Goals:
Plan and document a final project that integrates the range of units covered:
What will it do?
Fab Sailor is a maritime platform that will send data from the sailing boats to a computer based in the beach in order to produce music. The idea is that due to the movement of the boat, the Fab Sailor installed on it, will send data of an accelerometer to any computer in the beach.
Who's done what beforehand?
There many projects realetd to generative music; and also many that of them are mixing natural movements to create sounds and perfome music. Since many years ago, lots of people tried to figure out what's the sound of nature; In the case of maritime project I have paid attention to a project called Whale, where they make music out of a boay.
What materials and components will be required?
Components:
A case, including:
Electronic Boards: a hello radio board modified
Electronic Board: an accelerometer board
The case will be made out of acrylic.
Joints of the case: made of PLA
A mount for the case: made of PLA
Lap top, speakers.
The boat where this equipment can be installed is not important it can be any. In my case I chosed an small sail boat due to the proximity of this kind of boats to the lab.
I have chosen the boom as the place of the boat where the case and the whole equipment will be easily mounted and it will remain visible as well.

where will they come from?
The case will come from some acrylic that was bought in the lab, most of the boards and materials come from the inventory and little materials from Digi Key that were not in the inventory like caccelerometer, some capacitor, inductors, etc.
how much will it cost?
The whole equipment, including the acrylic case, will cost under 40$ aprox.
what parts and systems will be made?
Electronic boards will be made fot the radios and the accelerometer
A case for the boards
A mount to attached the case to the boat.
what processes will be used?
Eectronics: Designed in Eagle starting from the Radio Hello board.
Modifed and then PNG's sent with fab modules to the Roland Modela. Stuffed with patience and time.
Case: Designed on Draftsight, and then sent to Epilog for laser cutting
Joint Cases: Designed on Inventor and then printed via Cura on the Ultimaker II
Mount: Designed on Open Scad and then printed via Cura on the Ultimaker II
what tasks need to be completed?
I need to finish with the design of the case and laser cut it. Also the joints as well.
The rest of materials are designed and already made. It's time for programming.
what questions need to be answered?
Are the radio board well done and can communicate each other?
Can they send data via SPI?
Can they use the data of an external accelerometer that is going to be connected to the radio board?
What's the distance than they can get?
Are they going to work on a boat while this is moving constantly?
How am I going to receive the data in my computer?
How am I going to transform this data into music?
what is the schedule?
Electronics (7 days)
Designing the boards: 1 day and a half.
Milling the 3 boards: Half a day using fab modules and a Roland Modela.
Stuffing the 3 boards: 3 days with items from the inventory. Hello Radio is a way more complicated than Hello world...
Making cables and connectors: Half a day
Programming:2 days
Mechanical parts (3 days)
Designing the case: Half day
Lasercut all the parts: Half day
Assemble the case: Half day
Designing the mount: Half day
Printing the parts: Half day
Printing the joints: Half day
how will it be evaluated?
Did you designed the electronics? +1.5 points
Did you milled and stuffed a difficult electronic board or just a simple one? +1.5 points
Did you milled an accelerometer that it also works? +1.5 points
Did you make the electronics work so they can communicate? +1.5 points
Is the data of the boards correctly sent to the computer? +1.5 points
