Thread LEDs

Pass the wires through the channel and out of the holes on the sides of the headband part. Carefully bend the wires to angle the LEDs.

Glue Diffuser

The wired LEDs are threaded through the built-in recesses and hot glued in place to create a diffuser.

Trim Glue

Once it’s cooled down you can use a hobby knife to carefully trim away the excess and square it up so it looks nice and clean.

Elastic Band

Measure and cut a strip of an elastic band to fit your head. Use metal Pinch Crimp Ends and fit through the slits on the headband. 

Attach Case

The strap can then be threaded through the battery case.

Mount Board

Align the board to the standoffs. Secure with M2.5x6mm screws.

Add coin cell

Attach a CR2032 coin cell battery and test the circuit using the on/off switch.

Assemble switch 

The button actuator press fits into the top cover and gives you much better access to the breakout boards slide switch.

Attach Lid

Snap fit the cover onto the case with the LED wires inserted through the built-in slit on the side.

Hide wires

The wires are hidden behind the elastic strap and sewed in place with a few stitches.
