- Copper tape x 1:
Description
Convert an Apple AirTag to fit in a wallet and double its battery life. The card is just under 4 mm thick, making it half the thickness of a regular AirTag.
Materials:
- Apple AirTag
- Soldering iron and solder
- Copper tape
- Extra CR2032 Battery
- (Optional) Safety glasses and helping hand
Instructions:
- Teardown:
- Carefully follow a teardown guide, such as this one on iFixit: https://www.ifixit.com/News/50145/airtag-teardown-part-one-yeah-this-tracks
- During teardown, focus on removing the speaker's copper coil without damaging it. So it can be used as a speaker.
- Battery Connection:
- Important: Ensure both positive connectors are soldered together for proper functionality.
- Cut a small piece of wide copper tape and use it to connect the negative terminals of both batteries. Solder the negative wire from the AirTag to this copper tape connection.
- Cut a thin, longer piece of copper tape to connect the positive terminals. Solder the positive wire from the AirTag to this thin copper tape.
