For your viewing pleasure...

I've had this thing kicking around since about Christmas...  Working on Russ's HO stuff got me in the sound mood, so I finally up and finished it.  (That and a friendly "Where the Hell is my locomotive?" e mail from the client...)  Alas, the job ended up requiring two re-wirings, and a replacement tender due to some errant soldering, still, in the end, it turned out okay.  Anyway, here it is in living color...


Sounds pretty groovy, but man those chips suck up the watts.  I tried MUing it with another identical steamer, but the speed matching was so far off I finally gave up.

That's nice. Also, I really like that new section of the layout. Really nice stuff!

Okay dumb question time.  How are the sounds synchronized with the motions of the valve gear.  In the analog days there was a cam on one of the driver axles that interacted with a hickeydoo that mated with a whatchamacallit.  The faster the drivers turned the faster the cam rotated and the faster the sounds were produced.  But in the world of digital there is no hickeydoos or whatchamacallits.

There is a wire that can be attached to a cam if you are so inclined.  Otherwise, it just synchs to the voltage being applied to the motor.  I'm sure there's a CV that can adjust the rate.

But "CAM" survive! It can give a pulse each revolution to the CAM decoder input, then you've to set in the memory how many chuff you like each pulse.
Or... just program a couple of value in the decoder and leave the CAM in the drawer :)
Sometimes it's "good enough".

Yes, there is a CV that can adjust the chuff rate up and down.  It is pretty cool to play around with, but a cam is a much better solution.  I have never seen one in N scale though...

Good job!

It'd be nice if you could adjust the chuff for the cutoff too... someday, I'm sure.

Among the numerous reasons why I prefer to listen to music in the train room.  By the way Carl, thanks for that Steppenwolf disc!  Side one has some good old blues as well as the requisite "Born to be Wild!"

How did you increase the sound output? SND144 right? I mean that's almost as loud as a QSI or SoundTrax. I hooked a larger 8ohm speaker up, and turned all the volume sets up as loud as I could and it's just not loud enough....

I'd last about three minutes with that running, and then I'd have to leave the premises. Nice technology and all that, I'm sure, but it's like fingernails on a chalkboard for me.

Pretty cool!!!  Distance of viewing is going to cause some difference between sound and sight in the real world you just need to scale it down.

I nudged up the CV a tiny wee bit, can't recall which one it is... the master volume.  But I also confess, I cheated it up a bit more when I edited the video.  The actual noise coming from the tender is almost overwhelmed by the whir of the electric motor at full throttle.
