Zai’s Digital Bulletin Board

Its been 5 months and 5 days since I’ve joined SVA and its a bummer that I still don’t know what most floors above or below me organize on the daily. The poster-bombing usually works as a trigger for to take my phone out to for a picture, But then 5 pictures later, I would never remember it again.

I’ve always been intriged by the concept of ‘waiting and time’ and how its degrees affect thought. For example : ‘I’m waiting for a train’ makes me think about 198838203 different things but as soon as I know my train is a little late, its one single unified thought about ‘why this train is late’.

Basically, ‘the time you spend waiting’ and how does one compute ‘waiting for something’ really thrills me.

Therefore, the digital bulletin board (TODAY) tells you what’s happening today for the 30 seconds you wait in a lift. It’s designed for Informed delight.

Now imagine you get into a lift with a child and he/she presses all the buttons… well … hold onto those intrusive thoughts cause TODAY, TODAY can keep you company.

Materials Used :

  • Monochrome OLED 0.96″ 128×64 OLED Graphic Display with STEMMA QT
  • Rotary switch
  • Adafruit Metroboard or compatible microcontroller
  • Jumper wires
  • Breadboard
  • Power supply (USB cable or batteries)
  • Enclosure : Acryllic sheets, Nuts & Bolts, Repurposed Dial

Instructables Tutorial Link


Connect the components on the breadboard as follows:

OLED Display

  • GND goes to ground
  • Vin goes to 5V 
  • Data to I2C SDA (on the Metroboard, this is A4)
  • Clk to I2C SCL (on the Metroboard, this is A5)
  • RST to digital 4
  • Connect the rotary switch to the appropriate pins on the Metroboard/ Arduino Uno. Typically, these are digital input pins.
  • Check the Serial Monitor to identify active switch positions

Error battles and the serial monitor


Forms took shape!


  • Would like to work more on the enclosure a lot more
  • A BIGGER display will be more effective (for sure)
  • I also intend on scaling this display towards other spaces perhaps, public spaces, residential apartments, schools, parks etc. Contextual data displayed for each of these spaces

Jinny ’s Final work progress☯️

I will continue with my Cyber Buddhist niche

I drew my storyboard in more detail

(It could be making a shrine and putting a screen in it, or it could be using a TV)

Cyber Buddhist niche style design:

I drew a design of a Buddha statue that will be projected onto the screen

I drew a printed Incantation paper:

(I will choose whether the charm is black or white based on the print effect of the printer)

prototype and circuit:

#include “HPD482.h” // Printer header file

#include “picture.h” // Image data to be printed

HPD482 printer = HPD482(); // Instantiate the printer module

void setup() {
pinMode(13, OUTPUT); // LED

// Printing starts here *//
printer.Print_SetDeep(8); // Set print color depth (used to modify print color depth, not necessary to set every time, already in the initialization, this line can be omitted)
printer.Print_Lines(5, 2); // Print 5 dashed lines with a spacing of 2mm
printer.Motor_Run(24, 0); // Rotate the stepper motor by 24/8=3mm for paper feed

printer.Print_Img2Lcd(0, (u8)Image, 1); // Print the image at coordinates 0 printer.Print_Img2Lcd(20, (u8)Image, 1); // Print the image at coordinates 20
printer.Print_Img2Lcd(44, (u8)Image, 1); // Print the image at coordinates 44 (the part exceeding the print range will be cropped) //* Printing ends //

void loop() {
if (digitalWrite(13) == 1) {
printer.Print_Img2Lcd(44, (u8*)Image, 1); // Print the image at coordinates 44 (the part exceeding the print range will be cropped)

Jinny’s Halloween Final Idea 🎃

Final idea:


Carton board

Transparent black plastic sheet

White and Black paint

LED light strip

  • Outer diameter: 44.5mm / 1.8″;
  • Inner diameter: 31.7mm / 1.2″

(Lamp strip to be used:


battery box

Complete suit

Production progress:

1.Cut the side of the monitoring head out of the cardboard

2.Make bottom surface

3.Make the side facing forward

4.Make the slot for the head

5.Making the top cover

6.Raise the interior of the top cover+Fixed top cover

7.try on

LED design scheme

LED light circle emits red light and then white light-Simulate the lighting effect monitored by surveillance cameras

Effect demonstration

Fading in and out of color


I had a lot of fun with the RGB LED this week. Instead of using a pingpong ball to diffuse it I used a flexible plastic material and was able to film the subtle differences in color through my phone’s camera by placing the plastic directly on the lens of the camera. I played some Amadou & Mariam in the background for rhythm:


In the second exercise for this week it was hard to get super creative, but I was able to change the rate of fade. Here is a faster fade than the original with the delay at 5:
