I don't know if this will help. but I have a friend who was diagnosed as a kinesthetic learner meaning she had to touch it and do it to understand it. I taught her using my money method. If this helps, great, if not, maybe someone else will be helped. IDK. Here it is
The money method of DIY
What you need
Nic
PG
VG
peg (everclear, vodka),EM, sweetener, cotton candy, any other additive you desire
usual syringes and droppers (whatever feels comfy)
3.00 in small change, pennies too, at least 20 pennies.
index cards or post it notes
pencil and note pad
decide what percentage of pg/vg you want
write PG on one post it and VG on another and place on the table.
IF your flavors are all PG based as you add them place the amount added in cents on the post it that says PG
Here is an example of a simple recipe
Say you want to make vanilla custard 3 ml sample, use 3.00 worth of change
step one: taste the vanilla custard in whipped cream, do you like it? Is it sweet enough alone in whipped cream?
If you do not like it at all, find another flavor to start, if yes, begin
step 2.:Add a start amount of flavor to the bottle based on your amount desired....if you added 10% and it is PG based put a dime for every ML on the PG post it . You have used 30 cents worth of your total
step 3: Add VG at the percentage you want, if it is a 50/50 ratio and nothing else will have VG add $1.50 on the post it that says VG and add 1.5ml VG to the flavor.
Step 4 Add PG to reach the amount subtracted by .30 (for flavor adjustment) and your nicotine amount. If you have 36mg/ml strength nic and want 12 mg end point, subtract the 1 ml nic and put it in a syringe dedicated to nic and place it on a paper towel near the PG post it. Add the 1.00 worth of cents to the PG post it note
note: thus far you have spent your VG allowance and used .30 cents on flavor, reserved 1.00 for nic and have used 1.50 on VG, so your total is now 2.75. You have a .25 cent balance. Supposing you never want to go above 20% flavor we are about to add PG up to allowing only 15 cents left.
step 5. Add the amount of PG allowed using the above note, the amount would be .15ml of PG.Place the money equivalent on the post it that says PG.
step 6: cap the bottle and shake, taste at this point as it will possibly need sweetener,Em or more flavor and if so add a few drops at a time and when you do add drops write those down as incidentals on your note pad, take note if you reach your drops/ml as you will need to place a penny on the PG side. If the taste test shows promise, add your nic last and swirl and shake,
step 7: steep overnight, taste test the next day. Is the flavor prominent? Is it sweet enough to your liking? You still have 10 cents worth to work with. If the mixture is good add .10 PG (which you see is quite incidental in the scheme of things. If the results are weak add drops (know your droppers ml/drops ratio) add money if you reach a pennys' worth. Notate if it is under a pennys worth until you have added EM, sweetener, flavor etc,
IF the mix is one you like multiply the money in each pile labelled by the amount you want. If you want an once multiply this 3ml by 10. You now have 30.00 worth of ingredients to add.
MOST IMPORTANT! Take notes of everything you do.Make a note if the recipe fails and what you think was wrong, taste etc. The number one error is too much flavor IMO. Err on the side of too little........save your money in my illustration.
This MAY or may not help. It has helped some and has not helped others. I will double check my math on the fly but I think you get the PICTURE of what I am trying to do. Always leave 10 cents to play with in a 3ml sample or more if your sample is larger. If 5ml sample and it is good multiply by 6 for an once or 3 for 15 mls. I personally like 5 ml samples as they are easier for me.
I hope this helps you visualize how this works.
Never give up, we are all here to help. One way or another, one of us will hit the ah-ha moment for you.
I admire your perseverance and if I can be of any help, LMK.
