A few years ago, new, innovative pico projectors, influenced by one of the TI development kits, started appearing in Kickstarter projects and other various DIY endeavours. Those projects fizzled out, most likely due to the cost of the projectors, but we got a few laughs out of it: that wearable smartphone that projected a screen onto your wrist used the same technology.
But there’s a need for a small projector, a pico projector, or in this case a femto projector. It’s the Nebra Anybeam, and it’s a small projector that uses lasers, and it comes in the form of a Raspberry Pi hat. We would like to congratulate the team for shipping the ideal use case of their product first.
The key features of this pico projector address the shortcomings of existing projectors that can fit in your pocket. This uses a laser, and there’s no bulb, and the power consumption can be as low as 3 Watts. Power is provided over a micro USB cable. The resolution of this projector is 720p, which is sufficient for a quick setup for watching a movie, but the brightness is listed as equivalent to 150 ANSI lumens, about the same as small projectors from a few years ago.
But of course the big selling point isn’t the brightness or resolution, it’s all about the smallness of the projector itself. There is a developer’s kit, a Pi Hat, a fit-in-your-pocket version with an enclosure, and a ‘monster ball’ version of the Anybeam.
