Re: Protecting bus to feeder connections
Hi Greg:
An other option are "suit case" connectors, no stripping, already insulated, $0.05 each.
If you want to use shrink tubing, instead of a butt

Re: Protecting bus to feeder connections
I have a small layout with about 100 feeders and 6 power districts. I'm not accomplished at soldering. No way I could solder that many feeders working overhead under the table. I used suitcase

Protecting bus to feeder connections
I am new to DCC, although I have been accumulating 'stuff' for 20 years - HO scale, so I have lots of questions, most pretty basic. Since the bus to feeder connection is a 'T' and precludes the use

Aaron,
I actually did watch that video back when I was looking at computer power supplies. I think I did the classic assume move and made the assumption that a pre-built header wouldn't need or would

Re: Computer Power Supply and Turnout Problems
Wayne,
Try watching this video by Joe:https://www.youtube.com/watch?v=bkP3rgciy3M
It’s rather informative, he has a whole series on layout construction so there could be other video’s that

Re: Computer Power Supply and Turnout Problems
Puckdropper,
So the hard drive helped, the load caused the negative 12v to go from 9v to 11.3v.
If I recall right in some of the homemade power supply conversions they wire in a couple 10w ceramic

Puckdropper,
Great idea.. I have hundreds around my shop here. I'll grab one and test it.

Re: Computer Power Supply and Turnout Problems
Do you have a spare computer drive anywhere? For this test, you can even borrow one from a working system--you just need it for a few minutes. Just plug a drive in to one of the power cables and see

Hi Wayne,
There several ways to check it out. However, which is "better" depends n just how it has been implemented. Is it all in a nice case with just two wires for the output, or

Re: Computer Power Supply and Turnout Problems
Hi Wayne,
The problem may be that it is not providing power because there is not sufficient minimum draw on the 5 volt lines. Some power supplies for PC's require a minimum current

Re: DCC Bus distribution and snubbers question
Dale,
If the snubber fixed it, why then add the booster? Were you also facing a load problem (i.e. too many locos/lighted cars/accessories)?

Re: DCC Bus distribution and snubbers question
I'll answer that: It makes no difference. All copper wire is "oxygen free", because if there is too much oxygen, you can't draw it into wire as it is too brittle.
I regularly make

Re: DCC Bus distribution and snubbers question
Well, so far, no answer from Ross.
From others, an unknown scale 10 miles in length reports no problems, and an N scaler tells me to reduce my gauge and use OFHC copper, and I won't have

Re: DCC Bus distribution and snubbers question
The snubbers are only anectoatal solutions based on many factors. Mostly parasitic reactance from using too large of a bus wire over an extended distance. The best advice is to use the smaller gauge
