ZigUNO Zigbee development board comes with an Ebyte E18-MS1 module equipped with Texas Instruments SimpleLink CC2530 8051 Zigbee microcontroller and follows Arduino UNO form for Arduino Shield compatibility. The board works with PTVO Zigbee firmware that comes with a graphical configuration tool to select the Zigbee chip used (CC2530), configure I/O behavior (input/output, pull-up, etc…), and more.

This is Part 2 of a series of blogs regarding the development of a wall-mounted server based on the Raspberry Pi, featuring WiFi and a colour touchscreen. Part 1 can be found here. The enclosure I’m using, a re-purposed room thermostat casing, places some very tight constraints on the dimensions of the Raspberry Pi and

The capabilities of sensors and sensing systems have grown considerably in recent years, making data acquisition (DAQ) systems increasingly complex as the amount of data flowing and the processing required in these systems multiplies. FPGA devices are perfectly suited to high performance DAQ because of their flexibility, configurability, performance, and parallel processing capabilities. Data ingress

There are many Quadrotor Projects out there. But, they require a hobbyist to deal with the Frame Designing (Mechanical), a bit of Microcontroller knowledge as well as dealing with the Motor Control (Power Electronics). You may purchase a commercial Radio and a readymade Kit for flying. But, to Do-It-Yourself, is an achievement in itself. Here is
Arduino based Quadrotor on a PCB Continue Reading
While some decent lasers are out there for under $400 USD, they tend to be a little small. What if you wanted something a little nicer but didn’t want to jump to the $2,000 category? The answer for [Owen Schafer] was to build it with parts he had lying around and a few strategic purchases. While

The STTS22H temperature sensor from STMicroelectronics offers high accuracy with low operating and standby current and flexible operating modes. By Gina Roos @ electronicproducts.com STMicroelectronics has launched its STTS22H temperature sensor with typical temperature-reading accuracy of 0.25°C and low operating and standby current. The device enhances temperature and heat-flow monitoring in asset trackers, shipping-container loggers, HVAC systems, air humidifiers,

Drums are an exciting instrument to learn to play, but often prohibitive if there are housemates or close neighbors involved. For that problem there are still electronic drums which can be played much more quietly, but then the problem becomes one of price. To solve at least part of that one, [Jeremy] turned to using an
