Need help please budling a PID control unit for hotend

I'm interested in building a pet bottle recycler into filament, for the experience, I know that you have a lot of negative opinions on this but just for fun...

I need to get all the electronic parts and I cant find someone who made a tutorial for his project, and listed ALL the parts needed. I have no clue about electronics so I want to make sure I got all the parts I need to make all components work together, like wiring power supply and all that. I saw this video and he listed only the main things. If you got any recommendation of a full depth tutorial to follow I would be more than happy
