General requirements for handling LiPo, LiIon and LiFe batteries

When going portable with your electronics projects or diving in to RC hobby you eventually have to deal with batteries. No secret that best what is available today is lithium batteries. They come in many flavors. Why use lithium battery instead of alkaline or NiMh rechargeable? The short answer is – energy density. Lithium Ion batteries can store large amount of energy comparing to its weight and can give out large currents. This technology made it possible to enjoy long and powerful RC model (like quadcopter) flights. To achieve same results with NiMh it looks almost impossible due to weight and low current output. Lithium battery technology is constantly improving as different chemistry is used. You can find lots of info about different chemistry of Lithium Ion batteries so we won’t be getting into this.

Considering Solid-State Relays (SSR) for your projects

Using relays are common way of switching high power loads with electronics. If you take any microcontroller or any other digital IC, you will see that their output current on single pin is very limited – varies around 20mA. Same situation is with voltage. Digital pin output voltage is limited to IS supply voltage like 3.3v or 5V. Usually we need to switch loads that draw significantly higher currents and are powered from higher voltage supply. And there you have several options for switching loads. One and most oldest method is using mechanical relays. They are still very popular way of switching power electronics. One biggest disadvantage of using mechanical relay is that it has moving parts with all rising problems. These are: slow switching time; relatively high control current; noisy; may produce sparks on switching; sensitive to environment factors like vibration, humidity; To overcome those problems there is more…

About PCBs and designing them with pcb design software with altium

A printed circuit board or a PCB is able to provide mechanical support to electronically connected electronic parts of a device using traces which are etched using copper sheets, conductive pathways, etc. laminated on a substrate of a non conductive nature. Usually, there are preset IPC organization standards that help to design the PCB layout, maintain a certain level of quality, and follow a proper assembly pattern accepted by the industry. PCBs usually follow the IPC 2221A standard in terms of design and quality control, and it is the same for any material the PCB is made with. An insulator is a prime component of any PCB, which is home to a variety of layers of materials attached to the insulator itself. All these layers act as a form of grounding to the entire PCB. Now coming to the copper traces – they are created either by mechanical laying of…

Airbus and the Realization of Bionic Design

Five years ago, no one could have predicted the impact that slime mold would have on the air travel industry. This was when the idea for a bionic-design partition for the Airbus first came to the forefront. Engineering designers at Airbus took advantage of 3D printing and generative design software to create the bionic partition for its Concept Cabin. The partition is the only thing that separates passengers from the flight crew. Airbus’ new lightweight design allows greater access for emergency personnel to bring in stretchers. The ability to neatly tuck the partition out of the way means that medics can get sick or injured people off the plane in a hurry. At a weight of 66 pounds, the partition serves as a fold-down chair for the flight crew during take-offs and landings. As impressive as all of this is, what has truly caught the attention of the flying public…

The U.S. and the Changing World of Medicine

There is no doubt that as everything else is evolving with new technology, medicine is too. The issue is that in the US, our medical system is broken and the insurance companies are too rigid. Doctors and other medical personnel have managed to work even with these difficulties and still provide patient care that is excellent along with new techniques that are successful. With the advance of biomedical research, doctors will be able to better tackle health issues in ways that are cost effective. Automation is only one area where there is new technology coming to the fore. Because of this advancement, linear actuators are being used more often as opposed to hydraulic and pneumatic systems. They range in size from very small to very large ones. Aside from the changes that technology has seen, there are quite a few other reasons that have made these actuators necessary, such as…

3 new ways technology is helping to advance medicine

Imaging Cameras improving cancer surgery Every year, 14 million people are diagnosed with cancer; of those, around eight million will die. Cancer is one of the leading causes of death worldwide; across the globe, doctors and scientists are fighting to reduce the number of cancer deaths by detecting cancer early and promoting new ways of battling it. In the past, imaging technologies such as radiography, magnetic resonance imaging and computed tomography have proved vital in the fight against cancer, helping doctors to diagnose the disease quickly to increase the chance of recovery. Now, near-infrared fluorescence (NRF) has emerged as a new, powerful imaging tool in the battle against cancer. NRF imaging is used during surgery to enable surgeons to easily distinguish between healthy tissue and cancerous tissue. Surgery is a highly effective method of treating cancer patients, but its success rate depends largely on how much of the cancer is…

Future of Artificial Intelligence; Its Implementations and Limits

Artificial Intelligence (AI) is the field of computer science which uses mechanical and computational processes to echo almost all aspects of human intelligence. AI can perform multiple functions: sensory interaction with the environment and the ability to make decisions about events that aren’t happened yet without any human assistance whatsoever. Targeted advertising and virtual agents that recognize the patterns of your behavior are much standard in today’s online undertakings. Artificial Intelligence is used by business enterprises in data analysis algorithms which have the highest advantage of analyzing the Big Data, and it also involves customer engaging techniques. Apart from IBM which developed some of the earliest functions of AI, Google and Facebook are also using AI for the analytic purpose of the massive amount of data they receive.
