Electronic Canary

This instructable will cover all the basics involved in building an electronic canary. This is a excellent weekend project. This circuit recreates accurately the sound produced by a canary.
All components for this project should cost under $10
Basic soldering and electronic skills required

For a preview for the sound it makes. The file is below the picture.

Hi I'm am currently trying to build this circuit with a pcb that I designed but I can't find an audio transformer nowhere, I found a couple of old radios and nothing radioshack doesn't have them either, wherebcan I possibly find it? Thanks!!!

A 47000 ohm resistor is yellow, violet, orange, tolerance A 4700 ohm resistor is yellow, violet, red, tolerance

is there a site with all of that stuff on it(the resistor codes) and all? i have alot of them on a piece of marked cardboard but i don't want to take them off cause i don't want to mix it up

Try http://wiki.xtronics.com/index.php/Resistor_Codes or search for "resistor color codes."

Get a breadboard!

[cd41]

they aren't necessary for everything plus this way you can put it w/e you want not just where the board will fit

if i really wanted to, i could make this into a a cube with the area of 1in³

yeah i know. i saw this online and i had to build it. All i had around was copper foil tape and a plastic board. I couldn't be bothered going to buy a prototype board so i built it. It looks a bit messy but it works
