I want to build a wifi jammer for an 802.11ac 5G wifi camera (its on channel 149). The camera is about 20 metres away. A 20 to 30 metre range would be ideal. I dont want to jam anything else e.g. phones or 2.4Ghz etc There are ‘off the shelf’ development boards for this sort of thing but I’m not very experienced with electronics and I don’t know what items to purchase. I dont expect the assembly will be very complex because it’s not being made from scratch but I'll still need basic guidance. If it is relevant I've done some very simple tinkering with an ESP8266 NodeMCU V3 board (which was when I discovered I could only Deathur a 2.4gHz wifi camera with it). I can do basic fine tip soldering but I wouldn't enjoy building somethi...
