Week20. Project development

assignment

develop a plan for dissemination of your final project
prepare a summary slide (presentation.png, 1920x1080)
and video clip (presentation.mp4, 1080p HTML5, < ~minute, < ~10 MB)
and put them in your root directory

What is the deadline? How much time do I have left?

- Final presentation : june 18th.
- deadline : june 22th. ->june 30th(80%)
- for the finish : about 2-days

What tasks have been completed?

Block Diagram for overview

brief progress
- prepare for lcd module pcb -> LCD Coding completion, I2C Slave routine for master control remain.
- main controller schematic design -> Version-0.1(june 25)
- housing frame cnc work -> Version-0.1(june 29)
* frame -> CNC cutting
* MP3 player bracket -> 3D priter
* Front and rear Cover -> Laser cutter
- prepare 90% of electronics components(maybe add more depends on realization)
* wall mount type Switches and harness making

Progress Steps

1. housing

2. PCB-I: I2C interfaced Text LCD Module

For the display, I was designed a pcb about functionally have 'contrast' and'brightness' potentiometers
And maybe after add I2C slave communication program for receive data to display

(For the detailed pcb design files refer to week12 )

3. PCB-II: Audio Selector(Main Control Station)

For the project, I want to make a control station using for other peripherals.
This is my designing station board.

4. mp3 module inner housing in 3D printing

5. Assembly

power on test

what tasks remain?

- control station pcb
- pcb assembly and electronics components assembly(for wiring type: harness and connector etc.)
- chassis design and making(lasercut) for all units fitting(this work after pcb and harnessing)
- assembly-electronics and housing parts
- programming(~july 2)
- testing(~ july 5)

How will I complete the remaining tasks in time?

-21th: pcb artworking
-22th: pcb assembly and electronics
-23th: housing and assembly:speaker and VU meter pannel laser cutting
-23th: coding and testing ->each unit functionally test and code check for operation.

What has worked?

- For basic lcd function to display and 'brightness' and 'contrast' are working and display characters on screen.
- power distribution circuits show correct voltage output.
- mcu identification is correct, upload arduino bootloader for audio selector

What hasn't?

- For this time I didn't have my own design for Bluetooth MP3 module and audio amp.

What questions still need to be resolved?

- At the beginning of academy , I want to learn vacuum tube circuit to configure analog audio amp But, I'm change the project goal in this cource, because of I didn't make sure for the circuit.
So, I'll try to do with make sure circuits.

What have you learned?

Basically, I have to learn about pcb process and make a board. This ia the most valuable.
And, all kind methods to make a product are needs to have a lot of knowledgis.
Maybe, after I'will try to do again for assignments that I needs.
