Do-it-yourself DCC accessory decodergreenspun.com : LUSENET : Wiring for DCC : One Thread
I'm planning to build a larger railway with DCC (Roco) digital controlling. For some time I've been searching for an economic solutio for digitally controlling turnouts, but I didn't succeed to find a simple schematic to build accessory decoders @ home. Could you advise me with such a schematic? Thank you, Takács Bence

Check out my Do It Yourself page.
At the very least, CVP sells a kit for a stationary decoder. A how to build it yourself was published in Model Railroader a few years ago. I think it contained the schematic.

The idea of a DIY accessory decoder sounds simple. Unfortunately if it works from DCC encoded signals, it must have some kind of microprocessor inside. That part is not so simple. Unless your are a computer programmer with all the tools, you will end up buying a pre-programmed processor to operate your home-made accessory decoder. It will be pre-programmed to suit someone else's circuit. You might as well throw in a couple more dollars/Euros and buy the whole thing. But check out MERG on the web.

I have designed my own Accessory decoder and details are posted at http://trains.bivalkar.com
the decoders go under the roadbed and is a simple circuit design. I have the micro code if you need.
