Let the Pics speak for themselves :D















cost ~50 bucks for each :)

5 mm LED's - 2 rupees

dot pcb - 10 rupees

soldering iron, solder , 100W resistors.

use 3 LED's in series + 100 ohm resistor !
 
nope , i think these are plain vanilla white LED's. anyone knows where to source the ultra bright ones ?
 
^^ buddy, are these worth the trouble? I remember reading your post in t-bhp about this, but there I think you were complaining about brightness being low IIRC.

BTW I was looking at the internals of an old car charger I had lying around. It has some SMPS chip inside (forgot the name) which gives a stable output voltage of 4.5V (regardless of input battery voltage), so maybe u can rip one out and use in your circuit to maintain constant brightness.

If u dont have a spare one, u can buy a car mobile charger (maybe 150 bucks or so) to get a stable voltage.

Also, if u r able to source the bright white LEDs from somewhere pls let me also know.
 
the low brightness was when i used the 3mm LED's. the 5 mm ones are quite bright :)

here's a pic i took while comparing them :)
 
yup, the 5mm ones are available everywhere :)

I got mine from vrinda electronics @ thakaraparamb

PS: nobody is curious /wants to do this ?
 
^Seems like nobody would actually want such LED powa inside the car. :P

And do check DealExtreme for those ultra-bright ones found in torches, flashes etc. :)
 
heh, but those are expensive. these cost a tenth of those :P

Check the number plate lights in action :D It gets better at night!
