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?IMG_20170916_1448261_rewind.jpg IMG_20170916_1448172_rewind.jpg
 
Thanks widget ordered and I have some bridge rectifiers in my toit box. :nerd:

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 :nod:. 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?

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.
