Step 7: Power it up, adding batteries
The reason why I used two AAAs is because I wanted a longer battery life than a single battery cell that might power a big watch. I also wanted something I could find and replace easily. And AA batteries simply take up too much space.
Take your negative/positive battery connector piece (hopefully one where the batteries are side by side and have no free space between) and place it standing up inside the wallet then close it. If it closes, go you! Your work is easier now. If not, dremel it down on the bottom or top until it will.
Take one of those plastic pieces you pliered off and cut it so that it does not come above the ledge of the backplate. Then glue it in at the top of the right section in the backplate.
Cut away the entire little wall that is the top part of the right section, it'll get in the way.
Glue the battery connector in with the positive in the right side and the negative (springy part) in the place where that little wall used to be. make sure not to get glue on the battery connection points and to leave a space about a millimeter wide between the right most wall and the positive end.
Take a negative end by itself and a single AAA battery. Place the negative end and place it against the horizontal wall that you left and then stick the battery in. If it's loose, use those plastic tabs to beef up the wall until your battery fits snugly. Do not try to make it so tight that it is nearly impossible to get the battery out! If you have any backing glue those to the wall.
Before you glue your negative piece in, determine if you are going to use the sound card or LEDs. If you are just going to use the emergency lighting, You'll need to solder a 3 inch wire to the back of this. If you want the game sounds, you'll need another wire that is 6 inches. If you're using both, strip them then twist them together and then solder them to the back. It'll be easier that way.
I'm just going to assume you know how to solder, so forgive me for not elaborating on how. Also this end is going to get very hot! Hold it with a pair of pliers if you must. Do not hold it with your bare hand!
Now that you have the wires soldered onto it, glue it in!
This is where you might should deviate from the pictures and follow the instructions to a tee. If you follow the instructions you'll have a little more space for your credit cards than I did.
Dremel away the rest of the wall separating the right side from the middle section now up until the section where there is a TINY horizontal nub, which comes before the horizontal wall that you left.
Take your two batteries, place one in the completed right side and place one in the place where the wall used to be. take your other battery and press the negative end against the spring gently. If you have enough space in front of that nub you left for the positive end to be glued in front of or behind the nub, you're good. If not dremel down the rest of that wall until you're even with the horizontal wall you left and then press your positive end against the battery gently. Mark the place behind it, super glue a plastic piece to the wall on the back of that line and against it. Then let the glue set.
Now before you glue the positive end in, you have to yet again determine if you're going to use both the LEDs and the game sounds. Respectively 3 inches and 6 inches. Do the same thing as before if you're using both.
(These lengths are not the exact lengths you will use, and will most likely need snipping to fit properly without excess. I give these wire lengths so that you have a little to 'play with.')
Now place your end in place without gluing it in. Make sure it does not touch the negative end or else you'll cause a short circuit. Make sure that spring or the battery can touch it. When you've determined the proper position, then glue it in. Now you've got your power source! Take out the batteries if they are in.
