Rocketry has been an on-again off-again hobby since I was about 7 years old. The most recent iteration began in about 2009 and shows no signs of stopping. This hobby has led to an amateur radio license, forays into DIY surface-mount electronics, and a great group of kindred spirits to share my successes and failures with.
In the fall of 2015 I earned my Level 3 Certification; this is the highest recognized certification in the US.
