The OpenHardwareExG is a platform for ECG, EEG, EMG, ENG, EOG, and evoked potential applications. The OpenHardwareExG platform was originally developed as part of the eeg-mouse project. About the OpenHardwareExG project Project goals The main goal of the project is to build a device that allows the creation of electrophysiologic signal processing applications. In addition: […]

Every one in the metro cities like Kolkata, Delhi enjoying the luxuries of the metro train ever spared a thought about the train? No, then let me give you a brief idea about the driverless automatic driven and controlled train. But before that let us have a brief recall about types of metro automation. The […]

Texas Instruments says it is making, “high-accuracy measurement more attainable with the first current-sense amplifier to integrate a high-precision, low-drift 2 mΩ shunt resistor,” – the device can cut calibration effort, system cost, and footprint for test and measurement, communications load monitoring, and power supplies. For highly accurate measurements over a wide temperature range, TI’s […]

New 200mm fans EBM-Papst will cool down your devices while not making a lot of noise. Maybe you already belong to users of top-level fans from EBM-Papst. This time we bring you another hint for well-proven types – considerably powerful with a 200mm diameter. The types are: ● A2E200-AH38-01 – 9 blade fan with sickle-shaped […]

If your design contains Microchip’s MCP79XXX series RTC chips and you are running into troubles using them, this technical brief is intended to resolve several of the commonly-asked questions regarding developing stand-alone serial interface real-time clock/ calendar devices with MCP79XXX. Similarly, there’s also another application note from Microchip which provides detail assistance and guidance in […]

In the first part of this discussion, the features of ACS712 device were briefly discussed. Now we will use that theory to implement the ACS712 sensor to make a simple DC current meter. The analog output voltage from the sensor is measured through an ADC channel of the PIC16F1847 microcontroller. A voltage to current conversion […]

This is an electronic garage door opener designed around a SparkFun GT-511C1R fingerprint scanner. There is already a very good instructable by user nodcah that describes how to build almost this exact device, from which I took 99% of my inspiration. I’m posting this to easily share with my local makerspace, and for anyone who […]

Whether it´s necessary to operate a device in gloves, or you only wish the given push-button was sufficiently big and well visible, new series of round and square caps for series Multimec 5G will solve it. Well known Dutch producer of top quality switches – company MEC, comes with novelties in a form of relatively […]

EasyEDA is a unique cloud-based EDA tool, designed to give electrical/electronic engineers, educators, engineering students and electronics hobbyists an easier EDA Experience. The objective of this cloud based circuit design tool is to help designers move from idea to manufactured prototype by providing comprehensive data and collaboration tools for electronic design. It is suitable for all […]

Freescale have introduced a new range of 3-axis accelerometers offering high sensitivity at low power consumption. According to Freescale the FXLN83xxQ family is capable of detecting acceleration information often missed by less accurate sensors commonly used in consumer products such as smartphones and exercise activity monitors. In conjunction with appropriate software algorithms its improved sensitivity […]
