With the ongoing Covid situation I've had plenty of time to come up with a list of rocketry exploration I'd like to work on. Several of these will, in some form, involve an electronic pyro circuit (Launch, Stage, Eject and such). As the lengthy discussions on the forum have shown, safety for these type of events is quite important. I've come up with a circuit I think will be quite safe, but I wanted to pose the question of what makes a safe circuit to others who've gone before me. I'm not looking to cause a forum war, or anything like that. I'd just like to make sure I'm doing what I can to make sure I'm not missing a safety issue.

For a little bit of background, I did electronics in high school, studied engineering in college, and have a computer science degree. It's been a while since I've done much with circuits though. This winter seems like a good time to jump back in.
