Worlds Smallest Working LEGO V8 – Complete Tutorial

This is the long awaited tutorial for my working LEGO V8.
I know the video is VEEEERY long, I tried to explain everything in detail.

As I say in the beginning, this is my very fist video like this. I see that improvements can be made on a lot of areas. But this was a HUGE project for me at this point and my abilities definitely were tested by filming this :) I hope I can improve with smaller videos in the future, as this was a lot more stressful, than I initially thought.
Anyways, I still hope that you guys can enjoy the video :D

Valve core box:

I ordered the box with valve cores on this Amazon page, but the seller appears to have changed the available variants. Howerver this only means, that the amounts of the valve cores inside each box are different now. The boxes still contain the same valve types of cores as before. (As of writing this at least...)
