These are standard '130 size' DC hobby motors. They come with a wider operating range than most toy motors: from 4.5 to 9VDC instead of 1.5-4.5V. This range makes them perfect for controlling with an Adafruit Motor Shield, or with an Arduino where you are more likely to have 5 or 9V available than a high current 3V setting.

Two wires are used to control/power the vibe. Simply provide power from a battery or microcontroller pin (red is positive, blue is negative) and it will buzz away. Works from 2V up to 5V, higher voltages result in more current draw but also a stronger vibration.

First, count how many positions you want as the final piece, then pull out the next pin using a pair of pliers. Finally, cut through the empty spot with diagonal cutters. You can clean off the half-spot using a file or with the diagonal cutters. These are 'standard' female 0.1" headers such as used on dev boards like the Arduino. If you have something with 0.1" square-pin male header on it its almost certainly going to match with these (the only exception is 'round' swiss-pin headers, but those are not as common).

The PN532 is the most popular NFC chip, and is what is embedded in pretty much every phone or device that does NFC. It can pretty much do it all, such as read and write to tags and cards, communicate with phones (say for payment processing), and 'act' like a NFC tag. If you want to do any sort of embedded NFC work, this is the chip you'll want to use!

Sew a couple inches into the pad of your gloves to keep your hands toasty while you use your iPhone, iPad or any other device with a 'capacitive' touch screen. Because capacitive sensors sense your finger through conductivity, not pressure, they don't work when you wear your gloves - they act as insulators.
