Hey guys, I'm super new to Arduino stuff but I thought Flutter would be a good start. I'd like to, for my first project, cut the cord on one of my headsets and use 2 Flutter boards as wireless USB points. Ultimately, I'd like to hide one of the boards inside the ear cuff of my circumaural headset along with a couple of cell phone batteries while the other board remains plugged in to a computer. I'm hoping this project will be as easy as identifying the leads on the headset and feeding them to the USB sockets on the board. Anyone think this isn't possible? Any expertise to be shared?

You couldn't just use this as a wireless USB hub, there probably isn't enough bandwidth and the way the code works it's more work than you should have to do for just voice. IIRC Taylor mentioned about voice being somewhat doable though I forget exactly where. You probably could make a wireless voice headset using a microphone but an Arduino board seems a bit overkill if it's just for voice to be honest.

ps- is this out of necessity or just to mess with the flutter board and get experience? I guess that'd be the main factor if it's worth doing or not the way you explained

Thanks fo the reply! To answer your question: I'm doing this to learn about using boards and chips. The reason I've chosen this project in particular is that I've gutted a cheap logitech headset and installed its internals into a more comfortable housing for a wireless headset I bought broken on Ebay. I could keep running it with the cord, but I'd really love to share my DIY Cheap Wirelsss Headset on a few DIY reddit boards. Do you think if I were to focus on hooking up a mic and speakers rather than try to make a wireless usb hub that I could achieve the same effects?

PS- Don't you love how much better cheap logitech headsets are than a lot of high end "gaming" headsets? That's another reason I'm doing this: I spent $100+ on a set of Skullcandies and their mic always makes me barely audible, but my $10 logitechs have never had a problem except their comfort is lacking.

Yep would likley be much easier to use just the mic and speaker from that, the receiver Flutter would do all the USB Interfacing. Would probably fit better anyways

Chiming in here. Audio is something a lot of our customers are interested in, and I already have one friend working on using Flutter for video. Though I don't have any target date for when I could contribute to some Flutter audio code, I have a feeling one of the backers will get it going pretty quickly. And I've actually ordered a microphone and amplifier board so I have a chance of doing audio at some point. I'd love to make a Flutter walkie-talkie demo so anyone can quickly bring up audio with Flutter. I've got a Logitech headset with only about 30ft range, so even in my tiny apartment it can't reach the kitchen from my computer in the office! I'm hoping I will get the time to upgrade it to Flutter in the not too distant future.

That said, you won't use the USB here. Flutter can only be a USB device, not a host. However, you can hook the microphone and speaker amplifier directly up to Flutter's input and output header. I don't have a tutorial for that yet, but if you look around for using an Arduino with speakers and a microphone, there should probably be some good information. Flutter is pretty much the same as any other Arduino, though it's much faster than most Arduino boards so it can do some nice stuff. It also runs at 3.3 volts not 5 volts, so some interface boards may not work with Flutter without additional circuitry.

Should be a good project though! smile

Thanks for the additional input, I'm still learning a lot about Arduino, so any tutorials now or in the future would be stellar. As soon as I figure out how to proceed I'll post pics of the housing and equipment I am using.
