As an electronics student I am astonished at your enthusiasm. Today we have reached an age where anyone can learn anything. I also kind of want to lean everything I learn from the scratch. In this case, starting from doping of semiconductor no, more back starting from mining and identifying semiconductor materials to making diodes to building radio or television or computer. (ha ha kidding its impossible for me to learn mining, chemistry, physics, engineering on my own). Well I have got friends of different majors. Lets see where i can reach. God knows
This is a good video, good presenter. Passion and curiosity and being humble can allow one to cover topics beyond one’s expertise and add something meaningful to the conversation as well as make it accessible for population other than college educated men or other privileged figures with resources.
поздравляю, американка удивляется тому, что делают российские школьники на рубеже средней и старшей школы. деградация на лицо............. только это конечно делает сeкcуaльнaя рыжая девушка, а не советский дед...................................
GURLL. I ALWAYSS get this idea of knowing how to make anything from scratch incase war happened and humanity went back to zero, with no internet, batteries, bluetooth…and omg I srsly can’t believe that I’m not the only one. PLEASE KEEP THESE VIDEOS GOING (altho I’m still in the first min of this one😂)
Yup, and now I am an amateur radio operator building my own transceivers. A hell of a drug, just sitting in the dark listening to some Chinese radio broadcasts
well done! the capacitor and inductor (coil) make a resonant circuit which "amplifies" that specific frequency you want to tune to. it will be MUCH better with a capacitor (of the correct size) if you want to ever revisit. and the antenna design also makes a big difference. But you did it! 🙂 ps - love the hair!
This is so cool! I am an engineering student in Italy, but I never tried actually building a project with what I've learned because I never felt like I actually had the comprehension of it, but seeing you try and retry has inspired me to try it and see where it brings me. Thank you for the entertainment, if you see a video about a dude building a small DIY wind turbine you know what inspired him
Optical Physicist here and I just want to say how happy I am to have found this. Your enthusiasm and willingness to do something wrong over and over again is really inspiring and more rare than you might think. I'm sure your next version will be phenomenal. Now for the technical comments: 1: Using the resistor is good, but if you want to amplify the signal more then you'll want a larger resistance. If you are currently using a 10 kilo-ohm resistor try bumping up to 1Mega-ohm. If you want to get really fancy then look into transistor based amplifiers like the Transimpendence Amplifier. It will allow you to get absolutely huge amplification without as much noise. 2: You should absolutely be able to use that speaker from the fire alarm, you probably just need to get the input voltage right. This will likely require looking up the datasheet for the part and figuring out what voltage it wants to see and then see if you can amplify your signal to that voltage. 3: Your ground is fine, but you could also just use the ground on your wall-plugs. 4: You can change the station you are listening to by changing the induction of your coil. This can be done with a ferrite core by inserting inside the coil, which will change the inductance and thereby change the resonance frequency of your circuit. This is a great way to tune to different stations because you can just move the rod in or out. Best of luck!!! You rule dude.

CURIOSITY KEEPS YOUR MIND HEALTHY AND YOUNG, YET, US OLD FARTS, THAT STILL ARE RETAINING THEIR DATA BASE IN THEIR BRAIN, WILL GET THE GIFT OF REVIVING THEIR CURIOUSITY AGIAN ;-)
