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.
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.
This is another fine project to come out of the benheck forums. [sam_thornley] built this portable game system last Fall. It uses the guts of a JAKKS Namco TV arcade stick. The composite signal from the board is connected to a 2.5″ Intec screen with a CCFL backlight. Four rechargable AA batteries are in the case for 2.5 hours of play. It doesn’t have sound, but he says the TV games’ sound pales to the original anyway. It’s certainly a nice compact build in a regular project box.
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?
Correction: the 16GB of storage on the Engadget site is a typo. This unit comes with 1GB.
The camera lens on the iPhone is much like any other cameraphone lens in the fact that the lens has a fixed minimum and maximum focus length. If you want to get a little closer to your subject, you just might want to give [eastrain’s] macro camera mod a try.
According to [eastrain] both first and second generation iPhone cameras have a screw type focus ring that has been glued to infinity from the factory. This was probably set so that 99% of your photos were roughly in focus.
Gaining access to the camera lens requires the disassembly of your phone and will undoubtedly void any type of warranty you may have had. Once the lens is in view you will need to break the 2 glue points that hold the lens at its current position.
Using needle nose pliers you can then rotate the lens counter clockwise to increase the zoom or clockwise to decrease it. Enabling the built in camera app allows you to see in real time your changes. When you’re satisfied, just put everything back together. Of course the next step should be an externally mounted ring to allow manual zooming on the fly.
It’s been a long time coming but that highly sought after open source mixer, the aurora224 is now available for purchase on the company’s website. The aurora mixer is a fully programmable USB mixer complete with 24 back lit knobs, 2 faders, and a single crossfader.
While the instructions on how to assemble your own mixer from scratch have been available for sometime now, many wanted a kit complete with everything needed to avoid having to source the parts themselves.
The aurora mixer is available in 2 versions, a fully assembled turn key deck and a DIY kit that requires the use of a soldering iron and the ability to follow directions.
So, if you’ve wanted to build your own aurora mixer but never knew where to start, this may be your lucky day. Don’t wait too long as you have until September 1st to get your order in.
