Diy Camera Battery Eliminator

     Capturing your projects in images can be tricky and battery exhausting. In this project you'll be able to utilize as much battery power as you need while taking those stationary inside shots! Without the tasks of changing the batteries.

To begin you'll need the following items:

 1. Digital Camera that requires 2 AA batteries
 2. 3volt DC battery Eliminator highly recommended (some battery eliminators have alternate voltage settings. I do not suggests using this type. If you use this type you may accidentally forget to switch the setting to 3volts for this project after using the eliminator for a previous  project. Voltage increased more than 3volts will damage the camera.

 3. 2 Paper clips
 4. Soldering iron and solder
 5. Heat shrink tubing
 6. Clear tape
 7. Needle nose pliers
 8. Dremel tool
 9. 1/4 Drill bit & drill
10. 2 AA Batteries

Using your dremel tool and drill cut away the positive end of the 2 AA batteries.
Remove and clean the inside contents of the batteries as well as the outside battery label.

If you accidentally cut off the negative side instead of the positive side
don't worry you'll just have to solder the top to the side as I have
provided in the photograph below.

Next, Using your dremel tool cut a rectangular slot in the side of both
batteries. This can be done by cutting into the battery and moving the cutting tool with a
side to side motion  rather than trying to cut out a rectangle by positioning your cutting tool
from 4 sides.


Next, using your needle nose pliers straighten out a paper clip and
bend it into a question mark configuration.


Next, insert the "?" configuration into the AA battery case with the curved side
exposed out of the rectangular slot you cut. Solder the unexposed end of the paperclip
to the inside of the battery case. The battery case really gets hot so you may want to mount it
or hold it lightly in a vice grip.


Next, Slide a piece of heat shrink tubing onto the end of the paperclip and
cut about 1 1/4 extra as shown. This tubing will totally conceal the paperclips.

Cut off the adapter ends of your 3volt battery eliminator, slide on your
heat shrink tubing and solder the eliminator wires to the paperclip ends.
Push the heat shrink tubing all the way up to the battery housing. Use a
lighter to shrink the tubing to the paper clips.


Use a polarity tester to determine which battery is positive and which
is negative, and label or color code them. I used a hole puncher and
colored markers to code them as shown in the illustration below.


Batteries are covered in a plastic blanket to identify the manufacturer and to prevent
the batteries from shortening out. To prevent this from happening use some scotch tape
to protect the batteries and limit the risk of shortening out the 3volt battery eliminator,
when inserting them into the camera.

Now that you have successfully completed this project your ready for operation.
Inside the battery compartment of your digital camera you'll see the exposed area
revealing the memory card. Remember not to insert the eliminators with the paperclip facing
the memory card. To prevent damage of this area always insert the eliminators with the paperclips configuration facing towards the front  of the camera away from the memory compartment.

(*Note the battery compartment that's next to the digital camera door is (+) positive and the
other is (-) negative.)
