What a Difference 50 Years Makes – The Elegoo Kit

When I was 14 years old, I was into “designing computers.”  I bought a book about computers, studied it, and started drawing logic diagrams, cobbled together logic gates to perform the basic arithmetic calculations on notepads. To test them, I used a transformer from my slot car track, bought little lightbulbs and sockets to represent binary memory registers, toggle switches to enter binary data into the system, and wired the various gates using tiny wires and Molex connectors. The stuff was mounted on a 4 by 4 foot sheet of plywood. I got as far as creating a working system to perform multiplication from 1 x 1 up to 10 x 10. I had built a computer.

Today I received the Elegoo kit. This is a kit based on the Arduino processor.


For less than sixty dollars I received a huge amount of components with enough computing power to rival the mainframe computers of the 1960s. The whole thing comes in a nice plastic case the size of a large coffee table book.

Now I just have to build something.

When I was 14, I had all the time in the world. Not so much now!
