Cut out the screw holes from two opposite corners so the board and battery pack will fit in.
Drill holes in the sides of the box that line up with the jacks, switches, and adjustment wheel on the board.
Drill a hole in the top lined up with the light so you can tell when it is on.
Take the foam tape and put it on the bottom of the board and battery pack and stick them into the plastic box lining up with the holes.
Cut out a notch for the two sets of wires (motor and audio in wires) in the box.
Put the lid on and put the two screws in the corners.
If you made it the same as mine, it should look like this completed
Setting up the Virtual Boy
You must first pull the Virtual Boy apart enough so you can get to the speakers (see instructions on other page).
(Basically what you will be doing is adding another headphone jack, but this one won't turn off the speakers).
Then drill a hole in the bottom of the VB for the 1/8" headphone jack to screw into and put it in (make sure it won't interfere with the insides of the VB).
Solder a wire to the positive and negative of each speaker (4 wires total) (make sure they are long enough to reach the jack) (negative is the striped cable - I think)
Connect the 2 negative wires together and solder them both to the negative terminal of the headphone jack
Solder one of the other wires to one of the positive terminals on the headphone jack, and the other to the other positive.
Screw the VB back together and plug the box into the new jack.
Plug in the box and turn it on, make sure the switches are set where you want them and try it out.
If you don't get vibration, try headphones in the headphone jack on the box. If you don't have sound, you may have to hook up the negative of the battery to the negative of the audio in plug. (not sure why, but that's what I had to do, must have lost connection somewhere). If you do get sound but no vibration, check your connection to your motor from the board.
