Organized by IRZU, specifically by me - Matevz Leskovsek, main developer and ceo. When there will be at least 5 participants (and will have time available on same day) we will organize an online workshop, and I will personally make sure you are able to build your own smartdrums on your smartphone. You'll need to pay 100€ to paypal support@breathinglabs.com to join this workshop + you need to have about 10€ ready to spend in Google Play so you can purchase few utilities that are crucial for smartdrums as they make android runtime better. Root is not required, but it doesn't hurt if you have it. Android only at the moment, we do not work on iOS or other OS smartphones.
