Ampere

The ampere (SI unit symbol: A), often shortened to amp, is the SI unit of electric current[1] (quantity symbol: I,i)[2] and is one of the seven[3] SI base units. It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics. Note that SI supports only the use of symbols and deprecates the use of any abbreviations for units.[4]

A particle carrying a charge of 1 coulomb and passing through a magnetic field of 1 tesla at a speed of 1 meter per second perpendicular to said field experiences a force of 1 newton, according to the Lorentz force law. As an SI derived unit, the tesla can also be expressed as (in SI base units).[3] Units used: A = ampere C = coulomb kg = kilogram m = meter N = newton s = second T = tesla V = volt Wb = weber [edit] Electric vs Magnetic Field

The difference between magnetic field strength (in tesla) vs electric field strength can be confusing.[citation needed] The difference is that a force of magnetic field on a charged particle is generally due to the charged particle's movement[4] while the force imparted by an electric field on a charged particle is not due to the charged particle's movement. This can be seen by looking at the units for each. Electric field is N/C, while magnetic field (in tesla) can be written as N/(C*m/s). The difference between the two is m/s, or velocity. This can further be seen by noting that whether a field is magnetic or electric is dependent on one's relativistic reference frame (that is: one's velocity relative to the field).[5][6] In ferromagnets the movement creating the magnetic field is the electron spin[7] (and to a lesser extent electron orbital angular momentum). In current carrying wire (electromagnets) the movement is due to electrons moving through the wire (whether the wire's straight or circular).

The U49325 Sun Runner Stirling Engine is a solar-powered Stirling Engine which offers a dramatic demonstration of energy conversion.   This motor and its parabolic mirror can be attached to any conventional camera tripod. When properly aimed at the sun, the polished aluminum parabolic mirror focuses incoming solar energy on the heat cap of the engine, which is converted to rotary motion. Unit comes complete with motor, parabolic mirror, and wrenches. Standard camera tripod is not supplied. This engine is completely assembled and ready to run. Each unit is test run at the factory prior to shipping. Motor runs at 2,000 RPM and up. This engine can also run as a horizontal engine with an alcohol burner. Demonstrate this exciting method of harnessing the sun’s clean and renewable energy to your students.  Weight: 6.00 lbs Dimensions: Engine: 8.25 x 3 inches (L x W) Flywheel: 3.25 inchesParabolic Mirror: 18 inch diameterPlease note that this item is designed to demonstrate the operating principles of a Stirling engine for educational use and is not designed for power production.  It can potentially be coupled with a generator for producing very small amounts of electricity but is incapable of powering anything beyond a small light bulb or LED.

The unit is light weight (2.5 lb), portable, low cost ($10-$20) and can be used to recharge single cell batteries at from 1-3.5 amps. It can be made from a cordless electric drill in a primitive environment. The simplest way of how to make a hand crank DC generator using a standard 12, 14.4 or 18 Volt Cordless drill

With no modification hook an alligator clip jumper to the two charging terminals (on the bottom that the battery plugs into). See picture below. Note that when a 14.4 Volt drill is laid down pointing to the left then the upper terminal is most likely to be the plus and the lower terminal the minus for these units.

The copter itself is organised around the main CPU. The job of this CPU is to acquire the physical measurement given by the gyroscopes and accelerometers and to control the motors to keep the copter stable. This is done by a regulation loop which controls the motors speed 250 times per second. The radio communication has a pretty low bandwidth and is used to send commands to the copter and receive telemetry data from it. The CPU program can be updated by radio.

The computer runs control and telemetry programs. The control program reads the input from a game-pad and sends control commands to the copter. We also have programs that can configure the copter regulation parameters and log the measurements in order to make easier to tune the regulation. All the development is done on Windows and Linux. Indeed we are 3 to work on this project, two of us work on Linux and one is mainly on Windows. Using FLOSS permit to handle that in a very effective way. We are mainly using the GCC compiler from CodeSourcery for the copter program compilation, GNU Make for the project build, Mercurial for the source control, and python/pyusb for the communication with the copter. All these softwares works seamlessly on both Linux and Windows and made the project pretty easy to handle. The distance between the motors (horizontally and vertically) is around 8 cm and the total weight is around 20 g.

Arduino Ethernet is a collection of libraries I have written to use within the Arduino programming environment in conjunction with the Ethernet shield. While the individual libraries are downloaded within a single archive, they do not depend on each other (unless noted otherwise) and can be used independently. The libraries are published under the GPLv2 (or, at your discretion, any later version). Individual libraries EthernetBonjour | Documentation EthernetDHCP | Documentation EthernetDNS | Documentation Also, by popular demand, I've prepared a very simple demo sketch using DNS, DHCP and Bonjour together. Basically, it gets network configuration data via DHCP, then lets you resolve DNS names via the DNS server received from DHCP, all while announcing its DHCP-assigned IP address via link-local Bonjour — Basically a combination of examples from the individual libraries, which I also recommend to look at, as they contain lots of comments explaining how stuff works.
