I'm a technology designer and digital effects artist living in southern Oregon. I have held some interesting jobs throughout the years, including library technology trainer, starting a solar-powered coffee roastery, inventing 3D display technology, manufacturing 3D printers, and creating animated sequences for music videos.
Idea Propulsion Systems is a venue for my growing collection of interesting thoughts and ideas. Some of the postings are quick factoids, and some are master plans designed to change the world. Most are somewhere in between. Please contact me if you wish to re-post or otherwise share material you see here.
There is also a bookstore where you can browse through some of the books I have written. If you like the book's description and associated free content, consider buying the book for your makerspace, classroom, or personal projects library. :-)

Idea Propulsion Systems
This is a complete illustrated guide to making a clay-extruding 3D printer. The build files and software for the project are all available for free as an open source directory through GitHub: MMM-DIY
This 45 page digital book walks through all aspects of finding the parts, assembly, open source software, and trouble shooting. If you like the project and want to make one, please consider buying this digital book. It makes a great companion during the build and organizes the process from start to finish.
