the parts for this project are as following
you will need (in picture)
1---- 100nf capasitor
1---- ln4007 diod
1---- 150ohm resistor **
4---- super bright white leds (i will be using some bright orange LEDs) *
solder
soldering iron
pliers
* this is to make the 4 led version... if you want the 2 leds you will need a 348 ohm resistor instead
** the value of the resistor will also very with the input Voltage, the type of LED you buy and the Diod...
my led has a Forward Voltage of 2V (the white ones are 3.5V or somthing like that) and a max of 20 miliAmpers and my diod of 1.1V and i think a max of 1amp
so if you would like to calculate the exact value for your components you will need this information..
In the images i leave you a formula to calculate the resistor depending on your components..
in this formula (in the image)
V--------- is the voltage you will use to power the led
Vfled---- is the forward voltage of your led
Vfd------- is the forward voltage of your diod
Imax---- is the maximum voltage that your circuit can take so that would be your LEDs operation current
nºleds-- is the number of leds you will be conecting(if the resistor gives a negative number you passed the limit of leds)
the circuit is very simple just a bunch of leds in series with a diod to protect from any reverse voltages and a capasitor to filtrer any large spikes that can burn out the leds (Cars have many) and a resistor to limit the current .. the capasitor is optional but i recomend it specialy if its going on a car...
in the image you can see the circuit for a 4 led light with all the calculations..
