Just hoping you can help with designing a circuit diagram and some specs. I am doing a craft project that requires some LED's to illuminate certain areas.
The project will have about 150 LED's, connected in groups of 2,3 and 4. Each group will have it's own switch so different sections can be illuminated.
The LED's have the following specs
DC forward voltage : VF (IF =20mA)
3.2V-3.4V Typ, 3.8VMax
DC reverse current : IR (VR =5V)
Intensity luminous : Iv (IF =20mA)
BC08 : 350-500mcd
Wavelength : Wp (IF =20mA)
What I was hoping for is if you could possibly provide instructions on how to connect the LED together, with any other components that may be required, and also how to connect them to the power supply, and what voltage and amperage the power supply should have

With the explanation of nik you can solve the problem. All you need is a multimeter to measure the consumption of one LED an then you can determine the value of resistors and power of battery. Here is an electric circuit for you to figure the hole connection needed. It is advisable to divide the circuit in blocks in order lo achieve better performance. If one led became short circuit, only the segment where is located will be off. The requirements of power for resistors will be easier too. You can even divide in bore blocks, depending on the power of LEDs.
I believe in most cars you have to drop the tranny pan to get to the filter. It is not hard to do but it can make a mess if your not ready for it. Make sure to get a replacement gasket when you get your filter and most auto part stores will have a diagram for you. The bolts on the pan will require to be torqued to a spec most stores can help you with that. Good luck.
The main fuse block on these vehicles is located on the left side of
the dash, behind an access panel. These is also a Power Distribution
Center (PDC) which can be found under the hood. Each fuse block
uses miniature fuses which are designed for increased circuit protection
and greater reliability. The compact fuse is a blade terminal design
which allows easy pull-out/push-in removal and replacement.
