Thank you. This was exactly what I was looking for! I understand the formula and I’m broke so this is perfect. A few tweaks due to materials however perfect. Thank you
Whats interesting is, from what I understand you only need a power source to have a carrier wave to send signals through. Energy use is almost nothing. Now to amplify the signal for speaker use, there is power loss of course.
I have two ideas for improvement. 1: You could put the carbon through a sieve and try particles of different sizes. 2: Wouldn´t tape make for a better membrane? You can fill the soda can untill you get a small hump and then put on the tape with some tension. You could even put some aluminium foil on the glue covered underside.
While people are saying this doesn't work, the concept is there. Some tips for anyone wanting to make one of these themselves: Use a piece of paper or a piece of stretched balloon for the top, otherwise known as the diaphragm, as those will vibrate much better than the bottom of a plastic cup. You want powder rather than the small rocks used in the video. You can use the carbon in the video or carbon pencil lead and run it in a coffee grinder to get it into a fine powder, the finer the better. Instead of attaching one of the leads to the diaphragm, instead you want a lead on one side connected to the housing, and another inside where the carbon is. Make sure the lead inside the carbon is not touching the outside of the can, or else it'll short circuit and not produce any sound. I may post a video later if anyone needs any further advice.
Another thing. Why on earth would you post videos of you playing with soda cans and paper clips making junk that doesn't work, while telling us it works really well? Why not wait until you FINALLY get something to actually work, and post that one? Duh-
I mean it does work , were you expecting quality input from a soda can and a solo cup ? This is like some fox hole radio shit , but it does technically work if you were in some kind of pinch. And it gives you a somewhat basic idea of how a carbon condenser mic operates.
A carbon mic is one of the simplest concepts and *could* be a great demo & project for kids to try. Too bad your video is so poorly planned and executed. If I were watching it as a kid, I'd never make it to the end. I'd get discouraged by all your stumbling, fumbling, and failures. Your construction techniques simply teach a lot of bad practices. It would be great if you had tried this ahead of time, then when (IF) you got it to work, rehearsed your presentation. * So many technical flaws in terms of speaker connections, circuit impedance, etc. etc., I won't even begin to elaborate here. * PPPPP. Prior Planning Prevents Piss Poor Performance.
@@fryingpantothefacestudios6665 It was polite and factual with some very specific suggestions. It is called "constructive criticism." For example, when you take an exam for a driver's license, if you run through a stop sign the officer will say "sorry, you failed, you should not run through stop signs." That is constructive criticism. Re-read what I said, it cited some specific failures with the youtube presentation and made some suggestions. The OP can perhaps learn from my advice and become a better presenter; or the OP can ignore my advice. In either case, the advice is constructive criticism; it is not rude. It's commendable that the OP tried to show something, but he could have done much better. PS: I taught electronics theory and several computer courses, and was a lead trainer for my employer. I always prepared my presentations, and I got very positive feedback for my work. I am simply sharing some advice based on my own work experience. That is called "being helpful." There is nothing rude about that.
@@gregm.857 such constructive criticism would have been acceptable if the creator had asked for it in his video. Yes, more planning could have gone into the video, but it seems like this guy just wanted to show off this cool thing he learned, he didn't ask for anyone to bash his video or design. You may consider it factually correct and criticism, but it's still rude when he never asked for critique. I too have experience in the technical field, but I don't go to comments showing it off. One may have such skills, but that doesn't make them entitled to give criticism whenever they see fit. The way your comment was written doesn't come off as helpful. It had unnecessary sentences in it which aren't helpful at all and are truly just rude. You say that you want to be helpful, and that you were giving criticism, when all you did was say that the video was hard to follow, and when bringing up the problems that he presented, you admitted to not even wanting to explain, that provides no help to the creator, or anyone reading your comment. If you truly wanted to be helpful, you could have put more effort into explaining the process, and ways to actually engineer the speaker, along with elaborating on how to fix the issues you pointed out. Yes, I will gladly admit that the beginning half of the comment was constructive criticism, but calling the rest of it polite and factual is just wrong. Calling his video "piss poor," is blatantly rude. If you believe saying things like that is actually helpful, criticism, and not rude, you have pretty bad judgement. Since you're such a master in the technical field, stray away from that and hone your skills in empathy, kindness, common sense and general social behavior. Do a little self reflection while you're at it.
My uncle got me a 1920s carbon microphone a few years ago, this gives me ideas on how to get it working again
Thank you. This was exactly what I was looking for! I understand the formula and I’m broke so this is perfect. A few tweaks due to materials however perfect. Thank you
I'll definitely give this a try!
Don't you have to pulverize your carbon ? If you open the old telephone mic - it is full of carbon powder, not granules.
that might make the microphone better - but I was aiming for "simple" over "good".
@@rhettallain well, I never knew I can make a mic that simple. Thank you for your video !
Wrong! Old Western Electric carbon elements definitely have graphite (carbon) GRANULES, not POWDER!
Whats interesting is, from what I understand you only need a power source to have a carrier wave to send signals through. Energy use is almost nothing. Now to amplify the signal for speaker use, there is power loss of course.
Can you make it work with a homemade speaker made of magnets and cups?
Yes. Here's how to do that czcams.com/video/94A7uzaGct8/video.html

Would this sound like one of the old 20s mics
I'm never getting that 15 minutes back am I? 😑
the one without a battery i just saw earlier today, could you try a match box and carbon rod desigh
I would use smaller size grains of carbon

if you could post a video of a working prototype that'd be amazing
You, sir, should receive the STAR IMAGINATION award! 🤣

you're rude lol
