SignalGen

SignalGen is a free app that outputs relatively low frequency signals with the use of a PC sound card. It is an entirely suitable replacement for a hardware signal generator (electronic instrument that generates repeating electronic signals) for signals of a frequency higher than about 50 KHz.

SignalGen creates any frequency between a fraction of a Hz and an upper limit determined by your sound card's capabilities, typically about 50 KHz. It works like a hardware audio generator, creating sine, triangle, square and sawtooth waves, that can be monitored in real time.

SignalGen is CareWare.

PSP Solar Charger


Solar recharge your PSP, GBA or Nintendo DS for free, using clean environment-friendly energy.

It takes only about 4 hours of sunlight for the PSP Solar Charger to recharge any PSP, Nintendo DS or GBA SP.
Although, in fact it doesn't really need the sunlight since it can even be used indoors and charge from artificial lights.

No power supply is required, which means that now you can take your PSP anywhere (not inside a dark cave, no).

Dimensions:
84 x 82 x 22 mm

Look Ma! No poles, no struts, no tracks. 


Flies at altitude, well above the masthead.


It attaches to your existing winches in the deck, not the mast.
 
It gets 20-30% stronger wind which results in 45-70% more power.


It can even be used for power boats.

Tiny Robots for stomach surgery

Tiny Robots (8 centimeters long) are being developed at the University of Nebraska to provide remote controlled robot abdomen surgery.


The project's mission is to test new minimally invasive surgery techniques.
Specialized devices for illumination, biopsy, clamping and cauterizing are also planned, some of which could move around the stomach or the abdominal cavity.


Dmitry Oleynikov, director of education and training for the minimally invasive and computer-assisted surgery project asserted that: 



“This is just the start of things to come regarding robotic devices at work inside the body during surgery.”


Select an image using the Property Grid.


NASA has shown its interest in the project and said it will teach astronauts to use the robots so that surgeries can be performed in space. They can also be operated from surgeons on Earth, who can control the robots themselves from other locations.


Visit the University of Nebraska to watch an amazing video of a motorized robot doing its job inside a patient's abdomen.
