Introduction: Pocket Light
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.
