Need help to build a ChooChoo bike whistle (lemmy.world)

Hello !

I recently 3dprinted a train whistle that usually works with a mouthpiece. It works by simply blowing air in it.

However, I would like to convert it to a whistle for my bike. For that I would need a system that could blow air in it, instead of myself, with the press of a button.

Any idea on what i could start with to build that ? It would be best if the circuitry was quite compact too.

Thanks !

You could base your design off my favorite bike accessory, the Airzound bike horn
