Hydroelectric turbine generator model http://www.deviceselectrotechnica.com/hydroelectric-turbine-generator-model.htm Mon, 09 Mar 2015 00:00:00 +0530 Most machines that make electricity need some form of mechanical energy to get things started. Mechanical energy spins the generator to make the electricity. In the case of hydroelectricity, the mechanical energy comes from large volumes of falling water. For more than 100 years, the simplest way to produce the volumes of falling water needed to make electricity has been to build a dam. A dam stops the natural fl ow of a river, building up a deep reservoir behind it. However, large dams and reservoirs are not always appropriate, especially in the more ecologically sensitive areas of the planet. For making small amounts of electricity without building a dam, the small-scale hydroelectric generator is often the best solution, especially where fast-fl owing streams on steep slopes are close by. A small-scale hydro system usually consists of an enclosed water wheel or turbine, which is made to spin by jets of high velocity water. The water is taken from the stream and moved down slope to the turbine through a long pipe called a pen-stock. Water fl owing through the pen-stock picks up speed, and is directed at the blades of the turbine by nozzles. The turbine spins continuously, as long as there is water to drive it. The turbine is connected to an electrical generator, and the electricity is then available for running appliances or charging batteries. The spent water is returned to the stream. This kind of system is called a “micro-hydro” system, “run-of-stream hydro” or “low-impact hydro.” XBee USB adapter(CP) + XBee module http://www.deviceselectrotechnica.com/xbee-usb-adapter-cp-xbee-module.htm Mon, 08 Jun 2015 00:00:00 +0530 Description: This is a simple to use, USB to serial base unit for the XBee line. This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro version. Plug the unit into the XBee Explorer, attach USB cable, and you will have direct access to the serial and programming pins on the XBee unit.The board also has an CP USB to Serial chip on it, meaning you can connect it to your computer via USB.The CP is connected such that you are able to reprogram the XBee modules to change the firmware. The board is powered by the USB cable.This board come up with the XBee XB24-Z7WIT-004 module from Digi. The new Series 2B improves upon the power output and data protocol of the Series2. Series 2B modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.
