If you wanted to be a total pedant you could have pointed out that the pairs of fans rotate at different speeds in real life too..... But then pedantry for the sake of it is, well, you know..... ;-) 1 Link to post Share on other sites More sharing options...
G-BOAF Posted February 3, 2021 Share Posted February 3, 2021 Presumably given servo-operated pantographs, there is now the technology for rotating roof fans... Though I'm guessing the mechanics might need to be more robust than a short-burst pantograph system Link to post Share on other sites More sharing options...

Though I'm guessing the mechanics might need to be more robust than a short-burst pantograph system Really you want the fans powered by a separate motor, somehow tied in with the function for the roof fan sound. That is beyond the direct capabilities of the current decoders without bringing in relay some power switching. You are looking at about 100mA max on the function outputs today. I have been toying with putting such a motor in my Hornby Class 56. As yet, I haven't sorted out a) how to power it and b) a small enough motor with a sensible speed. Are we likely to see decoders support this sort of thing? Maybe one day, but I would put my money on having them doing two speakers on different channels first so you an separate high and low frequency sounds to appropriate speakers.

RMweb Gold Accurascale Fran Posted February 3, 2021 RMweb Gold Share Posted February 3, 2021 We actually looked into this in the early days (servo fans), but it would've added another £40+ to the price IIRC, so we abandoned the idea as well as it being quite complex for durability. We have to keep the price somewhat competitive unfortunately. The belt driven fans arent prototypical so we decided against them. Cheers!

The LokSound V5 supports this - it's how we have two different speakers in the Class 55. 2 Link to post Share on other sites More sharing options...

But it’s two speakers driven on the same channel, not two speakers on different channels isn't it? I am sure there is only one pair of speaker pads on a V5 meaning all sounds go to both speakers. With two channels you could choose to have the horn sound on one speaker, and the engine on another.

Roy There are dedicated speaker connections on the board for two physical speakers for the O gauge version, the OO LokSound uses its onboard 3W amp and 'smarts' to run multi-speakers where each speaker responds to it's native frequencies. Our circuit boards are also designed by ESU to ensure these configurations run perfectly. 2 1 Link to post Share on other sites More sharing options...

Roy As far as I remember I read somewhere of someone doing this but doubling up two function outputs and assigning them the same Function key.

That is an interesting approach, but not one I think I would risk. Motors draw a lot of power as they start, even if there is a fraction of a second difference in the propogation delay of the function states changing, all that power will be drawn on one function.

RMweb Premium boxbrownie Posted February 3, 2021 RMweb Premium Share Posted February 3, 2021 Well TBH I took the fan drive out of my Hornby 31 as you couldn’t really see it as it only worked when the thing was moving past you on the track and it is such a small detail through the mesh and I wanted the space for a big speaker, and besides it is quite prototypical to have the fan stationary while the Loco is moving as well, my 7mm Heljan Locos are that much bigger (obviously) that it is worth making the fans move at a rate that you can actually see that rather than a invisible blur, might as well not be there......I think AS reasoning is a good one, they are such a small detail as to make an extra £30-40 for the “detail” just isn’t worth it. As an aside, I never had any issues with the Hornby fan mechanism jamming or not working either, though I did have one that got quite “squeally”. 1 Link to post Share on other sites More sharing options...

The Heljan 7mm diesels have separate motors for the fans, controlled with a variable pot which is usually set from the factory at the setting of “manic high speed crazy person” and has the noise to go with it it’s the main reason I adjusted the speed of the Heljan fans to be nice and slow so you could actually see them rotating and not drown out the sound from the sound chip, those Heljan fan mechanisms can be that loud! 1 Link to post Share on other sites More sharing options...

RMweb Premium PJ10 Posted February 4, 2021 RMweb Premium Share Posted February 4, 2021 Morning. Can I just confirm it’s Q3. Last I heard a delivery of Q2 was expected. It’s not a problem, just the statement “still for Q3” makes me wonder if it’s a typo. Several planned arrivals around Q2 and Q3 including your sound fitted 37s and 55s means I may have to use some “creative accounting”. Good job dealing with household finances is my responsibility. Really looking forward to them when they arrive. Thanks PJ10 1 Link to post Share on other sites More sharing options...

G-BOAF Posted February 4, 2021 Share Posted February 4, 2021 I would have thought (hoped) that given it was started and announced first, the Deltic would arrive first.

Deltic will arrive first, but as 37 didn't suffer the same learning curve delays, it has caught up quite a bit. We'll do our best to stagger arrivals at least a few weeks apart!
