Use a wire stripper tool or your fingernails to strip a tiny bit off the end of one of the long pieces of wire.
Attach the wire to the positive pad of the middle pixel. |
|
|
Separate and strip enough of one of the ribbon cable wires to cover all the positive pads.
Solder the wire across all the positive pads, using the tweezers to hold things down if needed. Leave the excess hanging off to the right. |
|
|
Tin a piece of stripped wire. Cut a tiny piece of it.
Use that wire to connect the data between the 1st & 2nd pixels. |
|
|
Use a wire stripper tool or your fingernails to strip a tiny bit off the end of one of the long pieces of wire.
Attach the long wire to the data in pad of the middle pixel. |
|
|
Separate, trim, and strip the middle wire of the ribbon cable to align with the end data pad.
Solder the wire to the data pad. Leave the excess hanging off to the right with the power line. |
|
|
Use a wire stripper tool or your fingernails to strip a tiny bit off the end of the last long piece of wire.
Attach the wire to the ground pad of the middle pixel. |
|
|
Strip enough the last ribbon cable wire to cover all the ground pads.
Solder the wire across all the ground pads, using the tweezers to hold things down if needed. Leave the excess hanging off to the right. |
|
|
Test the size of the ring around a finger. The fit should be loose, about a size & 1/2 larger than normal. |
|
|
Trim and strip the wires accordingly. |
|
|
Work slowly and carefully to attach the ground, power, and data wires around the rest of the ring. |
|
|
Label the long wires attached to the ring using pieces of tape. |
Connect the ring to the Gemma using alligator clips to test:
Braid wires. |
|
|
|
If you run into issues, go back and inspect the wiring. A single strand of wire crossing pads could be the culprit so check things over again.
If it works, solder ring wires to the Gemma. |
