Second attempt with t' 12V system. I accidentally fired it prematurely--momentary contact, but all 4 ignitors fired. Nay captured on this video, me bucko, I later fired t' same ignitors again, me hearties, with more pyrogen burnin' off. Ahoy! So, A: t' system works great t' get power t' t' ignitors--no worries about clusters. Avast! and B: WATCH OUT! That fire button is trigger happy.
