Now, I am here with a new Model of PIR Simple Motion Sensor Led Light!
The Previous Instructable had Portability Issues and a Resistor Problem.
In this Version i have made it more Compact and Easy to keep with a little improvement which i got from comment.
Kits would be soon available for Grabs.
Message me to Book one. Price would be Only 7$ + Shipping ( would be estimated according to country)

Step 1: Gather All the Parts
First of all List of Parts Required:
5) Screw Terminal (2 Pin)
6) 4 White Leds.
7) Long Male Header (3Pin)
Sorry.. forgot to click pictures of parts.
But you could search the part image on google ;)
Step 2: Circuit
I Slightly Modified it from my previous instructable.
Now it has 1k in between transistor and pir. by which it reduces the drop out voltage of transistor.
Step 3: PCB Eagle Board File.
Taking measurments of PIR Was a Lot difficult but the measurment tool in eagle cad, made my day.
It helped me take a good measurments and helped to find the middle of the board
See Picture how i figured out the size and where to place components.
Step 4: Toner Transfer , Etching , Drilling ....
If you don't know how to do this then Please see these steps in my previous Instructable Here.
Step 5: Let's Start Soldering - Solder Screw Terminal
Solder the Screw Terminal...
Step 6: Solder BC547 Transistor
Remember The Position.
Step 7: Solder 1K Resistor
Solder the Resistor...
Step 8: Solder the Leds
Now Solder Those Leds.
No Need to Drill holes for it.
Because these would be soldered directly to board.
Step 9: Now Solder the Header & Join the PIR
Now Solder The Header to the Board and then with the other header on the PIR.
Step 10: Finished!
We have made a Cool Looking Compact Motion sensor Light.
Now Power It ON with 12v Regulator.
Give it a warm up time of 20 sec.
Now it should light up leds when motion is sensed.
