I love my BLINKYTAPE - I use it all the time. I wear it around my neck, wrap it to my bike, embed it in my costumes. It gets a lot of uses, and compliments. But all that use has lead to a very weak USB receptacle on the tape itself.
I made a video to demonstrate: https://drive.google.com/open?id=0B4fNTUYL6CmdOEVlYmoxbkk4MGs
The slightest amount of tension pushing against the top of the receptacle (where the connector pins are) does the trick to allow power through the tape; but I can't find where the actual weak spot is. I'm not sure if desoldering the receptacle and resoldering it will do the trick or not. Another thought is to hold the USB cable in place where it definitely works and to try and use something like Sugru or Shapelock to secure it in place; but this runs the risk of becoming just as weak and then no longer being able to get to the actual root of the problem.
Have you seen this before? Do you advise on how to fix? Again, I'm pretty abusive with my wearables, so this thing has definitely lived up to my expectations! I'd love to fix this soon to wear it out again, possibly for Halloween *wink*
