I made this box for my pcom final project. It took me several days to finish the fabrication part.
This is a drawing machine. When it start working, servos will control a laser diode to draw sketch(the image is captured by Kinect), and you will find a laser point on translucent panel. Then you could draw on the panel by following the trace of laser.
This video shows how it works:
1.enclosure design & 3d model
Built a 3D model in Rhino to check the dimensions and make sure all the parts could fit perfectly.
2. prepare materials
3. measure and cut
I used band saw and milter saw to cut wooden boards(as well as acrylic board. Actually i should laser cut the acrylic if i have another chance).
I drilled a square hole for cable ( so hard to drill a nice square hole!)
I also drilled another hole for pencil sharpener.
5.stick boards with wood glue and drive in nails
6.drilled hols on the acrylic board.
At first, i planned to make the panel by saw and drill. However the board was so weak(1/16”) that it cracked when i drilled on it. So at last, i laser cut the panel instead and ground off the burning edge.
Made a box to collect pencil shavings.
Use chipboard to make a shelf to avoid pencils falling down from holes, and glued this shelf at the bottom of panel.
Made a support for servos.
Reorganized the circuit to make the interior space clean.
