Picture of From Candy Boxes to Proto Boxes
Proto Box 2.JPG
I salvage electronics for parts and projects and I like clear proto boxes to put my projects into, that way I can show off my work. I can never find proto boxes in the store when I want one, let alone clear proto boxes that let me see the internal components until one day I spotted some candy in the store.

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

These candy boxes from Ferrero Rocher are designed to show off the candy and they make great proto boxes coming in a variety of sizes just the right dimensions for small circuits and other components. The best part they cost less than a proto box and you get a treat.

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

Picture of The Signal Generator
My wife got me this signal generator circuit from Canada Kit, as my Christmas gift. The circuit is based on a Wien-Bridge oscillator, which provides a sinusoidal output in a sine and square wave in the audio frequency range. It is also an instructional tool that can be used to display waveforms on an oscilloscope.

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.

could you make an instructable for the signal generator

Not right now cant up load picks.

Mu wife got the kit from Canada Kit:


Yeeah dude ! I do exactly the same !

You also have a proper Sweet Tooth in addition
To a green_screen electronics thumb combined
with those very dexterous hands ;-)

just a little one
Would we recognize each other if our paths crossed in a sweets shop ?

You would have a better chance of recognizing me I am visually Impaired.

I do this all the time.

Isn’t that wicked EH?

Proto boxes are a pain to find let alone transparent ones don’t exist.

The candy box filled with candy is half the price of a proto box and you get a sweet treat to boot.

I like to show off what I do and they are perfect for showing off your electronics and protecting them at the same time.

The only thing is they are very EMP susceptible.
Maybe you could protect the circuits from EMP using metal desplegado. There are some of them very nice.

By the way, you can help me telling what is the English name of that "metal desplegado". Google translates it as "expanded metal", but I do not trust.

All translators lack of technical translations: tools, procedures, materials, etc, are often very difficult to find.

Thanks, Josehf.

Good idea, Josehf.
