we will start some kickstarter or other means to raise funds for developing prototypes. The goal for such fundraiser will be ~10k .. 15k EUR, and it's not yet decided if and how this will already be a (partial, 15%?) preorder as well. There's a certain minimal but non-zero risk that by circumstances we have no control about (components show fatal defects, known as Silicon Errors, etc) the project still may fail during that phase, so this is kind of venture capital anyway. (...) let's hope 200 preorders come in, we start "Mass" Production, and 4..6 weeks later the devices should be ready to ship.
