Brazillian Class Creates Digital Board Game

A class in Brazil was given the assignment to make a board game. [Marcelo], presumably, heard his son lamenting how lame it was going to be if the board was just cardboard with some drawings on, and came to the rescue.

Working with the class, they came up with the rules of the game. We’re not certain what those are, but it involves a regular game board, a flashing light circle with numbers, and a fusion between Operation and one of those disease transmitters commonly found at the doctor’s office. You can try to puzzle them out from the video after the break.

The brains of the board is an Arduino with an external EEPROM for all the sound effects and other data needed for this construction. Everything is laid out on a beautifully done home etched PCB. It’s too bad the other side of the board isn’t visible.

We’re sure the kids learned a lot working with [Marcelo]. It would have been nice if a traveling wizard came to some of our earlier classes in school and showed us just how much cool stuff you can do if you know electronics.

The Most Immersive Pinball Machine: Project Supernova

Over at [Truthlabs], a 30 year old pinball machine was diagnosed with a major flaw in its game design: It could only entertain one person at a time. [Dan] and his colleagues set out to change this, transforming the ol’ pinball legend “Firepower” into a spectacular, immersive gaming experience worthy of the 21st century.

A major limitation they wanted to overcome was screen size. A projector mounted to the ceiling should turn the entire wall behind the machine into a massive 15-foot playfield for anyone in the room to enjoy.

With so much space to fill, the team assembled a visual concept tailored to blend seamlessly with the original storyline of the arcade classic, studying the machine’s artwork and digging deep into the sci-fi archives. They then translated their ideas into 3D graphics utilizing Cinema4D and WebGL along with the usual designer’s toolbox. Lasers and explosions were added, ready to be triggered by game interactions on the machine.

To hook the augmentation into the pinball machine’s own game progress, they elaborated an elegant solution, incorporating OpenCV and OCR, to read all five of the machine’s 7 segment displays from a single webcam. An Arduino inside the machine taps into the numerous mechanical switches and indicator lamps, keeping a Node.js server updated about pressed buttons, hits, the “Lange Change” and plunged balls.

The result is the impressive demonstration of both passion and skill you can see in the video below. We really like the custom shader effects. How could we ever play pinball without them?

Control Robots to Solve Puzzles in This Twitch-Style Robot Livestream

Robotics is a booming field that gets everyone excited, but when the talk comes to real life applications the response is a bit more tepid. Pundits tend to point to the “3 D’s”—dangerous, dirty and dull—but they often overlook a market with short term payoff: Entertainment. We are beginning to see some […]

6 of Our Favorite Drawbot Projects

Check out these awesome drawbot projects for creating your own robo-Picassos.

Explore relations between nations daily with News Globus

News Globus is an unusual physical interface that piques the curiosity of people and asks them to explore the world by the news putting in relation places of the world. It was designed by Bjorn Karmann, Charlie Gedeon, Mikio Kiura, Sena Partal wiring 20 regions to a Genuino board inside the sphere. When two regions are connected with the jack, the Genuino selects a country randomly from each region and queries the NY Times API for news containing both locations. A web server then selects a story and converts the headline and byline to a mp3 file which is played either from the headphone jack or the speaker at the base of the globe:

The shape of the globe is an interesting artifact from the past which was combined with modern technologies and online services. Instead of allowing people to hear the news of one place, the audio jacks bring to mind the metaphor of the phone operator to get people to discover surprising connections between places near and far from each other.

Check the video to see it working:

The project was developed during the Interaction Design Programme at CIID with the help of Massimo Banzi and Dario Buzzini.

Interfacing lcd with arduino

How to interaface lcd (4-bit interface) with arduino?

In this tutorial, we are going to discuss , how to interface lcd with arduino.

We are using 16*2 lcd, means it have two rows and 16 columns. Overall, we can display 32 characters.

16*2 LCD

Lcd have 16 pins, out of which six are connected to arduino. D4-D7 are data pins. RS, RW and EN pins are also there. RW pin is permanently grounded since we are writing to lcd.

Pin no 3 is connected to pot (10k) in order to change the contrast. Pin no 15 and 16 are for backlight.

Since lcd don't have any backlight.

Code:

// include the library code:

#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {

// set up the LCD's number of columns and rows:

lcd.begin(16, 2);

// Print a message to the LCD.

lcd.print("hello, world!");

}

void loop() {

// set the cursor to column 0, line 1

// (note: line 1 is the second row, since counting begins with 0):

lcd.setCursor(0, 1);

// print the number of seconds since reset:

lcd.print(millis() / 1000);

}

How to add library to proteus

In this post, we are going to discuss how to place library in proteus. As we all know that, there is no library of many components/ devices in arduino. We can add external libraries to proteus either provided by third party or written by an individual.

Basically, library consists of two files having extension .IDX and .LIB

We have to place these two files in the following directory:

C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\LIBRARY

If you are using 32-bit windows, then you to place file in Program Files. As there is no Program Files(x86) in 32-bit windows.

Download arduino library from the link given below:

Download from here:

Now extract this rar file. You have to place only arduino.idx and arduino.lib in library folder.

Proteus

Hope, you will enjoy the tutorial.

Stay tuned for more updates..
