December 2011 Competition

Hello Readers

It’s that time of the year again so we are running another competition. First let’s look at the prizes, then review the rules of entry.

— *** Prize One *** —

Prize One consists of the eleven modules from the new Freetronics Module/Sensor range, as reviewed recently:

With this range of modules you will be able to sense temperature, humidity, magnetic fields, light and sound pressure levels, sound and shock. Plus light up with the RGB LED, get more I/O with the expansion module, interface with the level shifter board, control high currents with the N-MOSFET, and power the lot with the tiny switch mode power supply. Available from Freetronics or a reseller near you.

— *** Prize Two*** —

Prize Two consists of one Freetronics EtherTen:

This is the mother of all Arduino-compatible boards. Designed in Australia and manufactured to the highest quality standards the EtherTen replaces three boards – consider having an Arduino Uno SMD, Ethernet shield with PoE, and a microSD shield – all on the one board. From the Freetronics website:

The EtherTen is a 100% Arduino compatible board that can talk to the world. Do Twitter updates automatically, serve web pages, connect to web services, display sensor data online, and control devices using a web browser. The Freetronics EtherTen uses the same ATmega328P as the Duemilanove and the same Wiznet W5100 chip used by the official Arduino Ethernet Shield, so it’s 100% compatible with the Ethernet library and sketches. Any project you would previously have built with an Arduino and an Ethernet shield stacked together, you can now do all in a single, integrated board.

We’ve even added a micro SD card slot so you can store web content on the card, or log data to it.

All the good things about the Eleven and the Ethernet Shield have been combined into this one device so please see those pages for all the specific details, but the highlights include:

  • Gold-plated PCB.
  • Top and bottom parts overlays.
  • Top-spec ATmega328P MCU.
  • Mini-USB connector: no more shorts against shields!
  • D13 pin isolated with a MOSFET so you can use it as an input.
  • Power-over-Ethernet support, both cheapie DIY or full 802.3af standards-compliant.
  • Ethernet activity indicators on the PCB and the jack.
  • 10/100base-T auto-selection.
  • Fully compatible with standard Ethernet library.
  • Reset management chip.
  • Fixed SPI behavior on Ethernet chipset.
  • Robust power filtering.
  • Sexy rounded corners.

Note that just like our Ethernet Shield with PoE support, the EtherTen provides a number of options for different Power over Ethernet. You can use the supplied jumpers and feed 7-12Vdc down the wire for cheap DIY version, or you can fit our PoE Regulator 24V and feed a bit more voltage down the wire, or you can use our PoE Regulator 802.3AF along with a proper commercial PoE injector or switch. It’s up to you.  Available fromFreetronics or a reseller near you.

— *** How to Enter *** —

There will be six questions for you to answer spread across articles published in December. At the end of December and once you have answers to all six, email the answers along with your full name, email address and postal address to competition at tronixstuff dot com with the subject heading December. During the second week of January, all the correct entries will be collated and two randomly chosen. The first correct entry drawn will receive prize one, the second correct entry drawn receives prize two. Entries will be accepted until 05/01/2012 0005h GMT.

As with any other competition, there needs to be some rules:

  • Incomplete entries will be rejected, so follow the instructions;
  • The winners’ entry, first name and country will be announced publicly;
  • Entries that contain text not suitable for minors or insulting to the competition will be rejected (seriously – it happens);
  • Prizes will be delivered via Australia Post domestic or regular international air mail. We take absolutely no responsibility for packages that go missing or do not arrive. If you live in an area with a “less than reliable” domestic postage system, you can pay for registered mail or other delivery service at your expense.
  • Winners outside of Australia will be responsible for any taxes, fees or levies imposed by your local Governments (such as import levies, excise, VAT, etc.) upon importation of purchased goods;
  • Prizes may take up to 45 days to be received;
  • If you have met John Boxall in person, or you have won a previous competition you cannot enter;
  • No disputes will be entered in to;
  • Prizes carry no warranty nor guarantee – and are to be used or abused at entirely your own risk;
  • Entries will be accepted until 05/01/2012 0005h GMT.
