I can just imagine how conductive paint would improve a project like this, my latest creation is a signal generator, and instead of running wires I could paint the wires on the plastic.
This project is a green project because of the salvaged circuits and the reuse of candy boxes.
Step 1: The Candy Boxes
My wife thinks I am a romantic giving her chocolates all the time, now she knows I want the boxes but she still likes getting the Bon Bon’s. I open one of these boxes of Bon Bon’s and before I can say Bon Bon’s their gone between my wife and sons, I am lucky to get one.
Step 2: The Signal Generator
It has two independent outputs, one for sine wave and the other for square wave. The circuit can produce frequencies from approximately 40Hz to 2.5KHz or from 2.5KHz to 10KHz depending on the position of the range select switch. The sine level can be adjusted from 0 to 2V peak-to-peak through a trimmer potentiometer. The square wave output provides two separate fixed level outputs, one at 5V and the other at 9V.
