A $50 head-up display with wireless augmented reality protocol

This is a surprisingly well-engineered and effective display, given the price point once injection molds are made. I've had the opportunity to try it out in person, and would love to tinker with one myself.

If you're at all curious or hacking-inclined, I strongly recommend backing this as it's one of the cheapest introductions to augmented reality you're ever likely to find!
