Are you sure your sound card did not affect the recording of the diy mic ? Because the studio mic has an integrated sound card that might be better than your computers internal one!

[@INeedAttentionEXE]

Maybe, maybe not. A lot of modern computers have great audio codecs that can be just as good as a usb microphone or its studio XLR counterpart. This discounts the fact that XLR is a balanced signal and usb is digital.

[@scivirus3563]

I would not use USB for voice over and sure as hell not a standard soundcard.. Dude it will never get as good as an XLR. Because of signal to noise ratio

[@lanchanoinguyen2914]

you're right,but i doubt the point that the studio microphone was invested too much in the the ADC chip.Because the microphone by the way has to be connected to a dedicated audio interface before the computer.

[@sophiophile]

@@INeedAttentionEXE No matter what at some point the analog signal travelling along the XLR cable will get digitized for use on a computer. And so having it built into the mic means there is no cable length for signal degredation (you can think of the USB mic having a XLR cable length of nearly zero, assuming it's balanced circuit topology)

I think this test is unfair. Electret microphones needs some housing to avoid the "echo". To make it somewhat similar, I at least would put the band-pass filter in the condenser mic.

Hey greatscott maybe you can make a diy or buy episode about lipo balance chargers, or even a episode on how to build them. Because there are not a lot of diy lipo balace chargers on the internet and buying one is a little bit expensive. Besides that, if we know how to make it we can make more safe battery packs in our diy devices, for instance: make an electric longboard with batterypack and built in charger so you only need to plug in an adapter and dont have to plug the bttery out everytime you charge or have a less save batterypack with a bms.

So that's what phantom power is about when talking about mics. I had always wondered. I assume the music was from audioblocks?

[@greatscottlab]

+Wholly Mindless Correct

[@simaorodrigues6285]

[@elaquen7]

+Senpai Kur I think Patreons get to watch videos earlier than others.

[@boblewis5558]

Well actually no! Phantom power is indeed usually 48 volts but it requires the use of a microphone transformer at each end of the microphone cable. Some early high quality mics like the AKG c451E (STILL sold today, unsurprising really as it's a superb high quality mic, yet I was using this exact same microphone in 1971!!) used (uses?) a separate power supply for ease of use where phantom power was unavailable from the mixing desk (where it usually is derived or supplied). The subject is an interesting one and worth checking out on Wikipedia. Much has changed in the industry since my first job as a professional TV sound engineer after graduating, but phantom 48v power and microphones fed from it are still around and old (1970's) microphones can still be used seamlessly in modern studios or on stage rigs without problem - witness the c451E mic already mentioned. Because true phantom power requires 3 wires (2 for balanced audio and the positive 48v feeds plus an audio return) it integrated, and still does, very nicely with the ubiquitous ITT/Cannon 3 pin connectors seen on all professional audio equipment since before I was a boy. Where a 1/4" jack plug (6.35mm) is used it is NOT a balanced feed and in this case in order to provide phantom power a separate power supply will be used that has a built in transformer of appropriate type to which the two-core screened and balanced mic cable is attached (implies that you MUST have a balanced microphone at the other end or an equivalent adaptor from single ended to balanced feed) and which also provides an unbalanced output to connect to the mixing desk. Check out the Wiki, but also bear in mind that POE in the IT world is also a phantom power scenario and utilises the balanced signal transformers contained within modern (relevant ones) Ethernet RJ44 jacks. The separate POE injector units you can obtain do the exact analogous job of the separate 48v phantom feed units in the audio world. BOTH use 48v, 24v and 12v within the standards and at a basic level work in EXACTLY the same way - providing noise rejecting remote power to devices along the signal cable

[@TrollFaceTheMan]

Phantom power is just electricity that is needed to operate the microphone. It is a DC signal that is then converted into sound waves by the difference in capacitance between the two plates.

[@cummins6945]

You could have also replaced the usb port!

[@greatscottlab]

True, but that would have spoiled the fun of playing around with electret mics.

[@calyodelphi124]

Interestingly, I'm doing a mix of DIY and BUY with my mic. Few months ago I bought a Neewer NW-700 mic kit (comes with a mic, phatnom power supply, XLR cable, XLR-phono cable, boom arm, and pop filters all in a USD$60 kit), but I completely forgot that analogue condenser mics produce signals only a hundred or two millivolts strong. So I'm intermittently (when I can motivate myself) DIYing a pre-amplifier to boost the mic's output for recording. And mostly using jellybean components. The op amp I'm using is the LM324 quad op amp, with two utilized for the left/right channels of the mic output, and a third acting as just a voltage follower to buffer the 2.5V DC offset for the other op amps. I'm at the point where I just need to breadboard it and test it out to make sure that it works like it should. :)

[@classicksam7366]

Hey, maybe you can make a small surveillance system (camera and network to connect to phone) for your shed? Using a camera and seeing whenever someone is in the frame of the camera. Also you can have it notify you if there is. You can compare a DIY or whether to buy it.

[@jeffspaulding9834]

If you go to woodgears.ca, Mattias Wandel has some software a a video or two on something like that up with a Raspberry Pi. He used it to monitor a mouse trap and a maze. Go to wooden machines & contraptions -> Raspberry Pi holder and scroll most of the way down (he's a woodworker, but he was an engineer for RiM so he does some electronics as well). You'll still need to connect it to a network and set it up to notify your phone, but that's more of a networking thing than an electronics thing.

[@Barbaratio]

Actually, your PC also uses an ADC, sound card or on board audio, they both use an ADC

[@sucotronic]

The problem is that he is comparing a commercial capacitive mic with built in ADC with a capacitive mic connected to mic input. To be fair he would use an external usb ADC chip in conjunction with the electret mic in the comparison.

[@RadOo]

Using built-in ADC has one disadvantage, the audio is polluted with noises from the power supply, external for example USB ADC regulate the voltage and you'll get lot less notice from it 😉

120€ gives you a DIY kit that already kinda works - you can't beat it price wise even just for the parts cost, and if you decide that it's not good enough, you already have 5 actually very good quality motors, a decent if somewhat exotic and undocumented board, a good enough hot-end that can do massive temperatures, and lots of other parts which are honestly not particularly good (feeder, heatbed, mechanicals) but just about work, so perfectly suited for modification or rebuilding. And the frame is from melamine plywood, so you won't ruin it by drilling some new holes into it. It's the CTC i3 Pro B that you get on eBay, and the EU import tax on it has already been paid by importer.

I would like to see a video on shift registers. Never fully understood how they worked or what purpose they served.

[@greatscottlab]

I put it on my to do list

[@bansheedearg]

They convert serial to parallel and vice versa. Like a hard drive, SATA, will spew bits serially and it uses a shift register to load up 8 bits or 32 bits or whatever. Likewise you have a 32 bit word and you want to write it to disk, you have to serialize it, so you shift it out one bit at a time, presto parallel to serial. Smart LED strips are like a shift register, you load the colors serially and then see them all at once (parallel). That might be a fun project, 3 wires (clock, data, ground) to a shift register and 8 outputs to LEDs so you have your own smart display.

[@williamzacharias624]

Sean Brennan So how could you use it on a serial LCD? I saw a video of someone use a shift register to reduce the number of wires from 12 to 5 going into an arduino without explaining what it did, or even what wires go where.

[@bansheedearg]

He probably had a parallel LCD, which wants 8 bit commands. Instead of using 8 data lines, he used 2, one to clock in data, one for the data itself. So he would clock in 8 bits to make a byte, then tell the LCD to execute the command. Nowadays you don't really need parallel devices and can go straight to I2C and use libraries. The other lines were probably ground and enable or some such.

[@williamzacharias624]

Thanks for a great DIY project. The microphone delivers good audio for its price.

[@KnightsWithoutATable]

Op-amps NEVER produce faithful amplified signals. They ALWAYS distort analog signals, even if they claim to be 'designed for audio amplification', because they amplify signal at varying levels depending on their frequency. Use op-amps for low quality audio applications, single frequency applications (like RC control signal boosting), digital signal boosting at low data rates, or a few other applications they are useful for. A higher quality audio amp used instead of an op-amp would make a huge difference. This would require a powered circuit and increase the bulk of the design, but we are talking about studio sized mics, so that is no problem. You could use a high quality IC amp made for audio or a set of JFETs with accompanying components for the audio amp section. A minor change to the circuit with minimal cost for the IC option and there are several that would work well. There were 2 mistakes in the design that also effected the quality of the audio. First, you need a few noise floor filters to remove inherent noise in the circuit and any light background noise. This can be done with op-amps in the correct configuration or by discrete parts. One goes between the mic and the first audio amp stage, in between any other amp stages, and one right before the output. This will do noise reduction in the entire circuit and keep the amps from raising the noise floor. Second, your band pass filter was at the wrong frequency ranges. You used the range for the human voice's primary frequencies. This works fine for a telephone call, but it cuts off resonant frequencies that add to the sound of the human voice and music. 20 Hz to 20 kHz is the hearing range of a young, healthy adult. Mics like this can have problems picking up both very low and high frequencies, but for voice it is not really a problem. Music is a different story. A bandpass filter set to 20-20k Hz right after the noise filter at each stage and the initial would be the best filtering solution. You do not need one on the output since the sound card has a bandpass filter built in. There is also the consideration of what your sound card had for the sample rate on its analog to digital converter. This can make a massive difference on sound quality. The USB studio mics would have a very high and high bit-width output from theirs and would have told Windows through the USB connection to use the correct sample rate. Many sound cards built into motherboards are not of very high quality, but there also is the possibility that Windows defaulted to a low sample rate. Go into the mic properties and try turning the sample rate up.

[@hanelyp1]

Ideally the feedback network sets the frequency response of an op-amp. And if the signal is within the chip's capabilities it works that way. But given real world op-amp characteristics, a circuit may do very well at lower frequencies but struggle to keep up with higher frequencies. It sounds like he needs a faster op-amp for his microphone.

[@lordjoshuarobindumbleton275]

Google 'Unity Gain Bandwidh Product' please.

[@researchandbuild1751]

I dont see how you can reduce the noise floor by adding even more components. I think the only core problem in his circuit is the filters. It is cutting off a lot of the low end and that why it sounds like a telephone. Most likely its the electret microphones frequency response that is the issue, not the opamp. Ive used low noise opamps before (-100db noise) and they always work great. Also, the electret has to be in a decent housing to focus the audio waves

[@ninovitaliano7943]

THIS IS THE LONGEST. COMMENT. EVER

[@BillAnt]

The op-amp can be configured for a noise level threshold cutoff, therefore it will not have an output unless the signal level reaches a certain predefined level/frequency. Course the flip side of this is, that it can clamp certain levels/frequencies and will never sound as good as a professional mic. It's called poor man's DIY mic :D

If you compare to the original Arduinos (now called Genuino here in Europe), then it's definitely a win for the DIY, since an -Arduino- Genuino UNO costs 20 € + shipping (which is very expensive, 10 € minimum to Spain). If we compare to the clones, then it's definitely a win for the buy, since they're only 4 € and free shipping. The only downside is the time they take (minimum 1 week).

[@Teth47]

Well if you're starting with a 16/32 pin DIP package all you need is power, a USB FTDI controller if you're programming it that way, and a pin breakout... Almost guaranteed that buying an arduino is cheaper, unless you're getting the super expensive ones. You can get a Pro Mini for like a dollar or two.

Julian Ilett has actually done a video like that: kzbin.info/www/bejne/qX-sfnaai7R7ha8

How about a Diy or Buy Episode on bright 18650 powered flashlights with an Output of 350-1000 Lumens?

[@someguy3054]

Makersteve YT possibly buy as making a flashlight that powerful could pose challenges

[@stevenjohn7770]

Some Guy Not really. These Led-Chips are very common nowadays having a light output of roughly 100 Lumens per Watt. To build such a Flahlight, you really just need a boost converter with constant current feature, which he already build, and a charging/protection board for multiple cells in series. These are also not really expensive to get. Apart from that, there is basically just a housing + heatsink + swich needed.

I like this series a lot

[@georggross1232]

Now that you did this video, I'm definitely thinking of my voice acting practice and performace: I AM SCREWED!!!

[@yvonnemerita388]

how about building your own MP3 player?

[@greatscottlab]

I put it on my to do list

[@zuryan]

you can get a battery powered MP3 player for 1€ off ebay. it would be an interesting project though

[@jonetech5324]

GreatScott! You could add a touch GUI

[@Mrengineer1]

GreatScott! Your Work Is Awsome I like Your Voice....

[@Isolierter_Hazim]

I am about to ask the same question....

[@DZ_Technovation]

Please give us a PCB card

[@kenya_3364]

Thank u so much man! Cuz of u I made a mic preamp and it almost costs 1$ and it sounds good enough for normal use 🙂

[@oggamez5735]

I used the LM386 audio amplifier, and when I played it through the computer, it sounded almost exactly as I would hear my voice when I'm talking.

[@andrejlacko1870]

can you make next video DIY or Buy with remote control car ?

[@melihspots7939]

Andrej Lacko probably Best to buy one you Can modify. If you see This. Serch for tamiya or HPI or kyosho. Then you Can continue

DIY or buy crippling depression

[@petersage5157]

I stumbled across this video while looking for DIY intercom systems to aid in communication across Perspex barriers (COVID-19). Since the cheapest electret mics have peaks that emphasize articulations in human speech, it's clear that these are better suited to my purpose than large diaphragm condenser mics, especially in an environment with a lot of background noise.

[@ducamvinh4462]

This is very cool, a project with a kind of practical use, made from basic filter op amp circuit I just built it, but has a ton of noise, i had to put it inside a box to eliminate the noise

[@juanchaves1224]

Buy or DIY a baby?

[@lucasc5622]

You can get one from the dodgy guy in the alley

[@byteofwood]

Diy 😏

[@liveleaky7571]

Jacob Wood oh yeah

[@liveleaky7571]

H3000 oh yeah

[@stormtrooper8470]

Have you tried to raise a child

[@mathix420]

Diy or buy a drone

[@byteofwood]

Buy

[@mpcrazyscience7097]

diy

[@ShaunHusain]

Absolutely diy... Buy a cheap one to learn then build a 250 because you will be rebuilding it at some point. DJI and the like are a huge rip off.

[@Erowens98]

Diy for sure. Diy is the way they've always been done (pretty much the entire rc aircraft industry has been diy for decades). The models that have become mainstream have become mainstream due to marketing and ease of entry, but are not superior to their diy counterparts. Anyone comfortable with diy should diy. On a side note, they also make an excellent father-son project, i remember building my first diy rc helicopter with my father 13 years ago and honestly, it was one of my best experiences with him. Just enough challenge to make you think, but not enough to be frustrating.

[@someguy3054]

Shaun Husain so youre telling me that a well known brand such as DJI is a scam? Please elaborate as if memory serves you cant get a motion controlled drone that works without paying much of a premium. Would like to hear your thoughts on that

[@ajnsztajn2841]

U are a God in drawing understandable schematics. Seriously

[@jolex_nerd8132]

As you can see, adding 5v to the mic gives low voltage. Can I change component values or higher voltage to get more signal? I want to plug mic’s to a “DJ” mixing thing I got as a present, to use for my drum set. I heard RCA signals are 1-2 volt.
