I've written about it before
but I manage a creative technology lab at California College of the Arts. I assist students with a wide range of skills, create a wide range of projects. One of many parts of my job is to show current and prospective students why these are valuable skills to learn. I can and do tell them that even a basic understanding of how to develop technology is going to put them above the pack as a designer. But this isn't a very entertaining argument. So, what is an entertaining way of getting them excited about electronics and technology development? Showing them projects that have only been made recently possible and blowing their minds!
This is one of the projects that I use to do this. Without touching anything, it allows you to control the functionality of a 3D printer (or anything that uses G-code). Without touching anything, you can control a machine. Waving your hand in the air, allows you to control a complex machine. That's some Tony Stark future stuff right there. Future stuff in the present moment.
