תצוגה ייחודית לסטטיסטיקות ישראליות

אני ואחי יצרנו תצוגה מעניינת לראות אירועים יום יומיים ישראלים . כמה כסף עיריית תל-אביב עושה מדוחות על חניות ? - כמה כסף מרוויח בנק הפועלים בשניה ? - כל כמה זמן נולד ילד במדינה ? / מישהו מתגייס ? / כמה שקיות במבה מיוצרות בשנייה ? ... ועוד ועוד. צריך לראות כדי להבין: תדירות ישראלית

Building a drawing robot in Geekcon 2015

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.
