This is the BPNVG, generation 2. This uses the same internal parts as the gen 1, but has a more robust, more durable case.
Internally this uses many parts in common with previous open source night vision devices as the Openscope, and the Eagle Scope. The Runcam Night Eagle 2, originally used in the 'Eagle Scope' 3d printed NVG is advertised as needing only 0.00001 lux illumination. (Lux is subjective and I do not believe this) and will function considerably better than the naked eye outdoors. If there is sufficient overhead foilage or you are indoors you will still need an IR illuminator.
The biggest advantage to the NVG is not night vision itself, but the ability to see other active night vision devices, like security cameras IR spotlights, and weapons systems or designators using IR invisible to the naked eye.
This device requires:
This means the overall cost to make this should be under $1000, including the printer.
Parts to print:
The order of operations are as follows:
The BPNVG will now be complete.
The BPNVG can be focused by rotating the lenses on the front of the sensors. The BPNVG if properly sealed, is waterproof to an undetermined depth. The BPNVG can be purged, or dessicant added through the mount holes. The BPNVG can be used with one half of the unit left or right, or the entire unit can be assembled with only one screen and sensor as a monacle with the optional single tube and lens holder for single or simple binocular use, with an overall estimated cost near $150 for the single monacle. No single part of the BPNVG is ITAR regulated and this device can be sourced from components in any part of the world. The BPNVG can be used with Short Wave Infrared that is undetectable with military standard intensifier tube based NVGs.
