Projector or eval board: Projector should be fine for v1, if we want to play around the firmware we should get the eval board in further iterations. With just the projector - we need to send an image over HDMI and use an external UV light source. With the Eval board - we can look into changing the optical train sequence to our needs - LEDs, the RGB wheel etc
