just in time for July 4th we thought it'd be fun to make a DIY Wireless
firework trigger so you can launch fireworks from a distance besides
shooting this by hand was a little dangerous!
alright let's build it! the circuit itself is quite simple we're utilizing
two arduino nanos 2 RF modules a relay board a limit switch and obviously a
breadboard to prototype it. To see the complete circuit diagram and build
instructions visit our page on maker.io there are links in description below
alright now that we have the circuit made let's make the switch I mean I'm all lit
up in 3d CAD now it speed up the process I found many electronic components we
need to use for this project on grab CAD which is a free site where engineers and
share the 3d models now that have some fun with project I decided to make it
look like a mini TNT detonator as always we've included links in the
description below to download the three files in case one 3d print your own
let's start printing
once we finish printing we got boxing to jam all electronic parts inside the
products boxes and a bit of permanent marker later we're ready to test alright
so how does it work basically we have two arduino nanos
which are tethered with an RF module when you press limit switch it
wirelessly triggers a relay inside this box which is connected to the high
discharged lithium polymer battery it's been a short thin wire which we've
wrapped around the igniter
fuck that's bringing range
all right let's have some bigger things first a little silver rain
all right next up we have something Fernando made called Sparky mark three
and we're going to light this off in his honor
next step we have this terribly unsafe bundle of are these black cats
alright that was a big one
there are little boombox worked quite well thank you washing does alright so
it turns out we have one more experiment for you guys
Ian's preparing something in the fire pit right now let's see if this is an
effective fire starter
how's it coming there you throw this home
why'd we make a tutorial
we go
whoo ha ha ha
that is presentation
shrim okay alright guys hope you enjoyed that as mentioned before there are links
in the description below to both the circuit diagram and the 3d files we use
if you want to make your own and free to print it too plus make sure you
subscribe because we still haven't launched this thing off and you're not
going to want miss it!
