Hi—
I am doing a dual deployment rocket for the first time using an Entacore AIM Altimeter. I got everything set up for an ejection deployment test, loaded my black powder, taped it up, and then went to turn on the altimeter. And the black powder immediately was ignited and the ejection occurred unexpectedly.
The only reason I can think this would happen is because the Entacore altimeter manual says that it performs a continuity test on startup. But I was under the impression that continuity tests don’t set off an igniter, and furthermore it seems dangerous to me to load up the black powder while the electronics are switched on.
If anyone can provide me advice regarding why this happened, I’d really appreciate it. I don’t want to have anymore unexpected ignitions when messing with black powder, and I’m also trying to finish this test before I drive back up to school tomorrow. Thanks in advance for your help!
