That's what the early radio pioneers used. |

He didn't want to try it. I could put a gallon of water into a target about 60 feet away. (PVC pipe, a pump type bladder tank for an air reservoir and a solenoid valve.) Sounds like an idea. Although a good shot of water would probably do a whole lot more damage than a pellet. But, it wouldn't be 'shooting' it. Can't wait to read about the next hobby...stamp collecting? |

I assume that really just means if they want the pictures in court. If they just use the drone to "get lucky"" on something like a traffic stop and they lose the drone images, I doubt anyone would even know. It is still the wild west as far as privately owned drones tho, BTW it is illegal (federal law) to actually shoot one down, it is an aircraft but I am not sure that law has really been tested on a drone. Say what?? https://www.youtube.com/watch?v=RR5BtXP0s0o 18 US code 32 (a) Whoever willfully-- (1) sets fire to, damages, destroys, disables, or wrecks any aircraft in the special aircraft jurisdiction of the United States or any civil aircraft used, operated, or employed in interstate, overseas, or foreign air commerce; ... shall be fined under this title or imprisoned not more than twenty years or both. I'm not sure of how the laws read in the case of a toy-like drone, bit I don't think any kid who has one will be interested in having it registered, titled (as home built or experimental) and having number decals on the side. (not counting insurance too!) to make it a legitimate 'aircraft' |

Believe it or not one of the most effective types of jammers is also the oldest and first type of RF transmitter used. It's called a spark-gap transmitter and it generates RF interference across a very broad range of frequencies simultaneously. The operation of a spark-gap transmitter is illegal now-a-days for exactly that reason but are simple to make and can be of more than enough power to temporarily wipe out communications to virtually any radio controlled device. And some things you really don't want to interfere with that will draw attention. Controlled bandwidth jammers are pretty easy to make and way less obnoxious. |

More fun would be a hardened backyard toy chopper of your own, armed with sharp steel rotor blades that could be used to slice and dice the toy choppers of nosy neighbors whose devices violate your air space. Chopper wars! It's the 'Merican way. One can envision the escalation, all the way up to MINI NUKES, available soon from the NRA. |
