Trombino | WIZnet Makers

details

The Trombino is an electronic Trombone based on the Arduino platform. It comes in two flavours, one using a wind sensor and one using a traditional trombone mouthpiece. As well as outputting sound you can also get OSC and MIDI data from the Trombino. It has been made to be used as a learning aid for children, but would be also interested in musician looking for an interesting new interface device.

Let’s see the demonstration first. It’s so unique~

For this project, below parts are mainly used

– Arduino Uno

– Arduino Ethernet Shiled

– Arduino Box

– Wind Sensor

– Piezo vibration film

– Kelly plastic trombone mouthpiece

– Innards from a Gametrak central unit

– 3.5mm audio jack

Step 1

Open up the Gametrak, unplug everything and remove one potentiometer and sliding tower block. (I forgot to take a picture of this, image from here: http://janoc.rd-h.com/archives/129)

Step 2
Use epoxy to glue the tower to the potentiometer casing. If using a wind sensor solder long wires to the V+, GND and OUT pins of the wind sensor. Seat it in the gap it magically fits perfectly into as shown below. Tidy your cables! I pleated mine and threaded them through the hole created where the tower and potentiometer housing meet. I also created a handle with polymorph and attached it to the underside.
Step 3
For the wind version… Solder parts for the button board onto a small piece of stripboard. The schematic for the layout can be found in the Fritzing file on the projects github repository. Cover the back and sharp edges with Sugru.
