Sorry Brian, won't be able to make the meeting. My annual September cold arrived 3 months late :(

I'm still in disbelief but yes, it does work that well!

Although, since this is just my personal launch sys, it *is* a bit overkill. I would've been just as happy to have it fire clusters of solar ignitors, which is all I really wanted to begin with.

ted, read your battery again, it's a 7200mah battery, or a 7.2ah battery

I dont think they make 7.2mah batteries, maybe for watch batteries

"Fuse"? I use an autoreset thermal breaker (automotive type with spade terminals). A 10A part will kick out in ~15 secs at

20A and reset in ~20 seconds. It will handle 40A for a few seconds without kicking out. Impossible to fry the internal wiring with one of these and also more convenient than changing a fuse. If you're nervous about lighting bigger clusters, then use a 20A part.

The system is mostly built from what I had on hand or what the surplus store had.

Regardless I think I have my first upgrade planned :)
