This genera of video is invaluable. Shows the BASICS and explains how a technology evolved. Understanding these analog basics is the gateway to and of the digital world we now live in. Thanks for the post!

These old videos work because the graphics were primitive so they had to explain in detail.

that, and there was no pausing or rewinding so they had to recap things a lot

I'd love to see this turned into an interactive lesson where a student could adjust the conditions; carrier wave, type of modulation, various virtual tubes, etc. Regardless, this is just a fantastic video!

I love that this explains enough that it could be used to build a radio, actually useful information!

I feel like this doesn't really explain whats actually happening or how you would go about making a radio but still cool and funny

to make the diafragm use paper, or any other light material and something like graphite ground into small pellots from a pencil, copper wire to connect, a vacuum tube is a glass bulb like the light bulb with as little air inside thanks to a pump for the vacuum, to metal prongs are close not touching for a spark to fly between, a bit like the modern transister. this video gives enough to build 1.

Someone please help me! I have followed all videos trying to make super simple radio. I connect a battery to transformer which is then connected to a wire, and I put another wire about a centimeter away. The current went through the first wire but the second wire had no current going through it. Why in all videos I see everyone else can make radio and make electricity go through wire from a distance but I can’t? Nobody is explaining this so please help! None of the current passing through the first wire is detected by the second wire, and no matter how close I put it, nothing happens.
@arthurbomamigo3448 Жыл бұрын
Man, Im really no expert, but maybe that alternated current coming from transformer is not amplified, so it cant be transmited to the other wire. As seen in the video, they needed valves to amplify the signal back on time. Today we can make simpler amplificators from transistors, those are maybe the ones youre missing out

have them closer or a stronger battery, 1cm is small to humans but a big gap for the weak initial waves.

Funny, but it doesnot explain how radio works, only the magic processes in the transmitter.
