Intuitive and practical education. I wish I had this in school and in college. The mind just soaks this information up. Thank you for these great series. I just discovered your channel.
Hi Professor, you mentioned that the frequency that we're hearing from the radio at 07:25 is the frequency of the switch triggered by the motor. But the antenna sends the energy based on the oscillation from the LC tank circuit while the switch is opened and C1 is being charged by the battery at the same time. I assume C1 discharges to the LC tank circuit before the LC Oscillation dies down. So, is the frequency that we hear from the radio the LC Oscillation frequency or the switch frequency?
@@germainguerin3063 The more I've thought of this. It might be a bit of both. The LC Oscillation freq is probably a mean to an end. The switch frequency is probably the content of the message. When we hear the noise from the radio, we hear the content of the message transmitting via the resonant of the LC freq of the antenna. I'm just guessing...
You state 15 seconds into this "as you might recall, this circuit had two capacitors" Recall from when? Not the first "Analog Electronics #1" video. I think I know why, this is the same video as video #6
Professor,, would you please be so kind as to pin a comment with suggested values for R, C1 and C2 for those of us who'd like to have a go at replicating your 'motor-gap-transmitter'. Thanks in advance. Fantastic series BTW!

Nicely done! As a previous viewer has written would be would be nice to see some numbers

Good question i think it's at the tank frequency but if the motor is not in sync with the tank's frequency what happens?

Good guess, an oscilloscope would tell
Also great!

made it to about 3:00 before I felt dumb as hell
