M&M’s in Light-Box


In this article I am posting three images for a M&M’s mug to use a Kodakporta400 and ilford film simulation with Fujifilm X-T30ii camera in hand. Also I am posting the outer or say back-stage shot for my Light-Box with LED lighting the subject.

First lit’s see the colored shot using the kodakporta400 film Simulations.

Camera settings: ISO 2000, f 4.5, Focal-Point 34, Shutter speed 1/125s.

Here i use the ilford film Simulations. The setting was: ISO 6400 , f 14 , Focal-Point 34 , Shutter speed 1/125s.

This is the Light-Box studio I am using with an out-source LED lights.

In this shot I just change the light position.

Nikon S9900 shot – 23



Subject: The West-Bay by Nikon S9900

In 2016 I bought Nikon Coolpix S9900, I have Nikon D90, and Nikon 7100 both are DX (crop sensor), but S9900 is my first Coolpix (point & shoot) camera from Nikon, I use to have Sony T100. [:. Read more about my cameras and lenses Here .:]

This Shot: In most of the days I am taking the Nikon S9900 camera with me in the car, just to use it and to have photos with it. This is a shot through the car window while driving to work using on hand to hold the camera, in the background we can see the Towers of the West-Bay area, and in the foreground is a Mosque; and I am waiting for a traffic lights to be Green. The original shot was in color and I change it to B/W and crope it before uploaded. I am using Nikon S9900.

Arduino: NOT-Gate Circuit

March 24, 2022 Leave a comment

Learning : Electronic NOT-Gate Circuit
Subject: To Build a NOT-Gate Circuit using BC547 Transistor

[NOTE:
W
e are working on Electronic Devices, Voltage, Resistors and other Electronic Parts that may Become HOT due to un-stable current or Wrong Wire Connections..
PLEASE BE CAUTIOUS AND TAKE SAFETY NEEDED PROCEDURES.]

In this Project we will use the BC547 Transistor to build a NOT-Gate circuit, so we will Not use the ADRUINO board.

What we Need

  • 1 2Pin Push-Button.
  • 1 LED
  • 3 Resistors.
  • 1 BC547 Transistor.
  • 1 BreadBoard. [I am using a small 5x7cm]
  • Some Jumper Wires.

Connections

  • Connect the BC547 BasePin to a Resistor Pin1, Then the Pin2 of the Transistor to the Push-Button Pin1.
  • Connect the Push-Button Pin2 to Another Transistor Pin1, Then the Pin2 of the Transistor to BC547 CollectorPin, AND to the Battery(+).
  • Connect the third Transistor Pin1 to BC547 CollectorPin, and the Pin2 of the transistor to LED(+) Pin.
  • Connect the BC547 EmitterPin to the LED(-) Pin by Jumper-wire.
  • Connect the LED(-) Pin to the Battery(-).
Here is the Circuit on the Breadboard

Run-Time
Since this is a NOT-Gare Circuit then once we connect the Power we can see the LED turns ON, Now if we Press the button and keep pressing, the circuit will be in connecting phase and the LED will tune Off.

Here is a GIF clip of Running Time.

Daily Sketch: A Dear Face

This is one of my colored sketch back to June 2021 at lockdown time. For Colored sketchbook I am not in Daily based sketch, but trying to keep challenging my self.

May other sketches here ..

LED Fade-Off from Prototype to Gadget

March 10, 2022 Leave a comment

Learning about : Circutes, Capasitor, Push-Button
Subject: LED Fade-off apply it on a PCB Board.

[NOTE:
W
e are working on Electronic Devices, Voltage, Resistors and other Electronic Parts that may Become HOT due to un-stable current or Wrong Wire Connections..
PLEASE BE CAUTIOUS AND TAKE SAFETY NEEDED PROCEDURES.]

In one of my previous Post [Read Here] I did some connection on a breadboard using BC547 and a Capacitor to make an LED Fade-off in 60sec after pushing a button. In this post we will convert that circuit a simpler circuit doing the same thing from a breadboard to a PCB to be as a Gadget.

What we Need: Here is a list of what we will use:

  • 1 LED (I will use a yellow one)
  • 1 PCB Board 5x7cm.
  • 1 1000uF 6.3v Capacitor.
  • 1 Resistor 300 ohm.
  • 1 2pin Push Button.
  • 1 CR2032 Lithium Cell 3V Battery.

Connection: All the connections will be on a 5x7cm PCB Board, I use a thin steel wire to create a strap to hold the Battery, and:

  • Connect the Negative (-) Battery to Pin1 of the Push Button.
  • Pin2 of the Push Button will be connected to the Negative (-) pin of the Capacitor.
  • Connect the 300ohm Resistor Between (+) Pin of the Capacitor and the (+) Pin of the LED.
  • The Negative(-) Pin of the LED will be connected to the Pin2 of the Push Button.


Here is all connections on a small breadboard.

Here I copy the circuit on a small 5x7cm PCB.

Back side Connections.

Finslly, I cut the PCB to a smaller size and Label it.

Now once we Push the Button the LED Turns On and Start Fading-Out. [you may need to give 5-10sec to charge the Capacitor before seeing the Fading Effect]
