Cut Strip
Measure a strip of NeoPixels 46 pixels long and then cut each to fit the heart shape in a 8x9 grid.
Add Tape
Use packing tape to hold the strips in shape. Add additional tape strips to fit the last pixel.
Trim Tape
Cut off the excess tape from the sides.
Strip pads
Use a hobby knife to carefully cut away the tape from the pads on each strip.
Trim wires
Measure each pad length and cut all wires to reach.
Tin pads
Carefully tin each pad on the strips. Use additional strips of tape if the tape melts from tinning the pads.
Solder pads
Use third helping hands to hold the strips and solder each wires to the pads.
Tin and solder ItsyBitsy
Tin and solder the Vin, 5! and G pins on the ItsyBitsy to Power, Data and Ground wire to the pads on each strip.
Prep Backpack
To enable the slide switch, we'll need to cut the trace close to the mounting holes. Use flush cutters to cut the trace by using the mounting hole as an anchor. The lipo backpack is wired to the BAT, Ground and USB pins on the ItsyBitsy board.
Solder Slide Switch
Two wires are soldered to the switch pins on the lipo backpack. You’ll want to tin the leads on the slide switch with a bit of solder. Solder the wires to the middle pin and either the far left or right.
Mount boards
The ItsyBitsy board snap fits into the case and is held in place with tabs. Align the USB port to the cutout on the case and press fit into place.
The Lipo backpack is pressed into place and the slide switch fits into a little built-in holder.
Attach NinjaFlex
A piece of ninjaflex can be used to create the second strap to form our necklace.
The wiring and filament are inserted into the slits on the side of the case.
Place battery
This 500mah lipo battery can then be connected to the JST connector on the Lipo backpack.
Reset button
A little button is placed over the reset and then the cover can be pressed on top.
