Started the New Rivery Valley Rocketry, high power rocket club here in Blacksburg VA. We hold high power rocket launches, with FAA clearance to 10k ft several times a year, and many more low/medium power community launches, and regular group meetings at the VT Aerospace department at VT's Elustrious Corporate Research Center. Our group became a Tripoli Rocketry Association Prefecture (#143) in 2012, and have regular VT Aerospace student, and NASA/USLI related launch events with the related students. Our group also does various community, public/private school, and Boy Scout outreach and S.T.E.M. related events and activities. Here's out Facebook Page and a link to some of our really cool big launch photo and videos!
Wrote and delivered three high tech home schooling classes for the local NRVCHE home schooling group. The classes were divided into ten, two hour classes designed for 8-11yr olds and 12-16yr olds. The classes were designed as a lead in to computer science/engineering type cirriculum (since home schoolers don't get a lot of high quality, CS/Engineering type material), and focused on the three subjects of:
1998-2006: Started the Gateway Church Mobile Soup Kitchen. Twice/month I cook food for 60-80 people, meet other volunteers at our local church, and coordinate our ministry under a downtown bridge to feed the homeless and minister to spiritual needs.
1997-2010: President of the local computer user group XCSSA (X-otic Computer Systems of San Antonio). We explore OS' ranging from Linux and Solaris, to BeOS and AmigaOS. We meet once/month for a high-tech show-n-tell, have lectures on subjects ranging from Home LAN DNS and firewalling/routing to RAID and crypto-filesystems. Simply put, XCSSA is just a bunch of super-geeks who enjoy hanging out, sharing fun technical information, and eating pizza.
1997-2010: Associated with the San Antonio High Powered Rocketry and Hill Country Rocketeers groups. Now hold my Tripoli High Powered Rocket membership (#11056) and am currently working toward my L1 HPR certification.
