Pocket Light




Introduction: Pocket Light

About: I am a student of BSCS but I'm interested in electronics that's why I would like to think about innovative ideas and try to build my ideas into reality and i also interested in making a robots. email id: degen…

Hello! friends

Welcome to my another "Rechargeable Pocket Light" project. In this project i'm gonna show you how to make your own pocket light with Bike's head light bulb's cover the name of the light is "CYT (chungyate lighting)".

So let's get started.

Step 1: Circuit Diagram

With the help of this diagram we should build our circuit for pocket light.

Step 2: Materials

You'll need

CYT (chungyate lighting) "Bike's head light cover"

Smd led with lens

Mini drill

3mm red led

1n4007 diode

2.2k ohms resistor

Female pin connector

Rechargeable 3.7 volt cell

On/off switch

Veroboard (dotted)

Step 3: Making Hole

Take your CYT light's cover and make a hole with your mini drill according to the lens size of smd and one hole on CYT light's bottle for on/off switch and other one is for female connector at the end of the bottle.

Step 4: Smd Fitting

Now take your smd led and fit into the cover.

Step 5: Circuit Making

Make your circuit according to the diagram and fit into the CYT light's bottle perfectly.

Step 6: Fitting

All parts fix in bottle very carefully

Step by step:-

1: put circuit at lower end of the bottle

2: rechargeable cell

3: SMD led cover on it

4: place the on/off switch on bottle and put some hot glue on it.

Now its ready to use.

Step 7: Finish

As you can see red led gives you a charging status. Now charge your own pocket light and than its ready to use.

It's easy to use and easy to pick because of its light weight.

    I think you are using 5V charger(Nokia). would it be fine?

    No LED cooling, no current limiter, LED will die soon.

    There's something wrong.

    The input voltage cannot be 3.5V, it must be at least 4.3V due to the 1N4007.

    Rechargeable cells need a complex function for charging, your plan works but the cell life will be far shorter than a cell with a normal charger.
