If you really wanted to, I'd recommend a microwave 'cannon'. You can build one yourself for cheap-ish based off a directional antenna and some recycled microwave-link components.
Then you just need to target it. Probably need some sort of weather proof retractable cover so that the neighbors don't freak out. Gimbal under the cover to aim the thing, and then a means of target acquisition. People have tried to use audible input to pick up the propellers, but I don't really know how well that would work in practice and what kind of / how many microphones you would need to get a fix.
The generally idea would be, system detects and gets a fix on probable drone, notifies you and allows you to do a visual check and give the fire signal. Microwave directional targets and roasts the target microelectronics.
- AlexCoventry 5y agoHow hard is it to shield electronics from a microwave blast? What impact would surrounding them in alfoil have?
- K0balt 5y agoPretty easy to protect electronics from rf energy.
- korse 5y agoYes it is, but most consumer drone hardware doesn't do a very good job of it. Also, most drones require a a couple of RF/EM sensors for position and heading which can't exactly be Faraday caged. I was being somewhat facetious about mounting a microwave auto-turret on your house, but the technology has been toyed with for years as a man-portable solution to consumer drone intrusion.
- K0balt 5y agoYeah, it would need to be customized for sure. Antennas can be filtered pretty effectively even in high rf environments, but they might be jammed. The Magnetometer will work in a box. Straight consumer drones should be easy to disable though.
- kova12 5y agoShielding might end up warming up and frying device with heat
- snovv_crash 5y agoNot if it also needs to have an antenna to listen with. That's always going to be an easy way in.
- K0balt 5y agoStill, can clamp it as long as the attacking frequency is out of band. Also, no real need for telemetry in most cases anyway.
- snovv_crash 5y agoNot telemetry, but usually C&C, GPS, etc.
- capeterson 5y ago> audible input to pick up the propellers Does not really work that well, as far as I've seen. One is probably best off using an SDR to pick up the communications between the drone and the remote. It's a rather inexpensive solution, as well. Microdoppler is promising for this as well, but that is likely astronomically out of the range of purchasing power for the average person.
