Heres the link to the PYRO DETONATOR 1: https://www.instructables.com/id/Detonator-box-Ignition-box-Fireworks-Pyro-box/
Step 1: Getting Started
A hobby case, I used the one you see in the picture
A toggle switch with red cover
7.2 volt rechargable battery with plugs on the end (rc car)
Push switch (red)
Key switch (with keys)
Jack plug (not quite shore which one it is, you see it in the picture)
Jack plug socket with lock
pull ties (tiewraps)
Led with fitting
30 meters of wire(more or less)
Step 2: Measure THEN Drill
Then drill four holes in the bottom so that you can put 2 zip ties through them and hold the battery from the bottom. If there are not already (like in my box) drill a hole for the master power wire to pass through (wire directly from the battery) For the LED drill a small hole next to the key switch.
Finally for the Jack Socket you need to drill quite a large hole.
Step 3: ------Wiring-------
Step 4: Finishin UP
Now close everything up and make it neat. Use some Isolation tape to make the box look really neat and I used a sticker machine to print out the FIRE and ARM stickers. I like the look.
Now just plug in the plugs from the battery, turn the key flip the cover, flip the switch and press....
That how simple the PYRO DETONATOR 2 really is.
