About:
Let me show you how easy it is to create DIY studio microphones from a large diaphragm electret condenser microphone capsules, under $20 with discreet parts, no matter how complex you may think it is. I'll also compare different sizes of electret condenser microphones, and analyze how does their sizes affect their audio quality.

If you have a feedback or opinion, please let us know in the comment. This is not just a figure of speech, or to satisfy the "algorithm". I'm genuinely curious about first-hand accord/feedback. Be direct... I have a fairly thick skin, so don't worry about coming off too harsh. It's all good!

Audio level came out 6dB lower than it'd have been optimal (oh the irony)... Oh well, something to improve on the next video, I guess!

Personally I didn't find the audio level low. It's quite all right. Nice work. 👍

thank you so much for this . i saw Diy Perks and bought two cardiod electrat condenser microphone capsule but i couldnt find the exact transistor shown in that video when i searched for ulternatives for lack of knowledge i bought bjt transistor then mosfet transistor haha but not jfet and when i bought a j fet to be exact 2n5486 n channel jfet the whole preamp circuit was a mess (way out of my knowledge) but your pre amp design is just much neat and helped me understand the whole structure of Diy Perks preamp circuit . But i still request you to make a diy condenser microphone preamp circuit(full) because its clear you have a better knowledge on this and you know to simplify it. Again thank you so much

@@moumitabanerjee251 it would be wonderful if you build a simplified version of preamp circuit(simpler than Diy Perks haha) for usb version to direct plug in to pc without the need of an audio interface .Big Fan Thank you

Nice! I've made dozens of mics using electret capsules from 4mm-9mm. Just as easy to wire and use as you show. But I was surprised to see that larger capsule running of of plug-in power. Simple!

Absolutely... they're brilliant little things, but not as high-maintenance as we often expect them to be! Give it a shot, and all the best!

I'm definitely going to make video on preamp (with a primer on audio signal levels); thanks for the encouragement (but not back to back video on audio equipment... so please stay tuned). Glad that the video helped you realize that DIY mics (especially electret mics like 2555B) don't need to be overcomplicated. Also, in DIY perk's video the pre-amp was unnecessary, as he was feeding it into the USB adapter anyway (which can work with direct mic level audio, doesn't need preamp'd line-level audio). If you're also using USB sound cards, then you can totally skip any preamp circuit... just use the circuit I built on, and feed it into the USB adapter's mic bias and ground (either with TRRS cable, or directly solder on its board).

@@BreakerSpace yeah that's understandable take your time brother (i hope not more than a month 🥹) i already subscribed😊

That's just wonderful. you made everything so easy . everywhere i go they say cardiod electrat condenser microphone needs phantom power to be able to pick any sound at all ,Diy perk get rid of the phantom power need but his preamp circuit is kinda hard. your's is just so easy Thank you so much . Btw i have a question 2sk596 jfet is typically used for mini electrat condenser microphone though it's understandable it has integrated resistor that's why you used the scavanged jfet but what will happen if i use 2n4416 or 2n5486 n channel jfet. actually there is a long list of jfet which can be great for vhf and uhf audio signaal so i am kinda confused. and it will be awesome of you build a preamp circuit simpler than diy perks but keeps the sound quality of diy perk's circuit (hihihi ❤) . Thanks

Yeah, simplicity is exactly what I was going for... thanks for watching, glad it helped. BTW, you can you most of those JFETs without much issue (but there'd be case by case variances). Just make sure to use a biasing resistor of higher value if the JFET is a faster one. And by high I mean in the GigaOhm range (higher the better). Don't use a MegaOhm resistor like me (I should have mentioned it). It basically forms a RC filter, where the C is that of the diaphragm & electret plate - higher the R, lower the C required for same time constant - meaning, you get sharper rise/fall of signal waves even with smaller capacitance. As I've said in another comment, I'll come back to the signal levels, level conversion, and amp/preamp circuits, but not with an immediate next video. Please stay tuned ;) meanwhile, if you're really in a rush, look up for a MAX981x module.

Hello, I had a question. A few months ago, I bought a condenser microphone from AliExpress and wanted to know if soldering the capsule you use in the video to the circuit would work well (I have no previous knowledge of electronics).

If you can give link or model number then I can say with more confidence, but at the end of the day, all condenser mics work on the same principle. You might need a high polarizing voltage for true condenser mics (i.e. non-electret ones). Otherwise it's all the same (multi-stage signal buffering/amp).
