We designed this project to demonstrate how to use the digital LED strip, how to use our Atmega32u4 breakout board with the Arduino IDE and how to make a por-table battery powered project that runs off of AAs. This project is not too difficult, and can be finished in a day. Some soldering experience is good since 'free wire' sol-dering is a little more difficult than soldering to a PCB, but even beginners should be able to manage. We don't include a tutorial on using the Arduino IDE so its good if you've played around with the Arduino already.

Imagine creating a 3-phase wind turbine from a common, everyday roof ventilator along with some magnets and coils of wire. That’s what we’ve created for your study of wind technology. We chose the Whirlybird TM roof ventilator for several reasons.• First, it has great bearings that simply will not wear out under normal – and even severe – use. Without great bearings your wind turbine is always fighting friction that only serves to slow it down with the attendant loss of power.• Second, it can be easily constructed with common tools and without soldering or drilling.• Third, it can be used indoors and [especially] outdoors where your study of day-to-day and season-by-season wind never stops.• Fourth, it produces 3-phase power just like the commercial wind turbines, which allows you to study this marvelous electrical principle first hand by using your computer and the 3-phase Bar Graph Board to produce computer plots.• Fifth, you will be able to modify it in order to study the effects of magnetism and how you can optimize the mechanical components to produce maximum power.Here is what is included in the Whirlybird TM Wind Turbine Kit:• 12 Wire Coils • 16 Bar magnets • 1-6-position terminal block • 1-8” diameter round metal rotor disk • 1-8” diameter round Plexiglas stator disk • 1-5/16”, 7/8” long threaded rod extender • 1-5/16”, 1 1⁄2” long bolt • 10-5/16” flat washers • 3-1 “flat washers• Roof Ventilator not included

POWER PORTEnergy Harvesting Demonstrating and Experiment Kit - No Soldering, Grab Power from thin air

Energy Harvesting is the process of creating energy from external sources. It is also known as Power Harvesting or Energy Scavenging. The source for Energy Harvesting is ambient background, and it is free. For example, the environment contains large amounts of electromagnetic energy due to radio and TV broadcasts. The POWER PORT kit is a concept demonstrator and experiment platform for radio frequency (electromagnetic radiation), energy harvesting. Kit includes all necessary components and breadboard to construct an ambient power circuit capable of generating up to 1.5 volts. To complete the project, an antenna and ground wire are needed. These are available as an option (part # 32PPANT). Or you may construct your own using instructions provided with the kit

TEMPERATURE GENIEEver lost frozen food because your freezer stopped? The TC-2 kit would have saved you money. An alarm activates when the temperature reaches a critical point. Turn ceiling fans on automatically when it gets too hot. This kit gives you 100mA of output. Size: 2" x 1/4" Power requirement 6 to 15v DC.

Add this little kit to any or all of your telephones. When one phone is used, a red LED will light on the other extension. This lets everyone know when your computer modem is in use. Power requirement 9v DC. Size: 1.1" x .6"

BUSY PHONE LIGHT

Part No. 31ERTELLITE • Price $9.75

Use this kit in A-STABLE (continuous train of pulses) or in the MONO-STABLE (triggered time delay). Times circuits from nano-sec. to 30 min. Comes with variety of resistors and capacitors suitable for most ap-plications. Power requirement: 4.5 to 12v DC. Size: 9" x 1".

ELECTRONIC TIMER KIT

Part No. 31ERLG2 • Price $7.50

Turn anything on or off with light. Turns on at night, off at daylight automatically. As the light touches or leaves the sensor it delivers 100mA of output to run a relay. Size: 1.5" x 1.2". Power requirement 6 to 15v DC.

SWEET 16 TONE DECODEROPERATES THROUGH PHONE LINES, RADIOS OR SCANNERSThe Sweet 16 Tone Decoder detects (DTMR) “Dual Tone Multi-frequency” data (those sounds you hear when pushing buttons on your phone), and when each individual button is pressed it sends a unique voltage to the electronics on the printed circuit board which activates a circuit on or off. There are 16 different touch tones, 12 of which are on a normal phone; special key pads have 4 additional buttons (A, B, C, D). This decoder gives an output voltage for all 16 touch tones. The Sweet 16 Tone Decoder has on the printed circuit board one (1) relay and driver circuit. If you want to use all 16 you can build your own board with 16 relays and driver circuits on it, or to get fancier, use a flip-flop IC to achieve a “toggle” effect (push ON, push OFF), or a 555-timer to provide a timing effect (on for 5 minutes, then off — the choices are unlimited. Any one output may be connected to the onboard relay circuit. Size: 2.2" x 2.8".

A very interesting sound detecting robot kit. The robot has a sound sensor that enables the robot to respond to clpas in any direction. Turn the switch to “ON”, the robot eyes start flashing, plays “Do, Re, Mi ...” and turn right and left. The effective distance for the robot to respond is within 1 meter.
