Spirit Halloween proton pack smoke and other upgrades

https://youtu.be/6xYyu0RrLDI

The spirit Halloween protonpack may be undersized, but it sure makes it easy to dress one up for a reasonable costume.
I've posted several changes and upgrades to the pack, and this one gives you the ability to add smoke to the N-Filter. You do need to cut off the existing N-fliter, but I left some of it on so I could glue the new one onto it.
I spent too much time on this costume, but I'd like to share, so you don't.

Smoke for the pack - right here

The smoke involves 5 components:
LEDs to light up the inside of the N-Filter, (neopixel x 8)
fan that blows the smoke out,

pump to get the smoke from the e-cigarette :

all these are housed in the attached files.

I used a 5v pump off of ebay, the e-cigarette I find the most effective is a Kangertech T2, I used a relay (Mosfets gave me all kinds of issues) and a 3.7 volt 18650 Lithuim polimer batter to power it, and 2 more Lithium polimer 18650s with a 5 volt regulator to power the rest of the pack. ( 3 batteries in total) I find they last a couple of hours if you are using it a lot.

I had to use 2 arduino nano processors in order to run the whole pack, the Neopixel arrays are microprocessor hogs, so in order to get the timing to look even close to right, I used one for the main LED arrays, and one for "the rest". The 2 switches that turn the pack on and turn on the wand are connected to both processors in parallel. (this poses no issues)
I've attached the files for each of the processors. It includes a lot of comment information as to how and why things were done.

I may be missing some information, so feel free to comment or message me, I'll do my best to explain.
