I've been talking with Lucky225 and throwing around the idea of building an open source laser jammer built here in the states. Not just some cheap pos that happens to confuse a lidar from a distance like a science project but an actual jammer with LI like performance. It would be based on good hardware, it would have the sensetivity of the zr3(4) etc but with a VERY powerful pulsed laser diode or diodes like an le10 but with software control. IT would have a fast user reflashable microcontroller and possibly some sort of lcd display for configuring and alerts. You could set for various levels of stealth for use in banned areas or set it for maximum jamming (a la le10) in non-banned areas or make your own code/algorythms and see how they work.
I've already got some ideas and will probably build a proof fo concept jammer as soon as I have a place of my own and a workbench again. I've also done some research and i'm thinking a you-build-it kit could be put together w/ 4 heads for around 250-300 and a retail assembled kit for < $500 depending on features.
You guys think there would be any interest in this outside of a few geeky members on this board? Maybe I could disguise it as a parking sensor and get a big-box retailer to carry it
