Description The LTC4151 is a high side power monitor that operates over a wide voltage range of 7V to 80V. In default operation mode, the onboard 12-bit ADC continuously measures high side current, input voltage and an external voltage. Data is reported through the I2C interface when polled by a host. The LTC4151 can also

Introduction The trend in automobiles and industrial systems is to replace mechanical functions with electronics, thus multiplying the number of microcontrollers, signal processors, sensors, and other electronic devices throughout. The issue is that 24V truck electrical systems and industrial equipment use relatively high voltages for motors and solenoids while the microcontrollers and other electronics require

Abstract—This paper discusses the essential steps taken to achieve a low-EMI prototype before conducting compliance tests in an anechoic chamber. These steps include electronic circuit design for minimal radiation, and pre-compliance inspections. The pre-compliance inspections include simulated EMI analysis of a printed circuit board (PCB) layout model using 3DEM software, and a near-field EM scan

Introduction It all started two years ago when I first found this thing called an Arduino. I had seen some projects online people had made with one, so I impulse bought an Arduino UNO, knowing nothing about what it was or how it worked, but only that I wanted to learn. As soon as it

For makers, engineers, and DIY enthusiasts, Shenzhen, China is a bit of a dream world. Once you get past the shoddy internet and questionable origin of the components you buy in the markets, you realize just how quickly and easily you can get almost anything done. For about $100 you can get a couple dozen

In the current market where capacitive touch screens, resistive touch screens, TFT displays are flooding, DIY enthusiasts have been rarely used dot matrix screens. Here we use 5mm 8 * 8 dot matrix screen and phototransistor to achieve a pen write function. Sounds fun? But how to specifically make it? Can we achieve a larger

Already at the age of 12 I was dreaming of making a machine which could make things! A machine which would give me the opportunity to create products for in and around the house. Two years later I stumbled ont the words ‘Computer Numerical Control’ or more specifically the CNC milling machine. After I found
