Introduction: Analogic Drawing Pad
In this tutorial you will learn how to create your own analogic drawing pad, something along the lines of an Etch a Sketch board.
Step 1: Parts
Step 2: Draw the Different Parts of the Pad on the Wooden Board
You will need to draw 10 pulleys in total. To draw the pulleys, just place them on the board and draw their contour.
Place de pulleys marked with “1” at 2cm from the sides of the board, and 5cm from the bottom of the board (the bottom of the board is the longest side).
Step 3: Lock the Pulleys to the Board, Using Screws and Bolts and Washers
Use 3 bolts in total for the small pulleys (the blue ones) and 5 bolts plus 2 washers for the big pulleys (the control pulleys -in red)
Step 4: Wrap the Nylon Wire Around the Blue Pulleys and the Control Pulleys
Step 5: Use Some Hot Glue to Stick the Ends of the Skewers to the Nylon Wire
If you’ve assembled all parts in the correct way, both skewers should be able to move freely around the pad (along the x and y axis of the pad).
Step 6: Create the Support for the Pen
We now need to create a support for the pen. Use a piece of cardboard to create it, then glue it to the other piece of cardboard hosting the skewers.
