I don’t know much about firearms. I used to hunt when I was a kid growing up, but have not been shooting in over a decade, so I am out of the loop. However, this seems awesome. Sandia Labs has a proof of concept design of a self-guided bullet that does not use inertial guidance systems. Basically the bullet has some adjustable fins that an 8-bit controller moves as it tracks a laser illumination of the target. The picture below shows time-lapse photo of an off-target bullet with an additional LED flying towards a target. It is really cool to see the path change direction as the bullet zeros in on the target. I think the neatest thing about this is that an 8-bit controller has enough horsepower to control the whole thing. I makes implementing a robot or weather station seem all the more doable.
