Switch Activated
QR code to instructions
Project Description
This project modifies a commercially available bluetooth media remote to support switch activation. It involves soldering female audio jacks to the existing board buttons. The device is lightweight and can be connected to a wide range of mobile devices or computers allowing for access to media software such as Spotify and other music applications.
This device is helpful for users with physical disabilities who would like quickly play/pause music and navigate between tracks.
Skill level: Beginner to intermediate (soldering is required)

Using a craft knife,
Cut an opening over the corresponding button areas and thread the mono jack wire through the opening.
Prepare the mono jack wire

Using wire strippers,
Repeat the process for all 3 female mono jack wires.

Using the soldering iron and solder,
Apply a small amount of solder (tinning) to the tips of each wire and the identified legs on the PCB board from step #4.
💡If the solder does not attach properly to the legs of the PCB board, you may want to increase the heat of the soldering iron.
Solder the wire to the button legs

Touch the tip of the wire to the button leg and apply heat from the soldering iron to solder the two components together.
Repeat the process for each button to be adapted.

Using a hot glue gun,
Apply glue around each wire to prevent it from getting pulled out and disconnected during usage.
Alternative: mold and apply Suguru around each wire and allow time to cure and harden.

Troubleshooting
Switch press does not operate button during testing�- Confirm the correct button legs were soldered.�- Confirm wires are not touching each other or body of the button.�- Ensure the battery is inserted during testing process.�- Ensure the device is correctly paired.�- Remove and reply case cover in the event that wires shifted during this process.
Deliverables Checklist
Device Storage & Maintenance
Maintain the device away from liquids or moisture at all time.
Prevent pulling or strain on the mono jack wires.
The device will automatically enter sleep mode after 30 seconds of inactivity. Any button press will reactivate it.
