I believe the guys at Olson-Engineering are closed down for vacation.

I think I can answer some of these questions. I have a functional but bare circuit (no housing), but I believe the finished product includes a custom case which houses the circuit and the Recorder2. I do not know if the unit will come with a switch pre-wired. The unit I have does, but I will be changing it to a different type of switch, which will be very easy to do.
The circuit works exactly as Ex-Navy described. Connect power at one end and the Recorder2 at the other. Flip the switch. The recorder powers on and starts recording. There is an approximate 7-second delay between when the pressing of the button and the commencement of recording (by the way, this is faster than manually turning on the Neuros and pressing the record button on the wireless remote).
The circuit I have also has a 5v regulator wired to it. 12 volts are fed to the (small) 5v regulator, and the regulator then feeds 5v to the circuit. Power to the regulator comes from my 12v car battery. I also branch off of these leads (the wires between the 12v battery and the regulator) to feed two 12v bullet cameras. I branch off of the other leads (the 5v wires between the regulator and the one-touch record circuit) to power two Recorder2 units.
I've run some basic tests and have had very good results. Stay tuned to these forums, and look for a detailed write-up elsewhere soon.
2 cameras
2 Neuros Recorder2
1 Olson-Engineering cirucit
Endless opportunities.

Don't want to say too much as Ex-Navy can do a much better job answering your questions. Just wanted to give everyone a heads-up that if replies seem slow from Ex-Navy and the guys at Olson, it is because they are on vacation for a couple of weeks. I can confirm that the product works, it is simple to use, and one circuit can trigger (at least) two Neuros Recorder2 units.
