(I always seem to have more than I use, so cutting one to fit was quick and cheap.) You'll also want to solder a hookup wire
to the switch.
What You Need: * 1-5" long piece of 1/2" PVC plastic water pipe * 2-7/16" long pieces of 1/2" wood dowel * 1-22 ohm resistor (available from Radio Shack, catalog #271-1103) * 1--super bright orange or red LED (available from Radio Shack, catalog #55050629) * 2--AAA batteries * 1--1" long #6 wood screw * 1--3/8" long #6 wood screw * #8 or #10 washer (small washer) * 8" length of #22 or smaller, stranded hookup wire
(available from Radio Shack, catalog #55057523) * small piece of sponge or spongy, plastic packing material * electrical tape * picture-hanger wire (optional) * Radio Shack's web site: www.radioshack.com Making It
* 18-gauge solid (not stranded) hookup wire
from an electronics store such as Radio Shack, or 1/8-inch-thick bonsai wire form a garden store.
It is especially easy to create such an inadvertent short circuit if you are using multistrand wire, so all station wire and hookup wire
going into a wiring block is solid...or it should be.
Electronic wire and cable includes products such as multiconductor cable, fiber optic cable, coaxial cable, planar cable and hookup wire
. Distribution channels for these products include wire and cable specialists, electronic component distributors and a variety of specialty distributors, including cable assembly houses.
It consists of two lengths of ordinary hookup wire

* wood glue * general-purpose cement such as Duco * duct tape * 9V battery * 1--Popsicle stick switch (see below) What You Need to Make the Popsicle Stick Switch: * Popsicle stick or craft stick * 3-3/4" #6 round head wood screws * 1-1/2" 6-32 machine screw * 2-6-32 nuts * duct tape * small piece of foamy packing material Making It Step 1.
At least 10" of #22 or #24 solid hookup wire
(Note: if you purchase Digi-Key's 438-1046-ND, you get both the experimenter board and a 70-piece wire set, which simplifies things.
