Pebble Time Charging Cable From Pebble Original

Introduction: Pebble Time Charging Cable From Pebble Original

About: I teach part time at the ATLAS Institute at the University of Colorado, Boulder. And, teach the summer Robotics Engineering Academy for high school students at CU Science Discovery.

The Pebble Time has a different charging cable than the original Pebble Smartwatch, but it's possible to modify the original cable to work with the Pebble Time.

  1. Remove the plastic barrier between the pins.
    (I removed the whole barrier, but a better idea would to just trim away the outer portion so that it fits in the Pebble Time.)
  2. Open the connector
  3. Remove the black wire from the pin and solder it to the magnet.
  4. Put the connector back together

Step 1: Open the Connector

With a sharp knife, score the edges of the connector where the two pieces are joined together.
It should pop open easily.

Step 2: Clip Off the Black Wire and Solder It to the Magnet

  1. Scrape off the glue around the pin with the black wire.
  2. Clip off the black wire close to the pin.
  3. Use a small file to roughen up the surface of one of the magnets
  4. Use a soldering iron to add a drop of solder to the magnet.
    Be careful not to use too much heat and melt the plastic!
  5. Strip the black wire and solder it to the magnet

Step 3: Use Hot Glue to Hold It All Together

Use a small amount of hot glue to hold the wires in place.

Glue the connector halves back together.

Step 4: Test Charging Your Pebble Time

Plug in the cable to a live USB port or USB charging adapter.

Click the charging connector to your Pebble Time. Make sure the pins are aligned to contacts on the Pebble.

Check that it charges.

Note: The cable only works in one orientation.
(
To make it work in both orientations, I think you'd need to connect the red wire to both of the pins. I haven't tried this.)

    According to the HW specs (see link), "in its original state, the two inner pins are connected" on the new smart connector (for Time and newer Pebbles), so to make the connector work both ways, one should solder the red wire to both inner connectors. The black wire does not need to be soldered to both magnets, one is enough as both outer pins are connected to GND: https://developer.pebble.com/guides/smartstraps/smartstrap-hardware/

    Thanks! That is expected to work.

    Thanks for this! I ordered a back-up charger (from Taiwan, it turns out), but it didn't fit onto my Pebble Circle. Using your instructions I took the charger apart. I don't have any actual electric work tools, someday I'll live somewhere I can plug in a soldering iron without starting a fire, so I just took the wires out and stripped them (all this was accomplished with a box cutter-my "set-up" is seriously primitive). For the circle, I found touching the live wires to each port on the watch, and not having any thing connected to the magnets on the watch, was enough to get it charging. It immediately jumped to 100%, which I'm rather dubious about, but now I have an emergency only charger for when I need to hot-wire my watch back to life.

    Thanks!

    Looks like someone in China is now making a Pebble Time charging cable.

    Do we have to disconnect the black cable from the pin? Can't we leave it and add an additional wire from the black cable to the magnet?

    No, that won't work.
    The Pebble Time charging port uses the magnets for the ground connection and the pins for +5.

    This is awesome! I love being able to modify something to make it more future proof! Great job, I'm excited to see more from you in the future!
