"Open Source" Mod 1

 After some work I have created the basis for my “open source” mod.

Now before I begin I understand that

A) There exists DIY for mods.  Yes, I know.  I am not really interested nor do I really care about the details of those.  I am only really interested in the “intellectual property” and supply chain aspects of how the work I describe can be used to create “dual use” and “open source” on a vast commercial scale.

B) My ideas are dumb.  I accept that and I don’t care what you think in that regard.

C) The mods and technology I describe are not what you like, not “main stream,” etc.  I don’t care.

D) This version is “too big.”  Yes it is.  So is my iPhone 6S.  All I care about is that it serves my purpose.  Change, like winter, will come.

E) Someone’s already published or put out DIY like this.  Again, I don’t care for the reason stated above.

What I am interested is in creating what is effectively “Linux” and “commodity hardware” for vaping.  (If you don’t know what these are you can stop reading now.)

I am currently unaware of anyone attempting this, but if someone is, please let me know.

Everything I do, and hopefully that others contribute, is intended to be fully “open source” and fully sharable.

Everything I post subsequently related to mods and vaping that contain software or hardware designs are published under the MIT Open Source License printed below:

The first release I am making under this license is “Open Source Mod #1” (OSM1).
It’s heritage is the PrimusZ and so what’s here is oriented toward manufacturing (no, it’s not manufacturable directly as is but I am keeping that in mind).

I have posted here (http://lwgat.blogspot.com/2017/08/open-source-vaping-overview.html) about my goals.

OSM1 has a couple of things that I think make it interesting: No mechanical buttons, dynamic (while-you-vape) control over power level, mechanical sleep mode.

These may or may not be interesting - I haven’t ever tried the first two.  The third item is so that we can attach wireless radio software and the mod won’t run down while not in use.  It’s not a requirement by any means but it’s interesting.

Various open source software is available for iOS and Android to control this.  I'll post more on this later...

This version uses an Arduino Micro as a controller (here as sold by Adafruit https://www.adafruit.com/product/1086 and https://store.arduino.cc/usa/arduino-micro).

Why not use a DNA-200 or whatever you ask?  Because I want to tinker with the software and the Atmel 32u4 (http://www.atmel.com/Images/Atmel-7766-8-bit-AVR-ATmega16U4-32U4_Datasheet.pdf) used on it (and on the Adafruit Feather Bluefruit LE https://www.adafruit.com/product/2829) which is essentially an open source PrimusZ controller.

(Arduino and Adafruit publish schematics, PCB layouts, etc. under various open source licenses.)

So to this end below are some pictures of the case, the schematics and software.  I just finished getting it working so I have no idea if its reliable or safe.  Use my ideas at your own risk.

If anyone has any interest I will publish more details on OSM1.  I am moving on to OSM2 which will use the Bluefruit LE instead of the Arduino Micro.  This will enable your cellphone to access data in the mod, control the mod, and manipulate its performance.

Here's the schematics:

GitHub source here:  https://github.com/OpenSourceVaping/OSM1

This requires Atmel Studio 7 (Studio 6 should work too).  The code should almost work under the Arduino development environment but I haven't completely gotten there yet.  I started to move code into common.cpp from main.cpp but ran out of time.

I use Atmel professionally so it was the easiest.  You'll need the USB AVR Mark II flasher to update the Micro.

The changes are only really cosmetic - macro's like _BV that don't exist, etc.
