Electronics for Beginners

Now Back When I Was a Boy!

When I was very young, my dad took my brother, Aaron, downtown in SLC. I tagged along. We went to a an electronics store and bought some copper wire and some insulators. Then we walked back home for a total distance of four (4) miles and Dad and Aaron strung a wire high overhead between the garage and the house. I was too little and two tired to help, but I was very excited. It was an aerial or what we call an antenna.

Inside, Aaron chipped a small piece from a piece of ore my grandfather had mined. Well, he hit it with a hammer. He put this on a wood board along with a coil and a variable capacitor. He hooked up his headphones and lo an behold, he could here the local radio stations.

I made many such crystal sets over the year. I looked around for junk radios and took the parts. I soon became an expert and my finest hour was when I made a radio that could clearly separate nine (9) stations.

Here was Englands finest hour at that time:

A Point Diode

To make a piece of metallic ore work in my radio, a small wire must be pointed into it. It formed what we now call point contact diodes. When my kids were young, I just bought diodes and used them instead of the ore.

But there was something fun about knocking out a miracle from a piece of ore in those early days.

I studied electricity as an undergraduate in college. Then as a graduate student, I studied not only electronics but the physics of the solid state which included many electronic devices we find common in this day.

I am an amateur radio operator so I still have an interest in electronics her in my mid eighties.

It cost me nothing to get started in electronics. So I’m giving you a link to a free course. I am also giving you details of a low-cost electronics course which will be more personal and more fun.
