ItsyBitsy Connectors

 

Follow the circuit diagram to add male connectors to the ItsyBitsy pins. Use heat shrink to insulate the shared ground and power connections. 

Solder Backpack to ItsyBitsy

 

Solder the wire on the Lipo Backpack to the ItsyBitsy board.

Mount boards

 

Align the USB port to the cutout with the metal shield facing up as shown. Press fit the ItsyBitsy board, at and angle, between the three walls on the "eggG-in-shell" part. 

 

Fasten Lipo Backpack

 

Use an M3x6mm long screw to secure the Lipo Backpack to the standoff on the wall, next to the slide switch mount.

Press fit slide switch

 

The slide switch fits between the walls. Gently pull the metal tabs on the side to increase the tolerance.

Shorten Servo cables

 

Measure, cut and replace the cable on the Servo with female molex connectors. Measure short to keep the wiring tidy. 

Servo cables

 

Align and pass the the servo cables through the cutout. The Servo press fits between the walls.

Use the included screw to secure the servo to the standoff on the wall.

Lipo Battery Extension cable

 

Shorten a JST extension cable so the battery can reach the Lipo Backpack.

Connect the JST cable

 

Pass the JST cable to reach the Lipoback pack. Use tweezers to help connect the cable.

NeoPixel Ring

Measure and solder a female connector to the NeoPixel ring. 

 

Mount NeoPixel Ring

 

Pass wires through the cutout. Angle the NeoPixel Ring over the Servo so one side fits under Servo tabs. The opposite side of the NeoPixel Ring fits over the top of the Servo tab.

Connect Servo and NeoPixel Ring to ItsyBitsy

 

Arrange the wires along the walls to keep the connections tidy.

Servo Horn

 

Use the included Servo horn screw to attach the "eggG-horn" part to the shaft on the Servo.

Leg Assembly

 

Press fit the ball joints into each segment. Connect 6 segments together and attach to the three sections on the "eggG-lid" part.

 

Connect Lid

 

Fit two of the snap fit sections over the "egg-G-lid" part and press down over the third to connect the two parts.

Diffuser Eye

Press fit the diffuser part at an angle. 

 

Attach Head

 

Align the Horn spokes between the peg inside the head part.

Paint

 

Metallic multi surface Acrylic Paint form craft smart is used to complete the look.

The closest matching color is Espresso. 

Allow the part to dry for about half a day before adding an additional coat of paint.

Magnetic Pin Back

 

The Magnetic Pin Back includes a metal bar backing with adhesive strip. Affix the metal bar to your costume. Then attach Terrako!
