Adding mute to a Bluetooth headset

[Jared] often needs to be on conference calls for work during his motorcycle commute. He’s got a bluetooth headset that cancels noise but it didn’t have a mute feature. He cracked open the speaker and microphone portion of the apparatus but there wasn’t enough room for a switch. The base unit which houses the noise cancelling hardware had plenty of room. He added a single pole double throw (SPDT) switch to the positive wire from the microphone, allowing him to disconnect it as a mute function would. He mentions the need to seal the unit with silicone after the hack in order to keep out the elements. We might have opted for a weather-proof switch as well.
This simple hack makes a nice addition to any Bluetooth projects you’re working on.
