This will be my first project but it will be really useful for me (and others). It does need a short explanation to describe what I need a solution for.
To assist with my poor hearing I have bluetooth hearing aids. I also own a neck-worn microphone that I can ask people to wear which sends a signal (not sure this is bluetooth) directly to my aids. (Both my aids and the mike are made by Phonak.)
I am a volunteer at a charity and often interview people in an office and my mike can make all the difference in hearing/understanding what people tell me.
However, this means that they agree to wear my mike and at the end of the interview it is all too easy to forget to ask them to take the mike off. As it cost approx£200 I am looking for something which will warn me when the interview is over so I can retrieve the mike. (Not all my 'clients' are totally trustworthy!)
Maybe something that makes use of the signal sent by the mike? A movement of more than a few metres causes an alarm? I will appreciate any help at this stage. Anything!
Low tech solution: just tether the microphone to the interview desk (or to some fairly large/heavy/conspicuous object if it needs to be moved around)
Higher tech: fit something like an AirTag or Tile to the mic.
That would be worth investigating - first you'd need to find out what, exactly, that signal is!
Thanks awneil,
I have thought about the tethering answer but have been looking for a 'project' to occupy me. Just making something that I don't actually need is no substitute for something I do need!
Thanks for your thoughts.
Contact the manufacturer and explain what your problem is and can they give you the information you need. You need to let them know how you plan on accomplishing this. Ie bluetooth, etc.
You could make a device that scans for bluetooth devices and sets off an alarm whenever your particular device is no longer in range.
Or you could use a laptop to do this.
OP wasn't sure that the microphone does actually use Bluetooth.
Scanning for Bluetooth devices usually works on Advertising - so not while the microphone is connected (if it is BT).
@rogo99 don't your hearing aids give an indication when the microphone goes out of range?
Great idea. I have done that now.

That is sounding like what I am wanting to do. As someone else has suggested I first need to find out what signal the mike is sending out - it may not be bluetooth.
Cheers,
Roger
When mike goes out of range I do get a change in my hearing aids. Unfortunately by then, though they could be out of the building!

Well, my Phonak aids connect to my phone using Bluetooth so I think you can assume it is. Phonak do a table microphone
...which is the other approach, rather than having something that the person you are talking to has to wear as well. Since mobile phones contain a microphone, which generally can be used for "loudspeaking telephony" so are quite sensitive; and Bluetooth, an app that just relays sound from the mic to the headphone connection ought to be possible. Then you would put the phone on the desk instead.
Actually quite a few of these on the Play store. I tried one and there was a horrible delay, others may be better.
