Fab Academy 2016

1. 1st concept

A puppet substitutes for me when I’m not in the fablab.
It can be an alarm and a clock. You can set alarms to remind appointments.
It cheers us constantly like "Do your best!” “Don’t be serious” ”Take it easy.”

Optional :
the face of the puppet looks like each persons face and it speaks in his voice.
dancing with music

Finally, I decided my final project. I made "s-eel clock".
It has three imput devices.

[INPUT] push button
[INPUT] reading WAV files from microSD card.
[INPUT] Real time clock for mesuaring time

And when I push the buttons / when it become the time I set up

[OUTPUT] speaker for playing WAV.file from micro SD card

===What's s-eel?===
S-eel is a mascot of fablab kyushu univ.β designed by Shinichiro Ito. It has "S" shape in English and olso has "乙" shape in Japanese Kanji. "乙" call "otsu" in japanese. Therefore, we call this "otsu-unagi".

2. PROCESS

2-1. Making boards

My project plan is here.
I made 5 boards : read_microSD/ audio amp / power_supply / push_switch and got RTC board from online electronics parts shop.

2-2. Connecting boards

2-3. Program

I wrote a program with Arduino IDE. I used three libraries : PCF2129AT / TMRpcm / SD.
Download : program.zip

        TMRpcm tmrpcm;

        int pH;
        int swA = 4; // push button pin number
        int swB = 5; 
        int swC = 6;                                                                                     

        void setup()
        {
            pinMode(swA, INPUT); // push button I/O setting 
            pinMode(swB, INPUT); 
            pinMode(swC, INPUT);

            tmrpcm.speakerPin = 9; // speaker 

            Serial.begin(9600);

            Wire.begin();
            rtc.init();

            Serial.println("PC2129AT Sample Program");

            dt.h = 13;　//   set starting time : hour,month,second
            dt.m = 8;           
            dt.s = 50;                 
            rtc.setDate(&dt);            
            rtc.setAlarm(&dt_alarm);

            pH = dt.h;

            if (!SD.begin(SD_ChipSelectPin)) { 
            Serial.println("SD fail"); 
            return;   
          }
        }

        void loop ()
        {
            rtc.getDate(&dt);    

                if(dt.h != pH && dt.h == 9){ 
                tmrpcm.play("9.wav");  
                }else if(dt.h != pH && dt.h == 10){

                }else if(dt.h != pH && dt.h == 13){

                tmrpcm.play("18.wav");
                }else if(dt.h != pH && dt.h == 19){ 
                tmrpcm.play("19.wav");
                }else if(dt.h != pH && dt.h == 20){ 
                tmrpcm.play("20.wav");
                }else if(dt.h != pH && dt.h == 21){ 
                tmrpcm.play("9.wav");
                }else if(dt.h != pH && dt.h == 22){ 
                tmrpcm.play("10.wav");
                }else if(dt.h != pH && dt.h == 22){ 
                tmrpcm.play("11.wav");
                }else if(dt.h != pH && dt.h == 22){ 
                tmrpcm.play("otsu_taiiku.wav");
                }else if(dt.h != pH && dt.h == 23){ 
                tmrpcm.play("otsu_taiiku.wav");
                }else if(dt.h != pH && dt.h == 24){ 
                tmrpcm.play("otsu_taiiku.wav");
                }

                if(digitalRead(swA) == HIGH){  
                tmrpcm.play("otsu.wav");
                }
                if(digitalRead(swB) == HIGH){
                tmrpcm.play("10.wav");
                }
                if(digitalRead(swC) == HIGH){
                tmrpcm.play("13.wav");
                }

                Serial.print("\t hour :");
                Serial.print(dt.h,DEC);
                Serial.print("\t minutes :");
                Serial.print(dt.m,DEC);
                Serial.print("\t second :");
                Serial.println(dt.s,DEC);
                delay(1000);

                pH = dt.h;
        }

I wrote this program on the main board. Finally, it worked!

2-4. Making S-eel body

A. Material
black felt ×1 / 100 yen shop
cotton ×1 / 100yen shop
white seal felt ×1 / 100 yen shop
Snap button ×3 / 100 yen shop
B. Machine / tool
Sewing hand tool
lasercutter
Sewing machine
Download : s-eel.ai
I lasercut body and eyes parts with trotec speedy300 80W.
In felt 1mm, laser cutter setting is power 30% speed 4.2%. In seal felt 1mm, power 30% speed 1%.
Then, I sewed left and right body with sewing machine.

2-5. Assemble

I inserted boards and speaker into the s-eel body with cotton. Then I finished!
