The Ultimate DIY Microphone (super low self-noise!)

  • Published on 3 years ago

    Runtime: 9:36

    In this video I'll be showing, in overview, the design of my super-low-noise self-contained ORTF microphone rig. It features superb stereo, a built in recorder, triple shock mounting, and of course a noise floor that is so low that you can record the beat of ones own heartbeat in a quiet enough environment. Impressive to say the least!!!
    AudioBlocks link: audioblocks.com/DIYPerks_0417
    And the Rode NT1-a (for those interested): amzn.to/2BsJkwI
    In this video I'll be showing you how I made a portable studio microphone that has an extremely low self noise and a wonderful stereo soundscape. The quality of this thing is insane!
    Here's the preamp schematic:

Is there a difference in supplying 12v, 24v or 48v to a condenser microphone?

This is quite brilliant!  It's great how it contains lots of very helpful links and tips for other possible projects. My personal favourite was the shock mound which I think is brilliantly simple and possibly could be a useful mini project all of its own.

Very impressive build! At 8:25 there's a slight hiss at ~3.1 kHz but it might just be some electronics in your room. Either that or my it's tinitus 🤷

@DIY Perks I guess you could just put this mic in any land- and soundscape imaginable, record an hours' worth of content and upload it to a 2nd channel "ASMR Perks" or "Chill Perks" :'D Really enjoyed this vid.

I love this... This is SOOOOOOO good, but yet it has a few pet peeves I feel an absolute need to point out. Clearly, you have the electrical knowledge and audio engineering understanding to not only gut out 2 seemingly expensive mics [$200 is expensive to me, $400 for 2 is a nightmare] but to track down the right kind of pre-amp circuit and modify it for the phantom power requirement of condenser mics and to then manufacture that all together into a compact package and then shock suspend it in a cage... Yet it feels like you threw away all that intricate knowledge and attention to detail when you seemingly slapped together the PCB sandwich haphazardly and then made two half-assed screens for the mics and then threw everything else together with zip ties. I mean, don't get me wrong, this is well and truly amazing, hell you have a CNC router, I want to build a CNC router so I can do this kind of DIY stuff... You have all this knowledge and skill condensing into a product which is honestly the far upper echelons of what "DIY" usually constitutes an instead of pushing through with that attention to detail and product understanding it feels like you dropped your ability to care about what you're creating and went with the 'she'll be right' fit and finish of dodgy workmanship [the ground plate in the sandwich and the red mounting pads] and the use of zip ties for literally everything mounted to the birdcage and for the mics mounted to the circuitry... You have a fricken CNC bro, could you not design up and fab something moderately more elegant in a short frame of time? I mean, I love how you found a birdfeeder and used that as the frame, that's brilliant and elegant, but then you just zip tied your mounting plates to it and it's as though you just wanted to avoid thinking of a more 'finished' solution. But I get it, on one aspect a lot of these sorts of projects are perpetually a sort of prototyping phase which is never really re-visited and finished off and sometimes something ends up taking more time and effort (especially with me) than you had originally anticipated so you almost start cutting corners to just get it finished... But I don't know, it's like your idea was half a step away from genuinely being mistaken for a $1000 product but the tell of zip ties and chaotic vine wrapped wires on the birdcage are a kind of *tell* that this is just a really good DIY project... Zip ties as a fix all... I dunno. It's like DIYers that can't spray paint to save their lives and end up drenching the item in paint rather than lightly dusting it with numerous coats or DIYers who spray paint PCV parts with spray paint instead of vinyl dye (which is, pretty much all of them). It's like, 99% of the time paint is just used as aesthetic surface covering - almost always black - as opposed to a material protectant, which is what paint was originally for especially in the case of metal and even though the entire point of painting the DIY project (or in actuality drowning it in black spray paint) is to make it look professional/good and maybe make all the surfaces and mildly varying materials look more uniform so it looks like a professional *purchased* product rather than a junkyard DIY, they screw it up by painting entirely wrong. Painting small things is not hard and yet people almost always get it wrong and completely ruin the finished product. The irony is that most DIY stuff is either made out of or with PVC, made or modified from toys and cheap electronics and almost always made with plastic over metal, most certainly painted a flat black which is the easiest of all colours NOT to screw up... Yet everyone gets it wrong. The irony is that almost everyone is spray painting with paint and with terrible technique when there's already a product out there accidentally suited exactly for their purpose: Vinyl Dye. The irony is that vinyl dyes, originally for the purpose of dying the vinyl interiors (mock leather) of vehicles and to an extent, I guess any furniture/couches etc with vinyl, is an accidental exact match to all the needs of a DIYer. Vinyl dye, originally for dying vinyl fabric (arguably impossible to spray paint) is chemically 100% compatible with vinyl-based plastics, i.e. Polyvinylchloride aka PVC and it is also 100% compatible with ABS plastic which is ironically a very cheap and fairly durable plastic which is very easy to injection mold, meaning most consumer good especially as far as tech and electronics go, when made with plastic are made with ABS. Ironically, nearly 100% of the things DIYers touch are almost certainly chemically compatible with vinyl dye and luckily for a group which has consistently proven themselves pretty terrible with fit & finish and with painting, it's stupid easy and almost impossible to screw up. Granted, vinyl dyes get a bit technical and confusing when talking about gamut and pinpointing certain colours and there is a great amount of variation to the end product depending on what you're painting on (all PVC and ABS is pretty much compatible, but it's not necessarily going to be the same finished product) but when talking about the 'just paint it black' mantra of DIY then you literally cannot get it wrong. With vinyl dying there are no primers, no clear coats, no need to remember how many primer to top to clear coats you have done (obviously), no complicated drying times and humidity/temp requirements when painting as with paint, there's no intricate prep work and unlike any kind of paint on plastic, even marketed "plastic paints" or "plastic dyes" you work ever get scratching, chipping or flaking of the paint with vinyl dyes. Only vinyl dyes can (accidentally) accomplish this holy grail purpose of being perfectly suited to something completely different to its original intent and being so perfectly (and accidentally) tailored to the requirements of such a large potential user base. Paint is very finicky and even if you follow the steps it may still not work out. With vinyl dye, all you have to do is scuff up the surface lightly with steel wool or sandpaper, if there's paint already over the plastic it needs to be sanded back to just the raw plastic. Vinyl dye seeps into and stains the plastic rather than simply putting a coat of paint on the top so if there's paint or a finish, the vinyl dye will chip and flake but if you sand back to raw plastic it will stain and dye the surface. Then, clean the plastic surface with a mild detergent (like soapy water with a dish detergent) to clean up all the potential residues off the plastic then rinse it well and dry it. Unliking with painting this prep isn't rocket science, it's literally like washing a plastic bowl in the sink, just wash and rinse it well and let it air dry completely. Then simply spray very very light even coats of vinyl dye and wait a solid 20-30 minutes making sure each coat is dry. 5 coats are probably plenty. Once you've done it once and realised that any un-painted/coated PVC or plastic can simply be scuffed up quickly, washed with dish soap and then painted plain black with the absolute minimal effort (vinyl dye spray is roughly the same price as paint, and you don't have to buy primers or clear coats too) then you realise how heavily the DIY community could benefit from this info and from ditching duct tape and zip ties as a primary form of construction... Seriously, does my head it, so much DIY is shit purely due to crappy paint and zip ties. I digress... This was actually awesome and I really really want to make one now that I've seen it can be done well and that it creates such and awesome final product I'd just also really like to see you go back and 'touch it up' to make it perfect.

This is a very cool project but it is very complicated for beginners like myself. something more practical would be like this example. I bought a Bluetooth to FM radio transmitter device for my car. It works ok but when I use to make a phone conversation, the MIC is so terrible that no one can hear me and I end up just using speaker phone feature. but I was wondering if I can replace the MIC somehow. Can I replace the MIC on the device? is it even possible?

If you ever decide to do another build similar to this, I would recommend using 2 omnidirectional microphone, and add some mass in the middle. The overall goal would be to make a binaural microphone, meaning a microphone that can pick up perceivably 3D sound.

How did you get the 48V for the NT1A's phantom power? Or are you running them @ 25v? And how did you get the dual supply required for the preamps? Two LM2577s? A second rectified capacitively-coupled output from the boost converter? Virtual ground? I'm just curious, this microphone performs pretty well :)

Hi there, really love this project of yours. I just wanted to ask if you could provide the schematics on how you connected the two microphones together, apply power to both, know if each has a pre-amp circuit and how you mixed them both to create a stereo output to the recorder?

Just fantastic.... Imagine if you mass produced these... Being new to audio recording I am a little excited as my second 'second hand' large diaphragm AKG SL mic is on it's way in post.. I don'y have a portable recorder but I do have a Mobile Pre (Older model) and my old XP laptop has great battery so I will be mounting the two mics like these in a furry cage ! I have already tried recording outside using laptop and Mobile Pre in shoulder bag with mic in hand with no problems except I will say it's awkward and a bit heavy ! So if you can afford a recorder forget dragging. laptop and USB interface around....

Oh - Change that TL071 for a TL072, higher quality. Also, solder the chip in, those chips sockets are great for digital but oxcidise and drop in sound quality over time. Also, why do you need them - are you going to change the chip ever? :o)

While I do very much enjoy hearing you say "Aluminium," I still have to dislike, as this is NOT a DIY *Microphone,* it is two commercial microphones and a preamp, with a battery-pack and a portable digital audio recorder. Sorry, but bad title, as you did not build a condenser mic from parts or even from a kit, you just put two NT-1's inside a piece of luggage with the rest of the equipment conveniently mounted in a single ....... uh, pocket-book. Very useful, but mislabeled. Try searching youtube for "DIY Microphone" and see what comes up. It's usually an actual *microphone* that the uploader did him or herself, hence the "DIY" being in front of the word "microphone." This is a "DIY Mobile Recording (rig, outfit, setup, etc)."
