NXP has just released its new PMPB40SNA, a 60 V, 40 mΩ N-channel automotive MOSFET in a compact 2 x 2 mm DFN2020MD-6 (SOT1220) package. The DFN2020MD-6 is an industry first, featuring 100% wettable and therefore solderable flanks (side pads). This makes soldering and inspection much easier and is aligned with the automotive optical solder inspection requirements! It is the […]

The AD8232 is an integrated signal conditioning block for ECG and other biopotential measurement applications. It is designed to extract, amplify, and filter small biopotential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement. This design allows for an ultralow power analog-to-digital converter (ADC) or an embedded

A friend gave me one of Adafruit’s circuit playgrounds (developer edition) to use, and I wanted to see would it make a good robot controller. The circuit playground is packed full of features like sensors, neo-pixels and even an accelerometer. I wanted to add a L9110 motor controller and create a small bot I could

We always need to see the temperature and humidity when we sitting in our house to know whether we need to turn on/off AC, heater,cooler,etc. So here we have build this circuit to display temperature and humidity on the 7-segment displays, and we have used DHT22 to bring out the temperatures and humidity and a

This Instructable covers the assembly of a circuit capable of PWM-ing (pulse width modulating) a high-power RGB LED strip and programming an Arduino to cycle through a range of colors. In this context, “high power” is 9-12 volts. I will discuss how to mount a transistor to a heatsink and assemble the circuit. I will

Electric vehicles (EVs) are something of a hot topic, and most of the hacks we’ve featured regarding them center on conversions from Internal Combustion to Electric. These are all fine, and we hope to see plenty more of them in the future. There’s another aspect that doesn’t get covered as often: How to charge electric vehicles- especially
