WiP: LEGO® SJ Litt. S1 Sound
I added a little gimmick today and it works better than I thought...
The noise is synchronized with the wheel by means of a tiny optical sensor and a reflector disc on the 1st coupled axle (4 exhaust blasts per wheel revolution). The entire sound equipment comes from Mobatron in Switzerland (mobatron.ch) and is actually designed for "real" model railways.
The module is supplied with constant voltage via the Buwizz and can be switched on and off remotely independently of the motors. When it's on, the wheel-synchronous steam sound starts up automatically as soon as the axles rotate; when the locomotive is at a standstill, there is a hissing sound, as is produced by the boiling boiler water in steam locomotives.
