#SparkGap #Transmitter

  • Hello BOOMers, there are debates on that my circuit which has capacitor parallel to high voltage source is worse than the other type I also showed at 0:02 which has spark gap parallel to the high voltage source, because DiodesGoneWild mentions it here: While the purpose of this video was not to make a proper commercial transmitter, because FOR GOD'S SAKE, WHO BOTHERS MAKING A COMMERCIAL SPARK-GAP TRANSMITTER NOWADAYS... both circuits lack many components that could make them better, both would work fine with proper components and both have pros and cons. Like in my circuit high voltage resonance frequency is right across the transformer and although mostly filtered, could stress the transformer to some extent, while if the spark gap is across transformer, it could short the high voltage for extended period of time overheating the transformer. In either case having a larger series inductor to the output of the transformer could protect it better. But WHO CARES?! Both circuits work for demonstration purposes, and need improvement for commercial use. So don't go selling this junk to make money!!

  • Hi MR Boom, I noticed you sent SOS in CW or Morse Code. Although I appreciate watching your videos and your humor I don't think its a good idea to encourage the miss use of Radio or Wireless communication. FYI, even though your RF signal is weak, it can still travel a long way and be picked up by a listener or HAM radio operator. This SOS could be taken seriously and might even be classed as an illegal use of radio in some countries. I'm sure I'm being over critical, I don't think anyone would likely follow up on it.

  • if u want to make a perfect antenna u need to cut a wire longer than an half wave of ur frequency, for exaple a perfect antenna for 1.6 MHz it's long 187,5 meters, the formula for calculate the wave lenght is c/f where c is the speed of light ad f the frequency of the imput. If u want write to me searh my callsing on 73 de IU3MID

  • "While Tesla wasted time trying to transmit power wirelessly, other people figured out that they can use the same methods to transmit information." Absolut gold! Also.... do sick of all those 'tesla invented free energy' spastics. No he did not. He invented radio transmittion, but was to caught up in his dream, of wireless power, to realise it!

I was very very quiet, but i swear i saw my mom giving me the eye. Threw out the thing and the 1926 Popular Mechanics magazine that showed me how. Obviously it didn’t kill me, but i made up for it several times in my life...

I believe I have a subject in the continuity of the video under which I post: Easy to implement for a video, even if the risk of getting electrified is low, I think this would be a good subject for you. there is also this small series of videos which are nice:

    • Wireless communication developed all over the world around the same time, so there really isn't just one person or group that can be credited for the technology. Rowland developed his spark-gap transmitter in 1889, but Poulsen and Pedersen were among the first to design a transmitter that output a continuous waveform rather than pulses.

  • When I was a child I had a Red Radicon remote control Bus that transmitted a signal to control the Bus with a Spark-Gap Transmitter. Sometimes when the bus was close to the refrigerator, the arc of the compressor Contactor engaging would make the bus start or stop or turn. Here is a demo of one of these buses:
