Step 1: What You Need
-Piezoelectric buzzer, mine is quite large and came from a telephone ringer
-Some wire, both stranded type (if your leads from the piezo element aren't long enough) and safety wire (if you want a super ghetto attachment system like me)
Step 2: Connect the Leads
Now, connect the black lead to the part of the 1/4" phono jack that is like a ring; the ground. Next connect the red one on to the part that connects to the J looking thing; the positive.
You should end up with something looking like this \/
Step 3: Removing the "lid" Off the Can.
The way I did it was to sand lip on the drinking side on a belt sander until the "lid" relased. If you don't have a belt sander, well, figure something out, it's not to hard.
Step 4: Cut a Hole in the "lid"
I traced out my buzzer first, then started a cut with a dremel, but then I got lazy and just ripped it from there (beast, I know). I of course cleaned up the jagged rip marks with a sanding bit.
Then test fit! Cool, it fits!
Step 5: Put a Hole in It.
Then just put the jack through, and screw on the nut, good and tight!
Step 6: Affix the Piezo and Top, Ish.
Now to attach the top, I just got four holes in the top and soda can (so that they sorta match up) then strung safety wire through the holes and twisted, and such. It looks ultra ghetto, and kind've cool.
Step 7: Mounting?
Easy, just poke a hole in a side that's smaller than the threads on your mic stand (when it has the mic clip part unscrewed off of it). Then it should thread on, ish.
Step 8: Done!
