So, I was lying in bed last night (because this is the sort of stuff I think about when I can't sleep) and I hopped on the old googlemachine and found the ESP32-CAM module, see here: https://www.dfrobot.com/product-1879.html The basic gist here is that it's an ESP32-S2 mated to an OV2640 camera (2MP). Now, that's not super interesting, until you look at the ESP32-S2-MINI-1: https://www.espressif.com/sites/default/files/documentation/esp32-s2-mini-1_esp32-s2-mini-1u_datasheet_en.pdf It's a module only slightly bigger (20mm x 15.4mm x 2.4mm) as the ESP-12S (16mm x 17mm x 3mm), which means we might be able to fit it. Now the one thing I haven't done a pinout mapping study. As in, is it possible, with a custom board fab, to add a camera without losing some other functionality? I've ordered one of the modules this morning so I can mess with the code and get the video streaming working. Code will be up on GitHub. Anyone interested in playing?

The key piece that differentiates simple steam sounds that I’ve found is that the typical diesel start -> idle -> run sequence of operations doesn’t translate to steam. I think all that would be needed is to have the code be able to be set to return to “idle” with some parked steam locomotive sounds. That and a steam whistle option instead of a horn! Otherwise the speed and function control stuff works really well running the locomotves and customizing the rate of acceleration, deceleration, and coasting. I’ve fiddled with .wav files for sound and loaded them onto two different locos - though my sound volume levels & chuffing ‘speed’ need work. I’ve got a rambling attempt at an explanation here...

LocoFi is claimed to be an "open standard": So where can I find this standard - i.e. communcation protocol, so that one can write custom app to control multiple locomotives, or implement custom decoders that can communicate in the LocoFi protocol?
