Weekly Project: Noggin Logger--A Wearable GPS Data Logger

Step 3 Cap It

Route the embedded antenna through one of the small eyelet ventilation holes in the top of the baseball cap. Plug the antenna into the bottom of the Lassen iQ module. Snap the module onto the PCB connector.

Cut an oversized round piece of scrap fabric for the liner of the baseball cap. This piece of fabric should be big enough to cover the entire GPS Logger V1.1, plus add a seam allowance of 5/8-inch around the perimeter of your scrap. Slowly roll this seam allowance toward the inside of the fabric swatch, press it with an iron, and stitch it down.

Line the inside of the cap's peak with some Velcro Brand tape hooks. Make sure that you have ample hook pieces for holding the GPS Logger V1.1 and the fabric liner. Attach Velcro Brand tape loops to both the underside of the GPS Logger V1.1 battery holder and the bottom of the fabric liner. Press the logger into place, then install the fabric liner.
