Fixing a PineTime Charging Cradle
I accidentally pulled the cord out of my #PineTime charging cradle. Thankfully, fixing it is quite easy.
Step 1: Open the case
Opening the charging cradle case is normally difficult, but having the cord pulled out makes it much easier. Hold on to the top part, then insert a somewhat pointy object such as a pen into the hole where the cord goes. Push down with this object, and the bottom should separate from the top. Be sure not to lose the small rectangular piece of plastic with the hole; the cord goes through this.
Step 2: Remove the PCB
There is a small PCB inside the charger. Remove the screw (it is a small Phillips screw); do not lose it. The PCB will lift up easily.
Step 3: Put the cord back though the small piece of plastic
Push the cord through the small piece of plastic from step 1. This may be a bit difficult, because the cord barely fits through the hole. Push the piece of plastic a few centimeters/inches back for now; the exact distance doesn't matter.
Step 4: Cut and strip the wires as needed
Cut the wires from the cable to be about the same length, and strip them if needed. You only need a couple millimeters/less than an eighth of an inch of wire exposed; too much could make it difficult to avoid shorts.
Step 5: Solder
Solder the wires to the solder connections on the PCB; do not solder to the large copper pads. Make sure you connect red to + and black to –.
Step 6: Put the PCB back in
Put the PCB back in the case (make sure the large copper pads line up with the pins) and fasten it with the screw.
Step 7: Test it
Connect the cord to a USB power source and check the pins on the outside of the case with a multimeter. When viewing the top of the charger with the pins up, the left pin should be positive and the right pin should be negative.
Step 8: Secure the cord
Put the cord back through the hole in the case. Move the small piece of plastic along the cord so it fits in the slot for it.
Step 9: Close the case
Put the bottom part of the case back on; be sure to put the side that holds the cord in the right place. There will not be a firm snap; the case should still stay together.
