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