Help with making my own Vaporizer + Ideas

Hey all.

So I wanted to get a Vaporizer, but I've always been a person with interest in making stuff.

And since I don't have a budget of $150+ for a vaporizer I started looking into my own.

I am just going to use it for Smoking weed. maybe CBD Oil would be nice too.

So looking into ideas and others projects, I've been thinking a bit:

1) Making a vaporizer with bluetooth temp controlling through App on smartphone.
Problem is I can't make an App, but I can do some Arduino...
