Applications and Implications
This week's assignment, was to propose a final project that integrates the range of units covered
What will it do?
At the beginning I proposed an electro-mechanical acoustic panel system as my final project. After some time I got inspired by the different results I got from the weekly assignments, so now I decided to make a mechanical + electronic musical/noise machine, with control settings for being able to generate different sounding patterns.
Who's done what beforehand?
There's reuge really old mechanical music boxes and there's a company called animusic specialized in the 3D visualization of MIDI-based music, but their machines are only digital (3d models), however "Sisu Devices" built one of their designs for Intel (video), finally the is a Sweden band called "Wintergatan" that make their own music machines, I think they don’t use electronics.
What materials and components will be required?
For building the prototype I’ll need:
X1 15mm board of Plywood
X1 3mm layer of acrylic
X1 FR4  board 
          X30 Allen  socket M6 bolts
          X50  Hexagonal M6 nuts
          X50 M6  plain washers
          X6 608z  bearings
          X2 M6  threaded rod 
          X4 NEMA23  stepper motors
          X1 IC  Atmega 328p 
          X2 22pf  cap 
          X1  capacitor of 0.1 uF 
          X1 resistor  of 10k 
          X1 resistor  of 1k 
          X1 resistor  of 0 
X4 mini switches
X1 16 MHz  crystal
          leds
          Headers
Wiring  cables
          12v power  supply
Where will they come from?
Electronics from lab materials (with some exceptions)
Hardware from local vendors (Malvinas)
How much will it cost?
25 dollars for the acrylic
30 dollars for the plywood
5 dollars the steppers
All electronics less than 20 dollars
hardware (bolts) 5 dollars
9 dollars for the bearings
What parts and systems will be made?
All the structure will be made on plywood + acrylic, electronic boards will be also made
What processes will be used?
For the structure will use the shopbot for milling the plywood and the laser cuter for the acrylic, will also use the modela for the electronics.
What tasks need to be completed?
-3d model the machine
-took from the 3d model the cutting patterns
-design the electronic boards on eagle
-write the code
-mill the plywood
-laser cut the acrylic
-mill the electronic boards
-assemble all the parts
-upload the firmware
-test
What is the schedule?
I’ll start with the building proses after finishing with the mechanical/machine design assignment, because right now I’m really focused on that task, I’ll start by doing all 3d modeling, next all the electronics + programming and finally all the fabrication, I think I’ll complete all in 3 weeks.
How will it be evaluated?
First ill test that all the electronic inputs + outputs work, next test if the mechanism works right and finally test the interface with different users and compare the different results.
