I lost the sound. 

Disconnected the speaker and re-binded the throttle, and the engine ran fine.

Re-connected the speaker and still no sound.





Push the 'stop' and 'light' buttons simultaneously,
and the sound came back on.
 
Must of hit them accidentally somewhere before hand,
without knowing it and had turned off the sound.

The photo shows how small the controller/throttle really is. 
Gotta be careful when pushing one of the buttons.

Headlight still does not come on. 
Used my multimeter, I'm getting like 2-4 millivolts. 
Should be getting more than that.

With the engine sitting at a stop there is a compressor sound,
and an occasional blowdown sound. 

When braking there are squeaking brake noises. 
Not the best sound quality, but still kinda neat.

Life and work have been getting in the way and slowing down progress.





Getting the engine put back together. 

Boiler is back on the frame along with a new cab (minus roof),
and a new headlight.

The speaker in the tender is taking up more room than I anticipated,
and making things kind of tight. 

Should have everything done in the next couple of days,
if I can keep everyone out of my way.

Hi Michael  :wave:



L :cool: :cool: KIN'   G :cool: :cool: D      :thumb:


I wonder what the sound is like through a regular Hi-Fi speaker ?  L:


The actual transducer & its implementation can vary massively.

The digital sound generated by these things is pretty standard.



:pimp:



Si.

Not bad, but not great. 
About average I would say. 
Still it's kind of neat to have sound.
 
But, I didn't really buy the Loco Genie for the sound,
but because it was small and fairly simple installation. 
Just needed to add battery for power.

I still see it as very affordable,
if you can find a Loco Genie at a discounted price. 
For the Genie plus battery I'm into it for about $55.

Hope to post some final photos real soon.

The battery and on-off switch is hidden under the oil bunker. 

The Loco Genie will continue to run as long as it has power. 

By installing a simple on-off switch, I don't have to disconnect the battery all the time.










Well, that's about it for installing the Loco Genie. 

Works well, and a fairly easy installation.

Now to run some trains.

Hi Michael  :wave:



As an 'audio guy' ...  :pimp:

... the first thing I'd do, out of curiosity ...  L:

... is to wire up the sound output, to some headphones and/or a 'regular' speaker.  :dt:

Just to check out, what it  REALLY  sounds like.  ???



The sound output on these should NEVER be connected to a Hi-Fi amp input directly ...  :f:  :td:

... but connecting the output to any 'regular' headphones or speaker is fine.  :)


Just for laughs, I'd try it through my DIY made 15" 'Eminence' Beta-15 !  :shocked: :shocked: :shocked: :shocked: :shocked:




The enclosure design makes ALL THE DIFFERENCE when it comes to sound quality.  :brill:


It is possible to find small speakers, used in laptop computers, quite cheaply.  :cool:

The enclosures are generally small & kinda flat, but make the most from a tiny speaker.


A styrene DIY mini enclosure is another experimental option.  L:

I gotta get me one o' these lil' babies & have a blast !  :pimp:



:moose:



Si.

Some other possible speaker wiring schematics, which could be used.  :brill:

:java: :P

The basic single 8 Ohm speaker, wired in series, for an 8 Ohm load.  L:





Two 8 Ohm speakers, wired in series, for a 16 Ohm load, would reduce the volume output ...  :f:

... unless of course, both the cone areas were larger & more efficient.  :thumb:





Four 8 Ohm speakers wired in series/parallel ...

... for a 'regular' 8 Ohm load.  :)

(typical 'Marshall' 4x12" cabinet, as used by 'Spinal Tap')





And NOT ^^ RECOMMENDED, two 8 Ohm speakers wired in parallel ...  :td:

... for a 4 Ohm load, which would probably OVERLOAD ! the amplifier !  :shocked:



:dt:

#7 is running just fine. 

Acceleration is slow (you can make adjustments to start up faster)
but I'm kind of liking it that way. 

By slowing things down it makes the layout seem larger,
and takes longer to get the job done.

Did find a few spots in the track work that #7 didn't care for.


I've got another Loco Genie that will go in the Athearn SW1500. 
Starting on a new cab now.
