Sound in the Aristo slope back tender

16.8v if you *really* must, but do not go higher than that.. Battery packs (especially new ones) can be quite a bit higher than the 'published' figure when new.

Gotcha - thanks

Wouldn't want to do it any harm. The first one is going well in the blue and yellow dismal which, interestingly, is a metal body (nickel silver Worsley Works etched body).

I took a tip from someone else who said that they put the Rx in the corner of a metal cab - presumably the windows may help a bit - and it's fine :clap::clap:
 
Coming in late in the game. The crude, rude methods used on AC/DC radios to create a "throatier" sound were a simple capacitor across the speaker and/or an inductor in series with the speaker. Always works for me to fine tune sound on "tinny" sounding tenders that are cheap plastic or not sound insulated.

The problem with Bachmann's Annie sound is that they tried to do too much, and in their desire to add steam hiss, ended up with a sound that dragged on too long, and ran into the next chuff.

George Schreyer's modifications shorten the chuff by replacing one of the capacitors - very effectively. The second mod to add a second capacitor in parallel with another existing one adds a bit of bass.

Finally, if you encapsulate the speaker, you can get quite a reasonable, and louder chuff out of the Annie :nod::nod:

You do know George is/was a rocket scientist, right? Heckuva guy.

I had no idea - I have frequently returned to his documentation on G scale locos, in the 13 years that I have been playing with garden trains.

That probably explains the name of his railroad - the Geologically Improbable Railroad - I took him to be some sort of a scientist :clap::clap:

As for rockets, well, whatever floats yer boat :rofl::rofl:
 
I met him some time ago, he lived in Los Angeles, he worked for a large aerospace firm, believe he worked on the space shuttle. We made friends and went to one of the local G scale train shows, the big one in Ontario I believe.

I was talking to some guy, and from behind me, George interjected a comment, and very pertinent, and, well, just a damn smart thought. The guy turns around and looks at George and comments to me, who does that guy think he is, a rocket scientist? George said "yup" and informed the guy that George really WAS a rocket scientist! Was pretty funny.

I had the honor of having him over my house and running trains, and my web site was inspired by him and his web site.

Greg

p.s. in the US, being a "rocket scientist" equates to being very smart

Providing power is a choice down to the individual, use the existing 9V battery supply, or add a 7809 voltage regulator and tap the supply from the RC battery pack, remember a 7809 requires a minimum of 11 volts to function, or add a DC to DC converter and tap the RC battery pack to power the adapter board, less overhead required to operate it.

That's all looking very interesting - it just so happens that I've recently acquired a voltage regulator or two :wasntme:

John, do you have the circuit diagram for that - I might try to build one :p
