Some things you can find there -CB & Ham radios, Walkie-talkie (GMRS/FRS) radios and Shortwave & multiband radios.
The company was started as Radio Shack in 1921 in Boston, Massachusetts, by two brothers, Theodore and Milton Deutschmann, who wanted to provide equipment for the cutting-edge field of amateur, or ham radio.
Theodore and Milton Deutschmann opened a one-store retail and mail-order operation in the heart of downtown Boston. They chose the name, “Radio Shack,” which was a term for the small, wooden structure that housed a ship’s radio equipment. The Deutschmanns thought the name was appropriate for a store that would supply the needs of radio officers aboard ships, as well as “ham” radio operators.

“I present, below, a collection of projects I have worked-on over the past few years. For over a decade, I had taught both embedded systems (microcontroller technology) and digital signal processing and practice what I preach….”
Nixie Thermostat – A heating and cooling thermostat employing technologies spanning fourty years from the unique Nixie tube display, circa 1960’s, to a PIC 18F microcontroller, circa 2006.
A High-Powered Power Backup Inverter – The working prototype of the 2 KVA inverter is complete. Fed from an array of lead-acid cells totalling 600 Ah (at 12 Volts), it easily drives real-world loads such as single-phase motors. The inverter has been tested and found to operate at an efficiency of between 71% and 82% driving a variety of both inductive and resistive loads
It’s a 360 degree multifunctional programmable sensor that has a bundle of cool features for sensing for your Maker, Robot and Kinetic art type projects.
The sensors is also packed with two ambient light sensors (for light tracking experiments or line following) and IR remote control functionality so it can can read and transmit Sony SIRC IR control signals.
The sensor is designed to fit onto micro sized robots (50mm x 50mm) where 360 degrees of proximity sensing, ambient light sensing and basic inter-robot communication is required, such as robot swarms, robot research, robot gaming and robot sumo competitions.
This site is offered in the hope that readers will better understand electric guitar technology, leading to creative use of your musical tools. Of course, only practice will improve your musical vocabulary and articulation….
“Hello World! I live in Adelaide, South Australia, and my interests are electric guitar, playing live music, writing MIDI sequences, programming in Visual Basic, dabbling in electronics, with a casual interest in popular science. I have some years of experience in these fields, and use these Web pages to share my knowledge freely. ..”
Most musical instruments and their amplification systems, such as those used for public address (PA), recording and hi-fi are designed to reproduce sound as accurately as possible. Electric guitar and its amplification is completely different: every item in the guitar signal chain is designed to modify the raw guitar signal in some way.

A Typical Hardware Hobby Enthusiast is a Hacker when he starts learning, it is sometimes given the name of reverse engineering in another context. The Hardware Hobby Freelance hacker is better off, he is doing it for Learning and Education. Students should be given new and challenging projects in well equipped labs, to augment their skills and make them productive in their jobs from day one.
Hobby Projects – Insulation tester, LED Circuits, Meters.
We all learn by breaking up things, to see how it works, then Fix things around Home etc. Later Create and Innovate perhaps, thats the way to go. To Invent something someday.
Here are some people doing just that, inspire you to create useful things for your Home. We should never become over dependent on others for everything, this will erode our knowledge base, skills and freedom.

It is by Hobby and DIY – Do it Yourself, Education Starts even without books. Then you need to read to enhance your abilities to Design your own.
In order to compensate or enhance your education, you need to work at a small shop as an apprentice even as a student, not for the sake of project work alone. An Evening job at a factory or a home mini workshop-lab is very essential for obtaining the skills – Solderman 1702
