Electronic Projects For Beginners
I made a guide for those people who are still starting with their electronics hobby. I started connecting wires, batteries, bulbs, buzzers and motors when I was 4 years old . Now that I am 13 years old, I now have a good amount of experience to build complicated electronic circuits. Learning electronics isn't that easy but if you put love and passion to it, I assure you that you would enjoy building your own experiments. It took me hours to finish making this guide since there is no software editor in the Sibmit>Guide in the "Submit Instructable Section" I had to type every word and picture using HTML codes which I learned from school. These are my all time favorite projects in instructables, I find them simple and easy to make.

How to make a tool set
Life without tools is barbaric. But even simple tools can be expensive in rural parts of developing countries. Import duties bump the costs up higher than they are in the States or elsewhere, and sometimes only low-quality brands are available anyway. So, to hold off future barbarians, we'd like to show how to build a simple tool set on a very low budget. Larry Bentley, the man who figured out how to make these tools, said a wise thing: "Without tools, kids don't take stuff apart, and without taking stuff apart, you don't learn how things work." These tools, Bentley says, could be in the hands of the next William Kamkambwa,who made a working wind power generator from backyard scraps in a village in Malawi. Here's Larry's quick guide to DIY tools. The tools in this guide: Saw Pliers Wooden vice Wood drill bit / star drill bit Chisel Strap hinge vice

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. 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? Return to CEA Science Education Home Page
Antique Strongbox Protects Itself With Mechanical Loaded Pistols
Imagine a bank vault that handcuffed every John Dillinger who walked in through the door. Nothing like that quite exists, but this Russian strongbox, circa 1815, comes pretty close. The antique dealer Carlton Hobbs LLC has acquired a nineteenth-century steel safe with a complicated lock system, capable of firing two pistols at an unsuspecting intruder. According to Dana Donadio, senior decorative arts researcher at the gallery, "Of the strongboxes produced during this time, this one is by far the most complex." The upper safe is a small raised box with a keyhole hidden on its top. While the box is believed to have come from workshops in Tula, a city just south of Moscow, the secrets it kept are unknown. Of course, differentiating what is and is not a true antique is the toughest part.
Build a Laser 3D Printer - Stereolithography at Home
Here is how to make a Stereolithography 3D Printer. It is still a bit of a work in progress but so far it is working pretty well. This is mainly an experiment which started as a Delta Robot Stereolithography Printer but ended as a more traditional Cartesian Stereolithography Printer. "I'll be honest, we're throwing science at the walls here to see what sticks. No idea what it'll do." - Cave Johnson Stereolithography (SL or SLA from Stereolithography Apparatus) is an additive manufacturing process using a vat of liquid UV-curable photopolymer "resin" and a UV laser to build parts one layer at a time. I have wanted a 3D Printer for a while now and there are some very reasonably priced kits available like the Makerbot, Ultimaker and the RepRap project. I decided to enter this in the Epilog Challenge Contest because I could really use a laser cutter :-) I also have some ideas how to redesign this project, for creation on a laser cutter. This project is Open Source Hardware.
