[FabNotes34]作业17：应用 | Week 17 - Applications & Implications

propose a final project
that integrates the range of units covered, answering:

what will it do?
who's done what beforehand?
what materials and components will be required?
where will they come from?
how much will it cost?
what parts and systems will be made?
what processes will be used?
what tasks need to be completed?
what questions need to be answered?
what is the schedule?
how will it be evaluated?

projects can be separate or joint, but need to show individual mastery
of the skills covered

where possible, you should make rather than buy the parts of your project

Final project proposal

My final project is making a theremin-like instrument.

what will it do?

You can play a song with your hand but without touching anything. It's like touchless instrument.

who's done what beforehand?

Many electronics and maker have made theremin. Gaudilab even made a opensource library Open.Theremin. I'd like to make a simple version. And also some simplier projects like this.

what materials and components will be required?

Hardware

ATTiny 45 chip
Ultrasonic sensor HC-SR04
AVRISPSMD
FTDI-SMD-HEADER
RES 10.0K OHM 1206 SMD
CAP CER 1UF 1206
Dupont Line

Software

Arduino IDE
New Ping Library for Arduino IDE
OpenFrameworks
Maximillian / ofxMaxim addon for OpenFrameworks

Housing

basswood
3D Printing PLA connection parts

where will they come from?

Local electronic vender
Taobao
wood suply
Inventory from our fablab

how much will it cost?

item	quantity	cost
Attiny 45	1	$ 2
HC-SR04	1	$ 1
AVRISPSMD	1	$ 1
FTDI-SMD-HEADER	1	$ 1
RES 10.0K OHM 1206 SMD	2	$ 0.1
CAP CER 1UF 1206	1	$ 0.1
Dupont Line	5	$ 0.1
basswood	2	$ 10
3D Printing PLA	1	$1
glue	1	$ 1
TOTAL		$ 17

what parts and systems will be made?

the circut
the program
the box

what processes will be used?
