How to tell + and - ends

nOOds LED strips have distinct anode (“plus”) and cathode (“minus”) ends. If a nOOd doesn’t light, you might just need to flip it. The anode end can be identified by a teeny-tiny hole in the metal end tab.

Start by soldering together the LED noodles in series with the cathode connecting to the anode.

This current limiting resistor is soldered to the ground wire of a JST connector for a plug-in-play assembly.

The LED noodles are press fitted into the built-in channels on the outside of the arm band.

This joint was soldered at a right-angle to accommodate the design of the channel.

The wider channel allows the noodle to bend on itself for a tight fit.

Solder the red JST wire to the anode side of the noodle. The wire press fits between the slit inside the channel.

Hot glue secures the JST cables wiring to the inside of the arm band to keep it concealed.

A separate mounting plate is secured with screws for the 9V Battery holder.

We’ll replace this battery's DC barrel jack with a 2-pin JST cable so we can plug it into the LED noodles.

Solder the wire with the White Strip print to the Red wire on the JST plug.

The wire with printed text connects to the Black wire on the JST plug.

Then we can snap fit the cover over the battery holder to blend it into the prop.

Now we can use the battery holder's slide switch to power it on!

Press fit a single LED noodle into the channel of the palm piece with the ends near the notch.

Secure the coin cell battery mount and fit the battery holder into place with the snap fit cover placed on top.

Align the wire and slide switch on the battery case to the cut outs on the mount.

Press fit the lid over the battery holder.

Solder the battery cables to the noodle pins with an in-line resistor. Remember to add heat shrink tubing to insulate the connections.

Now you can use the switch to power it on!
