Did you ever want to add *sounds* to your Lego models? Imagine how cool it would be if your favorite train would actually make train sounds, or if you could ring the bell to announce departure in the station you built?
I can show you how to hide a Makey Makey board into your bricks and link it to some triggers - hidden too.
The only thing that would be visible so far is the device you connect your board to.
I use such a system when playing music live. I designed a custom controller for my board and use it to launch samples on my computer using Soundplant. This way, all my live sessions are unique!
It took me about a week to put all things up, but I was looking for solutions along the way. You won't, so it will be faster!
