What I should learn during this week assignment - Define the scope of final project. - Develop the project plan.
During the previous week I have change the idea of my final project, as in the first weeks of fab academy I decide to make Robotic Fish but I change it to musical instrument called Semsemya it is an Egyptian traditional musical instrument,so I decide to to make some improvements on it to make it electronic instrument where any one can use it easily and enjoy playing with it.
This video show how it work
It is a musical instrument that will be made from wood where I can make the frame using shopbot and I will use photo transistor as input and laser beam as output.
The idea is that the laser beam is in the direction of the photo transistor when I put my hand between the laser beam and the photo transistor the resistance of the photo transistor will changed,so now I finish the part of the electronics.
The next step is networking as I want to read the value of the resistor on the pc using serial communications.
The next step after finish networking is the time of processing I will use processing.py to translate the value of resistance to specific sound.
Now by changing the rope I put my hand on it the sound will change.
At first I think to make something that related to our traditional, I find that we have a traditional music instrument so I think to make it with digital fabrication and to make it electronic. so alot of people who love it can use it and learn it easily.
SO after I have an idea I find alot of similar instrument but I did not find one typical to mine.
This links of people who make instrument similar to mine
- laser harb
- Build your own musical instrument
- Easy laser harp
The outer frame I will make the design consist of multi layers frame using Fusion-360 and export it inDXF and by knowledge I have learned in week 3 Computer controlled cutting I will cut the frame using the laser cutting machine.
The holder of the instrument I will make it using Fusion-360 and export it in stl format and 3D print it, in this part I will use knowledge I have learned in week5 3D scanning and printing
The logo of instrument I will make it using corle draw software and then cut it with vinyl cutting machine. For this part I will use skills I have learned in week 3 Computer controlled cutting I will cut the logo and stick it to the instrument.
Designing the circuit board for this part I will use kokopelli software and mill it using the cnc machine and solder the electronic component, For this part I will use the skills I have laerned in week6 Electronic production for making the board.
Programming the board for programming the I will use the skills I have learned in week 8 Embedded programming
Using the analog to digiatl conversion to take the raeding from the photo resistor, I will use skills I have learned in week10 input devices
The main question need to be answered is
- how to know the specific tone for each robe to use it? - How to use processes.py with attiny44?
The evaluation is that I succeed to have different tones from the instrument.
