Ultrasonic Music Control

Right now i try to crreate a case thats stylish and also cheap to print on shapeways for example.

I will add later more information...

The next step is to create a 3D printed case for the PCB and the sensor. But to do this i first created a 3D model of the hole assambly to thest everything first. And as it turns out it really was a good idea:

As you can see i forgot the mounting holes in the PCB...

For the 3D software i use SolidEdge as i learnd how to use it in shool and is aviable for free for students.

Ofcourse i have to publish the cuirit diagramm so others can easily build their own Ultrasonic switch:

at the moment im working on the layout for the pcb. I decided to use smd components as you can see in this picture: 

With these smd components i can get the hole thing fit below the HC-SR04 sensor. But still i need a double sided PCB, and ony have exposed pads as programming port...

But on the otherhand beacause the PCB is that small it will be very cheap to manufacture in china :)
