Cleaning out the storage closet at the office. We have way to many laptop power supplies laying around. Just about all are HP. They put out 19v dc and are sized from 90 watts to 240 for the largest. You pay for shipping and they are yours. I am powering my DCC with one and it has worked fine for three years. Just hate to throw them away and I dont want to deal w ebay on this type of stuff. I have 30 or so for sure and at least one more box to go through. Oh and if you need short cat 5 patch cables, I have a whole bucket of those as well. Here are some. Have another box with more with the current gen hollow round plug as well.

sorry, but electronics is not my area of strength.
thus a question: what kind of wattage is best for N Scale trains
i am totally clueless as to how much would be too much
thanks

Where can you get a conversion piece that lets you plug the round thingy on the computer end into a DCC system?

Yes, round thingy is a technical term in my electronics level.  :drool:

You clip the first lug off and are left with bare wire which then is inserted into the terminal on the dcc system. My Digitrax has screw connectors for this purpose. I am not sure about other brands.
