I just pulled this out of a cattle car i bought. Still works any one know how I can make/ obtain something to power from the track DCC?
QSI sound board
- Thread starter Graham
- Start date
I'd be tempted to use one of these

Connect the module input to the track via a bridge rectifier and adjust the output voltage to 9V before connecting to the sound board

Widgets arrived and duly fitted. Works a charm many thanks for the help
. Still fascinated how they can make these widgets and sell them for pennies. Anyway bought 5 just in case I can think of another use 
Hm would those Widgets work for dropping down DCC Voltage to power Coach Lighting with suitable LED's?

Yes, but you still need a bridge rectifier..
Same with these..

(Blatant plug!).
with constant voltage on the rails, just use more LEDs in series, you will consume less power.
I use those "strip lighting" LEDs that come on a 3 meter roll, and they run at 12v DC... I put 2 strips in series (supposedly requiring 24v), but the 12v strips will work down to 9v... so a full wave bridge (half a buck or less) and 2 strips in series, and nice lighting for pennies, no extra electronics unless I want to put a filter cap on the output of the bridge rectifier.
Also, by "using" the voltage of the track, not wasting it in a dropping resistor, or converting it to a lower voltage, I use the least amount of the current on the rails.
Simpler, cheaper, less power... DCC makes an excellent "power supply" for lights on trains.
