You'll need a FLORA! If you have the Flora GPS Starter Pack, you already have most of the parts, just pick up a simple pushbutton and adhesive pinback.
You'll need two IR LEDs, two NPN bipolar transistors like our PN2222s, two 100-ohm resistors, a simple pushbutton, a 3xAAA battery holder or lipoly battery, some hookup wire, heat shrink tubing, and an adhesive pinback.
Tools! You'll also want a soldering iron, solder, wire strippers, flush snips, a panavise or helping hands, a lighter or heat gun. To make an embellishment for your project, grab some fabric and sewing supplies or tools and materials needed for your craft of choice (crochet? knit? felt?)-- anything goes.
