Lesson Plan for Making a Speaker Laboratory. ©1995 The Regents of the University of California by Regan Lum Introduction: A speaker is a device that converts an electronic signal into sound. The speaker you will build (see figure 1) consists of a Styrofoam or paper cup, a coil of wire, a permanent magnet, and a signal source. The electronic signal goes through the coil and creates a varying electromagnet. The attraction and repulsion between the electromagnet and the permanent magnet cause the cup to vibrate and produce sound. figure 1 Purpose: In this laboratory, you will explore how a speaker works.
Materials: 1 permanent magnet 2 feet of wire 1 pencil tape or glue 1 Styrofoam or paper cup 1 signal source (tape player) 1 plug with alligator clips for tape player Procedure: Assemble material as shown in figure 1. Leaving about 10 centimeters on the end, wrap the wire around a pencil to make a wire coil and tape or glue it to the bottom of the cup. Conclusion Does the volume control on the tape player work on your speaker? Amp Up a Laser Pointer. From Wired How-To Wiki Illustration by Lab Partners Your laser pointer could be doing so much more than highlighting PowerPoint slides and blowing your cat's mind. It could be sculpting ice, sparking campfires, or searing one bad mofo on your leather jacket. Here's how to give a standard pointer a power upgrade.
This article is a wiki. Got extra advice? 1 Disassemble the unit by removing the batteries, opening the housing, and taking out the laser module. 2 Search the circuit board for a variable resistor. 3 To intensify the beam, use a small screwdriver to gently tighten the resistor. 4 Reassemble and aim your potent pointer at safe targets like ice, wood, or plastic.

If we use two rechargeable AAs that put out a total of 2.4Vs we're going to need a solar panel that is at least 3 - 4Vs just to meet basic levels of charging. The higher the voltage of our solar cell (or cells) the less light we need to charge up our batteries.
Now we're also trying to fit this into an Altoids Tin, so we're limited in space. I have found some great 4V solar cells that perfectly fit into Altoids Tins. They're the same ones I use with my Solar AA Altoids Charger. Sure, a bigger and better solar cell would give us added power, but it wouldn't fit into our tin. You could also use a combination of several smaller cells to get your four volts. Just remember that when charging NiMh batteries we don't want to throw more than 10% of their capacity at them at any one time. Solar Altoids iPhone/ iPod Charger. I love my iPhone 4 to death. I really do. Even if it sucks juice faster than a 1st grader at snack time and I often find myself on low power with a long train ride ahead of me.
I originally made my Altoids USB Charger to use with my iPhone, only to find that Apple being Apple doesn't let it's products play nice with generic USB chargers. I then set out on a long journey to find a cheap charger that would work with an iPhone 4. It's a cheap and easy project to put together and a great gift to give. *** Update: I've since retired this kit.
