    I present today the c1969 model 200 argon ion laser from Carson Laboratories of Bristol, CT. The ad and new product introduction below are from Laser Focus of May, 1967. The laser is long and heavy and missing its feet so it will be a while before I get a replacement set made and put it...

    Well if the two accounts can be merged and I don't lose anything from my james account, I'd be happy to get James Lehman back. If I have to set back time to the end of my James Lehman account and lose all my current stuff, I'd rather not. Thanks! James.

    Joy, user group spam, the best kind. That feature was disabled for years and I only recently enabled it, so I guess that explains how it got through. The bounces I am seeing are related to the account you are currently using and you have the ability to update your email address for it. As for...

    I can see 12 Spams about online prescription drugs from user philip. I can't use my real email address of james at akrobiz dot com. You blocked the account James Lehman many years ago. It's associated with that account. James.

    I have a multi pronged spam prevention system running here already that appears to be running well enough. Are you getting pm/post spam here and not reporting it? Also: update your email address on the board. I'm getting spammed by bounces from your previous host.

    OK - A mobile airborne anti-drone system is quite a bit more complex that the ground-based station I was discussing. For one, you now have a much higher intercept velocity because of the movement of the plane (which is likely to be much faster than the drone). Also, you don't want to interfere...

    Discharging a shot gun near airports, neighborhoods, city limits, etc is SUPER illegal and because of the noise and relativly short distance (camera on drone can capture you) its super easy to get busted. Range of a shot gun is extremely paltry and you could end up hurting someone else with the...

    You could install your circitry in a farday cage and be fine, of course the entire engine compartment would have to be protected as the emp could travel through any exiting wires. EMP's are cool but a real emp requires explosives and a massive AC power supply and I don't like messing with...

    In the case of passive jamming my thoughts were towards protecting aircraft with occupants (where its impossible or impractical to install a laser) and the power supply is somewhat limited on small aircraft so a targeted jam with destructive interference is far preferable to flood the air with...

    Shotgun works well. My real question is what are YOU trying to hide and from WHOM. You could always fly a second drone into the first. Train a faulken use a bright spot light to blind the camera. Use a laser to destroy the camera

    Because a directed energy weapon can act at far greater distances, probably. But yeah, for close-in work a physical intercept is pretty lethal and a lot cheaper. Agreed. Although to be fair the military is currently investigating directed-energy weapons for anti-drone work. But yes,...

    There has to be a branch of chemistry for crystals, “crystal chemistry” on how to make synthetic crystals? https://www.youtube.com/watch?v=XbBc4ByimY8 Using the Czochralski technique new crystal types can be made in the same way silicon wafers are made

    We are becoming more and more of a police state where everything is illegal. I can’t even keep track. The more esoteric the law the harder (or almost impossible) it is to enforce. If you turned on a passive jammer (only turned on when a signal came on) it would take considerable resources to...

    Any form of RF jamming would likely be illegal anyway. Unless you're the military, in which case you already have those capabilities.

    Electronic destructive interference is just as complex as developing a new laser material due to the extremely high radio frequencies that drones and gps operate at. It would require complex mixing and digital signal processing in order to detect a drone signal halt the sensing antenna and then...
