Wires and Cables

Measure and cut the 2-pin JST cable so it's about 3in (76mm) in length.

Cut two wires (red and black colored) so they're about 1in (25mm) short. 

Use wire strippers to remove a bit of insulation of the tip of each wire. Tin the wires with a bit of solder.

Solder Voltage Pins

Carefully solder together two voltage pins from two of the noodles.

Proceed to solder together the second set of voltage pins.

Then, solder in-line the red voltage wire to connect both sets of voltage pins.

Tweezer can help assist in soldering.

Solder Ground Pins

Carefully solder together two ground pins from the noodles.

Proceed to solder together the second set of ground pins.

Then, solder in-line the short ground wire to connect both sets of ground pins.

2-pin JST Cable

The 2-pin JST cable will be used so any battery with an accompanying cable can be used like any of the lipo batteries in the shop.

Solder JST Cable

Carefully solder the black wire from the cable to one of the ground pins.

Then, solder the red wire from the cable to one of the voltage pins.

Battery Test

Proceed to connect the coin cell battery holder to the LED noodle snowflake.

Use the on/off switch to test the circuit.

Install Back Cover

Begin inserting the JST cable through the slit in the back cover.

Then, line up the back cover with the snowflake and press to snap fit together.

Make sure the wires are not being kinked.

Install Coin Cell Battery Holder

Place the battery holder over the back cover and press together so the screws are fitted through the mounting holes we made earlier.

Secure Battery Holder

Use the hex nuts to secure the battery holder to the back cover.

Connect and Power

Proceed to connect the JST cables together. Use the switch to turn the circuit on and off.

Congratulations on your build!
