Xbee and Arduino sent to space by NASA

XBee-Arduino-Nasa-4

Last July 7 at Wallops Flight Facility, NASA launched Black Brant IX , a suborbital sounding rocket to test “wireless-in-space” with XBee and Arduino :

Onboard the rocket was an experiment testing Exo-Brake technology. XBee was used to collect sensor data including temperature, air pressure, and 3-axis acceleration parameters. NASA is considering Exo-brakes as a possible solution for returning cargo from the International Space Station (ISS), orbiting platforms or as possible landing mechanisms in low-density atmospheres. This was one of many tests used to analyze its effectiveness, but the first to incorporate an XBee connected sensor network. If you would like to read more about the Exo-brake, check out this article.

As part of a program to determine potential applications of wireless technologies in space, NASA chose XBee® ZigBee modules and Arduino Mega  explaining that:

Wireless sensor technology allows measuring important parameters such as aerodynamic pressure and temperature at the apex of the Exo-Brake during re-entry. It is very difficult to instrument a deployable parachute like the Exo-Brake, and wireless sensor modules provide the means for this type of measurement where it is difficult to run wires,” said Rick Alena, computer engineer at NASA Ames.

XBee-Arduino-NASA-6

The NASA team constructed a gateway using an Arduino Mega, XBee, and Iridium module. The Arduino Mega was used to manage communications between the local XBee wireless network and the long-range Iridium satellite uplink. It was chosen as part of a NASA initiative to use commercial off-the-shelf components where possible, and to employ rapid prototyping tools to efficiently explore new ideas.

See the diagram below to get a detailed view into how the network was configured.

TinySensor server

Steve’s TinySensor server project, that is available at Github:

Well after almost a year I decided it was time to update this project with improvements to both its hardware and software.
On the hardware side, the server is still the original Raspberry Pi model B, but I’ve mounted the nRF24L01+ radio on a neat little Slice of Pi board. (These boards also have traces for mounting XBees with their unusual pin spacing. And they’re cheap!)

Wireless (Hacking Commodity Wireless, Practical Wireless, Contiki OS, CWIG)

via OSHUG

At the fifteenth OSHUG meeting we'll be taking a look at wireless technologies. We will hear how you can repurpose low cost commodity equipment, we will be given an introduction to RF basics, we will learn about the Contiki operating system, and we will be introduced to Ciseco's new Wireless Internet Gateway.

Hacking Commodity Wireless

Many people build their hacks from the ground up, but those short of time sometimes prefer to repurpose cheap off-the-shelf components that can be made to fit the bill. A good example being a wireless thermometer for external use, where an off-the-shelf device provides an inexpensive option complete with the requisite weatherproof packaging. However, such devices typically use proprietary protocols and good documentation is rarely available. This talk will look at how to interface such devices where a degree of reverse-engineering is frequently required.

Paul Tanner is a consultant, developer and maker in wood, metal, plastic, electronics and software. His day job is IT-based business improvement for SMEs. By night he turns energy nut, creating tools to optimise energy use. Paul graduated in electronics and was responsible for hardware and software product development and customer services in several product and service start-ups, switching to consulting in 2000.

Practical Wireless

Adding wireless connectivity to your latest open hardware project is not difficult, provided that you take the time to understand some of the principles of RF communication. In this talk we will learn about the basics of wireless propagation, and take a look at some of the low cost modules which now make adding wireless even easier.

Ken Boak joined BBC Research Department after graduating and worked on digital picture processing of HDTV images, and coding algorithms for video distribution around studios. Since then, Ken has worked in laboratory instrumentation, telecommunications, low power wireless and consumer electronics produced in the Far East. With an interest in renewables, Ken now develops laboratory instruments to teach undergraduates the principles of photovoltaic and wind power. Outside of work, Ken is interested in smart wireless sensors, open source hardware and low cost solutions for the Internet of Things.

An Introduction to the Contiki O/S

This talk is aimed to introduce the Contiki OS and some of the development hardware. We will learn about the process of bootstrapping the development environment and there will be a hands-on tutorial.

Ilya Dmitrichenko was born in Soviet Latvia in 1985, grew up and attended a secondary school there, and moved to UK as soon as Latvia joined the EU. He attended the biggest university in London and was rather disappointed with the education, but nevertheless carried on and had fun working on a final year engineering project which served as an introduction to the topic of this talk. Ilya is interested in various aspects of hardware and software, spanning from WSN to DSP and several other random fields.

CWIG — The Ciseco Wireless Internet Gateway

The CWIG is a new open hardware device that is designed to be the "one and only" platform you'd need for a wireless gateway. It employs the same ATmega328 microcontroller that is familiar to Arduino users and supports Ciseco's TI CC1110-based XRF module, XBee, Bluetooth, RFM12B, X10/HomeEasy, FRAM, SD, Ethernet and over-the-air programming with AVRDude. It's sized to be housed in a low cost, compact enclosure and to be cheap to build using through-hole components. In this talk we will be given an introduction to the CWIG and also to the XRF wireless UART and programmable RF module.

Miles Hodkinson's twenty-odd year relationship with IT ended around six years ago when he decided that it was time to do something completely different. He had looked around without success for something to log and control his wind turbine, solar panels and Lister single cylinder engine, and found that nothing was flexible enough for the money he wanted to pay (tens of pounds per device), so he decided he would try and build it himself. After a number of years working on a human-focused method of networking originally built using XBee modules and now termed LLAP, his company developed the TI CC1110-based XRF module.

Note: Please aim to arrive for 18:00 - 18:20 as the talks will start at 18:30 prompt.
