Sodium Ions Rechargeable Battery Prototype

Posted by GarageLab on December 7, 2015 at 9:20am 0 Comments

A joint of French science institutions just publish an article that claim they produced a rechargeable battery prototype using sodium ions (Na+). This battery has 90 Wh/Kg storage specific energy capacity, what is close to the early lithium batteries.

The sodium ions great advantage for making batteries, instead of lithium, is that sodium is cheap and common. The disadvantage is that it is less efficient as a charge carrier, so it´s necessary to develop materials that can work on higher voltages.

Eye Controlled wheelchair

Posted by GarageLab on December 4, 2015 at 6:58am 0 Comments

Patrick Joyce has a disease called Amyotrophic Lateral Sclerosis (ALS), the same disease from Stephen Hawking. Tired of depending from other people to help with his locomotion, he decided to innovate.

Using an eye-tracking device, vary common on England, he created a device that move an electric wheelchair using the eyes movements, using almost just an Arduino, some relays and servo motors. The system, called Eyedrivomatic, is open hardware and open software so it can help many people.

New Bio-Prothesis Technology

Posted by GarageLab on December 3, 2015 at 4:10am 0 Comments

The OpenBionics just showed a new fabrication method from a hand prosthesis that can help many people. The actual prosthesis have problems like movement’s limitations, price and weight.

 However, the OpenBionics new method, presented at 2015 Hackaday Prize, can solve all these problems. The model have just two motors and, with a very smart design, their hand can make 144 different positions. They also have made a 3D CAD model that can be resized and fabricated with 3D printer or laser cut.

Developing Micro-Lidars

Posted by GarageLab on December 2, 2015 at 8:53am 0 Comments

Light Detection and Ranging (LIDAR) works just like the radar. The lidar take distances measures by illuminating objects with a laser and analyzing the reflected light.

Researchers at Florida University are creating a developing method for micro-lidars que emits invisible light, save for humans eyes, and weight just 56 miligrams. The forecast is that in three years they will finish the technology foundation.

Plants growing using plasma

Posted by GarageLab on November 30, 2015 at 8:53am 0 Comments

Japanese’s Scientists from Kyushu University are working on a project that can helps the world to solve one of the most troublesome problems, the food dearth. The researches show that blasts of plasmas can decrease the crop time besides increase the yields.

The device generate 9.2-kilovolt and 0.2 amp of cold plasma containing a potent mix reactive oxygen and nitrogen molecules, photons, ions, and electrons.

Cooling things with an Infrared Laser

Posted by GarageLab on November 27, 2015 at 6:40am 0 Comments

Lasers (Light Amplification by Stimulated Emission of Radiation) have a large industrial and residential use. A common application is to cut and heat parts using high potency lasers.

However, researchers from Washington University thought about a new utility for this resourceful device, the idea is to refrigerate liquids using an infrared laser. In principle, the idea is to use this breakthrough for biologics uses, so the scientists can freeze a tissue so they can study better its processes.

Nanowire Production New Method could Revolutionize Photonics Applications

Posted by GarageLab on November 26, 2015 at 4:55am 0 Comments

University Wollongong, Australia, researchers just published, in Nanoscale Journal, a new method nanowires production that could revolutionize the telecommunications applications.

The breakthrough is to add bismuth to the elements arsenic and gallium. The idea is that the bismuth resists the arsenic-gallium crystal junction, making a surface coat, which is an array of small droplets.

0-Gravity Jetpack Stabilization using Gyroscope

Posted by GarageLab on November 24, 2015 at 3:38am 0 Comments

The Draper Laboratories, based in Cambridge Massachusetts, are developing a jetpack stabilization system on 0-gravity. The system is called Control Moment Gyroscope (CMG).

The system uses a spinning mass to create torque, allowing rotating an object or creating a resistance to a rotation. It utilizes four gyroscopes and is being tested on 0-gravity airplanes simulator.

3D Printer used unconventionally

Posted by GarageLab on November 23, 2015 at 10:51am 0 Comments

The 3D printers are becoming more and more popular thanks to two important factors, the low price and the use flexibility. Using this printers, and a little of creativity, you can have specified parts to almost any project.

A good example, Yale University made, is a 3D part where they let some shell pieces. Filling these pieces with flexible polyurethane and cutting off the shell structure, they obtained a flexible robotic hand piece.
