Dunedin Makerspace
We spent tonight doing a guided build. We had two goals:
1) Learn how to take 3D pictures with one camera and the open source GIMP software.
2) Make our own funky anaglyphic glasses using Lee colour filters 026 (bright red) and 354 (special steel blue) and paper, cardboard, cheap sunglasses, or our Reprap printer!
Step-by-step instructions are here -> AnaglyphsPDF . GIMP software is available here -> www.gimp.org
I’ve finally uploaded the PDF of the slides I was using. Note the static image on the page about how the Microsoft Kinect gets depth information from the changes in how the dots are perturbed by objects. This was originally an animated gif. You can go to the original source for that if you like.

Here’s some references from the 3D printing talk:
First of all Thingiverse where you can find 1000s of things to build and make

The “reprap host” slicing application can be downloaded from reprap.org
http://www.reprap.org/wiki/Installing_RepRap_on_your_computer
you’ll need a working Java runtime to use it.
You need to download the config file for our working reprap from:
http://www.taniwha.com/~paul/reprap.properties
install it in ~/.reprap (or wherever else reprap host stores stuff on your computer). To slice:
always quit and restart reprap host between objects – put the resulting ‘.gcode’ file on a USB key and bring it in to print

There’s also a design guide to help you make stuff that prints well:
