How to Turn Your Initials Into a Circuit

This project uses fairly common parts that can be found at most places (with the exception of some of the sensors).

General parts:
--20mm coin cell (Sparkfun[currently out of stock], Radioshack)
--20mm coin cell holder (Sparkfun, Radioshack)
--3mm LED (Sparkfun, Radioshack)
--Button (Sparkfun)
--Copper tape (Sparkfun, Amazon) or conductive ink (Bare Conductive)

Tools:
--Card stock paper or thin cardboard (I am using card stock throughout this instructable)
--Pencil
--Hobby knife or scissors
--Breadboard
--Jumper wires
--Soldering iron
--Solder
--Helping hands
--Multimeter (optional, for debugging)

Sensors (there are many possibilities):
--Photocell (Sparkfun, Radioshack)
--Thermistor (Sparkfun)
--Flex sensor (Sparkfun)
--Trimpot (Sparkfun)
--SoftPot (Sparkfun)

(The description of each sensor is in the next step, or check sparkfun for a better one.)
