Electronics Projects for Students and Hobbyists
by Lewis Loflin
Introduction - The purpose of these pages is to introduce the student and hobbyist to electronics projects. My hope is generate interest for those thinking about entering a high tech field, or simply to have fun.
Understand some terms right now: a short is an unwanted connection, while an open is a broken connection. For example a blown fuse is called an open because the electrical path is broken; a short is an unwanted connection such as connecting the positive post to the negative post on a car battery and watching it explode. Yes even low-voltage circuits can explode if mishandled.
First and foremost read this safety warning. Unless one wants to use batteries, the only practical solution is a plug in the wall power supply.
Below are quick links to the major sections and projects on this website.
Update Nov. 8, 2013. I've decide to add Microchip PIC projects to this website in addition to PICAXE and Arduino. Using the 18F2550 BOLT system the programs are largely interchangeable with Arduino. I'll be adding some PIC16F628 assembly language projects a well.
PICAXE Microcontroller Projects
The PICAXE series of micro-controllers rank as the easiest and most cost effective way to use Microchip processors. I wanted an easier and less expensive way to introduce my students to the "PIC" micro-controller. Here I hope to get those starting out past poorly written literature and lack of simple working code examples.
Arduino Microcontroller Projects
My Arduino section is growing. For example we can interface the thermocouple amplifier and an LCD display to the micro-controller to display the temperature in say the flue of a wood stove. Again the idea is modular, small projects that can be built into bigger projects. For more technical details on the Arduino see ATMEGA168 Arduino Micro Controller Projects.
General Electronics Learning and Projects
Listed below are pages on power supplies one can build and test. At minimum go buy a digital volt-ohm meter. They are cheap and can be found everywhere from Radio Shack to Lowes. In the You tube video I show how to use what I call a load lamp. This is simply a light bulb wired in series with the project. If one connects something wrong or shorts anything out, the lamp will light instead of blowing fuses or burning things out. It will also give one a quick visual indication something is wrong in order to disconnect the power.
