Introduction: DIY AA Battery Holder
The title pretty much sums up the project. Why make this? If money is tight and 3 to 5 days of shipping is unreasonable for a AA battery pack here's how to make one for a temporary power supply. I say temporary because my prototype sorted out on me the first time almost starting a fire and destroying a battery in the process.
======== WARNING WARNING WARNING========
This project can be very dangerous and may cause a fire if unsupervised. Always re-
move batteries when finished using the Altoids Battery Holder to prevent sorts and da-
mage to batteries. === CATION ===I am not responsible for burns,cuts or property

Now that's out of the way lets begin with the tutorial. The Pictures should be detailed enough to give you an idea on what to do. Notes will be scatter though out the tutorial to pictures that are vague in instruction. This is my first Instuctable so please feed back would nice.
You will need.( ͡° ͜ʖ ͡°)
- altoids box(any box)
- Hot glue(with hot glue gun)
- solder iron and solder
- cardboard or thick card stock paper
- 4 paperclips
- 4 Double A Batteries
- pen (drawing planning)
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Cardboard, Hot Glue, and Altoid Tin Box.
To prevent shorts(battery circuit making connection with the tin box) Use hot glue(recommend) to add slips of cardboard cut out to make the shape of the Altoids box.
I also used a pen to help mark which way the batteries need to be faces and help plan how the rest of the build would loosely workout.
Step 2: Creating Paperclip Briges
I'll be referring to this image a lot(Battery Holder Blueprint). Now we will move on to the circular coils made from paperclips.
Make 4x of the double sided circular coils using snips or wire cutters cut ONE of the double sided circular coils(this will be used for the positive and ground wires later on).
Step 3: Wires & Soldering.
Take the two circular paperclips coils that where just separated and use two wires about the same length(I used solid core wires). As the picture shows solder the wires to the circular paperclip coils solder one to positive and the other to the ground.
Step 4: Hot Glue, Paperclip Coils, Placing Batteries.
This is were the project gets difficult. After the first Positive wire and Paperclip coil is placed and hot glued in(make sure the hot glue does not disrupted the connect between the battery and paperclip coil). Place a double sided coil opposite of the positive coil and another double sided coil opposite of that double sided coil(repeat until you match the pic. and end with the ground wire and single coil). Do this while adding in hot glue and batteries(wait until the hot glue has cooled down).
Step 5: Stripping Wires, Drilling Holes(optional)
Taking the two wires strip the ends of both to reveal the copper(if you are not using solid core wire you may want to tin them to easily place them in pins or breadboards).
(Optional you can ignore this step if you don't have a dremel or drill )Now this should have been placed future up in the steps but if you have a drill or dremel you can drill a hole to feed the wires through and secure with hot glue.
Step 6: Finished Project!
I used a Arduino Uno and placed the positive wire in Vin pin with Ground to GND.
And there you go! All done. ( ͡° ͜ʖ ͡°)
