Arduino Laser Tag - Duino Tag : Overview Overview Key parts of a duino tagger: IR Transmitter system What - Transistor amplifier, high power IR LED and a lens to give a well focused IR beam. Why - To give the tagger means of tagging / shooting other players as well as communicating game information. The transmitter amplifies the transmission signal from the arduino and transmits it using an IR LED, lenses are used to make the signal very directional in order to make the guns behave like guns and make long range transmissions possible. How to Debug C Program using gdb in 6 Simple Steps Earlier we discussed the basics of how to write and compile a C program with C Hello World Program.

Smalltalk Welcome to Smalltalk.org. Getting The Message The Essentials of Message-Oriented Programming with SmalltalkBy Alan Lovejoy. Smalltalk is a foundational programming language that is based on pervasive message passing, pervasive dynamic strong typing, pervasive reflection and pervasive object orientation. Message passing: Almost all computation in Smalltalk happens via the sending of messages.

The quadcopter : how to compute the pitch, roll and yaw After having introduced here the basics of an aircraft orientation and how to control it, this article is about actually computing the orientation of the quadcopter in space with sensors and with the Arduino. Which sensors to use? 3 axis accelerometer + compass for yaw To get easily the orientation of a non-moving object (pitch and roll), a 3-axis accelerometer (how does it work?) Microcontroller ARM Robot-R-Us Singapore Forgot your password? Forgot your username? C (programming language) C is one of the most widely used programming languages of all time, and C compilers are available for the majority of available computer architectures and operating systems. C is an imperative (procedural) language. It was designed to be compiled using a relatively straightforward compiler, to provide low-level access to memory, to provide language constructs that map efficiently to machine instructions, and to require minimal run-time support. C was therefore useful for many applications that had formerly been coded in assembly language, such as in system programming. Despite its low-level capabilities, the language was designed to encourage cross-platform programming.
11 Unusual Methods for Being a Great Public Speaker Prakash Panangaden taught me everything about public speaking. The first thing he taught me when we were in Kaiserslautern, Germany, for my “fascinating” talk titled “A Mechanically Assisted Proof in Category Theory” was ‘never go to the porn shops here. They will rip you off.’ I was 22 and Kaiserslautern was the worst city I had ever been to in my entire life. In a 24 hour period, I was chased by a lunatic, accused of stealing at the hotel I was staying at, kicked out of a bar for reasons I still can’t understand, and warned by my professor/mentor not to go to any porn stores or I would be ripped off. Being 22, I promptly ignored him.

RC Hobby Controllers and Arduino RC Hobby Controllers and Arduino Skill Level: Intermediate by NPoole | May 22, 2012 | 39 comments Programmers: Please don't ever say this to beginners ... Here's a sample interaction between an experienced programmer and a beginner who is just learning programming: Programmer: Hey, I hear you're learning programming. Cool, what're you learning? Beginner: I'm starting with some basic PHP and HTML using TextMate on my Mac. 100 Websites You Should Know and Use (updated!) Entertainment Meet David Peterson, who developed Dothraki for Game of Thrones There are seven different words in Dothraki for striking another person with a sword. Among them: “hliziﬁkh,” a wild but powerful strike; “hrakkarikh,”a quick and accurate strike; and “gezrikh,” a fake-out or decoy strike. But you won’t find these words in George R.
A Privacy Manifesto in Code: What If Your Emails Never Went to Gmail and Twitter Couldnt See Your Tweets? - Alexis Madrigal - Technology A new tool under development by Oregon State computer scientists could radically alter the way that communications work on the web. Privly is a sort of manifesto-in-code, a working argument for a more private, less permanent Internet. The system we have now gives all the power to the service providers. That seemed to be necessary, but Privly shows that it is not: Users could have a lot more power without giving up social networking. Just pointing that out is a valuable contribution to the ongoing struggle to understand and come up with better ways of sharing and protecting ourselves online.
