I have a box nearly Full of 1/4 watt resistors... but I'd feel better using  1/2 watt in a simple circuit.  (

All tutorials I find handle the calculations of resistance as resistors are combined.  Fine... series is additive,   parallel is inverse average... but watts???  I'd think it's distributed over parallel resistors, and want confirmation before I fry things.  How small can my parts be before they don't perform?

I am considering replacing my DCC system on my layout.  And I thought I read someplace about a new system that supported various companies throttle bus systems.  Such as Digitrax, Lenz, And NCE as well as it’s open system.  But after looking through here and doing a couple searches I am not seeing anything,

Am I just missing it or was it a dream?  

Either way I am still considering a replacement system.

I connected my JMRI through NCE USB to NCE Powercab. 

I'm thinking of making the switch from DC to DCC for my 3' x 6' N scale layout.  I don't anticipate running more than 3 or 4 locos at a time, and I expect to be the only operator.  Couple of questions:

1.  Is there any advantage or disadvantage over competing brands of DCC equipment?  NCE vs MRC vs Digitrax?  Pricewise they all seem about the same for their entry level systems, any benefits to one brand vs another?  There are no model clubs or other layouts near me to visit, so I'm having to rely on the kindness of strangers.
