Tim Deagan has written for Make: magazine, Nuts and Volts, and other technical publications. He is a licensed Texas Flame Effects Operator and the Flame and Safety Coordinator for the Austin Mini Maker Faire. After years of building flame effects, aka "booshes," in the local Burn community, Tim began teaching classes called "Propane 101" and "Build Your Own Aluminum Foundry" to help other interested makers create their own projects. As a former firefighter in the Brent Volunteer Fire Department and captain of a Red Cross Disaster Action Team, Tim has always believed that the most exciting pursuits are at their best when safety is fully understood and becomes part of the culture. Tim is also a contributor to the open-source 3D CAD program OpenSCAD and an active member of the Handibot CNC and Printrbot 3D printer communities.
