Short project - long video. But it is more educational this time providing some info about analog handling of sound and where noise comes from when you try to record using your computer.
Best instructional video I'v ever seen. This is the BEST way to learn anything on youtube. Please make tons of videos like this! Thanks man for making this video! :D
Best lesson I've ever taken about electrects! Very well explained, now I know what every component is used for instead of just following a recipe. Many thanks!
What a phenomenal tutorial. You explain things in a way, that makes it easy to absorb, and understand, unlike mainstream academia which teaches in a very sterile, and emotionless manner. Because of you, and the way you connected that Electret Mic to an, "O-Scope", I finally understand the minuscule amount of voltage produced by the Electret, and why one generally needs to add some type of amplification immediately following the Mic. All I can say is Thank You for making learning, intriguing.
I really like this video. You explain why some parts of the circuit need to be modified/upgraded to a better schematic with more components. As far as a video which teaches you the WHY aspect of things, this is second to none. Great job explaining yourself and why you built it the way you did. If only all my teachers I encountered through school explained the WHY part as well as you do in this video! Thumbs Up!
There are several things I really appreciate in your video. You first show is what type of output that comes in the Oscilloscope. Then we know what we are dealing with. They you develop the most simplified amplifier. No gimmicks, just a simple amplifier. It does a good job. Things work. If it works, cant complain. Enjoyed your video and recommended to my younger brother too! I learnt a lot having a decade experience in electronics and my brother will learn a lot too. Thanks.
Loving your channel. it's inspiring me to learn electronics to be able to do projects like this. I'm looking forward to seeing your usb driven professional studio quality mic
Built it and used it as input to an Lm386 audio amplifier IC. Works. Also, a good explanation of how it works. Cheers. I will add it to my Electrocircuit page.
The way you explained it explains and coincides with a recent experience of learning about pull up resistors in SPI communication in Arduino. This is similar. I can now see how they are used in your circuit which seems to be a very clean, simple and pure circuit. Good luck on your microphone idea.
I know this is an old video, but I built your circuit, and I made a correction, to get way more gain and to not cut off the low tones -> replace the 100nF caps with 47uF ones. Much better! Great video by the way :)
thank you so much for the video, you explain the circuit diagram in a way that is easy to comprehend and allows one to understand how the components and each part of the circuit works instead of following directions with no fundamental knowledge. keep making. vids
Greetings from India.This is the best demo of electret microphone amplification project I've seen. Very methodical, step by step aporoach, principles working, reason for capacitive coupling/ dc voltage elimination , amplification , displays, circuit diagram, intermediate and final results make it a delight to watch.👏👏👍 kudos. Some oops moments make it more interesting and lively too😀 Look forward to more
Shit! I think I just subscribed on purpose to someone who gives GOOD detailed explanations of what he's doing and why it's working/not working. I hope all the videos are like this. GREAT JOB! THANK YOU!
This is awesome! A note: *PLUGIN POWER*! Google it! I didn't know myself about this until a few days ago, but apparently there is around 3V coming from the sound card at the mic plug, specifically to power electrets. I'm not sure of the current capabilities or if you can drive a transistor amp with it, but if you can and it's clean enough this design can be used without external power. I'm thinking of trying to make a passive noise canceling arrangement with two out of phase electrets that can be an add-on mic for headphones.
Thanks. I thiiiink... I followed,... just about... perhaps one where I have to experiment with the scope a little as I build it to understand what goes on with the voltage levels (was a little lost as to where the 0.8v came from) or try on the javascript circuit simulator to get a better idea of what goes on. Really appreciate you building it up as gradually as you can though and showing what comes out at different stages. No one else does that that I can remember. Really helps with the learning.
I wasn't able to eliminate distortion with this circuit. In the end I went for the LM386 preamplifier circuit and worked perfectly. I have a great soundig condenser mic in my guitar now and mix the signal with the undersaddle piezo.
This reminds me of an amplifier experiment I made a long time ago. It was a 2 transistor, 2 transformer push pull amplifier that I connected a 24inch speaker(with it's own transformer) to the INPUT as a mic. and headphones to the OUTPUT. I was outdoors and could hear someone whisper from 50 feet away.. The amplifier was powered by a 9 volt battery.
Your video is superb. I am doing a mini project named multi purpose listening device in which i have to do the work which u explain in your video . Bcoz of yours i got a idea how to do
Hey just quick question, do you think we can connect this to a phone instead of a computer's sound card and still get the waveforms?? I installed wavepad, which is like audacity but for phones.
Hi, very nice tutorial, +1. I wannt to ask if you can show us stereo amp with dual these microphone, using PC Line input. Thank you and Merry Christmas.
I want to use an electret microphone connected to a stethoscope so I can hear the blood flow would you use this preamp to do the job any suggestion would be good thanks
