Birth of the Blue Missile

Sorry if all this WWW is boring, but considering I originally thought all the electrical stuff would take the better part of a year to fab, its going along well.
I believe this is the final built from scratch module. It interfaces the sound system and the PTT functions with the helmet intercom and 10 or 11 meter (CB) radio.
The helmet intercom has a VOX switch for the mic so that it acts like your cell phone, when you talk it transmits otherwise its receiving. But the two way radio uses a manual switch for that function. Hence the "Push To Talk" function at the steering wheel. I also use that function to mute the tunes while talking. The module also converts the center dash speaker from being used by the CD player to be used by the two way radio whenever that radio is powered up. The final thing I needed to accomplish was to transfer the vol/on-off knobs and the headset input jacks from the tiny circuit board to the front panel of the center console.
