Hey, all! I'm new here at instructables. I'm majoring in Electronic Engineering Technology in college at the moment. Anyways, I was reading through the (https://www.instructables.com/id/Build-a-Ski-Helmet-walkie-talkie-%22ACS%22/) Build a Ski Helmet Walkie-Talkie; and I have a couple of questions. I posted on the topic, however, no-one has posted on it in quite a while, so I figure I'd post here. Basically, I want to use this instructable to make an Airsoft headset (more than likely 2-way). Here was my comment: "I know it's been a while since there was a comment, but I have a few questions. My friends and I play airsoft. I thought'd it'd be pretty neat if we bump-up the realism in the game with helmet (in my case a mask) to helmet communication. Now for the questions: 1. I may not be getting this, but how do you sync up the walkie talkie and the Xbox Live headset? I skimmed over your instructions, but have yet to try it. 2. Is it possible to have helmet-to-helmet communication? As in 1 Xbox headset to another Xbox headset, not to a radio. I would really only want just two headsets (for now, at least). I'm not really expecting this part to be possible with this current set-up, but any information you can give will be extremely helpful. I'm currently majoring in Electronic Engineering Technology, so I have a slight idea of what I'm doing. I thought that this would not only be quite helpful and efficient, but also great practice for the field I'm going into. Thank you for your time, Darryn" Any help on this project (and answering my questions) would be greatly appreciated! Darryn.
