How to make a instant water cooler at home || IndianRobotix

In todays video i am going to show you how

to make a instant water cooler at home.

For making this you need a peltier cooler module

I have a separate video how to make a peltier module

link given below. You need a plastic tiffin bow to hold

the cooling temperature also i am using aluminium food

packets to be a supportive product to hold the temperature.



After making this you can instantly cool down a glass

of water and drink.

experiments, hand made crafts, New Year crafts, presents, toys,

ROBOTs etc.

You will really like my channel as in here you can see how to make

things from cheap things or junks.

Thank you friends thanks for watching. Please subscribe to my channel and share with



your friends.If you like give thumbs up.

MEASUREMENT OF DIRECT CURRENT IN BATTERY USING ACS712 CURRENT SENSOR CIRCUIT

CODE ::::

void setup()

{

Serial.begin(9600);

}

void loop()

{

float average = 0; //SET initially average value or dc value of current to zero

for(int i = 0; i < 1000; i++)

{

        average = average + (.0264 * analogRead(A0) -13.51);

        delay(1);

        }







Serial.println("Direct Current Value = ");

Serial.print(average);

Serial.println(" mA");

Project- 2: How to make a USB light by using a unsupported USB cable.

PROJECT : 2

How to make a USB light by using a unsupported USB cable

           
       
               In here i describe how a USB light can make from simply 2 LED and a unsupported USB.
Just you have to cut the USB and select red and black wire and connect a LED to this. when you connect this USB to your PC or mobile charger or OTG cable then light is on.

From USB you get around 3 to 5 V and in red and black wire you get that so i just use that and lights on those LED.

Project-1:How to make a 9VDC source from 220 V AC system by using bridge rectifier circuit.

Project-1:

    How to make a 9VDC source from 220 V AC system by using bridge rectifier circuit. 

              A bridge rectifier is an arrangement of four or more diodes in a bridge circuit configuration which provides the same output polarity for either input polarity. It is used for converting an alternating current (AC) input into a direct current (DC) output. A bridge rectifier provides full-wave rectification from a two-wire AC input, therefore resulting in lower weight and cost.

     A bridge rectifier circuit given here,
                                                     

BRIDGE RECTIFIER

LM 7809 IC description means where input and where output you connect given in the figure below,

In this video i describe how one can make a 9 VDC source from our domestic 220 VAC source.I use basically a transformer,a bridge rectifier circuit and a voltage regulator.

PROJECT- 1

You can buy transformer from the side mention below,
