A company that can convert my foam tip ear piece transducers to custom ear pieces?

Just wanted folks to know that I've figured out the wiring schematics and have developed and tested prototypes for IMSA or NASCAR to Chatterbox adapter cables. They work great and it makes instructing or coaching so much better!
The parts are pretty pricey (damn those patents), but I can make and sell the cable for a lot less than an IMSA to NASCAR adapter which Racing Radios sells for seventy dollars a piece.
IMSA or NASCAR style female jack to Chatterbox 6-pin DIN adapter cables - $45 shipped. If you want one, send an email to dbbmwm3(at)yahoo(dot)com
This is my first post on Rennlist, but you can check out my profile on bimmerforums where I frequently post (http://forums.bimmerforums.com/forum....php?t=1316894). I'm a club racer with the BMW club and NASA (IP/GTS#3).

Denis, can you describe how these work? Do they use the NASCAR harness in the car or does this connector go from Chatterbox to helmet for the microphone in the helmet and my earplugs still plug into the helmet?

Happy to hear of the progress.
To be clear, I have IMSA earphones and mic- can these be interfaced with C-box DIN input?
I would intend to use the regular C-box mic/earpiece for my students.

This allows you to use your ear bud and built-in mic helmet 2-way radio kit when instructing in student cars vs having to use a Chatterbox mic/speaker boom that you slip under your helmet. I've found it much more convenient, more comfortable and the sound quality is a lot better too.
Hope that answers your question.

Yes, it works for your system. I just made an IMSA female to C-box DIN cable for a fellow BMW/NASA club racer and he's tested it out to work perfectly.

One more question, Denis. There are differences among earphones/microphones for race radio setups. The Chatterbox has one volume control. When used with two Chatterbox mic/speakers the gain between instructor and student is the same because the equipement is the same. Is there an adjustment on your connector to get the volume right between the different devices race radio on one side and Chatterbox mic/speaker on the other side?

To note - I made a cable for myself and then had a bunch of racer friends ask me to make a few for them. It's not a business that I want to get into by any means, but something simple to help out fellow instructor/racers.

Thanks to everyone who had a cable made. I received all the parts today, built and tested all the adapter cables and shipped them out. I have a few left if anyone still wants one.
p.s. Here's what the finished product looks like...

Hi folks. It looks like these adapters are pretty popular and I'm on the third set of building them. I'll keep making them if racers want them. And thanks to everyone who's gotten one and I hope you like them!

For folks interested in getting adapter cables, you can now contact the folks at Sync Speed who have a bunch of both NASCAR and IMSA cables available. http://www.syncspeedinc.com/racing_store.htm
