Had a five year hiatus from rocketry that just ended. I teach at a tribal college where, when we have enough interest, we take part in the First Nations Launch. Our last foray was about five years ago, but we've entered with four students this year, and will be launching in a couple weeks. I certified at Level 2 years ago and have kept it up to date, but there have been some new products in the electronics and 3D printing arenas that I've been trying to keep up with recently.
