Included is a URL to a web site that has a device used by the free-flight aircraft hobbyists to bring down their aircraft after a pre-set time delay. This type of unit is referred to in the FF world as a "DT" (De-Thermolizer). The DT (through a servo or other device) causes the horizontal stabilizer on the FF aircraft to flip to a vertical position which forces the a/c to begin a falling-leaf decent.

I contacted the builder, Ken Bauer, to see if he had a way to extend the time-base increment and maximum time-out. With a firmware change he can program the timer to count in increments other than 30 seconds. He suggests that he could change the timebase increment to 30 minutes for our application which would give us a maximum time-out period of 20 hours. If we would rather have a different time-out I'm sure he could make it whatever we wanted.
The stand-alone battery that powers the unit could be turned on with a switch operated by some kind of a reach-rod mechanism from the superstructure. After the time-out the unit can activate a micro servo which could release a float (emergency buoy) as a locating device or what ever the sub driver might have in mind.
I have a question in to Ken asking if the "10 second Count-Down to launch window" can be ignored. I don't see any purpose for it in our application. Once the maximum time-out has been programmed during assembly of the sub all I want to do is just turn on the battery to activate the device.
It only becomes worthwhile for Ken if we place an order for a minimum of 10 units at $30 each. I suggested to Ken that we each deal with him individually and when he has ten orders to then make the mods and start shipping units. I have asked him for the details on how to place an order.
I for one am very interested in acquiring one of these units for each sub I build. I will create a poll to get an idea of how many people are interested. Let me know what kind of maximum time-out numbers would be most advantageous. Ken would have to let us know what kind of increment timebase would support a particular time-out.
