In our introduction post I mentioned NoiseMaster 3000 and all of the noisemaking devices we built. We’re now up to number three!
This one has a more unique look, due to the material I used. I believe the “wood” is actually Bamboo, as this was an old cutting board that we replaced years ago. I didn’t toss it because I knew at some point I’d use it for a project. (See, I do have plans for those things most people just throw away!)
I also used some square dowels and a very small red momentary push button. Again, pretty much everything is exposed, though I did at least countersink the screws. The large hole was there when it was a cutting board, and I drilled speaker holes. and then used a countersink bit to give them an angle. (I think the rough edges are due to it being Bamboo.)
This one also features 3D printed parts. Little green standoffs were used for the PCB, and also for the speaker, so the screws could be the appropriate length. And once again an ATtiny85 powers the noisy noise. (This one is even more annoying than the previous!)
This is just one post in a series about noisemakers. Check out the other posts as well:

I have some fun ideas for how the software for these could be tweaked, or how it could do more with a simple IR sensor and IR LED. Maybe the software could be on a really big loop that slowly changed the pitch of the noise? Say, over an hour?
The IR receiver and IR LED idea is orthogonal: Add in rhythm and let the noisemakers that can see each other “sync up”. There’s some simple ways (algorithms) to have them converge on a beat, like a swarm of fireflies.
mathiasx, sounds like you should join us next time! :)
