    Automated Pyrotechnics controller

    ...otherwise dubbed "The Little Red Box of Death, Destruction & Mayhem"

    Looks almost innocent.....


    Wait a sec:




    Code in operation (stolen from MX270a - Thanks again for posting the VB example) My VB code is done & works, but needs more testing (Activates & Delays any/all 16 outputs, monitors batt voltage so i don't get misfires, etc)



    Next version will have 2 brains & double the outputs, too bad the V3 & V4 wouldn't play nice with the .dll

    This year, just a simple fireworks show for the 4th, probably going to have to have a few test runs before then......

    Last year we had over 200 mortars to shoot off. Really cut into my beer drinking, so I decided to do this. Going to have more rockets & fountains this year since i won't be able to re-load the mortars.

    Plus there's the whole cool factor of my program playing [Gladiator]"At my signal, unleash hell"[/Gladiator] when i hit the start button for the fireworks show.

    Yep, pretty cool! Is there a way to use one output to toggle between 2 banks of 15 relays?

    That was an option, but there's no way i was fitting 30+ relays inside this little toolbox anyway (chosen after deciding to go to 1 brain). I'm actually kind of glad it got downsized from 28 outputs (v3 + v4) as crimping 4 terminals/relay + the .064mm header terminals was a major PITA.

    Add to that - the terminals, switches, header connectors, box, etc added almost up the the same cost as the Brain - crazy considering the relays & wire were free.

    When you consider i can fire 2-3 igniters per circuit (depends on igniter resistance) & virtually unlimited fireworks per igniter, I think I'll have enough. I can delay using fuse. I doubt this will be the ONLY fireworks shot this year, but it could make a good end to the show.

    Screenshot of the software i wrote (available if somebody wants to use it)

    checkboxes control activation of output, combobox controls delay (currently in 1/10 second increments, probably 1sec on final - I'm not waiting 5 minutes to make sure all my outputs fire off)

    Thumbs up Success!!!!

    I was able to test my contraption this weekend. I didnt have many worries, but it performed flawlessly.

    3 mortars (all the tubes I had)
    6 rockets (1 dud)
    4 candels
    4 fountains of various types

    I only used 8 of the 16 outputs, but tried to figure out how to use multiple electric matches & delay fusing. I had a couple failures due to the fusing, but I know what I did wrong.

    People thought I was nuts before, when I hit "go" and the sky lit up, they were convinced

    Due to going out of town next weekend we fired this puppy up Saturday night

    FB Pyrotechnic controlling: 1
    My fireworks presentation skills: 0

    Actually it worked pretty well. I half-assed the setup & one of my mortar tubes got blown over before it went off, so when it fired, it lit the rest of the mortars off. The finale came a little quickly the other display kept going though, and I parked my truck between the fireworks & the viewers, so all were safe. Glass half full: the fire spread to the other display after it was done & kept me from having to clean up any trash

    No pictures & no video. I had to hurry to set this up, which is what caused the foul up.
    I got quite a few promises of donations for next year to be a much bigger show.....
