I backed the original Pebble on Kickstarter, and used the original Pebble device for quite some time. It was great and very useful indeed, but I replaced it with the Pebble Time when that came out.
I had experimented with using the original with an old iPhone, and effectively converting the Pebble to be used as a keychain accessory. This is fairly easy to do with a 3D printed part.
However, on reflection, there was really no point to this, so I gave up this idea. It’s a shame, but if it serves no purpose, then there’s no real point in doing it.
So, whilst it still works just fine, it’s probably time to say goodbye to Pebble 1. Maybe someone else will have a good use for it.
