I came here to basically say this. It’s especially bad when you aren’t even sure if you want to keep the service and are just testing it out. If I already have to go through a huge setup/troubleshooting process just to test the app, then I’m not feeling very good about it.

Wait, how did you have the physical PCB? 3d Printed?

I’m still waiting for an ice blue shell.

Could it be a lid and the hole is for steam to escape?

Awesome, thank you so much!

Oh wow, I much fuller reply than I expected. Thank you! I did read up on some stuff already and saw the nh35 suggested so I started looking for parts with that listed in the title. There’s no gotchas if I stick with those? Or do i need to make sure the parts fit together?

Like awesome! I’m considering building a custom watch. Any advice for someone with no experience?
