New Japan Radio’s improved reference voltage accuracy shunt regulator is suited for industrial or home applications NJR’s NJM17431 is an adjustable precision shunt regulator where the output voltage may be set to any value between VREF (about 2.5 V) and 36 V by two resistors. The NJM17431 features improved reference voltage accuracy and safety operating boundary area connected large capacitance. …
ITEAD has just released a new Zigbee 3.0 dongle powered by the Silicon Labs EFR32MG21 wireless MCU. The Shenzhen-based company, well known for its Sonoff line of home automation devices, had recently introduced a number of Zigbee compliant products like the Sonoff BASICZBR3 smart switch, the Sonoff ZBBridge WiFi to Zigbee Gateway, and the Zigbee-compatible USB dongle. ZigBee 3.0 USB …
Texas Instruments announced plans for the Regency TR-1, the first transistor radio to be commercially sold, on October 18, 1954. The move was a major one in tech history that would help propel transistors into mainstream use and also give new definition to portable electronics. TI was producing germanium transistors at the time, but the …

Broadcom’s BCM4389 chip is a client-side device supporting Wi-Fi 6E and Bluetooth 5 combo dedicated to mobile handset applications. The Wi-Fi 6E technology can operate on the 6 GHz band with 160MHz wide channels which is a progressive version of the Wi-Fi 6 technology. Hence, it enables speeds over 2 Gbps for faster communications than the Wi-Fi 6 that supports from 2.4GHz to 5GHz radio bands. …

STMicroelectronics’ long-range wireless and ultra-low-power devices embed a powerful ultra-low-power LPWAN-compliant radio solution STMicroelectronics’ STM32WLE5/E4xx long-range wireless and ultra-low-power devices embed a powerful ultra-low-power LPWAN-compliant radio solution, enabling the LoRa® (available in STM32WLx5xx only), (G)FSK, (G)MSK, and BPSK modulations. These MCUs are compatible with standardized or proprietary protocols such as LoRaWAN®, Sigfox, W-MBUS, and more (fully …
The concept of Software-defined radio is not new, it has been around for years. It is basically about moving complex signal handling over to a digital software platform via PCs and smart systems. While we have seen Artificial Intelligence already been implemented in a host of applications like speech recognition, gaming and autonomous vehicles, we are yet to see …

Introduction Our project is a resistor sorter that allows users to input multiple resistors, measure their resistance, and sort them into predefined bins or return them to the user. For a video of our sorter, please see our Project Demo. From the onset, we wanted to make a project that approached a realizable product where users …
A smart control knob and pan designed for the absent-minded chef! The Smart-O-Pan takes the constant vigilance out of your culinary creations, making cooking bdddoth simple and safe. I designed the smart-o-pan with people like my mom in mind. I was the family chef for a number of years but since attending university, she’s taken …
We designed, constructed and tested an autonomous quadcopter that used an IMU to control its attitude and a radio to transmit data to a controller, which we also built. The project focused on making the quadcopter as autonomous as possible, so only high level commands such as flight time are sent from the controller to …
