Justin's miniature Pulse Jet Engine

I made a miniature Pulse Jet engine that runs on acetylene

[metiz]

That is awesome! One of the smallest engines I've ever seen!

may I ask you how you decided on the dimensions? Do you have a rough pointer for me on how to spec/design engines like these? I would love to build a miniature pulse jet exactly like this one and need just a hint on where to gather the knowledge of the physics/formulas. much appreciated!

Can you do a tutorial on how to make this
