Decoder for Uncoupler

[robteed]

I need to know if this decoder could be set up to supply 1 volt of
power to operate a DCC uncoupler. I'm looking for a very simple
& cheap decoder. I do not need to control a motor but motor control
might be what I need to use since I think I could set a maximum voltage in JMRI DecoderPro to 1 volt ( maybe even 1/2 volt ) I could get away without the added circuitry needed to protect from over current.
I am building the uncoupler described here. www.rr-cirkits.com/uncoupler.html
I have the video of my built uncoupler here
This seems like a great design for uncouplers mounted on locomotives but I am trying to design something to work with rolling stock. Any Ideas?

The motor decoder does not have any function outputs so will be no good for operating an uncoupler like this, but the high power function decoder on the other hand will be ideal.

The function decoder can be added to a loco or any other item of rolling stock, and the 3-output decoder will be able to operate the couplings at both ends independantly using different function buttons if required.

I see no point in using the complicated current limiting circuit suggested in the article, instead I would just use a resistor to drop the voltage, I suspect a 100R or 82R 2W resistor should be OK for the job, but you will best be having a play with it and see.

Thank you Paul.
