Easy-build DCC decoder tester - check your digital chips AND test for realistic loco LED brightness

This easy-to-build test rig is perfect to see if your DCC chips are working, but my main reason for making it was to try out resistor/LED combinations to get a more realistic brightness for my loco lights. There is a little bit of basic soldering required, but the prototyping breadboard makes it straightforward to test various options.

Excellent

Thanks. Hope you found it useful.

When you plug in the cable from master if the decoder is other than #3 will it show the one on the decoder, say 6 etc. That is without using the keypad on master.

Yes. The decoder behaves exactly the same as if it were in a loco.

Do you have web address?

I have a very basic website: paterpracticus.com/ - eventually I plan to add more support for more videos, but it is a start.
