Class 37 with ultrasonic smoke

Class 37 on Loch Lochy with dual experimental water based atomisers controlled by an on board arduino nano.

Can you make it blacker and smell like exhaust?????
No but seriously that is impressive, very nice shot that.

[@markhaynes8909]

i was going to ask if it smelt of exhaust too.

[@JulianBest]

Thanks, I've not tried making it blacker but I suspect any impurities in the water could clog up the microscopic holes in the membrane that produce the mist.

This looks amazing! Can I ask how you hook up the Arduino to the sound chip, or does it run independently of the sound chip? I have just bought some atomisers and would love to give this a go! Best wishes, Phil.

I've just connected spare function outputs from the DCC chip to the Arduino inputs. It's on my list of things to do to look at using the Arduino to decode the DCC for the loco address and then it could control the "smoke" automatically depending upon acceleration etc.

@@JulianBest thanks so much Julian I shall give that a go when the ultrasonic units arrive from Amazon. Looks so impressive on your locos-best diesel smoke effect I've seen.

@@JulianBest PS - apologies I should have asked this in my earlier reply - I assume you are controlling the smoke manually by toggling the function on and off to activate/deactivate via the Arduino Nano? Sorry if I'm being dim here! Thanks, Phil.

@@philporter680 Yes, you are correct, at the moment it's manual.
