  • - What do you think about this? see, and tell us now.
  • - Very nice video. I love minimalism. How did you determine the two coil ratios?
  • - Does it matter if your wires are uninsulated? 
  • - would it work to use a dipole tuned for a specific band ?
  • - Can a silicon diode be used?
  • - Great presentation This will be our grand kids project for this weekend
  • - i can not find the germanium diode 1N34 is there any alternative for this ?
  • - Hi, could you please tell me if the size of the wire used in the coils is important? or is it just the amount of turns? will any wire do for use as coils as long as there is the right number of turns on each?
  • - If I have a 10 coil next to a 90 coil, will it work? And if I must change it to 25/90, does it matter if 25 is 24 gauge and 90 is 22 gauge
  • - inches or cm
  • - will it work in any continent??please reply asap.
  • - man! i love your channel
  • - Hi I was wondering if u could make a video on a tasla crystal radio aka Tesla spooky radio there isn't any good instructions just bits and pieces of photos and your the best crystal radio video person I seen on YouTube .. I asked the guy to help me and he didn't reply. A video on how to build it would help many people .. it doesn't half to look that way exactly just so it works... 
  • - I have thicker copper wire, does that work too? and if it does does it need less turns?
  • - Do i have to make 25&90 turns for 0.806 MHz oscilator also?
  • - The two aluminum foils are not connected to each others so why when you put it back and forward the wave change? Please explain to me !
  • - Can you blow out the speaker if the capaciter is set wrong?
  • - a cosa serve l'oggetto fatto con la carta stagnola? quali sono le misure? graziewhat is the object made ​​with aluminum foil? what are the measurements? thank you (google traslation)
  • - I would like to know were to find the 1n34 diode, and is there a replacement.
  • - I only see a 1N34A germanium diode online, not a 1N34 germanium diode :s
  • - I really liked this video Rimster but i got a question i want the measurments and calculation of the resonator i want to develop this in to pulse generator any suggestions?
  • - I might not have quite catched it but- it is only the wire you bought from radioshack that is magnet wire, and the rest just ordinary copper wire?
  • - Bekijk deze video op YouTube:
  • - Do you work in Tokyo Universty ?
  • - what is the thickness of the wire used to make the bobbina? Whether you use wire for the antenna? thank youtranslated by google translatorqual è lo spessore del filo utilizzato per fare la bobbina?Che filo usi per l'antenna? grazie
  • - Hey, where is the power source? Reply asap please :-) ... assignment
  • - I just started working on this thing today. I got as far as the coil, but I think I did something wrong: my coils seem to not take up as much of the tp role as your's does. I did count the wraps. Did I not count right? Please help.
  • - Hi great video, so i have an antenna question. So i figure i need a 44 [m] antenna which i dont have. I am in the us, my house has a ground for the 120[v] and a neutral for my 230[v] (both separate i think). Can i use the neutral 230[v] line for an antenna?
  • - I've made your radio but i only hear some sort of buzzing sound....Do you have any idea why?
  • - Or just take a radio from the looted Radio Shack after world war 3.
  • - Oh man! Mom's gonna be seriously upset when she sees what you've done to the dining room table leaf!
  • - Neat.
  • - Can imonitor 2 meter signals with a crystal radio
  • - Can I make a tuning bar out of a soda can? 
  • - Thanks for sharing.
