Turn-key PCB assembly services in prototype quantities or low-volume to mid-volume production runs

PCBWay comes with new excellent service – rapid prototyping

When you think what new can a PCB fab house offer – PCBway pulls something new and exciting out of the sleeve. Recently they have introduced a rapid prototyping manufacturing. This is way beyond PCB fabrication because prototyping covers CNC machining, sheet metal fabrication, 3D printing and even injection moulding. So not you can get PCB and take care of mechanical parts such as enclosures and dynamic components. CNC machining CNC machining allows milling complex parts out of raw material using programmed tools. CNC service includes milling, lathe, laser machine, water jet machine, electric discharge machine – all that may be needed to cut complex 3-dimensional parts. While other CNC technologies are used to cut raw material, the main work is performed by CNCN milling and CNC turning. CNC milling uses a router bit and 3-axis system to move it around the workpiece. More complex parts may be prepared by using up to 6-axis system. CNC turning is used when the part needs to be symmetrical around a single axis. The workpiece is rotated, and two axis-controlled blade removes material from workpiece until the piece is finished. Sometimes multiple milling technologies are incorporated to produce complex parts. CNC machining is…

Intestinal Robots

Intestinal robots are artificial electromechanical systems – robots – that were designed for exploring the inner cavities and organs of the body, particularly the intestines and other parts of the digestive tract.  Built to replace or provide an alternative to colonoscopy, currently the only option for taking a look inside the human body (this is done by inserting a tube through a convenient orifice), intestinal robots have gained much attention from the medical community.  Due to the minute size of the circuitry that has to be used in intestinal robots, they are seen as a field for technological development and as an application of Moore’s Law. First-Generation Robots The first wave of intestinal robots was mostly designed to pass through the body passively.  The primary component of these robots was a miniaturized camera that took still images or video as it passed through the patient’s body.  An early example of this kind of robot was the camera that was integrated into a pill, which could then be swallowed (and consequently passed out) by the patient.

Robotic Assistance for the Disabled

Embedded devices, particularly digital ones specially designed to assist individuals with disabilities, are often seen as the next step in that particular field of technology.  Such embedded devices generally have several advantages over the previous wave of embedded devices that have monitoring functions, control capabilities and the ability to access and use communication protocols like the internet.  The modern embedded applications devices do not stop monitoring, tracking and relaying information; they almost always directly assist the user, such as in the form of a prosthetic limb or a personal transport assistance vehicle.

Embedded Electronics in Space and Medicine

Embedded medical and space systems make use of miniaturized computers that are designed and programmed to do only one or a very limited number of functions. Their minute size and very low energy demands allow them to be used in several environments. Combined with other systems, they can be used to create any number of new devices. Embedded Systems in Medicine Because of their small size and their specificity in function, embedded systems have been widely used in medicine, especially when used as a relatively large component. Current computer tomography (CT) scanners use application-specific integrated circuits (ASICs) that span a few square inches; this is quite big in comparison to other implementations of embedded systems which cover a mere fraction of an inch. Photodiodes are yet another embedded system that is critical to CT scanners. Photodiode arrays (photodiodes arranged in a linear fashion on an integrated chip) are responsible for detecting different wavelengths of light, a fundamental function in CT technology.

Sherpa Robot codename BigDog

The Sherpa robot (codenamed “BigDog”) is supposedly the most advanced four-footed robot in the world. The project is funded by the Defense Advanced Research Projects Agency (DARPA) and is being developed in cooperation with other agencies and organizations. Other DARPA-funded robot projects include that of the tree-climbing robot. The BigDog project aims to create a robot that could mimic animal movement, mechanics, control, and structure. The robot is being developed for the primary purpose of developing a robotic “pack mule” – a robot that can be used in a battlefield to carry heavy loads and go over rough terrain. Thus, this robot would function like a real animal that can carry the military unit’s supplies and ammunition. However, unlike real animals, the robot will not go hungry, become thirsty or get weary.

Embedded Electronics Technology in Automobiles

As automobiles become increasingly user-independent and ‘intelligent,’ the demand for embedded electronic devices for use in cars is steadily increasing. This was indicated by increased demand for printed card buses (PCBs) that were destined for use as embedded devices in automobiles. PCB production rose in several parts of Europe, and experts in the industry are predicting moderate growth worldwide in the near future. Embedded systems, because of their small size, low power consumption and rapid response rates have become valuable to the automotive industry as parts of safety components, sensors and on-board computers.   Virtual Mechanisms Powered by Embedded Systems Car manufacturer, Porsche, in cooperation with dSPACE of Germany, has developed an electronics system that simulates the forces at work when one shifts gears. The shift force simulator simulates the normal operating conditions of a car from a driver’s perspective. Available inputs include the gear stick and pedals. Data from those input methods are then fed into a computer, which calculates the appropriate type and amount of feedback to the user.

The Digital House

The development of new tech-based products and systems has given rise to new ways to do business. Moreover, continuous drops in prices of these products and systems as well as their increased versatility have made integration of traditional gadgets possible. Merging devices has resulted to flexible, multi-functional business and/or entertainment systems that are capable of sharing, retrieving, and transferring digitized information among devices – and they do so with utmost control, convenience and security. Digitized Home A new tech-based segment in the market is gaining more popularity in businesses and households because of its simple yet flexible applications; functions that could change the way people communicate, transfer information and enjoy the comforts of their home are being developed. Digital home is a term that refers to a system where data and information storage, sharing and transfer (using networks of various devices and computers) exist. It is usually comprised of three main components: the servers, the players, and the controllers.

The Autonomous Flying Ambulance

The autonomous flying ambulance, nicknamed the Mule, created Rafi Yoeli, who used to work for Boeing and Israeli Aerospace Industries. He later founded his own company, Urban Aeronautics, in Yavne, Israel. The Mule is the smaller version of another Urban Aeronautics product, the X-Hawk. The former vehicle has been designed to carry injured military personnel (hence the name “flying ambulance”) out of combat areas. At the same time, the latter is aimed at urban and personal use. Several of Yoeli’s patented inventions are integrated into the Mule, including his VTOL (vertical take-off and landing) vehicle technology and the hybrid drive-powered lift platform. Both the Mule and the X-Hawk, for instance, are classified as VTOL vehicles.

AVR reads button state and indicates on LED

This is a simple demo program of reading button state, lighting LEDs, sending information via USART. 8 buttons are connected to Atmega16 port A, 8 LEDs to port B via current limiting resistors. While none of the buttons aren’t pressed, there is running light on LEDs performed, but when any of the buttons are pressed, LEDs display the current 8 bit counter value in binary format. The same value is sent via USART – you can see a number in the terminal if connected. The program is very simple:

AVR analog comparator and avr-gcc example

Analog comparator is a pretty simple peripheral, but it can give big benefits. Comparator module is included in all Mega series of AVR microcontrollers. Simply speaking, Comparator allows comparing voltage values applied to two pins of microcontrollers. The comparison results are a logical level, which can be read by the program(ACO- Analog Comparator Output bit). There is also the ability to generate an interrupt, which depends on the comparator resulting level. And more- timer T1 can capture this level what allows measuring the signal length of analog signals. To use pins as comparator inputs, they must be prepared and configured as input(DDRx=0), and pull-up resistors must be disconnected (PORTx=0). In some models like Atmega48x/88x/168x, Atmega165x, Atmega325x,3250x,645x/6450x, and Atmega640x/128x/1281x/2560x/2561x, there is the ability to disconnect digital buffers of AIN0 and AIN1pins that allows the use of these pins only for analog signal input – this minimizes overall power consumption.
