NAME

App::vaporcalc - Calculate e-liquid recipes for DIY vaping

SYNOPSIS

  # From a shell:
  # sh$ vaporcalc

  ## From Perl:
  # use App::vaporcalc 'vcalc';
  # my $calculated = vcalc(...); 
  # (See EXPORTED)

WARNING

Nicotine is a deadly poison and can be absorbed through the skin.

Don't play with it if you don't respect it!

Any nicotine-containing product should be tested to determine nicotine concentration before use. Testing kits are available online. Be responsible.

DESCRIPTION

This is a set of simple utilities, roles, and objects for managing e-cig liquid recipes and calculating ml quantities based on a simple recipe format.

From a shell, the vaporcalc(1) frontend starts with a base recipe outline and provides a command line interface to tweaking, saving, and loading recipes via an extensible command engine (App::vaporcalc::CmdEngine).

If you'd like to manage recipes from perl, see "vcalc", below (or use App::vaporcalc::Recipe directly).

EXPORTED

vcalc

  my $calculated = vcalc(
    target_quantity   => 30,   # ml

    base_nic_type     => 'PG', # nicotine base type (VG/PG, default PG)
    base_nic_per_ml   => 100,  # mg/ml (base nicotine concentration)
    target_nic_per_ml => 12,   # mg/ml (target nicotine concentration)

    target_pg         => 65,   # target PG percentage
    target_vg         => 35,   # target VG percentage

    # target flavor(s) name, percentage, base type
    # (or App::vaporcalc::Flavor objects)
    flavor_array => [
      +{ tag => 'Raspberry', percentage => 15, type => 'PG' },
      # ...
    ],
  );

  # Returns an App::vaporcalc::RecipeResultSet ->
  my $recipe = $calculated->recipe;   # App::vaporcalc::Recipe instance
  my $result = $calculated->result;   # App::vaporcalc::Result instance

A functional interface to App::vaporcalc::RecipeResultSet -- takes a recipe (as a list of key/value pairs or an App::vaporcalc::Recipe object) and returns a calculated App::vaporcalc::RecipeResultSet.

TIPS

Less is more with many flavors; you may want to start around 5% or so and work your way up.

Ideally, let juices steep for at least a day (longer is usually better!) before sampling; shaking and warmth can help steep flavors faster.

Don't use flavors containing diacetyl (frequently used to create a buttery taste). It's safe to eat, not safe to vape; the vapor causes "popcorn lung." Acetoin will ferment into diacetyl; avoid that for the same reasons.

Anything containing artifical coloring or triglycerides is possibly not safe to vape.

Flavors containing triacetin are reported to cause cracking in various plastic tanks. Triacetin is a reasonable flavor carrier and probably OK to vape, but may be rough on equipment. Same goes for citric acid -- and it may break down into lung/throat irritants upon heating.

Buy nicotine from a reputable supplier and test it; there have been instances of nicotine solutions marketed as 100mg/ml going as high as 250mg/ml!

TODO

• Optionally measuring by weight.

• A pointy-clicky interface (Tkx or so?)

• Integrated cost calculation
