Thingiverse Introduction What is Arduino? Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It's an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board. Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs. Arduino projects can be stand-alone, or they can communicate with software running on your computer (e.g. Flash, Processing, MaxMSP.) The Arduino programming language is an implementation of Wiring, a similar physical computing platform, which is based on the Processing multimedia programming environment. Why Arduino? There are many other microcontrollers and microcontroller platforms available for physical computing. Inexpensive - Arduino boards are relatively inexpensive compared to other microcontroller platforms.
Drones Odd Copter » A Quadcopter Blog Bufferbloat I received the following question today from Ralph Droms. I include an edited version of my response to Ralph. On Thu, Jun 20, 2013 at 9:45 AM, Ralph Droms (rdroms) <rdroms@yyy.zzz> wrote: Someone suggested to me that bufferbloat might even be worse in switches/bridges than in routers. Ralph, It is hard to quantify as to whether switches or routers are “worse”, and I’ve never tried, nor seen any published systematic data. wouldn’t believe such data if I saw it, anyway. I don’t have first hand information (to just point you at particular product specs; I tend not to try to find out whom is particularly guilty as it can only get me in hot water if I compare particular vendors). You can go look at specs of switches yourself and figure out switches have problems from first principles. Feel free to write a paper! Here’s what I do know. Ethernet Switches: The simplest switch case is where you have a 10G or 1G switch being operated at 1G or 100M; you end up 10x or 100x over buffered.
Overview We're thrilled to announce the launch of Processing 2.0—the latest incarnation of the programming language, development environment, and online community that has grown dramatically since its debut in 2001. This new release builds on the versions of Processing that have been downloaded almost two million times. We invite you to download Processing 2.0 from www.processing.org. The Processing software is free and open source, and runs on the Mac, Windows, and GNU/Linux platforms. For the past twelve years, Processing has promoted software literacy, particularly within the visual arts, and visual literacy within technology. Processing seeks to ruin the careers of talented designers by tempting them away from their usual tools and into the world of programming and computation. The Processing 2.0 release focuses on faster graphics, new infrastructure for working with data, and enhanced video playback and capture.

Data protection and privacy authorities (other) Rctimer ArduFlyer 2.5 and all other brands of APM 2.5 Tutorials & Discussion Bluetooth to Android Tutorial This is a guide to using bluetooth with your ANDROID device not your PC, I have had bluetooth working at times with my PC but it is extremely flaky and IMO not worth the effort. There are currently two options for telemetry to connect to your APM mavlink data remotely, 433-915 Mhz radios or Bluetooth. 433-915 Mhz radios are the best option for complete control during missions, but there is a bit of setup involved and in some cases legal consideration with the frequencies depending where you live, and interference with some onboard components, these can all be mitigated but if all you want to do is change some parameters at the field, change flight modes and setup some simple missions then bluetooth is great for that and easy to place on your model. 1: Choosing a Bluetooth module. This will work too; 2: Connecting the Bluetooth Module to the FTDi adapter. FTDi -> Bluetooth Module GND -> GND 5V -> VCC TX -> RXD RX -> TXD
Cerowrt CeroWrt is a project built on the OpenWrt firmware to resolve the endemic problems of bufferbloat in home networking today, and to push forward the state of the art of edge networks and routers. Projects include proper IPv6 support, tighter integration with DNSSEC, and most importantly, reducing bufferbloat in both the wired and wireless components of the stack. The CeroWrt 3.10 series of builds include the following features and capabilities: Linux 3.10 kernel. Wiki: The most up-to-date information about the project Members
