&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
I am an engineer intent on helping with the expansion of the production frontier of humans in all directions possible.&lt;br /&gt;
&lt;br /&gt;
I can most often be found lurking around the 3D printer and CNC mill around noon or after 5PM, or at project-specific meetups.&lt;br /&gt;
&lt;br /&gt;
I tend to be very focused on what I'm working on at a given moment, so just give me a direct heads up if you need a hand with something or if I'm interfering with your activities one way or the other.&lt;br /&gt;
&lt;br /&gt;
If you need help with structures, mechanics, electronics, manufacturing techniques, CAD, agriculture, microcontrollers, or related fields I might be able to help.  Below is a rough list of projects I'm working on or would like to work on, some with links.&lt;br /&gt;
