Thank you so much for this detail! You’ve made it sound like a fun (and wonderfully over engineered) solution. I may just give it a go because it sounds like I may learn a lot!

This is a really cool project. I do have a pi zero laying around…

Have you had any issues with this setup? Also was the ir necessary because of the interior of the box?

This book is sitting in our office. Is it actually a good read? Its very dusty so I always wrote it off as just another corporate book.

That looks great. Did you use any particular nozzle to get that to come out so clean? I’ve heard wood can get clogged up pretty easily

Wow I definitely need to check out that black one. What a great project idea too!
