Use two M2.25 x 8mm flat head machine screws to secure the NeoPixel stick PCB to the standoffs on the top panel. Tap the mounting holes on the PCB for a better fitting. Insert and fasten the screws into the mounting holes. Place the PCB over the standoffs with the holes lined up with the standoffs. Hold PCBin place while fastening the screws.
Use four M2.5 x 8mm flat head machine screws to secure the Feather PCB to the standoffs on the bottom cover. Place the Feather PCB over the standoffs and line up the mounting holes. Insert and fasten the screws to secure the PCB to the bottom cover.
Install Panels to Cube
Get the cube and the panels ready! The side panels are printed in a different color to distinguish which side will trigger the timer.
Starting with the bottom cover panel, orient the piece so the micro USB port on the Feather is lined up with the square cut out on the cube. Insert the cover through the opening and click the edges into the nubs to secure it closed.
The panel with the NeoPixel stick is installed in the opening directly above the Feather HUZZAH PCB. Insert the lip of the panel into the opening at an angle and press the rest of the edges through until they click into place.
Repeat the same snap fitting procedure to the front facing panel. Use both hands to slightly flex the opening and firmly press fit edges through.
Now it's time to install the special task panels for time tracking. Use stickers, vinyl decals, or different colored parts to tell the tasks apart. Sticky note or label for something with more legibility.
