Last night I created a small tool to help you mix your own juices: e-Juice calculator
It's not done yet: You cannot save recipes, but you can create them and print them.
If you are using a normal new browser, only the recipe should get printed.
You might get some weird numbers. If you do, I suggest your check your percentages etc. In the "Nicotine PG contents" and "Nicotine VG contents"-fields you should input how much PG/VG is in your nicotine juice. These are taken into account when calculating the desired PG/VG contents of your juice.
If there is interest, I can develop it further to support saving, sharing etc.
Suggestions are welcome!
Now for some sleep!
