longboard led project?
i have a very basic knowledge of LED's and such, i know how to wire them, but i still get a bit confused as to what power supply and stuff to use. Anyways, i'm wanting to do a project similar to this instructable "https://www.instructables.com/id/DIY-skateboard-longboard-riser-lights-angled-riser/?ALLSTEPS" except that i want to have about maybe 10-12 led's on the bottom of the longboard pointing down (flush against the bottom) kinda like cars with the neon lights underneath...so my question is, what do you guys suggest i use as a power supply and where should i put it on the longboard so that it doesn't get destroyed while riding?, can i just parallel all of the led's or is this unwise? also, do i use 1 resister for the whole thing? or in between every parallel? like i said, obviously i'm not very knowledgeable about led's yet...i'm getting there though lol.
