Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: What Do You Need
you will need:
discharged 9V battery
2 pieces of wire
soldering iron + solder
Step 2: Taking the Pieces You Will Use
take the battery and gently prize it apart with the pliers, you will need only the top part with the connectors (it is usually made of plastic), at the bottom there are two metal strips going to the + and - connectors, you can take them away as they are not essential to this project... when you are done you will only have the plastic with the connectors. you can cut some of the plastic away if you want
Step 3: Soldering
you are ready to start the soldering, take two pieces of wire and solder them to the back side of the connectors
Step 4: Cover It With Shrink Tubing
I noticed that the best way to cover it is with a shrink tube, you will need a tube 2-3 centimeters longer (1 inch) than the connector. shrink it around the connector leaving some tube on both sides. cut the holes in the tube where the connectors are (the - connector must not have any tube around it as it has to go into the hole of the - connector on the battery, this is not important for the + connector)
Step 5: Info
i know that there may be other videos about this. if someone feels i stole his idea.... i did not.
this project is very basic becouse it is my first instructable, the next instructable will be: "how to make an IR nightvision camera" which i built some time ago
