Just installed a cheap soundcard in my 3d printed double diesel

Very impressive, sounds great!

I'd forgotten how good those hoppers look too, really nice...

I am having good success with the sound card MP3 players and have sorted out the files for this thanks to Rik. They work pretty well and cost less than a fiver if you buy in bulk from china, for me this includes a regulator set to 4.8v, just to be on the safe side. The speaker tends to be the most expensive bit but can't recall what I paid for them, but not a lot knowing me

Now added a second card for the horn - triggered by an output from the Deltang Rx61b (old technology but still does the job)

Did you use the same speaker for the second sound card?

No - I put the second speaker in the cab of the other loco. I've tried feeding two inputs into one speaker in the past and it doesn't work - the original volume reduces.

I thought it might as I had a similar issue when I tried a similar sort of thing, hence the question about it. Great in a dual can like yours, but takes up a lot of room in a conventional 16mm loco, unless of course it's an NGG16, I think I have room for a subwoofer, pre-amp, amp, mid range and tweeters in that, lol
