content: So I spent maybe 1.5 hours trying to find a post that detailed the results of a high power microwave transmitter being accidentally pointed towards an apartment complex.Does anyone know this post? It was stitch-bustingly funny, but I don't remember what sub forum it was in or any keywords really.I tried searching for key terms like apartment but my searches come up empty.It might be a really old post, I read it over 4 months ago.

content: Haha, that was an amusing tale but not as good as the one I am thinking of, of malfunctioning lights, burnt out appliances and other maladies.

content: Quote from: Orpheus on March 28, 2013, 06:15:20 amReminds me about what we used to do. Take signal generator and tune the frequency to the desired FM station, add a 2m wire as antenna and feed into the modulation input the signal from another radio tuned to the desired jamming signal. Wind up the output level and turn on, and the one station is replaced by another, and no amount of tuning will get it back, as we were around 200km from the transmitter site, but were able to get stable low level signals ( big high tower that was just able to peep over the mountain range) reasonably reliably. Victim would tune radio back and forth to get the station, and eventually would realise what we were doing. Range of this was around 2 km, but to blank the legit signal you had to be within 50m or so.

content: I remember the time in college when a neighbor would play his radio really loud just to be annoying. I built a circuit to charge a 5uF motor run cap to 170V or so and then use a neon bulb and SCR to dump that into a loop of wire. Soon afterwards, I heard some loud thumping in sync with the pulses, followed by the radio being turned off.

Eventually I got frustrated trying to sleep so I got my laptop out and started sending him disassociation packets causing him and only him to repeatedly disconnect from the network. I thought I'd have silence but soon the socially inept neckbeard started banging on my door asking me if I'd take a look at the router (it sucks being the only technically literate person in the house), he also had the ISP tech support on the other end. The ISP had only one question and that was can other computers connect. Since the answer was yes the ISP said his problem was with his computer and hung up.The next thing I herd was the sound of a keyboard being smashed against his door frame.
