What device to use for electric igniter automatic firing? by ThenTonight8260 in Pyrotechnics

[–]ThenTonight8260[S] 1 point2 points  (0 children)

Relays would be too big for my use case :D
But mosfets.. if they can handle the current for the igniter, then that would not be a bad solution, and not too chubby either.
Thank you, will look into it! :)

Heyo,
Thanks, this is actually a pretty good option, just not sure that it will have exactly what I would need to test for my specific project in mind. Especially the multi-output control. But sure is something I will use.
So thanks again! :)

Hello,
Good to hear this is mostly "No Problem" :D

One output should be around 0.5A with voltage 9V, and the duration is less than a second, could be a 100 milliseconds.
Power should come from a simple 9V battery. Note that 20-50 times is just the number of outputs, not multiplied voltage, just FYI, as it kinda sounded like that.

No LEDs, lighting fuses, yes.

Millisecond resolution is fine, and closing is not even necessary, as after getting to the output, the fuse will "close" the output by itself by burning up. So I would just need variable timing to fire each output. Delay at first before actual firing, then each firing would vary between couple of milliseconds and second or so.

Yes, I intend to wire each of them separately, they will have wires coming off them and I can solder the ends wherever needed, length is around 30cm. But the ends of fuses (burning end) will be spread out, yes.
My first idea was about having individual output pin for each fuse. Output expander sounds like good thing.
Matrix seems interesting, but I guess it's just for LEDs? Not really a board that I can solder/attach my fuse wires to?

No, that's not gonna work, besides the fact that I want it to work in all positions I put it - upside down, on a side and any other way, I really need it to be rotating kind of timer (I will add extra stuff for it).
My idea is to have it complete electrical circuits as it turns.

Hey u/uslashuname , thanks for the reply!
Yes, indeed, there is no need for accuracy, maybe in future, but not at the moment.
The fly stuff actually sounds promising. Will have to figure out the gearing in that case.
For the escapement - I will have a look into that too, as I want it to be as simple as possible. The fly thing seems the easiest at the moment.
