Jiaqi’s Doctor Strange Costume

  1. Name: Doctor Strange Costume

Why I did this?

Because I like this. I think it’s really COOL!

I think the essence of LED is movement, and the light effect produced by combining with different materials. And the size of the area is also important

I stuck my hand between the handle and the acrylic sheet, hiding wires and circuits and batteries in my sleeve. But there are no pockets in my costume, so I have no place to put my phone.

I learned that acrylic sheets need to be tested for sculpting. Where the wires can’t be soldered, I bend them into a hook shape and hook them together before soldering. The length of the wire and the relative position of each component need to be planed.

If I did it again, I wanted to make the acrylic cleaner, make the handles as transparent as possible, and leave room for battery replacement (because this time I taped the battery case completely to prevent my clothes from interfering).

3. Materials used:

2 12*12 inch acrylic sheet

4 inch bearing

1 m Neopixel RGB strip

Button

Gemma Circuit Board

3D printed handle (PETG)

Battery case and 3 # 7 batteries

Wire, welding wire, hot glue, rubber tube, super glue

4.Circuits and codes

5. Process

Doctor Strange’s magic circle

Doctor Strange can use the array as a shield, I think the picture is very representative.

————————————————————–

Arduino technique(s)

The LED belt is controlled by Arduino around the shield, and the color change and sequence of lighting are controlled by a button (imagined).

————————————————————–

Materials and parts you’re using

LED RGB light strip (have before)

Acrylic plate (bought 1/16 “12*18”)

Battery case (already)

Hand card slot (planned to 3D print)

Bearing (still looking)

The circuit may be so, the code is still uncertain

“Ghost alarm clock” Plush Night Light by Jiaqi

1.”Ghost alarm clock”

2. FOR WHAT

Suitable for reminding children to sleep at night.

Give it a punch and go to sleep at peace.

3. Description of materials and parts used

Two batteries, two LEDs, two 100Ω resistors, several wires

Cotton, cloth, etc…

4. Circuit diagram

5. Description of your journey through this project, for example:

In this project, I sewed the doll and soldered LEDs by myself, which was a great sense of accomplishment.

I don’t feel tired doing interesting things. Very interesting

My product is for some people who always breaks the alarm clock by accident.

Remind children of bedtime, you can fight ghosts to sleep at ease

I plan to use 10 LEDs and speakers

Fujifilm Instax 210 Instant Camera Black Teardown

What I teardown is the Fujifilm Instax 210 Instant Camera Black.

———————————From JIAQI GU———————————

INSTAX 210 Camera – With its rounded shape, easy-to-hold side grip, and fingertip controllable composite control panel, the instax 210 offers vivid, high-quality prints almost instantly. Its automatically-adjusting flash, high-resolution retracting lens and big clear viewfinder add up to unsurpassed performance.

Finally we get all the parts, most of which are made of plastic, supplemented by glass and metal. Manufacturing is mainly achieved by injection molding and molds.

[MB8998-3] Chips: 8-bit Proprietary Microcontroller

The MB89980 series is a line of the general-purpose, single-chip microcontrollers. In addition to a compact instruction set, the microcontrollers contain a variety of peripheral functions such as an LCD controller/driver, an A/D converter, timers, remote control transmission output, buzzer output, PWM timers, and external interrupts.

TWO POINTS:

  1. I really like the motor drive gear part. When I tore down it, I couldn’t help but feel the human intelligence, it was like a precision mechanical watch, very amazing. I think the designers use different gears to adjust the speed of the film rotation and control the roller to send the photo out, with just one motor and chip to achieve the whole work together.
  2. The other part is the telescopic part of the lens, which is realized by the semi-fixed rotation of the parts, which is very interesting. [At about 36 seconds]
