I tried probably 3 or 4 other designs before i did this one, and I've still got a few others id like to try, but this design worked pretty well.
The problem i had with my first designs was the wiring. I kept running the wiring on top of the board and covering it with silicone or metal strips but while snowboarding my feet would rip the wires off. So i finally decided to go ahead and try to fiberglass one of them
Step 1: Find a Cheap Board
What you need:
A Cheap snowbaord ( I picked one up for $30)
Fiberglass & Resin
Drill & Bits
Step 2: Drill and Router
Before you start marking and drilling holes you want to sand the old fiberglass resin off the snowboard, your not trying to sand everything off the board, just enough to get it rough, and down to the paper graphics below the fiberglass resin.
Choose how many LED's you would like to use and figure out your spacing for them. I drew a line one inch from the edge of the board and marked 1" centers for the LED's and ran 40 down each side. Once you have all your holes marked out you can go ahead and drill the holes for the LED's.
After drilling router the top of the board just enough to have the LED's sit under the surface level of the rest of the board. BE EXTREMELY CAREFUL TOWARDS THE END OF THE BOARD IT IS REALLY THIN.
also if you use led strips you don't have to router nearly as deep.
I also ran a lip for a headlight and battery box, but i don't really like the way it turned out so i would probably suggest against it. (of course it may have been because it was my first fiberglass project)
Step 3: Wiring the Board
I also made room for headlights and a battery box. My board runs on 4 LED's and ive been using them for about 2 seasons and I've only had to change the batteries once. (thats 6 hour days all season long)
Step 4: Fiberglass the Board
we want to cover the screw holes so we can still attach our bindings, what i did was coat some screws in grease so that they would screw right out when the resin dried.
Probably the easiest way to keep the resin actually on the board is to tape the edges of the board, and just start applying resin. If you decide to make the headlights you can use fiberglass cloth and run it from the edge of the headlight wood toward the middle of the snowboard.
Step 5: Paint
You'll also need to make a plate to cover the battery box and hold the switch. I went to home depot and bought roofing tin and cut it out to fit using tin snips.
