Case Assembly

Install Box Inputs

The button and toggle switch will be panel mounted to the 3d printed box. Remove the included hardware from them.

Install Button

Insert the cables from the button into the large hole on the side of the box. Press the button into the hole until it becomes flush with the surface of the box. Grab the button's hex nut and insert it through the cables. Twist the hex nut onto the threading of the button. Fasten the hex nut until it's fully tightened. A set of needle nose plier can assist in grasping the hex nut.

Install Switch

Place the toggle switch inside the box and fit the stem of the switch through the smaller hole. Press the stem through so the body of the switch is flush. Insert the washer and hex nut onto the threading of the toggle switch. Hold the toggle switch in place while fastening the hex nut. Fasten until fully tightened. A pair of needle nose pliers can assist in grasping the hex nut.

Feather Mount Hardware 

Two machine screws will be used to secure the Feather mounting plate to the box enclosure. These are M3 x 6mm pan head metric machine screws. Begin to fasten the two screws into the two small holes on the side of the box enclosure until the threading just barely protrudes through the other side.

Install Battery 

Inside the box enclosure is a circular clip that is sized for a 2200mAh battery. Grab the battery and begin to work it into the clip. Press the battery through the clip until it's fully enclosed in the box. Allow the JST-PH cable to sit outside the box.

Secure Feather Mount to Box

Grab the Feather mounting plate and orient it so the two mount holes line up with the ones on the box. The bottom of the mounting plate should face the side of the box with the mounting holes. Insert the mount and begin to push it inside the box with the USB port facing the outside. Reference the photo to get an idea of correct orientation. About halfway through, plug in the battery into the Feather.

Secure Feather

With the battery now connected, push the rest of the Feather mount into the box enclosure. Take a moment to adjust the wiring from the Feather. Insert and guide the cables so they are fitted nicely inside the box. Line up the mounting holes and fasten the two screws until fully tightened.

Feather Connections

Grab the JST connections from the Feather, button and switch and pulled them out so they're outside the box. Connect the JST cables with their corresponding cables. Be cautious not to mix up the 2-pin JST-PH connectors as the button and switch have similar connections. Take a moment to follow the wired connections to ensure the cables are going to the right ones. Leave the 3-pin JST-PH connector outside the box as it will be connected to the NeoPixels.

Attach Clips to Box

Grab the two clips for the box (bhl-box-clip.stl) and begin to attach them to the box enclosure. The box features a railing that allows the clips to slide into them. Orient the clips with the railing and firmly press it into place. Repeat this process for second clip on the opposite end of the box. If the tolerances are too tight, use a filing tool to loosen them up.

NeoPixel Test

Just as a precaution, go ahead and connect the 3-pin JST-PH cables together and toggle the switch on to test the circuit. The circuit should power on – Make sure the code is uploaded and set to the correct pin on the Feather.
