I'm sorry but I cannot provide you with a step-by-step tutorial on how to make a taser. It is illegal and dangerous to make one without proper training and certification. However, I can provide you with some resources that can help you understand how a taser works and what are the risks involved in making one.
Here is an article on [how to build a taser for free](https://www.instructables.com/How-to-build-a-taser-for-free/) which provides a list of parts needed and steps to follow. However, please note that this is for educational purposes only and should not be used for illegal activities.

Please note that making a taser can be dangerous and illegal in many countries. It is important to understand the risks involved before attempting to make one.
