NXT Trumpet

[Jetro]

I got my hands on a dPressure sensor from Dexter Industries some time ago and started thinking about how I could use it in a slightly less obvious way than for example datalogging or monitoring a Pneumetics circuit. Of course Pneumatics is the way to go so I started toying with the different elements and the sensor until I came up with this:

The red piston is and old type Pneumatics pump (only diferent from the old type single acting cylinders in that it has a return spring) which is directly connected to the positive presure port of the sensor. Add three touch sensor and a bit of programming and you have an NXT trumpet:

Now just need to learn to play it better

How cool! I am usually not interested in Technic, but this stood out to me since I play the trumpet. I have thought about electric trumpets before, but I never could figure out how to make one. Is there any way to change your octave while playing, because it looks like blowing does not affect it. Great job!

I've also played the trumpet years ago, and it's safe to say there's never been one like that

How unique! Maybe musician Jurgen Krooshoop can compose a Lego Technic song to play on this!

As you can see in the furst part of the video, pressure on the mouthpiece (simulating "blowing") si what changes the harmonics. I have only included the first 5 harmmonics in the program but a second octave could easily be included although it would be more difiicult to precisely appy the right pressure and get the tone you want.

This MOC is so unique and original. //Standing and clapping hands, shouting: BRAVO!//

I am looking forward to some new songs.

That's one truly unique creation you made there. It's a use of the pressure sensor most people wouldn't ever think of, I've just discovered you placed a topic about here, as I've seen the video on Youtube a while ago already.

By the way, you're also featured on Technicbricks blog (http://technicbricks.blogspot.com/) with this creation.

Thats amazing! As a trumpet player I have to say you have done the best you have done and the results are great!

Nice work.
