complicated resolution, surely?
I have sound on my turntable.
The loco itself.
Have you found a sound file of a turntable to super-impose on the loco sound?
I'm going to do it using a sound decoder fitted to the turntable decoder socket with shed and turntable sounds simmering away on it.
Video when finished, probably a couple of months, so don't hold your breath.

If you wish to get some authentic turntable sounds, with proper atmosphere [not preservation scene]  , watch ''Train of Events'' starring jack Warner [Doxon of Dick Green], it's an Ealing Studios film, available if nowhere else on Amazon, mind a clip may be on Youtube.
A few clips follow, the last one is best. for our purposes.

but this is the one, l reckon can be manipulated for what we want.
Any good sound editors?

That last clip is brilliant.  The noise sounds like a reciprocating steam engine, which makes sense, so I guess it might be possible to even use an existing locomotive file anyway if you could find one of a suitable cylinder and valve arrangement.

Both PCB + Spkrs have adjustable volume Simmering steam engine sound plus adjustable chuff speeds.  The left hand one is a kit, at around £6, dependant upon supplier [unless you go to some con artist on EBay, at £25!!].  Sounds are adjustable by the red handles.  At minimum chuff adjustment it still produces soft chuffs at just over 1 per second.  I will have to see if that matters, at the weekend.  Of course it has to be built, but I really enjoyed doing that and I'm quite pleased with the result. 

The right hand one is bought as is, at £17, including post and packing.  It has adjustable simmer sound [similar to the other one] but the chuff speeds are controlled by whatever voltage is received along the 2 green wires - normally from track rail pick-ups on whatever rolling stock it is attached to.  The response to voltage level for the chuffs is adjustable and {unlike the first one} starts at zero chuffs.

I used the Peco polarity change system as it is very simple and provided.  So when my "sound" locos arrive at the TT Bridge, they provide such suitable sounds as they contain.  They continue to do so as the TT Bridge rotates, until the polarity change-over gap, after which they continue as before.  The gap is roughly at the quarter way {90deg, 270deg} stages, at which point the loco should definitely not be chuffing, but simmering at some level.  So; all I need is an adjustable level of, "fill-in", Simmer around the 90deg and 270deg area of the rotating TT.  Large sound files of yards, shed or TT will not, therefore, be required, nor will it require a Function control added.  {NB. I may buy a separate sound unit with some local sounds to play with, but that's for another day.}  The chosen one of the two available units will be attached under the "recently, religiously converted" Well Grid and will Simmer to cover the gap in Loco Simmer.  

The observant will have noticed that the PCB Simmer would not be required at any time other than around the TT polarity change point power break.  Power for the PCB will be passed through 2 x DCC Concepts Pick-up contacts running either side of the conducting collar on the TT Axle, already existing.  Power will simply pass from the, battery side, Pick-up contact, through the conducting collar onto the second Pick-up contact, then to the Simmer PCB.  However, at the 000deg and 180deg TT positions, power will no longer pass through the collar, due to a single insulation stripe down the collar, lying under one contact at 000deg, under the other contact at 180deg.  Simmer sound will simply switch on and off, either side of the loco loading positions, without need for additional controls.  A narrow stripe of my daughter's finest nail varnish will provide the said insulation stripe.....   Shhhhh!!

Clever stuff Julian.  I'm afraid my own limit is being able to control a Hornby Vent Van with the DCC sound system!  It makes me smile.

Yours sounds pretty sophisticated but I'm sure it will be effective.

I don't know if this is of any interest to you:

I used it for my RC Boat horn.  All it basically does is play through the sound files held on the Micro SD card.  Powering it on starts the process and it restarts on the file it finished on when powered off.  I powered it through a switched relay so I can operate it from the transmitter and only have two files on the card.  The first is the horn and the second is the theme tune to "The Dukes Of Hazard".

I like that sound card that you referenced there, fantastic price, too.  Assuming the correct voltage could be provided, it would do the job, with the same simple collar switch I want to use.  I couldn't see if it had a volume adjustment, but simple adjusting the volume before loading the sound file would get there.

In truth there is nothing in the slightest complicated about the set-up of the system I'm doing.  A PCB, with attached Spkr, as purchased, with a rotating on/off attached round the TT axle, made from a pair of pick-ups and a collar round the axle.  {Not to forget the stripe of nail varnish to break/make the contact with the Pick-ups as it rotates}.  That's literally all there is to the set up.

I can't remember without checking but I think the player must not be run above 5 V.  I used a voltage regulator to step down the 7.2 V from the main battery to provide power for the player.

Pete,
I, already, referred to the loco sound on the TT, in my post, that was, indeed, the subject of the post.  

I, therefore, haven't "  Have you found a sound file of a turntable to super-impose on the loco sound? ", as that wasn't the point of what was required.  If I had wanted to do something of that kind, I would have already fitted a DCC Sound Decoder, with the relevant sounds on it, rather than the DCC Decoder I have fitted.

The clips you posted were very interesting, but clearly not relevant to the specific topic and would be just as enjoyable, as ever - but elsewhere.  Perhaps they would be good for your new topic Sound, sound advice.

regards

Julian

Morning Julian,
Having reviewed your posts, you have changed my ideas, thank you.
Whilst it may cost more [l had the car head unit and speakers], l can see that my sound source nodal point would be focussed perfectly. Of course it would, it's mono.
So, I can see multiples under my specific spots, giving an overall melange much easier than stereo manipulation.
Thanks again,
Pete

Ok, back home after a week with 3 "enthusiastic{?}" young teenage girls.  Have you any idea just how much noise they can make??

Talking of noise, I promised a video of the Simmer, so before it gets fitted fully, here's {So tempting to miss-spell that!} a taste.

It is considerably larger than those little Sound units BB mentioned 5 posts back and I can't imagine it sounds any better either.

https://www.ebay.co.uk/itm/MP3-Format-U-Disk-TF-Card-decoder-board-module-amplifier-decoding-audio-Player/272037297057?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 

I suppose there is some advantage in having an adjustable volume and the sound already loaded.  It may even get used for making loco sounds, behind a small Shunter - maybe, at some later time{?}. 

It will take a few days, to fit, as M-in-L is due descent and the Workshop has to pretend to be a Dining Room again - looks ridiculous with all those knives and forks on the bench!!

Regards

J

PS, the on/off switch will be supplemented by an automatic on/off which will operate with contacts either side of the Meccano collar attached to the axle [the pencil point shows it's location.  A small vertical stripe of insulation will break the contact around the points of rotation where the loco drives on or off the TT.

I am going to have to save up for the adm as reliability is king on my layout as it is at work.  I am surprised someone hasn't made the effort to upscale this design make more of them and bring the cost down - obviously respecting the intellectual property and rights of the designer

All motorising kits I have seen have been cottage industry attempts to make something from readily available parts,largely off the shelf. Good on those who have a go but often they are noisy and less than ideal.

As to upgrading the concept, it is a matter of both user abilities and economy of scale. Most Peco turntables are never motorised and a significant number are never even assembled after purchase because the average modeller is not too confident wth such things... so anything that needs the kit to be "adapted" will immediately put many off unfortunately.

Basically, its simply a small market. Doing anything that needs tooling to do it well will be expensive. There are other brands out there that do motorised turntables but they are expensive and that represents high amortisation costs / low production volumes.

Having said that there are some great options. The ADM is really nice -  the Heljan RTR turntable is also not bad at all and quite reliable if you can find one. given the reality of things, neither is really expensive.

I liked the look of the ADM, very nicely put together, indeed and well worth the money.  

I passed on it because I had seen them being driven by DC Loco controllers and I liked the idea, although it is easy to see why many prefer indexing.  I went DCC, Loco control, simply because of getting the power from a single DCC Bus, rather than adding a second DC Bus and the additional connectors.

I am looking forward to seeing you project progress.
