It has a very personal feel to it. You seemed to really enjoy the project which makes it a lot more interesting to the viewers. I know I'm not the only one who saw it and thought "I wonder how big of a speaker I could make like that." Instructables and similar sites with mostly pictures are great but they lack the enthusiasm.</p></p>

That was the sound of me realizing that a roll of Kapton tape isn't something a lot of people have "laying around." Incidentally, as a testament to my geekitude: of all the incredible "mistakes" made on the YouTube auto-transcription, the substitution of "polyamide" for "polyimide" is the one that irks me the most... not that I would expect a speech-to-text engine to understand the difference between Kapton and Nylon.</p>

I never put a lot of trust in hot glue until I started doing projects with tight deadlines and was forced to use it as opposed to, say, a binary epoxy, and I've found that as long as you're using a high-temp glue and you know its limitations, it's really great stuff (Not just for arts and crafts class anymore!)</p>

The acrylic was thick and difficult to vibrate so doesn't contribute noticeably to the sound generation, in contrast the paper cup isn't quite as good at vibrating as the thin diaphram but it's much larger and shaped like a cone (so a large volume of air is moved).</p>

You know what's funny is that I spent like an hour on that acrylic, fixed-coil speaker and it performed... well... as expected. Then I built that second one out of a paper cup and I don't know if you can tell in the video but it worked WAY better.</p>

I measured what I called the impedance throughout the video but I was really giving you the resistance, the nominal impedance was probably slightly higher.<p>Measuring the inductance of a coil requires some cleverness. In this case cleverness means math and a good meter.</p></p>

That design was pretty seriously flawed for a few reasons. You're right, an air coil would perform a lot better. As it is, because I didn't have a stretchy material for the diaphragm and I didn't have any easy way to keep tension in it, the magnet's attraction to the core is what keeps tension (yup) so not only is the whole thing dampened, but the diaphragm doesn't keep it's shape in deflection, lol</p>

(hopefully going somewhere fun w/your bride)<p>Nick, nice work on the speakers. They're very simple devices, and at least you got some sound out of them. Maybe the magnets you were using were <em>too</em> strong?</p></p>
