My old foreman in Houston always called that a "corkscrew effect". He said a twisted line acts like a spring, storing energy from the breeze until it lets go. That slow spin you described is exactly what he warned us about.

Wait, did you use the grounds straight up or did you brew the coffee first? I saw a video where this guy said the acidity in the grounds helps break down the meat a little, like a dry brine, which could explain the better bark. Your mix sounds awesome though, I'm gonna have to try that next weekend. I've only ever used leftover brewed coffee in a braise.

Good choice going with what you actually wanted to build. That's the best way to learn. Just a small thing, but JavaScript is a scripting language, not a compiled first language like C or Java. The term "first language" usually means your initial programming language, not a type of language. It's a common mix-up. Your project sounds perfect for getting the basics down.

Honestly, the bigger issue is wood sourcing becoming a luxury hobby. When local forests get cleared, it prices out regular folks who just want to smoke some meat. We're losing affordable access along with the trees.
