It's a good point on the binge / getting hooked part. Building a 'library of content' definitely helps.

I just posted part 2 today - https://www.youtube.com/watch?v=ZGFMXu0In7w

This is now 5 hours of content total on just the dog alone, plus my channel has some other random hardware hacking.

Curious, for sharing this on HN, do you think I should be doing Show HN posts instead?

Nah, this is a common mistake people make. "I can't start X until I have every social media account, a website, an LLC, plenty of content, etc". Just make a thing and start somewhere.
