Esta Newsletter tem os seguintes tópicos:

Faz hoje anos que nascia, em 1842, o inventor e poeta francês Charles Cros. Ele projectou um telégrafo automático e exibiu-o na Feira Mundial de 1867. Ele enviou à Société française de photographie, em 1869, um sistema de reprodução de imagens coloridas. Além disso, ele entregou planos viáveis em 18 de abril de 1877 para a Académie des Sciences, para um aparelho chamado paleofone, que era o princípio do gramofone. Assim, ele teve a ideia antes de Edison. No entanto, ele morreu na pobreza e nunca foi reconhecido pelas suas descobertas em vida, devido a concorrentes mais influentes e com melhor financiamento.

Faz também hoje anos que nascia, em 1881, o pioneiro da aviação americana William E. Boeing. Ele começou a interessar-se pela aviação quando treinou na escola de voo de Glenn L. Martin em 1915 e comprou sua própria aeronave. Em 1916, Boeing co-fundou a Pacific Aero Products Company (logo renomeada como Boeing Airplane Company). Em 1920, ele recebeu uma grande encomenda de guerra para 200 aviões de combate MB-3. A Boeing Air Transport começou a transportar correio e passageiros em Julho de 1927. Por meio de fusões com outras indústrias de aeronaves, ele construiu a United Aircraft and Air Transport, a empresa de aviação mais lucrativa do seu tempo. Em 1934, a acção da concorrência do governo dividiu a companhia. A United Airlines tornou-se uma empresa independente. Mantém-se até aos dias de hoje como uma das duas grandes companhia de fabrico de aviões comerciais.

Por fim, faz hoje anos que nascia, em 1939, o Astrofísico norte-americano George Robert Carruthers. Ele foi o principal inventor de uma nova câmara espacial para medir a luz ultravioleta que pode ser usada para identificar átomos e moléculas interestelares. Após vários anos em desenvolvimento, foi levada à lua na missão Apollo 16 (1972). Posicionada na superfície da lua, a câmara também pode capturar imagens dos gases da atmosfera terrestre. A concentração de poluentes, como o monóxido de carbono, no ar ao redor de grandes cidades pode ser determinada para muitas cidades ao mesmo tempo. Outras câmaras espaciais desenvolvidas por Carruthers e seus colegas pesquisaram a camada de ozono e transmitiram fotos de estrelas e planetas distantes para análise por computador. Ele também foi pioneiro no desenvolvimento de telescópios electrónicos.

Em 1880, a primeira fábrica de lâmpadas incandescentes eléctricas dos EUA foi inaugurada em Menlo Park, N. J. The Edison Lamp Works. No espaço de um ano e meio foram produzidas mais de 130.000 lâmpadas.

Faz hoje anos que o primeiro protótipo do Concorde (001) passou a barreira do som. O seu primeiro voo tinha sido seis meses antes. Foi durante o seu 102º voo de teste que atingiu Mach 2. O seu "irmão" Inglês alcançou o mesmo resultado uma semana depois. O Concorde foi o primeiro avião do mundo totalmente controlado por computador. No início, grupos ambientais criticaram o ruído do Concorde durante a descolagem e o consumo de combustível. O seu impacto nas viagens aéreas internacionais foi limitado pelos altos custos de operação da aeronave. Apenas a British Airways e a Air France operaram a aeronave. O serviço terminou com voos finais de passageiros a 24 de Outubro de 2003. Não existe até à data nenhuma outra forma comercial de viajar tão rápido.

Na Newsletter desta semana apresentamos diversas noticias, artigos científicos assim como projetos de maker.

New PIC24F MCUs Feature Low-power Animated Display Driver for Battery-powered Devices

"Low-power MCU family offers power-saving peripherals, hardware safety and secure code protection System developers of battery-powered and other power-conscious designs with and without LCD displays can now easily add an array of innovative features using a new line of PIC® eXtreme Low Power (XLP) microcontrollers (MCUs) from Microchip Technology Inc. (Nasdaq: MCHP). Packed with 14 types of Core Independent Peripherals (CIPs) that operate outside the Central Processing Unit (CPU) for power savings, the PIC24F GU and GL families of MCUs feature the CIP called LCD with Autonomous Animation. Most display applications involve a few common animations like periodically alternating between displays and blinking of pixels to indicate operation. By using the integrated LCD driver with autonomous animation, developers can offload most of these simple animation routines from the CPU, allowing animation even in doze, idle or sleep modes for optimal power savings. To assist in quickly designing such display interfaces, the new MCUs come with MPLAB® Code Configurator (MCC) support. This graphical programming environment with LCD display designer helps eliminate the meticulous and time-consuming task of mapping the pins and segments." [...]

Accelerating Recycling-Oriented Manufacturing with Plant-Derived Cellulose Fiber

Accelerating Recycling-Oriented Manufacturing with Plant-Derived Cellulose Fiber

"Panasonic has over 300 manufacturing sites around the world. In order to reduce the amount of plastic used at these sites and to contribute to the realization of a circular society, Panasonic has been undertaking research and development of eco-conscious materials that can potentially replace plastics. In 2019, Panasonic introduced a composite processing technology that combines a high concentration of plant-derived cellulose fiber resin. As a molding material that will further promote recycling-oriented manufacturing, it is already being applied to chassis of consumer electronics, reusable cups, etc. Worldwide, more than 300 million tons of plastic is being consumed every year, and this number is still on the rise. On the other hand, only 14% is being recycled (according to documents published by the United Nations Environment Programme)." [...]

Toshiba’s Cascode GaN Discrete Power Device Realize Stable Operation and Simplifies System Design with Direct Gate Drive

Toshiba’s Cascode GaN Discrete Power Device Realize Stable Operation and Simplifies System Design with Direct Gate Drive

"Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has developed a gallium nitride (GaN) cascode with a direct gate drive that realizes stable operation and simplification of system design. The device reduces risk of additional energy loss during switching due to false on, and like silicon its switching speed can be easily adjusted, an important consideration in the design of power electronics systems. Details of the new discrete device were reported at the IEEE-sponsored International Symposium on Power Semiconductor Devices and ICs 2020 (ISPSD 2020), held online. GaN power devices are candidates for achieving high efficiency and downsizing systems. They are currently used in quick chargers for smartphones and computers, and are expected to be adopted in the power supply of industrial equipment and servers. Generally, power devices need to be normally-off, but GaN high-electron-mobility transistors (HEMTs) are normally-on." [...]

A self-erasing chip for security and anti-counterfeit tech

A self-erasing chip for security and anti-counterfeit tech

"Self-erasing chips developed at the University of Michigan could help stop counterfeit electronics or provide alerts if sensitive shipments are tampered with. They rely on a new material that temporarily stores energy, changing the color of the light it emits. It self-erases in a matter of days, or it can be erased on demand with a flash of blue light. “It’s very hard to detect whether a device has been tampered with. It may operate normally, but it may be doing more than it should, sending information to a third party,” said Parag Deotare, assistant professor of electrical engineering and computer science. With a self-erasing bar code printed on the chip inside the device, the owner could get a hint if someone had opened it to secretly install a listening device." [...]

Validating the physics behind the new MIT-designed fusion experiment

Validating the physics behind the new MIT-designed fusion experiment

"Seven studies describe progress thus far and challenges ahead for a revolutionary zero-emissions power source. Two and a half years ago, MIT entered into a research agreement with startup company Commonwealth Fusion Systems to develop a next-generation fusion research experiment, called SPARC, as a precursor to a practical, emissions-free power plant. Now, after many months of intensive research and engineering work, the researchers charged with defining and refining the physics behind the ambitious tokamak design have published a series of papers summarizing the progress they have made and outlining the key research questions SPARC will enable. Overall, says Martin Greenwald, deputy director of MIT’s Plasma Science and Fusion Center and one of the project’s lead scientists, the work is progressing smoothly and on track. This series of papers provides a high level of confidence in the plasma physics and the performance predictions for SPARC, he says. No unexpected impediments or surprises have shown up, and the remaining challenges appear to be manageable." [...]

Development of Highly Compact Radar Sensors for Industry

Development of Highly Compact Radar Sensors for Industry

"Radar systems have long been used on aircraft or ships. Now, they are increasingly applied in cars for the “short range” in particular. Thanks to the great progress achieved in semiconductor technology in the past years, another miniaturization step is now possible. For this, researchers of Karlsruhe Institute of Technology (KIT), in cooperation with the Fraunhofer Institute for Applied Solid State Physics (IAF) in Freiburg and the industry partner VEGA Grieshaber KG, develop highly compact radar sensors of modular design that are excellently suited for various applications in industry. A so far unmatched resolution can be reached by radar sensors, in which antennas can be integrated in chips or in the chip housing due to the small wavelength. However, frequencies above 100 GHz have hardly been used so far, as this requires extremely complex mounting and connection technologies." [...]

Wired Up: Majorana Fermions for Quantum Computing

Wired Up: Majorana Fermions for Quantum Computing

"Majorana fermions exhibit a strange property: these exotic particles cannot be distinguished from their own antiparticles. Nevertheless, technically they could be extremely useful as qubits for quantum computers. This is because every two Majorana fermions form an entangled pair that can be extremely resistant to external influences. However, Majorana fermions are very difficult to detect. This is a major hurdle for their production and characterization. Scientists from Forschungszentrum Jülich and RWTH Aachen University together with partners from the University of Hamburg can now demonstrate a possible way around this difficulty." [...]

Noble Metal Clusters Can Enhance Performance of Catalysts and Save Resources

Noble Metal Clusters Can Enhance Performance of Catalysts and Save Resources

"Billions of noble metal catalysts are used worldwide for the production of chemicals, energy generation, or cleaning the air. However, the resources required for this purpose are expensive and their availability is limited. To optimize the use of resources, catalysts based on single metal atoms have been developed. A research team of Karlsruhe Institute of Technology (KIT) demonstrated that noble metal atoms may assemble to form clusters under certain conditions. These clusters are more reactive than the single atoms and, hence, exhaust gases can be much better removed. The results are reported in Nature Catalysis (DOI: 10.1038/s41929-020-00508-7)." [...]

Microelectronics shed light on neural behaviour

Microelectronics shed light on neural behaviour

"Researchers at ETH Zurich – in collaboration with colleagues from EPFL in Lausanne and Harvard Medical School – have developed a system that allows them to optically stimulate individual nerve fibres in living mice. Through this process, they have demonstrated that the nervous system has a direct influence on the immune system. Over the last ten years, a new method has literally shed more light on the brain. “Optogenetics” allows scientists to deliberately stimulate genetically modified nerve cells and thoroughly investigate their functioning within the complex network inside the skull. This technique represents a revolution in neuroscience, but to date, it could only be applied to study the central nervous system, but not the peripheral nervous system. Miniaturisation through chip technology Now, a team of electrical engineers led by Qiuting Huang, a professor at the Institute for Integrated Systems at ETH Zurich, together with researchers from EPFL in Lausanne and Harvard Medical School, have developed a system that connects implantable light emitting diodes (LED) with a tiny device on the subject’s head which can be controlled from a tablet via Bluetooth."

Robotic Fabric: A Breakthrough with Many Uses

Robotic Fabric: A Breakthrough with Many Uses

"Researchers at Yale have developed a robotic fabric, a breakthrough that could lead to such innovations as adaptive clothing, self-deploying shelters, or lightweight shape-changing machinery. The lab of Prof. Rebecca Kramer-Bottiglio has created a robotic fabric that includes actuation, sensing, and variable stiffness fibers while retaining all the qualities that make fabric so useful - flexibility, breathability, small storage footprint, and low weight. They demonstrated their robotic fabric going from a flat, ordinary fabric to a standing, load-bearing structure. They also showed a wearable robotic tourniquet and a small airplane with stowable/deployable fabric wings. The results are published this week in Proceedings of the National Academy of Sciences. The researchers focused on processing functional materials into fiber-form so they could be integrated into fabrics while retaining its advantageous properties." [...]

Detection of gravitational wave 'lensing' could be some way off

Detection of gravitational wave 'lensing' could be some way off

"Gravitational wave scientists looking for evidence of ‘lensing’, in which the faintest gravitational wave signals become amplified, are unlikely to make these detections in the near future according to new analysis by scientists at the University of Birmingham. A team in the University’s School of Physics and Astronomy and the Institute for Gravitational Wave Astronomy has analysed currently available gravitational wave data to predict that these elusive signals are likely to remain undetected by the instruments currently operated by the LIGO and Virgo Collaboration. The existence of gravitational lensing was predicted by Einstein and is a well-recognised phenomenon in relation to light waves. Light emitted by distant objects in the Universe is bent by the gravitational pull of other massive objects, such as galaxies when the light source passes behind them. When detected by the earth’s telescopes, this distortion might make the light-emitting object seem larger or closer to earth than it actually is. Scientists predict that the same will be true of signals from gravitational waves – but we won’t find them just yet." [...]

Quantum Matchmaking: New NIST System Detects Ultra-Faint Communications Signals Using the Principles of Quantum Physics

Quantum Matchmaking: New NIST System Detects Ultra-Faint Communications Signals Using the Principles of Quantum Physics

"Researchers at the National Institute of Standards and Technology (NIST) have devised and demonstrated a system that could dramatically increase the performance of communications networks while enabling record-low error rates in detecting even the faintest of signals, potentially decreasing the total amount of energy required for state-of-the-art networks by a factor of 10 to 100. The proof-of-principle system consists of a novel receiver and corresponding signal-processing technique that, unlike the methods used in today’s networks, are entirely based on the properties of quantum physics and thereby capable of handling even extremely weak signals with pulses that carry many bits of data. “We built the communication test bed using off-the-shelf components to demonstrate that quantum-measurement-enabled communication can potentially be scaled up for widespread commercial use,” said Ivan Burenkov, a physicist at the Joint Quantum Institute, a research partnership between NIST and the University of Maryland. Burenkov and his colleagues report the results in Physical Review X Quantum. “Our effort shows that quantum measurements offer valuable, heretofore unforeseen advantages for telecommunications leading to revolutionary improvements in channel bandwidth and energy efficiency.” Modern communications systems work by converting information into a laser-generated stream of digital light pulses in which information is encoded — in the form of changes to the properties of the light waves — for transfer and then decoded when it reaches the receiver. The train of pulses grows fainter as it travels along transmission channels, and conventional electronic technology for receiving and decoding data has reached the limit of its ability to precisely detect the information in such attenuated signals." [...]

The Return of the Spin Echo

The Return of the Spin Echo

"A research team from Garching and Vienna discovered a remarkable echo effect – it offers exciting new possibilities for working with quantum information. Small particles can have an angular momentum that points in a certain direction – the spin. This spin can be manipulated by a magnetic field. This principle, for example, is the basic idea behind magnetic resonance imaging as used in hospitals. An international research team has now discovered a surprising effect in a system that is particularly well suited for processing quantum information: the spins of phosphorus atoms in a piece of silicon, coupled to a microwave resonator. If these spins are cleverly excited with microwave pulses, a so-called spin echo signal can be detected after a certain time – the injected pulse signal is re-emitted as a quantum echo." [...]

Scientists achieve higher precision weak force measurement between protons, neutrons

Scientists achieve higher precision weak force measurement between protons, neutrons

"Through a one-of-a-kind experiment at the Department of Energy’s Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result quantifies the weak force theory as predicted by the Standard Model of Particle Physics. The team’s weak force observation, detailed in Physical Review Letters, was measured through a precision experiment called n3He, or n-helium-3, that ran at ORNL’s Spallation Neutron Source, or SNS. Their finding yielded the smallest uncertainty of any comparable weak force measurement in the nucleus of an atom to date, which establishes an important benchmark. The Standard Model describes the basic building blocks of matter in the universe and fundamental forces acting between them. Calculating and measuring the weak force between protons and neutrons is an extremely difficult task." [...]

The next big thing: the use of graph neural networks to discover particles

The next big thing: the use of graph neural networks to discover particles

"Machine learning algorithms can beat the world’s hardest video games in minutes and solve complex equations faster than the collective efforts of generations of physicists. But the conventional algorithms still struggle to pick out stop signs on a busy street. Object identification continues to hamper the field of machine learning — especially when the pictures are multidimensional and complicated, like the ones particle detectors take of collisions in high-energy physics experiments. However, a new class of neural networks is helping these models boost their pattern recognition abilities, and the technology may soon be implemented in particle physics experiments to optimize data analysis. This summer, Fermilab physicists made an advance in their effort to embed graph neural networks into the experimental systems. Scientist Lindsey Gray updated software that allows these cutting-edge algorithms to be deployed on data from the Large Hadron Collider at CERN." [...]

Scientists Offer Companies a Novel Chemistry for Greener Polyurethane

Scientists Offer Companies a Novel Chemistry for Greener Polyurethane

"Groundbreaking Formulation Enables Renewable, Nontoxic Polyurethane—a Potential Drop-In Solution for Companies’ Products Without it, the world might be a little less soft and a little less warm. Our recreational clothing might shed less water. The insoles in our sneakers might not provide the same therapeutic arch support. The wood grain in finished furniture might not “pop.” Indeed, polyurethane—a common plastic in applications ranging from sprayable foams to adhesives to synthetic clothing fibers—has become a staple of the 21st century, adding convenience, comfort, and even beauty to numerous aspects of everyday life. The sheer versatility of the material, which is currently made largely from petroleum byproducts, has made polyurethane the go-to plastic for a range of products. Today, more than 16 million tons of polyurethane are produced globally every year." [...]

LSU Physicists Develop and Demonstrate a Method to Eliminate Quantum Radiation Pressure Noise in Gravitational Wave Detectors

LSU Physicists Develop and Demonstrate a Method to Eliminate Quantum Radiation Pressure Noise in Gravitational Wave Detectors

"By quieting the quantum whisper, we can now listen to the more subtle notes of the cosmic symphony. Gravitational wave detectors have opened a new window to the universe by measuring the ripples in spacetime produced by colliding black holes and neutron stars, but they are ultimately limited by quantum fluctuations induced by light reflecting off of mirrors. LSU Ph.D. physics alumnus Jonathan Cripe, postdoctoral fellow, NIST, and his team of LSU researchers have conducted a new experiment with scientists from Caltech and Thorlabs to explore a way to cancel this quantum backaction and improve detector sensitivity. In a new paper in Physical Review X, the investigators present a method for removing quantum backaction in a simplified system using a mirror the size of a human hair and show the motion of the mirror is reduced in agreement with theoretical predictions. The research was supported by the National Science Foundation. Despite using 40-kilogram mirrors for detecting passing gravitational waves, quantum fluctuations of light disturb the position of the mirrors when the light is reflected." [...]

Thin and ultra-fast photodetector sees the full spectrum

Thin and ultra-fast photodetector sees the full spectrum

"Researchers have developed the world’s first photodetector that can see all shades of light, in a prototype device that radically shrinks one of the most fundamental elements of modern technology. Photodetectors work by converting information carried by light into an electrical signal and are used in a wide range of technologies, from gaming consoles to fibre optic communication, medical imaging and motion detectors. Currently photodetectors are unable to sense more than one colour in the one device. This means they have remained bigger and slower than other technologies, like the silicon chip, that they integrate with. The new hyper-efficient broadband photodetector developed by researchers at RMIT University is at least 1,000 times thinner than the smallest commercially available photodetector device. In a significant leap for the technology, the prototype device can also see all shades of light between ultraviolet and near infrared, opening new opportunities to integrate electrical and optical components on the same chip." [...]

Terraced graphene for ultrasensitive magnetic field sensor

Terraced graphene for ultrasensitive magnetic field sensor

"NUS physicists have developed a sensitive two-dimensional (2-D) magnetic field sensor, which can potentially improve the detection of nanoscale magnetic domains for data storage applications. Magnetoresistance (MR), the change in the electrical resistance of a material due to the influence of an external magnetic field, has been widely used in magnetic sensors, magnetic memories, and hard disk drives. However, in traditional three-dimensional (3D) material-based magnetic sensors that use giant MR (GMR) or tunneling MR (TMR) spin-valves, the detectable signal of the magnetic field decays exponentially with the thickness of its sensing layer. This limits the spatial resolution and sensitivity of the sensors. Therefore, a 2D-based sensor can potentially improve the detection of minuscule magnetic fields, as the decay is limited to only one atomic layer thickness. Graphene is an atom-thick thin material with high mobility and high current carrying capability." [...]

INRS Researchers Develop a New Membraneless Fuel Cell

INRS Researchers Develop a New Membraneless Fuel Cell

"The research team of INRS (Institut national de la recherche scientifique) Professor Mohamed Mohamedi has designed a green membraneless fuel cell that uses oxygen from the air. The results of this innovative microfluidic application—a first in Canada—were published in Renewable and Sustainable Energy Reviews. Conventional fuel cells are ubiquitous. They power electric cars on today’s roads and were part of the computers used in the 1969 Apollo moon landing. These fuel cells lose voltage as they are used and eventually stop working. This happens because alcohol molecules (methanol or ethanol) in the fuel cell’s anode compartment crossover the membrane separating them from the cathode compartment." [...]

New detector breakthrough pushes boundaries of quantum computing

New detector breakthrough pushes boundaries of quantum computing

"A new paper published in Nature shows potential for graphene bolometers to become a game-changer for quantum technology Physicists at Aalto University and VTT Technical Research Centre of Finland have developed a new detector for measuring energy quanta at unprecedented resolution. This discovery could help bring quantum computing out of the laboratory and into real-world applications. The results have been published today in Nature. The type of detector the team works on is called a bolometer, which measures the energy of incoming radiation by measuring how much it heats up the detector. Professor Mikko Möttönen’s Quantum Computing and Devices group at Aalto has been developing their expertise in bolometers for quantum computing over the past decade, and have now developed a device that can match current state-of-the-art detectors used in quantum computers. ‘It is amazing how we have been able to improve the specs of our bolometer year after year, and now we embark on an exciting journey into the world of quantum devices,’ says Möttönen."

Chemical innovation stabilizes best-performing perovskite formulation

Chemical innovation stabilizes best-performing perovskite formulation

"Publishing in Science, researchers at EPFL have successfully overcome a limiting problem with stabilizing the best-performing formulation of metal-halide perovskite films, a key player in a range of applications, including solar cells. Perovskites are a class of materials made up of organic materials bound to a metal. Their fascinating structure and properties have propelled perovskites into the forefront of materials’ research, where they are studied for use in a wide range of applications. Metal-halide perovskites are especially popular, and are being considered for use in solar cells, LED lights, lasers, and photodetectors. For example, the power-conversion efficiency of perovskite solar cells (PSCs) have increased from 3.8% to 25.5% in only ten years, surpassing other thin-film solar cells – including the market-leading, polycrystalline silicon. Perovskites are usually made by mixing and layering various materials together on a transparent conducting substrate., which produces thin, lightweight films." [...]

Sensor with 100,000 times higher sensitivity could bolster thermal imaging

Sensor with 100,000 times higher sensitivity could bolster thermal imaging

"Army-funded research developed a new microwave radiation sensor with 100,000 times higher sensitivity than currently available commercial sensors. Researchers said better detection of microwave radiation will enable improved thermal imaging, electronic warfare, radio communications and radar. Researchers published their study in the peer-reviewed journal Nature. The team includes scientists from Harvard University, The Institute of Photonic Sciences, Massachusetts Institute of Technology, Pohang University of Science and Technology, and Raytheon BBN Technologies. The Army, in part, funded the work to fabricate this bolometer by exploiting the giant thermal response of graphene to microwave radiation. “The microwave bolometer developed under this project is so sensitive that it is capable of detecting a single microwave photon, which is the smallest amount of energy in nature,” said Dr. Joe Qiu, program manager for solid-state electronics and electromagnetics, Army Research Office, an element of the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory."

Superconductivity with a twist explained

Superconductivity with a twist explained

"Leiden physicists and international colleagues from Geneva and Barcelona have confirmed the mechanism that makes magic-angle graphene superconducting. This is a key step in elucidating high-temperature superconductivity, a decades-old mystery central to physics, which may lead to technological breakthroughs. Magic-angle materials form a surprising recent physics discovery. 'You take a sheet of graphene', says Sense Jan van der Molen, referring to the two-dimensional material made of carbon atoms in a hexagonal pattern, 'then you put another layer on top of it and twist the latter by 1 degree. This way, you suddenly get a superconductor.' At a temperature of 1.7 Kelvin, twisted bilayer graphene (tbg) conducts electricity without resistance." [...]

3D camera earns its stripes at Rice

3D camera earns its stripes at Rice

"Engineers develop Hyperspectral Stripe Projector to quickly merge depth, spectral data Stripes are in fashion this season at a Rice University lab, where engineers use them to make images that plain cameras could never capture. Their compact Hyperspectral Stripe Projector (HSP) is a step toward a new method to collect the spatial and spectral information required for self-driving cars, machine vision, crop monitoring, surface wear and corrosion detection and other applications. “I can envision this technology in the hands of a farmer, or on a drone, to look at a field and see not only the nutrients and water content of plants but also, because of the 3D aspect, the height of the crops,” said Kevin Kelly, an associate professor of electrical and computer engineering at Rice’s Brown School of Engineering. “Or perhaps it can look at a painting and see the surface colors and texture in detail, but with near-infrared also see underneath to the canvas.” Kelly’s lab could enable 3D spectroscopy on the fly with a system that combines the HSP, a monochrome sensor array and sophisticated programming to give users a more complete picture of an object’s shape and composition. “We’re getting four-dimensional information from an image, three spatial and one spectral, in real time,” Kelly said. “Other people use multiple modulators and thus require bright light sources to accomplish this, but we found we could do it with a light source of normal brightness and some clever optics.” The work by Kelly, lead author and Rice alumna Yibo Xu and graduate student Anthony Giljum is detailed in an open-access paper in Optics Express."

1A Over Current Protection Load Switch

1A Over Current Protection Load Switch

"The Over-current limit load switch project presented here provides full protection to devices and loads from access load conditions. The default current limit is set to 1 Amp, however, this load limit is adjustable from 0.4A to 2A with the help of R4 ISET resistor. When an overload condition occurs circuit responds to that overload condition that lasts longer than a fixed blanking period by turning off the load, followed by a retry after the auto-restart time, auto-retry time is 127.5ms. Flag output is pulled up with R1 and the board provides active low output in a fault condition, normally Flag output is high. Power good output is also pulled up and it’s an open-drain output to indicate that the output voltage has reached 90% of the input voltage. The input range of this circuit is 5V to 24V DC." [...]

Smart gardening without coding - all free and open source

Smart gardening without coding - all free and open source

"All open source, no coding, remote accessible DIY automated smart irrigation. Not this time! I've been growing some tomatoes, chili peppers and other vegetables on my balcony for a couple of years now and while in general I did reasonably well (I'm really not a gardener but I enjoy figuring out how to make things grow) the biggest issue was really when in August I went abroad for summer holidays and instructed my neighbors to take care of my plants. While they probably did their best, it wasn't really enough. One year I returned and the tomatoes were close to drying out (reducing the harvest quite a bit), the other year they were flooded. So I decided that this year I'd take care of it myself." [...]

Pixie - Let Your Plant Smart

Pixie - Let Your Plant Smart

"Pixie was a project developed with the intention of making the plants we have at home more interactive, since for most people one of the challenges of having a plant at home is to know how to take care of it, how often we water, when and how much sun is enough, etc. While sensors work to obtain plant data, a LED display, purposely pixelated (hence the name Pixie), displays basic expressions that indicate the state of the plant, such as joy while it is being watered or sadness if the temperature is too high, indicating that it should be taken to a cooler place. To make the experience even more interesting, other sensors such as presence, touch and luminosity have been added, translating into other expressions that make it seem that you now have a virtual pet to take care of. The project has several parameters where it is possible to customize the limits and needs of each case, considering the diversity of plants as well as sensors of different brands. As we know, there are plants that need more sun or water while others can live with fewer resources, such as cacti for example, in cases like this, having parameters is a must have. Throughout this article, I will present the operation and an overview about how to build a Pixie using a little knowledge of electronics, components easily found in the market and a 3d printed case."

Mirroring Robot Movements with Packet Radios

Mirroring Robot Movements with Packet Radios

"Use a couple of packet radio boards to mirror one robot's movements in the other one from up to 500m away. Swarm Robots The idea of having a large number of robots doing tasks in unison is nothing new, as there have been quadcopters drawing designs with LEDs at events like the Sochi Olympics, and convoys of trucks all moving together. What I wanted to do with this project was explore how this could be accomplished using cheap hardware and at greater distances apart, since Bluetooth can only reach about 45m away before the signal becomes too weak. Packet Radio Principles of Operation The Adafruit Feather M0 used for this project contains an onboard RFM69 radio module, and it can operate in one of two modes. The first one is a continuous stream of data from one point to the other, much like how a pair of walkie-talkie radios would function. This can lead to a lot of data being missed or corrupted, and it's more difficult to build an application layer on top of it." [...]

Fermentation Quilt

Fermentation Quilt

"This project was produced during an artist residency with Loomia in 2020. Fermentation Quilt is a cloth equipped with soft heaters along with thoughtful textile structures that offers a user the chance to think about their personal heritage and cultural context while participating in a daily ritual of making bread, yogurt, or other fermented foods. Inspired by the traditional Bulgarian yogurt Petars grandmother K (and many great grandmothers before her) made using hand-knit scarves, Fermentation Quilt is both a futuristic object and a mirror for personal narrative and cultural history. In the wake of pivotal, current movements like Black Lives Matter and Environmental Sustainability when we are all asking, how can I be a more thoughtful neighbor and consumer?, this project weaves together the practical application of Loomia e-textiles with a framework for actively incorporating reflection into our everyday lives. We are inspired by artists and thinkers like Ashley Jane Lewis, Lauren Fournier, Shaina Agbayani, Robin Zabiegalski, and Ursula K. LeGuin along with social movements like the American Suffragettes and others. Additional Note: If youre curious to learn more about sewing, soldering, electrical circuitry, coding, quilting, e-textiles, or fermentation, we recommend you consult the other incredible resources available in those disciplines online or elsewhere."

Water Optic Communication

Water Optic Communication

"Introduction I was recently watching the TV show Modern Marvels where they were doing this episode on "glass" and spent some time showing how fiber optic cables work. They showed that the concept of total internal reflection also applies to water (I believe they had the bucket of water with a hole so water was flowing out of it in a curved shape with a laser beam bouncing through the stream.. if not I saw it somewhere else). I was curious if I could fill a rubber hose with water and transmit data through it using a bright LED using this property. I ended up getting it working and it's like... speed of light fast! Well, speed of light blinking UART at 9600 baud. I used a Microchip ATtiny85 that basically relays the signals from a USB/UART cable." [...]

Solar Scare Mosquito 2.0

Solar Scare Mosquito 2.0

"An open-source IoT platform to monitor and prevent epidemics such as Malaria, Dengue and the Zika Virus. This solar-powered device eliminates mosquito larvae in stagnant water bodies such as water tanks, swamps and micro-dams. The system allows mosquitoes to lay eggs at dawn and dusk and the intermittent ripples during the day prevent larvae from breathing at the surface. In addition, a built-in microphone captures the wing-beat frequencies of mosquitoes that are naturally attracted to standing water, helping us to identify the species and sex of the mosquito. With a network of these connected devices installed among at-risk populations, we will obtain a real-time estimate of the presence of dangerous mosquitoes. Using this data, we will create the early warning system for all mosquito-borne epidemics." [...]
