Toaster Oven Computer Modification

A while back I built a Mini-Itx computer in a toaster oven. I posted it on my website here:

My Mini-Itx Toaster Computer

Unfortunately the Toaster Computer is no more. The motherboard suffered from the rash of fake capacitors that China flooded the market with and…

Sodium Ions Rechargeable Battery Prototype

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…

Eye Controlled wheelchair

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…

New Bio-Prothesis Technology

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…

Developing Micro-Lidars

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.

Nanowire Production New Method could Revolutionize Photonics Applications

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.

Smell Colors Mask

 

Synesthesia is a mix-up of the senses, when some sensation induce another.  Like when someone can sense the taste after seeing a picture of his favorite food, or when someone can see something just by hearing aleatory noise, or music.

Thinking about it Zachary decided to emulate the synesthesia from the color to smell. He used a color sensor that measure variations from red, green and blue and, from this measures, the system liberates a certain proportion from three…

Optimizing Crops Fields with IoT

Individual soil moisture probe

On Future Hacks Internet of Things Edition, held in Madrid from 9 to 11 October, developers had to form teams and the create solution for daily needs using internet of things (IoT).

The winner project was the optimizing of crops fields. This project make readings of the soil, like humid, and control an irrigation system to optimize the plants grow. They used Arduinos with ESP8266 modules and some sensors of humid, temperature and pressure.

New Software to Mind Reading

Scientists and engineers, from the BrainGate project, just published a paper, in the journal Science Translational Medicine, claiming they created a new decoder that senses mental electric signals with more efficiency. The main upgrade is on the software that compensate for the irregular nature of the neural signals.

Preliminary tests done using a typing interface, where a person with Amyotrophic Lateral Sclerosis could type with a good control of the interface. …

Android Robot

Android Robot

Each year more and more investments is done to develop android robots that can make simple tasks of our day. However that is not easy to be done as it seems. Drive a car, open a door or use a drill are actions that needs a lot of engineering.

The International Conference on Intelligent Robots and Systems in Humburg, Germany, was one of the biggest expo of this area and made a competition where the robots had to do eight simple tasks from a day of…

Sensors for Robotic Surgery

New pop-up sensor may help robotic surgery

Cirurgias feitas por robôs estão se tornando cada vez mais comuns, já que elas têm mostrado que os pacientes têm um tempo de hospitalização reduzido além de diminuir os riscos de erro e infecção, tornando a cirurgia mais segura. Uma grande desvantagem deste método de cirurgia, em comparação com cirurgias feita por pessoas, é que não existem sensores sensíveis e pequenos o suficiente para integrar o sistema que fará a operação.

Pensando nisso, os institutos John A.…

Information Trade Between Cars by Wi-Fi

The talk between cars is in test on the inaugurated Digital recently A9 Motorway Testbed in German. According with the minister of transport and infrastructure, Alexander Dobrindt, “This is the first demonstration of car-to-car communication via a high-speed cellular connection with near-5G performance”

This information trade between cars will allow that the cars know the location of others cars so they can control the speed according with the traffic.
