@marath010 Good idea, are you thinking about shoes or a sleeves that goes into the while using the HA, then wires coming from the sleeves into a power source?
3D printing perhaps?
Somebody give me a PhD
Wait a second, potentially you could bypass the rechargeable batteries all together?
@marath010 Nah, I was thinking along 3d printing, you could use something like, Fusion 350 (it used to be free, not sure now, but worth checking if you want to go that route):
The only problem is you need to 3d scan the or make a mold of the HA, so you can create a shoe, then integrate the metal contact charging system into the shoe, then the rest should be easy.
I think it is a good idea, rest the practicality of it that is to be researched.
The argument is, if the system below was useful, then why not what the OP is trying to achieve?
I say, go for it and good luck.
Dont overthink it.
I really just plan to solder melt the charger case, snip some headset wires to make it longer and then hot glue it to blunt the rough edge.
Im not making a high end prototype.
I have programmed these type of aids for clients. You can’t charge and listen at the same time. What you can do, is buy a power pack battery and cable and charge your aids when you aren’t using them for like 15 or 30 mins.
