The following is my Computer Science project Comp490 and Comp492 in progress. It is a SUMO robot for our local RoboWar tournament. I have been, for the pass two years a participant of the annual RoboWar competition. So, this year I've decided to try to get credit for doing it.
"I was fortunate enough to find a professor who was willing to supervise my project Dr.Ferhat Khendek. I have decided to do the documentation in HTML format and make it public to anyone who is interested in robotics."
There are two class of robots, remote controlled and autonomous. Remote controlled are operated by a human participant via RF link. Autonomous on the other hand has to be self contained with no human influence in its operations with the exception to its programming.
This is a nice educational reference project based on 89C2051, an 8051 derivative. This uses the Uses analog switches to steer test tones and results. Programmed in assembler to produce pure 1khz tone.
"The example meter that we are demonstrating is typical of many economical digital multimeters that you can purchase, hopefully these instructions will be of some use to you no matter what brand or type of meter you use. "
Students and Hobbyists can study all the example projects and tutors in this site to become more skillful. They have pages that show how a PCB is made and things like Circuit Design and Prototyping. This Site also happens to be one of the oldest resources in the web for Electronic Embedded Designs.
Solder your ArduTouch kit together, and it works! You can make way wonderful music, sound, and noise.
Use the ArduTouch Library or hack the existing sketches to create your own cool synthesizers.
The documentation is getting good enough to learn how to use Digital Signal Processing (DSP) to make your own sounds for your own projects.

First have a look at this How to Build a Robot a BeetleBot. This sparked the long lost memory of a book i read around 35 years back. My age was in single digits. This was when i had neither an idea of electronics or could afford any parts.
I had built many physics projects like weighing scale, gramophone, telegraph system, crystal radio. I will try to explain these later. Calling bells, gears and magnets from the flea markets my source of electricity & magnetism.
I read a hobby book from UK for children. It was a Beetle Car Bot, with four wheels and 4 light sensors. It could be LDR or photo-transistors, i do not remember. The light sensors were at the four corners of the car. The maneuvering was by variation in the speed of each wheel. It was based on germanium transistors mostly.
Four large lamps like 40W, had to be mounted on the ceiling, at the four corners of the room. By turning on and off these lights, this bot could go anywhere in the room. The whole book with pictures was dedicated to one bot and how-to build one.
Now that we have PIC and AVR; we can use Dimmable LED Lightning arrays to guide the bot. The challenge is in the mechanics of the bot, we have to forget that we have wireless for some time. Try this out.
Gainclone or chipamp is a type of audio amplifier made by do-it-yourselfers, or individuals interested in DIY audio. It is a design based on high-power integrated circuits, particularly the National Semiconductor Overture series.
The Gainclone is probably the most commonly built and well-known amplifier project amongst hobbyists. It is simple to build and involves only a few readily accessible, inexpensive parts. As an amplifier it is highly regarded by many in the DIY community.
"The amp is based on the Project 19 PCB, so uses a pair of LM3876 (or LM3886) power opamps, run from a ±35V supply. ...........The power supply is conventional in almost all respects. I used a 160VA transformer, a 400V 35A bridge rectifier, and a total of 20,000uF per supply rail - 4 x 10,000uF caps in all."
"The Gainclone amplifier has proved very popular with hobbyists since construction is straightforward and the resulting amplifier has an impressive performance specification.
"But it was the Gaincard that caught the imagination of audio diy-ers around the world and before long, copies of the Gaincard were appearing on internet sites and discussion forums. The Gainclone was born!"
"I had previously planned to build a small stereo amp using the amp6 kit from 41hz.com. After deciding I wanted a bit more power, I did some research and am now going to build a so-called gainclone amp based on the LM3886 chip."
"This is a hifi audio amplifier I built based on LM3876 audio amplifier chips - which have a web following known as "Gainclone" amplifiers. I built this amp to be my main stereo amp in my home recording studio, and it is optimised for very good sound quality and (hopefully) reliability. :)"
