Final Musical Machine Design --- Ocarina

First of all, we have to apologise to those who keep paying close attention to our musical machine project. We couldn't finish the machine in summer because of some delay in the manufacturing process. But we promise you guys we are going to work much harder on the machine during term time. The final musical machine will be finished in approximately three weeks next semester. Thank you all for keep following us!

In this blog, I will illustrate what we have we accomplished in this summer holiday. As I mentioned before, most of the delay was in the manufacturing process. To be specific, we were lack of materials, which lead to the delay of the whole project. But we still have finished few parts of the machine, which are shown as follows:

Firstly we have finished the whole plan for the final machine. The graph is shown below.

The final machine will have six independent parts, which are ocarina part, big wheel part, guitar left hand part, guitar right hand part, drum part and xylophone keys part.

The first part is the ocarina part. This part is almost finished. The only that needed to be added is the support for this part. The main part of the ocarina is consisted of 7 ocarinas, some laser cut acrylic parts and 3D printing parts, 18 meters’ clear pipe, four foot pumps, sponge and some tapes and glue. The big wheel consists of a 25.4mm aluminum hex shaft and several acrylic wheels. The pictures are shown as follows.

As for how do they work. Firstly, the big wheels on the shaft will be programmed by insert some 1 p coins. There are 96 ruts on each wheel and should play four beats a round. Then one person should step on the four air pumps when the big wheels are rotation above the 7 ocarinas. We find out there is a mute system for ocarina, which is when the specific outlet hole of the ocarina is blocked, it will stop making sound no matter how much air go inside. So, I made something by laser cut acrylics and sponge to block those holes of 7 ocarinas. When the programmed 1 p coins on the wheel unblock those holes, the ocarina can play music as we programmed. Each ocarina would play one specific sound.

The rest of the machine parts will be updated later. Please keep paying attention to our project. Thank you very much!
