Chacha’s final Diamond heart

For my final project, I made a light that beats with my pulse. I call it diamond heart.

Link to my instructable: https://www.instructables.com/Diamond-Heart/

Material list:

  • 3d printing filament PLA red transparent
  • A white T-shirt
  • pulse sensor
  • a long USB-c cord
  • Arduino nano board

Diagram sketch:

On NANO:

Worked:

Coding:

// Pin Definitions

const int heartbeatPin = 2;  // Pin connected to heartbeat sensor signal

const int ledPin = 3;        // Pin connected to LED

void setup() {

  pinMode(heartbeatPin, INPUT);  // Set heartbeat pin as input

  pinMode(ledPin, OUTPUT);       // Set LED pin as output

}

void loop() {

  // Read the heartbeat sensor’s signal

  int heartbeat = digitalRead(heartbeatPin);

  if (heartbeat == HIGH) { // Heartbeat detected

    digitalWrite(ledPin, HIGH);  // Turn on the LED

  } else {

    digitalWrite(ledPin, LOW);   // Turn off the LED

  }

}

How it works on my pulse:

Put battery+Nano board in the diamond heart case:

3d printed them:

Final :

If I would do it again, I will:

  1. Set up 3d printing slicing data differently so the surface can be probably smoother/or thinking about more materials.
  2. Think about the target group and audience/ using scenarios.
  3. Probably have more LED so it can be brighter.

Chacha’s final proposal

Ideation

  • Pulse Monitoring LED Heart Lamp
  • I want to make an Arduino-based LED lamp that monitors heartbeats through a pulse sensor and flashes a heart-shaped LED lampshade at the heartbeat frequency.

Material list

  • Arduino Uno: 1
  • LED lamp (red or RGB): single LED or RGB LED
  • Pulse sensor: 1
  • Resistor: resistor of appropriate resistance value
  • Connection wire: several
  • 3D printing material: PLA translucent 3D printing material

Making process

  • Connect the output pin (S) of the pulse sensor to the A0 pin (analog input) of Arduino.
  • Connect the VCC and GND of the pulse sensor to the 5V and GND of Arduino respectively.
  • If using RGB LED, connect the red, green, and blue pins to digital pins 9, 10, and 11 respectively, and each pin is connected to GND through a resistor.
  • Circuit test: Use simple code to test whether the LED and pulse sensor are working properly.
  • Make a heart in the modeling software and reserve a wiring hole
  • Print a 2mm thick lampshade
  • Assemble

Chacha’s Halloween costume

Process:

The step one was a failure trying on make a 4 legs dog on sewing machine, that made me cry;(

So I made it out of my hand sew(a ugly and small version), so i got the shell finished then I did the soldering and ran the test on Gema⬇️

After I decided to just having the light for the eye part and put all light part inside the eye and sew the shell close (and it worked out), the light decided not to work;) ⬅️this is a trying not to cry again face

The only light worked was the light on Gema board…

So I finally I still took the pic of when the (ugly)dog skeleton with me

The pic with me:

ChaCha’s Halloween making plan and material list

Story:

Fictionally, Chacha will become a zombie that day but the only thing Chacha will remember is that she is still with her dog(a skeleton corgi lamp).

Material list:

black cotton fabric-the body part shell

stuffing-inside the shell

white stripe-the bones

chain-hanging

Hollow wooden stick-handle

2 LED lights-eyes

Battery+Battery case

Arduino Tech: blinking

Chacha’s Plush night light

  1. Material list
    – Linen fabric(2 colors)
    – Led lights(4)
    – Batteries(3)
    – Battery case
    – Wire + resistance
    – Ping Pong balls(4)
    – Stuffing
    – Needle + thread

  2. Working process
    – Testing fabric: how the lights coming out from linen

– Testing soldering: in order to solder 4 Led lights together with the battery case, I was trying soldering different kind of wires to the battery and turned out that the one we used for Arduino’s exercise were the best(and working!)because it has the one piece ends so makes the solder cleaner and easier.

3. Outcome

– So I got this ball shape, organic textured, casual and comfy plush night light⬇️

4. And Haosen wore it 🙂

Chacha’s Plush Night Light Proposal

Background

Recently found linen is a really cool material，I wore a lot in this summer and found it look comfy&casual&organic and feel comfy. Thinking of combining this material & organic style with a light sounds pretty interesting:)

Plus, I do need a lamp for my night stand now;) (I mean what kind of stupid apartment gives you ceiling lights, and there are 2 of them? It’s either too bright or too dark at night)

Sketches

Prototype/testing

⬇️ light affections w linen fabric(2 colors)

Target user/ Story

People who love organic lifestyle and organic shapes that needs a lamp for night stand.

Making plan/materials List

  1. Fabric:
    Linen & Cotton ➡️ Light cover/diffusing
  2. Metal:
    Copper/Iron wire (depends on the color and the hardness I want)➡️Giving some support to the structure for the light cover/diffusing
  3. E-parts:
    Led light light, Cords, Switch➡️Light functioning components
  4. Other supporting materials that might apply:
    A wooden tube, A wooden base, Glue, Screws➡️To make the structure shape of a lamp

Canon DS126251 camera teardown

ONE: Disassembling Process & Documenting process

Before & After:)

So it started with removing something that doesn’t need a screwdriver, here they are ⬇️

Lens, Memory card, A piece of rubber

Then I got 2 simple small screwdrivers tools and started trying disassemble the camera with them⬇️

The problem at first⬇️

1. Too hard to unscrew then I messed up the screws. 2. Didn’t find the hiding sneaky screws🥲🥲🤬

So should I just break it from now⬆️?

But I decided not to break them yet

So I opened the middle part FINALLY!

Then 7 hrs disassembling started…⬇️

Yay! keep messing up the screws and keep adding tools to this whole process.

Some progress⬇️

It was actually pretty satisfying when I saw I there were more and more parts coming off.

Then I decided to take a dinner break🤭🤫🤪⬇️

Kept going ⬇️

Was getting late ⬇️

Was me in the studio at 9:30pm, but it was almost there😎

Then finally! It was 10:24pm

Yea, nice to meet you in this way, Canon:)

TWO: Parts

1.Surfaces and screws

2. Front screen and front bottoms

3. viewfinder and lens connecting parts

3. Exterior and led screen penal on the top

4. Everything in the middle and chips
