INTRODUCTION

 (^) This project shows how to design and build low cost erasable whiteboard that could write and draw in real time via a web interface and therefore also from a smartphone based on the open source hardware and software.  (^) The iBoard is a web controlled whiteboard connected to the internet capable of writing texts and drawing with great precision. Also, it can erase in a quick and effective way.Send to iBoard your information from any part of the world.

ELECTRONICS

SYSTEM

The main electronic component required are :  (^) one Raspberry pi 3b  (^) Arduino uno  (^) a4988 Motor Driver Module with Heatsink.  (^) DC power supply(12v 3amp) ,  (^) Some wires, Relay, Servo.  (^) Stepper motors  (^) Raspberry is the main heart because it manages all the operations and the input and output signals.

PAGE 08 PAGE 09  (^) Arduino manages the current flowing into the motors and actuates a servo to move the pen and the eraser.  (^) The CNC shield aboard the Pololu drivers A4988 they operate the Nema 17.  (^) Arduino is powered directly from the Raspberry via a usb cable.  (^) Raspberry is the webserver on which it runs a site with the interface to write and draw then the SVG format is sent, always to the Raspberry that converts it into GCODE and processes it to operate the engines.

The software parts required for this

project are as follows:

 (^) PyCNC (engine and gcode management).  (^) Svg2gcode (convert from svg to gcode).  (^) Grecode (gcode manipulation).  (^) Easysvg (text generator in svg)  (^) iBoard.class.php (main control class).  (^) iBoard.js (client side javascript class that dialogs

 PyCNC

o (^) PyCNC is a free open-source high- performance G-code interpreter and CNC/3D-printer controller. It can run on a variety of Linux-powered ARM- based boards, such as Raspberry Pi.

 SVG2GCODE

o (^) A Command line utility for converting SVG to Gcode using Gcanvas and canvg.

 GRECODE

o (^) Grecode is a useful library that is concerned with remaining the Gcode, for example by moving the drawing to a specific coordinate, mirroring it, rotating it, scaling it, stitching it, and so on.

 EASYSVG

o (^) Easysvg is a PHP class that is always downloaded from GitHub that allows you to convert a text into SVG.

 CLIENT SIDE

 (^) Client side will have a jQuery-based HTML web interface that will allow the user to write text or draw hands- free with the mouse or with the smartphone's touch screen.
