New chipset completes Sony’s Altair Cellular IoT solution portfolio to address NB only and NB/2G applications Sony Semiconductor Israel (Sony), a leading provider of cellular IoT chipsets, announced the launch of the Altair ALT1255, a new low-power NB2 chipset. The ALT1255 is 5G ready, designed with an integrated SIM (iSIM), user MCU, rich application layer, and …
AppSens, a Norway-based medical technology manufacturer, designed ‘ECG247 Smart Heart Sensor‘ – a Bluetooth LE enabled wearable ECG sensor, powered by Nordic’s nRF52832 SoC, to detect irregular heartbeats. This device is a wearable electrocardiographic (ECG) heart monitor designed to detect atrial fibrillation and other major cardiac arrhythmias. Atrial fibrillation is the most commonly occurred cardiac rhythm disorder and is …

Introduction For our ECE 4760 final project, we designed, constructed, and tested a glove-operated system that dynamically simulates the classic toy, Etch A Sketch, on a TFT LCD screen. In deciding what to build, our team wanted to create a device that would utilize several of the technologies overviewed in the course, in a fun, …
Introduction We created an affordable Digital Oscilliscope and Function Generator that is able to plot and produce (at the same time) generated electric signals (voltage) changing over time along a calibrated scale. The device provides the basic Digital Oscilliscope functionality of plotting the varying voltage onto a desktop monitor, and the basic Function Generator ability …

Step 1: What we will need: CBDBv2 Evo Board ( or any other ESP8266 Board you may like but who has voltage/current measurement capabilities) INA21x – Current shunt monitor USB adapter (take a look here for more details about the USB Adapter) Li-Ion Battery Module 2 x 10 Ω /10 W resistors Connection wires – …
Introduction In this project, we demonstrate a real-time stock monitor that uses the popular ESP8266 Wi-Fi module controlled by a PIC32. We decided to build a fun device that fetches chosen stock prices in real-time and displays them on a screen. The goal was driven by a desire to create a PIC32 system that connects …
Introduction The inverted pendulum is an interesting case in the study of control systems because of its unstable nature. A pendulum is considered inverted when its center of mass is placed above its pivot point, meaning that its only equilibrium point is when its center of mass is directly above the pivot point. This is …
