo resolution which makes that all work, and in the Ricochet days it was centralized, but I believe it could be made to operate with DHT like torrent networks do now.

Comment Your local hackerspace. (Score 1) 49 49

Look at the list of hackerspaces, visit as many as you can find in the local area, and talk to as many people as you can. Most spaces don't have a spokesperson or overarching organization except what's necessary to keep the lights on, so making contact with individuals is important.

If you didn't have to work so hard, you'd have more time to be depressed.
