Solar Powered Ice Maker

solar powered ice maker
Producing ice without electricity just got a lot easier thanks to these engineering students from San Jose State University. Their system uses solar heat to facilitate evaporation of a coolant. When the sun goes down and the coolant turns back to liquid, its temperature drops drastically due to extreme pressure differences. The unit can produce 14 pounds of ice per day with zero carbon footprint. It has no moving parts and an entirely sealed system, this should mean that the only maintenance necessary would be keeping the unit clean.

Comcast Announces 250GB Bandwidth Cap


Today, Comcast updated their Acceptable Use Policy to cover exactly what they feel is “excessive use”. When the Comcast cap starts October 1st, they will contact people breaking the 250GB per month transfer limit and ask them to curb their usage. While it’ll be hard for most people to hit this limit, we still wonder if policing 0.1% of the customer base is worth the effort. At least Comcast has bothered to state the limit instead of just secretly rewriting the meaning of the word “unlimited” like some providers.

GP3X To Be Released In October


You should be able to get your hands on your Wiz as soon as October. The Wiz, also known as the GP3X is the highly anticipated follow up to the GP2X, a handheld game system that runs linux. Sporting a 533 MHz ARM processor, 64 MB of RAM, a 2.8 inch OLED display, 5 hour battery life, and 16 GB of storage, its a heck of a deal. Where else can you get a portable with those specs, bundled with Flash player 7, DivX, Xvid, and MPEG playback for $179?

These units are supposed to be as hackable as the previous version. We’ve seen GPS and USB ports added as well as qtopia and Windows 95 run on them.

Correction: the 16GB of storage on the Engadget site is a typo. This unit comes with 1GB.

Security Flaw Allows Full Access To Locked IPhones

[greenmymac] on the MacRumors forums recently exposed a security flaw that allows anyone full access to a locked iPhone running firmware version 2.0.2. The flaw works by entering the emergency call menu of a locked iPhone, and double tapping the home button. This opens the iPhone’s Favorites menu, allowing anyone in your Favorites to be called. From here, an attacker has access to your SMS messages and potentially your email or Safari browser. While we are sure that Apple has a patch for this flaw on the way in the next firmware update, there is a temporary way to secure your locked iPhone. Simply enter the Settings menu on your iPhone and enter General > Home Button and select “Home” or “iPod”. Now when you double tap your home button, it will navigate to either your home screen or the iPod screen. While this fix might be annoying for some, as of right now it seems like the only way to secure your locked iPhone.

High School Students Hacking Electronic Tests


[Alex Papadimoulis] wrote about ingenuity and hacking in high school. Immediately after the teacher’s installed a new electronic note taking and test giving software, the students began hacking. They managed to find several ways to ace their tests, none of which involved studying hard the night before. Ultimately, the teachers went back to the old system to prevent such shenanigans.

Key Features Cut Out Of Android API


Google has decided that its initial release of the Android SDK will not include formal Bluetooth support or Google Talk. Bluetooth headsets will still work, but developers will not have access to the Bluetooth portion of the API. Google’s security researchers have announced that Google Talk was left out because of multiple security concerns. Bluetooth, on the other hand, was left out because the development team ran out of time.

Out of these two features, we think users are going to be most disappointed by the omission of Google Talk. Chatting has become one of the most useful features of new smart phones. The ability to just chat instead of sending a text message is one of the main attractions to phones like the iPhone, which has support for AIM.
