Online Computer Science Courses
In its purest form, computer science is the research and development of technology that solves specific problems. Computer science has brought the world smart phones, GPS systems, the gaming industry and tablet computing, along with technological developments that assist government, industry and medicine. In addition to creating new technology, computer scientists also make improvements to existing technology and study the ways computers can make our lives easier. One can learn more about this field of study through several online computer science courses. As with any branch of science, computer scientists perform research that establishes new information. This research begins with known mathematical algorithms and computer theory, and strives to constantly redefine what technology can do for us. Most computer scientists work on a theoretical level, using technology to study technology. During the first two years of a standard 4-year program, students focus on the basics:

10 Free e-Books On Electronic Circuits The description of the book states, "For two-semester/three-quarter, upper-level courses in Electronic Circuit Design. A basic understanding of circuit design is useful for many engineers–even those who may never actually design a circuit–because it is likely that they will fabricate, test, or use these circuits in some way during their careers. This text provides a thorough and rigorous explanation of both analog and digital transistor-level circuit design with a focus on the underlying principles of how different circuits work–instead of relying completely on design procedures or “rules of thumb.” In this way, students develop the intuition that is essential to understanding and solving design problems." This book is written for students, practicing engineers and scientists.

Secret-Knock Gumball Machine One of the best things about exhibiting at Maker Faire is giving attendees a challenge. For the 2010 Maker Faire Bay Area, I decided to combine a past project of mine, a door lock that opens only when you give a secret knock, with a standard crowd pleaser: candy. The result was this Secret-Knock Gumball Machine, which tempted and tested the crowds at Maker Faire to guess the right rhythm and receive a treat. Since the knock was not terribly secret (I happily handed out hints), it distributed hundreds of gumballs over the event’s two days.

Charlieplexing LEDs with an AVR ATmega328 (or Arduino) Charlieplexing is an ingenius method for controlling many LEDs without using many microcontroller pins. You can turn on or off one LED at a time. To light more than one LED at a time, you can scan the LEDs by turning a sequence of them on and off really fast. The number of LEDs you can control is determined by this formula: N pins * (N pins – 1). For example, if you have 4 pins, you can control 12 LEDs (4 pins * 3 pins). If you have 2 pins, you can control two LEDs, which makes it a little silly to employ Charlieplexing, since you could simply connect each LED to an MCU pin and then to ground.

Kali Linux by Beginner Hacking - blog A part of beginners hacking blog, the post is a complete and well explained guide atleast for beginners. RGB Liquid Crystal Display Tutorial Step #2: PrevNext Now we will prepare everything to start connecting to the Arduino. Aquaponics – Online Temperature and Humidity This project is a part of the Arduino Data Acquisition and Control System described in the upcoming book Automating Aquaponics with Arduino. You can see a live version of this tutorial here: While this project is designed with aquaponics in mind, it does not require an aquaponic system, making it useful for other projects such as home automation. The included application is, therefore, bare-bones, making it easier to integrate into any other App Engine project. How It Works Every sixty seconds, the Arduino will test its connection to App Engine.

Difficulty: Easy My older son recently started school and needed his own desk for doing homework. I wanted to make something nicer than a simple tabletop with legs, and realized that I could also build in a bit of fun for when the homework is finished. Both my boys and I still had space travel on our minds from our summer trip to Kennedy Space Center.

Difficulty: Difficult My older son recently started school and needed his own desk for doing homework. I wanted to make something nicer than a simple tabletop with legs, and realized that I could also build in a bit of fun for when the homework is finished. Both my boys and I still had space travel on our minds from our summer trip to Kennedy Space Center. For this desk project, I decided to go with a NASA theme. I researched the Apollo Program as well as NASA's Mission Control Center, and designed my own console roughly based on those. I say "roughly" because the actual Mission Control does more monitoring than controlling, and isn't awash in the whiz-bang rocket noises young kids appreciate.

0 Motivation When I bought such a motor control shield recently, it came as a kit without any instructions. I could find the circuit diagram and list of parts on the Internet after some searching, but almost nothing on assembly and how to control it. Therefore I decided to create this page to share with the community what I learned so far. Official Documentation Connections Yet another laser cutter When my EPSON 830U decided not to work for me anymore (printing heads clogged) I thought I could make some use of the still working mechanics of the printer. It's based on a couple of stepper motors for both axis of motion (print head and paper feed). So I replaced the original power supply and drive electronics for an arduino board and an stepper motor driver from Adafruit industries. Now I could move the printhead anywhere on a page. Next step was to add a laser on the printhead and to control it using a PWM output from arduino (so laser power could be modulated from the computer).
