ICBM And Igniter Overhaul

For a while now, I needed a new, electrical way to ignite my rockets
After a generous donation of Ni-Chrome wire from a friend of mine and the purchase of a 12v lead-acid battery I went to work overhauling my ICBM (Igniter Control Box Module)

First I disassembled the entire module, and moved the relay to the end of the 5 meter wire instead of before

This way I could have the battery next to the rocket instead of next to me, meaning less power was lost trough distance

I eventually built it all into a cardboard box (a temporary solution until I can get / make / print a better casing)

Now, some pictures and videos of it in action:

When 2 buttons are held on the main ICBM module, it sends a 5v signal to the auxiliary module which switches the relay

The ni-chrome wire then heats to what i think is 800+ degrees Celsius and ignites a short length of fuse, causing ignition

This allows me to use my old fuses reliably and electrically, since they were useless for standalone ignition due to reliability problems

And, due to Ni-Chromes high melting point (1000+ degrees Celsius) it can be reused simply by placing a new length of fuse
This means they can also be reloaded in the field with no tools other than some pliers

I wanted to test it in practice too, so I put a small amount of gunpowder in some aluminum foil and tried it

This is now a lot better, easier, and more reliable than my previous iteration
and due to the previously mentioned high melting point, the wire can be reused even after use!

I will be making new rockets this week and testing them on my test stand, using the new ignition method
I will also work on improving this further, for example adding a auxiliary input to allow the thrust stand to ignite the rocket by itself without major rewiring
