10 Ways to Destroy an Arduino : Application Note ANCP01
Use a sledgehammer, fire a bullet at it, throw it into a pool....that’s not what we’re talking about. We’re going to show you how to electrically destroy your Arduino, though many of you seem to already know how to do that through unfortunate experience. You know what we mean....that funny smell, the scorch mark on a component, or the dreaded “programmer not in sync” error message -- all signs that you’ve just learned a lesson the hard way. Why are we doing this? If you own an Arduino, it’s good to know what is and what isn’t OK to do with it. Configure an I/O pin to be an output then set it high. Here is the path of current flow (the schematic is for the Arduino Uno, which can be found here):
EmoRate by AT
Future Applications EmoProfiles The list of potential applications for Affective Computing aka Computing With Emotions is incredible. As the technology develops people will develop EmoProfiles, profiles of their emotional reactions to videos, songs, books, reviews, anything and everything that sparks an emotional reaction (which basically is everything since we are emotional beings). The definition I have come up with for an EmoProfile: “An EmoProfile is a profile that contains data cataloguing your emotional reactions to various stimuli, tagged by keywords and other ontological aids and statistics, in a manner that allows one profile to be compared with another or a group of other profiles digitally by any reasonable computing device.” As adoption of EmoProfiles spreads they will become powerful tools for predicting what someone likes and dislikes, and how compatible people will be with each other and when interacting in a group.

MindFlex xbee eeg hack
Heyo guys, this is my last ultimate hack for the mindflex. I wanted to reproduced the results of the mindflex as indicated by the manufacturer.The simplest test that can be done with an EEG device is to check if the alpha waves go up significantly when closing your eyes. However doing some test with different subjects (i.e. my guinea pig students/friends) and with or without electrogel I couldn’t find any prove that the neurosky chip is working properly. So you take out of the shell 3 wires: black is the GND, blue is the Vcc=3.3V and white is the TTL signal at 9600 bauds. stream directly to the computer and one which uses a xbee transmitter and an xbee receiver. As I said before I totally desoldered the original radio modem that was on the main board inside, as in Figure. What can I do with that? Serial configuration The first configuration is the most dangerous one since you are connected to your computer via the usb without any opto-isolation so DO IT AT YOUR OWN RISK. XBee configuration
List of gear nomenclature
Addendum[edit] Principal dimensions The addendum is the height by which a tooth of a gear projects beyond (outside for external, or inside for internal) the standard pitch circle or pitch line; also, the radial distance between the pitch diameter and the outside diameter.[1] Addendum angle[edit] Addendum angle in a bevel gear, is the angle between elements of the face cone and pitch cone.[1] Addendum circle[edit] Internal gear diameters Root circle The addendum circle coincides with the tops of the teeth of a gear and is concentric with the standard (reference) pitch circle and radially distant from it by the amount of the addendum. Pressure Angle[edit] Apex to back[edit] Apex to back examples Apex to back, in a bevel gear or hypoid gear, is the distance in the direction of the axis from the apex of the pitch cone to a locating surface at the back of the blank.[1] Back angle[edit] Back cone[edit] Back cone distance[edit] Backlash[edit] Base circle[edit] Involute teeth Base cylinder[edit] Base cylinder

Arduino - BeJUG - The Belgian Java User Group
Abstract Arduino is a popular, open source electronics prototyping platform that is intended for artists, hobbyists, and anyone interested in creating interactive objects. It can sense the environment and affect its surroundings by controlling just about anything: light, motor, and more. This session will introduce you to Physical Computing, Arduino and how Arduino can be integrated with the Java platform. The session will include: An introduction to Physical Computing and Arduino How to develop Arduino applications A brief overview of electronics key principles How to integrate Arduino with Java Live demos to illustrate the various points This session is for anyone who wants to learn how they can, with just their Java skills, extend their applications to reach the physical world.

Twine. Listen to your world. Talk to the web.
Cloud Shield provides an interface for Arduino projects to talk to the Internet via Twine. Email, tweet, text message, text-to-speech phone call,* and send HTTP notifications that web applications can receive for all sorts of physical-web magic. It comes with an Arduino library and capacitive pads to trigger Twine actions with a line of code, your fingers or anything conductive. Prototypers, artists and designers use Arduino to execute their vision — an interactive installation, a product interaction prototype, logging user activity for field research. But networking is messy, and your time is better spent making your idea great. Twine makes it easier to give your things a voice on the Internet. Cloud Shield stacks on top of any Arduino board and connects to your Twine with the included 3' cable. *SMS and voice calls with a paid Twine account, coming in March.
