![]() In my experience, i have been in several accidents due to neglectful drivers and others not following proper use of the road, they get no legal penalty and I end up having to pay the cost due to the fact that insurance is a scam that never pays out without a more expensive lawyer. Makes me smile, but I would get in more legal trouble than they would for smashing into someone with their vehicle “on accident” when in fact their neglect and inability to focus on operating a machine is the real fault. But the thought has crossed my mind more than once of being able to smash a button and silently disconnect their phones rather than having my life and property put in peril. There are various drop ship chinesium websites that will sell you various frequency jammers that are likely not legal without having a proper use case or exemption. Then they go right back to staring at their phone again… so i smash my horn again. And then they get mad at me for smashing my horn when they almost hit me or someone else. One thing that has always peeved me off is when people are driving around staring at their phones. I went back to read the hobby king fine article. Posted in Wireless Hacks Tagged FPV, video transmitter, WiFi Jammer Post navigation If you want to build your own digital video transmission, take a look at the Wifibroadcast project. If you have any ideas on what is missing in the VTX circuit, drop them in the comments below.īuilding RF circuits that interfere with the legitimate signal around you, or broadcasting out of band, is generally not a great idea, and could earn you an unpleasant visit from the authorities. With a signal generator to create a simple input signal, and confirmed that it interfered with his laptop’s WiFi connection.Īfter more experimentation with other VCOs, the closest came to success was a barely identifiable image transmitted using a Maxim 2.4 GHz VCO. In an attempt to confirm that the VCOs produced the desired frequency, he ordered a similar 2.4 GHz VCOs and built a short range (20 cm) WiFi jammer. This failed to produce any identifiable image on his video receiver goggles. He bought a couple of 5.8 GHz VCOs from Aliexpress, and created and used a simple opamp circuit to boost the FPV camera video signal to the required input level for the VCO. It is essentially analog video signal, frequency modulated onto a 5.8 GHz carrier signal transmitted through an appropriately sized antenna.Īfter a brief failed experiment with a simple circuit built from discrete components, turned his attention to voltage-controlled oscillators (VCO). The technology is very similar to the old analog TV broadcasts, but mainly uses the 5.8 GHz license-free bands. The video quality isn’t great, but it has the advantage of very low latency. While digital technology has caught up to the FPV world, a lot of systems still use analog video, especially for drone racing. After flying and crashing a cheap FPV drone for a bit, decided to try his hand at building his own video transmitter, which turned out to be a lot harder than expected. The proliferation of FPV drones has brought a flood of cheap wireless video tech.
