My son, Antonio, has reached the midpoint of his work with the Radio Shack Electronics Learning Lab I wrote about last November. Just a few days ago he finished the first of the two workbooks (click here to view PDF). I really liked the second-to-last of the labs — a “fully adjustable siren.” Here’s the schematic, followed by my son’s take on this part of his homeschooling curriculum:

The End of Book One of the Learning Lab

The last lab of book 1: a frequency meter using 555 & 4046 chips.

I have reached the end of book one. It has taken me six months to complete the book. The things that I have learned are both great and valuable. To be able to understand parts (such as resistors, capacitors, and different types of ICs) has been a great help.

It has been a real joy to have my dad help me with my projects. We both learn something new each time we do a lab. With this lab you learn how to put together circuits. You also learn to think about what the circuit is doing. Once you really start to understand the basics you are able to figure out parts of the projects without looking at the step-by-step instructions.

Grade: A!

This lab kit has so many neat and interesting projects. You get to build things like light-dark meters, adjustable sirens and so much more. By using this lab I am able to build a code oscillator and many other useful things. Anybody who wants to know more about electronics or who has never learned about them should consider getting one of these lab kits from Radio Shack. Once again let me just say that I have really enjoyed working with this lab.
