Underdog at GeekCon

On the last GeekCon 2015, me and my brother built a drawing robot.

Can draw on a large scale pages, basically working the same way Logo (Computer Language) Turtle is working. Can go forward, backward and turn around. Can raise the pen or lower it in order to start drawing.

Here are some pictures, explanations and code.

We used the Arduino Uno (actually Funduino Uno compatible) over a Maze car  rack bought in Deal Extreme. Using the Keyes L298 driver for the DC motors and a Servo motor using the original Servo.h library kit from Arduino.

Cellular Grid Computer - GeekCon 2008

In GeekCon 2008 we have created the Cellular Computer Grid - creating a large computer to calculate PI using a grid computer made by cellular phones. The whole project was written in Java, both side, server and client on the cellular as j2me.

The project was created by Assaf, Ori and Myself.

Read more about the Giant Super Computer made of the public Cellular Phones in my blog and watch the movies from the demonstration.
