WXR3031 rework station will replace you three devices
Posted on: 04 Nov 2016
Good soldering station is usually a fundament of a workplace. Desoldering station is usually a necessity if you work in development or service. And a hot-air station? – this one is becoming a must at any development or rework of PCBs with SMT components. If we already know, that it´s ideal to have all these […]
Terahertz Optical Transistors Beat Silicon
Posted on: 03 Nov 2016
PORTLAND, Ore.–Purdue University researchers have demonstrated a CMOS-compatible all-optical transistor capable of 4THz speeds, potentially over a 1000 times faster than silicon transistors. Nano-photonic transistors processed at low-temperatures can be fabricated atop complementary metal oxide semiconductors (CMOS) to boost switching time by ~5,000-times less than 300 femtoseconds (fs) or almost 4 terahertz (THz), according to […]
Using Efficient SPI Peripherals for Low-Cost MCU-Based IoT Designs
Posted on: 02 Nov 2016
Efficient Internet of Things (IoT) designs must balance a host of requirements that often work against each other. Low cost is important, but often supporting all the key features required by the application increases MCU pin count and memory size—two things that work against low cost. Low power is also important for IoT applications where […]
Wireless Transmitter System
Posted on: 01 Nov 2016
Summary This wireless project is a power transmission system, it works on the principle of magnetic induction. This Wireless Charging system works as the digital switched mode power supply with the transformer, which is separated into two parts: The transformer primary coil is on the transmitter, working as the transmitter coil, and the transformer secondary […]
Externally clocking (and overclocking) AVR MCUs
Posted on: 31 Oct 2016
People familiar with AVR boards such as Arduinos likely know most AVR MCUs can be clocked from an external crystal connected to 2 of the pins. When the AVR does not need to run at a precise clock frequency, it is also common to clock them from the internal 8Mhz oscillator. Before CPUs were made […]
Distance Measurement using Infrared Sensor with ADC0804 & 8051 Microcontroller
Posted on: 30 Oct 2016
Summary This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact distance is also calculated and displayed on a 16×2 LCD interfaced to the microcontroller. The IR receiver detects the IR radiations reflected by the object being […]
Circuit adds foldback-current protection
Posted on: 29 Oct 2016
For many applications that require power-supply currents of a few amperes or less, three-terminal adjustable-output linear voltage regulators, such as National Semiconductor’s LM317, offer ease of use, low cost, and full on-chip overload protection. The addition of a few components can provide a three-terminal regulator with high-speed short-circuit current limiting for improved reliability. The […]
Use an LM317 as 0 to 3V adjustable regulator
Posted on: 28 Oct 2016
Most engineers know that they can use an inexpensive, three-terminal adjustable regulator, such as Fairchild Semiconductor’s LM317, as an adjustable regulator to only some necessary value of voltage, such as 36 or 3V. This value cannot be less than 1.25V without employing other approaches, however. The devices’ inner reference voltage is 1.25V, and their output […]
Making the new silicon: Gallium nitride electronics could drastically cut energy usage
Posted on: 27 Oct 2016
An exotic material called gallium nitride (GaN) is poised to become the next semiconductor for power electronics, enabling much higher efficiency than silicon. In 2013, the Department of Energy (DOE) dedicated approximately half of a $140 million research institute for power electronics to GaN research, citing its potential to reduce worldwide energy consumption. Now MIT […]
Inside the Intel RealSense Gesture Camera
Posted on: 26 Oct 2016
The Intel® RealSense™ gesture camera represents another foray by Intel into the consumer products space. The camera has been incorporated into the Lenovo ThinkPad Yoga 15. Intel disclosed at IDF14 that the device is formed using three components: a conventional color CMOS image sensor camera, an infrared images sensor, an infrared light projector (the main focus of […]
