noisemaster-0216

In our introduction post I mentioned NoiseMaster 3000 and all of the noisemaking devices we built. Well, here’s another one in the series.

While I used wood for the first one, I chose MDF for this one. MDF has some nice qualities, like being smooth and consistent in surface and size, but besides all that, it’s terrible. Actually, I should say that I’m terrible when it comes to working with it. It’s not like wood, which is forgiving, and I seem to split MDF whenever I use it. I find it annoying, so why not work with it for a project that doesn’t matter that much, so I can try to improve my skills a bit. Good idea, right?

This one again makes use of an ATtiny (I have like 20 of them) and I sort of liked this design when I built it. You’ll notice in the photo above that the screws holding the speaker in place are at a weird angle. That happened in transport, and was not planned. They were actually straight when I built it, but being piled in a bin with a dozen other noisemakers and other things caused a little damage.

You can barely see it, but this one introduces something that will show up in future posts… 3D printed parts. It’s just the standoffs in this case, since I used all the laser-cut standoffs for the last one. Again, all electronics and wiring are exposed, by choice.

I used a lot of screw terminal blocks, typically for power input (though sometimes for speaker output.) Like anything you make, if there’s a chance someone besides you might use it (or if you forget things) add labels! I did not add the ‘+’ and ‘-’ to this, as I know that when I use two wire colors the darker one is always ground and the lighter one is always positive. Maks and Dustin didn’t know that, so they traced the symbols from the PCB and added the labels.

This one once again remained pretty raw. I left the MDF as-is, and did not paint it or otherwise do anything to the surface. I was still just focused on building things quickly. (Don’t worry, that changed a bit as I built more of them.)

This is just one post in a series about noisemakers. Check out the other posts as well:
