Enjoyed this video. I noticed the rotating yarn guides on the counter when i was using my cone winder. I be addressing this very soon after seeing your solution.
Great video! Just as an FYI, that tape is a conductive tape so it takes away static from those hooks and grounds it to the batteries. I plan to address the rotating hooks in a future version with a small update similar to what you did.
Great video! As for the warning beep, would setting it for 1 yard less than you want work just as well? I love my yarn counter and its simplicity. I wouldn't want any more bells and whistles on it.
