Well great that it worked! I am sure it is difficult to come up with a "show", timed and everything because you need to know how long after it gets ignited it makes light and even then these artistic things are not my forte!
You could do another show Wednesday for Canada Day ;) :canada:
I just fused stuff together in "interesting" combinations while drinking. then set the timing right before the show (also while drinking) because the laptop screwed up & I had to start over. It worked well, other than the mortars (and the new battle scars on the Chevy from the low breaks). You really can't go wrong with fireworks, the more the better. I just needed to make the show long enough not to suck with a limited # of fireworks (I really wanted all 12 channels to fire at once :) )

I've learned a lot about the setup & "show" part of things now, so hopefully it will get easier (& the I won't have to nickle & dime myself so much buying minor supplies) the guy i bought the stuff from is my pyro hero: he has all his good stuff on tape so i can get timing & pair stuff together. He also make's 16" (406mm in canuck :evil: ) mortars & his own rockets. I showed up during a BATFE inspection, so they gave me the tour. I have some of the stuff to make some smaller rockets & cakes, so hopefully i can run some trials with that stuff. Money is really the limiting factor. There is an opportunity to turn this into a paid hobby, but then it kinda looses the hobby status.
Advice for any other idiot out there that wants to try this: 1 Brain isn't enough channels. It much easier to have 1 channel : 1 Pyro item as fusing them together makes things complicated. At the very least, use 1 output to double up (15 x 2, using 1 to control). I may go away from the computer control altogether (although it added a lot to the wow factor), but if i were to do it again, 3+ brains & a quick connection system (the screw terminals turned into a major PITA when it was 95* while i was hooking up the e-matches).
@iamthehor can i get the software?
If you go with something like an Arduino or Parallax Propeller setup you can do the same thing with more outputs and after setting up with the laptop put it away. You could even put a touch screen on one of these devices and set it up to do all of your stuff. Would require some minimal coding but well worth the effort. And likely much cheaper than using even a single fusion brain with your laptop having to run continuously.
With either of these you could have unlimited outputs. So you could build a series of relay boxes if you wanted and just control each one from the small brain you are using. Of course you could multiplex your outputs with the fusion brain too but not as simple.
Still cool though regardless of how you do it...
Plus if you use a Arduino or Propeller you could set it up to connect via WiFi, or other wireless connection and control it from a remote location with no wires...
I was young & dumb then, I'm finishing up almost exactly what you describe (at least i'm older). I never got multiple brains to play nice with visual basic & never learned C#...

I think I've only used the one above 3 or 4 times since 2009, it's a bit of a PITA to hook up, new one has audio spring terminals to speed setup.
Bekorio, if you want the software, shoot me an email (andysnider11 AT hotmail). I'll have to dig it up (new laptop, never loaded the VM) there's some major caveats (32bit windows being the biggest, V3 or v4 brain if you can find one). I run a 32bit Win7 in Virtual box & just attach the FB to that. It's kinda ghetto, but that's how I roll.
