There are many CAD developed to assist the electronic designers during drawing of PCBs and schematics; often they are integrated in complete suite to project, simulate and realize a whole electronic system. Besides the many commercial versions, there are also free CADs available. Today we’d like to analyze one of the most diffused and known

Hi, this is my first instructable and I hope to do more. This project was for ‘Creative Electronics’, a Beng Electronics Engineering 4th year module at the University of Málaga, School of Telecommunications. http://www.etsit.uma.es/ It’s a cnc using Arduino UNO R3 , GCode Sender and GRBL. The cnc is made of wood thanks to the
I needed a small, fast and reliable multi-voltage level translator (mainly for connecting ESP8266 boards to the Arduino, got tired of resistor networks pretty quickly) so I built a breakout board for TI’s LSF0204(D). Datasheet and info here. The LSF0204 is a nice little chip. It can translate up to 4 signals to and from the

“Part Fill” Valve? Yes, Part Fill valves are widely used in Rainwater tanks. The valve will open once the water level in the tank has fallen to a low position, this allows the town mains water to enter the tank and, when the water level reaches the minimum level, the valve closes. This arrangement is

Analog channels A2 to A5 on an Arduino Uno are used to measure four different voltages. The measured voltages are displayed on a 16 character by 2 line LCD. The four channel Arduino multimeter can measure four independent DC voltages that can each be in the range of 0 to 50V. Voltages are displayed with

Linear Tech is aiming at high-impedance sensor transimpedance amplifiers with an op-amp that requires only 3fA of bias current (typical at 25°C) while offering 500MHz gain bandwidth product. Potential applications for the chip, called LTC6268, include interfacing ADCs to reverse leakage (linear) mode photodiodes. 20kΩ transimpedance gain is available at 65MHz, and 499kΩ with 11MHz
Sub-picoamp input op-amp offers high gain bandwidth Continue Reading
The games market may well dwarf the music and movie industries combined in global revenue and new-release games offer lighting effects and texture detail that make you forget you’re in a game and not a movie. But there’s always something that tugs us back to retro gaming – the blocky graphics corny 8-bit sound and

Motor control is becoming the power industry’s fastest changing technology area. The reason for this is the requirement to improve energy efficiency from the millions of motors which are used in our homes, factories and cars. New developments in motor controller design, current sensing and control algorithms will be needed if new and more stringent
New energy efficiency rules will change motor control design Continue Reading
