TLDR: I finished integrating a Bose Tactical Headset with a Bluetooth Audio receiver for use when Powered Paragliding ... or maybe snowblowing too?
When powered paragliding, the motor noise can get quite uncomfortable. After flying around for an hour or so, I land with a significant ringing in my ears.
I decided to try earplugs, and that worked pretty well. I for some reason however have a really hard time putting earplugs in (the foam ones), and after a while, they start to hurt my ears too. Additionally, it is impossible to have a conversation with someone when you have the earplugs in. I know some people use earbuds and listen to music while they fly but I find earbuds uncomfortable as well, plus they don't block out that much of the noise.
I had a pair of Bose Aviation Headset Xs laying around that I looked into modifying, but they wouldn't even come close to fitting under my helmet - and I didn't feel that modifying my helmet was a very good idea for safety's sake.
So I found a pair of Bose TTH Mark 1's on eBay for $50. They are the designed to be worn in a military Humvee in combat and have a unique 'talk through circuit' that amplifies sounds that are below a certain decibel level (think footsteps, racking a gun slide, etc) while the ANR cancels out the louder sounds such as diesel engines, turbines, automatic gunfire, etc.
I had a great idea that I could modify the I/O signals on the Bose headset to integrate a Motorola S9 bluetooth headset that I had laying around. I did some investigating and found out the pinout for the Bose TTH - some of which involved reading through a military humvee intercom operator and repair manual that I found online, seriously! Once I knew the pinout, I simply had to dissect the S9 Bluetooth headset and connect the up the headset wires to the bluetooth output channels! Unfortunately, the S9 was harder to take apart then I anticipated and I kinda broke it. Kinda.
Fortunately I remembered I had a completely different bluetooth receiver that I had purchased from DealExtreme.com a few years earlier that was also just laying around. Seeing a pattern? I carefully took the new receiver apart, cannibalized a stereo audio plug, soldered the connections together and tested it out. It worked like a charm! Soldering on the Microphone connections was a bit tougher; damned micro electronics have such small solder pads! Eventually I got it all strapped together, cobbled on a 9V battery connection to power the ANR circuitry, shrinkwrapped all the electrical connections and buttoned the whole thing up. I had to get creative some some electrical tape to provide a bit of strain relief for the 'new cabling' but I think it turned out pretty well. I did my first test call with and everything worked.
Unfortunately, the Bose TTH doesn't quite fit beneath my snowboarding helmet so I'm working on getting an Ops-core FAST helmet - anyone, let me know if you have one you'd like to sell :)
Here are some things I'm asking for so far:
1. Reserve chute
2. New swing arms (to replace my J-Bars)
3. New carabiners for my makeshift kiting harness
4. Noise-cancelling (passive and active) helmet/headset with aux input
5. Subscription to Paramotor Magazine
