  • 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.

  • The top of the board contains the sensors and the control/communication electronic: The JTAG/Serial connector permit to program the processor and to communicate debug messages. The Main CPU is a STM32 Cortex-M3. It is clocked at 64MHz from the internal oscillator. The 2 Axis X-Y Gyro is an invensense IDG500. It has an analog output and thus is connected to the CPU analog to digital converters. The 1 Axis Z gyro is an invensense ISZ500. As the X-Y gyro this is an analog chip connected to the CPU analog to digital converters. The 2.4GHz Radio is based on a nRF24L01+ chip from Nordic Semiconductor. It is actually a breakout board sold by SparkFun. The radio is connected to the CPU via a SPI port. The 3 Axis Accelerometer is a SMB380 from Bosch. It is connected to the CPU via an I²C bus.
  • Here nothing particular, except that the little battery is taped on the bottom of the copter. The battery comes from a Silverlit x-twin plane and actually permit 4.5min of flight time.
  • Under the battery we mostly have power supply and the “power” electronics: The charge connector accepts 5V and permits to charge the battery The power switch permits to power the copter either from the charge connector or from the battery. The 5V step-up permits to increase the power voltage from the 3~4V coming from the battery to 5V. The two 3.3V linear regulators, reduces the 5V to power the copter electronic. The digital and analog 3.3V are generated independently. This was made to reduce the noise on the analog components (here it is the two gyros, a quite critical part). Finally at the four sides we have the motors transistors. The power for the motors pass on the top and bottom of the part of PCB that hold the motors. It can be noted that we also have the battery charging chip just at the right of the 3.3V regulators. It is a classical MAX1555 and is working pretty well. The idea with the step-up was to get a more stable voltage when the battery is depleted and also to remove some of the noise coming from the motor electonic. Anyway, this boars is capable to work without by using 2.8V linear regulators instead. So most likely the step-up will be excluded on the next version and we also plan to integrate the radio on board. The motors and propellers are taken from a Silverlit X-twin plane. They are powered by the battery voltage.
  • The copter is controlled via a python program running on the PC. A Playstation bluetooth gamepad is used to pilote it.

'Anti-Facebook' project nears launch | Software, Interrupted - CNET News - 0 views

  • open-source social networking project Diaspora
  • if the team is half as good at building software as it is at building hype, there might be something interesting in the upcoming release, and maybe even a viable business.
  • The big challenge is that the enterprise developer world isn't screaming out for an open-source Facebook, nor are consumers really looking to run their own instances of social networks. What they really want is for Facebook to take privacy more seriously

  • And for those who do want to run their own social sites, there are any number of options, including Ning and Buddypress as well as extensions to Drupal and other publishing systems. Additionally, a number of other companies, including Ringside Networks, founded by JBoss alumni, took a run at developing a social application server only to find a lack of market.

Tor Project: Overview - 0 views

  • Overview
  • Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. Tor provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals use Tor to keep websites from tracking them and their family members, or to connect to news sites, instant messaging services, or the like when these are blocked by their local Internet providers. Tor's hidden services let users publish web sites and other services without needing to reveal the location of the site. Individuals also use Tor for socially sensitive communication: chat rooms and web forums for rape and abuse survivors, or people with illnesses.

Mini-bots cooperate to map out building interiors | Crave - CNET - 0 views

  • Mini-bots
  • map out building interiors
  • The rolling droids are being developed by Georgia Institute of Technology, the University of Pennsylvania, and the California Institute of Technology/Jet Propulsion Laboratory (JPL). Equipped with two cameras and laser scanners, they can autonomously explore hallways in an unfamiliar building, detecting doors and windows, and create a map for users such as soldiers or firefighters. The project is part of the Micro Autonomous Systems and Technology (MAST) program and is being sponsored by the Army Research Laboratory. The program is aimed at developing palm-size machines that can hover in place, enter buildings, and perform other insect-like stunts while gathering data and relaying it to human controllers.
