Here's a creepy & cool halloween decoration you can make at the TechShop!

I made this using a really interesting halftoning technique & software from Jason Dorie.  

Let's jump right in!

  • 24" x 18" x 1/8" acrylic or other CNC-able, clear or translucent material. 
  • Black paint that will bond with your material
  • wood for framing, approx 1/2" thick.
  • opaque backing sheet.  MDF or similar.  Roughly the same size as the front piece
  • LED Light strip
  • Arduino
  • CNC Router
  • Table saw
  • Router rable

Step 1: Generate your CNC Files

Picture of Generate your CNC Files
The process is a little involved, but here's the outline:
  1. Open up the 'reactor' program.  Import your image into it.
  2. Let it run.
  3. Export the file
  4. Open up the Vectric software and import the image
  5. trace the image to covert to vectors
  6. create a pocket toolpath with all the vectors.
  7. If the tool fits into all the little pockets, YEAH.  Usuall it won't be right.  If it doesn't fit and create a good carving path, you need to scale down your source image, and go back to step 1.
Once you've created the carving path, you can move on to the hardware!


Just watched the video in the last step it looks fantastic lit up in the dark. well done Sir

Yeah, it does look pretty neat :-) Thanks!

It looks hard, how long did it take u again?..

Heh, I don't really know. A couple hours to do the design. A couple hours to do the CNC. And a few hours to build the box. Maybe 8 hours total? Oh yeah, and a couple hours to build the arduino stuff and get it running.

Do you know about this book then? http://www.amazon.com/gp/aw/d/1579129129?pc_redir=1
