Posted on January 29, 2014 by R-B Leave a comment

Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced a new power monitoring IC, the MCP39F501. This device is a highly integrated, single-phase power-monitoring IC designed for real-time measurement of AC power. It includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible two-wire interface. An integrated low-drift voltage reference in addition to 94.5 dB of SINAD performance on each measurement channel allows accurate designs with just 0.1 % error across a 4000:1 dynamic range.

Netduino car controlled through Windows phone

Posted on January 28, 2014 by R-B One comment

Matt Cavanagh, a Windows phone app developer from South Africa and the author of the Netduino Home Automation Projects book, built this Bluetooth controlled car using the Netduino board. He uses a Windows Phone to control the car over Bluetooth. The beauty of this project is that he 3-D printed the frame and wheels for the car. His next goal is to mount a second Windows Phone on the car and use Skype to stream the live video from the car.

chipKIT Project 3: Easy Pulse Meter

Posted on January 8, 2014 by R-B 7 comments

This is a third project in our chipKIT tutorial series and today we are going to construct a simple pulse rate meter using our Easy Pulse sensor with Digilent’s chipKIT Uno32 board. Digilent’s chipKIT Basic I/O shield is also used in this project for displaying the pulse waveform and the pulse rate.
