Thankfully, you're super-smart and always use a breadboard to prototype your circuits. :) I have a pair of studio reference phones I want to try this on. Great video. And it's open source!
For your studio reference headphone you may want a better Bluetooth CODEC and a better DAC than this board supports. It may be possible to get LDAC on this but I suspect not. Probably easier to buy a ready made product if you are looking for good quality audio
What you could do, instead of putting that bit of extra weight into the headphones, (and possibly damaging them to make things fit) is make an up to phone sized module that hangs round your neck, maybe under your shirt, maybe in "landscape" rather than "portrait" orientation, for stability. Make the case according to what the electronics and battery will require (so you could have much better battery life - maybe even make that extendable just in case.) Benefits of doing things this way is that you don't mess with the balance etc of the headphones, as-designed. (You just need a nice broad neck strap so that it doesn't cut into one's neck if some variants - the 20 hour battery one, for instance - get too heavy.) I often wonder why designers of head-wearable kit (eg. VR goggles) insist on putting more than the bare minimum in the head mounted part. Surely the best place for anything that weighs anything is as close to one's torso as possible? (As close to the centre of mass, even.) So you're actually done, then. The unit is already plenty small and compact enough for neck- hanging.
interesting points, we have adiscussion going on the Element14 community page for this video! if you want chime in and maybe this gets towards what you are envisioning!
@@MAYERMAKES Hi, I've checked out the community page, and it looks lively and interesting. Unfortunately I have a quite "occasional" interest in this kind of thing, and more of a "what's up in that world" than maker interest. Basically, I've seen good content on your RUclips channel at some past date, and thought it looked worth subscribing, but it's been a while since I last burnt myself with a soldering iron. At this stage I don't think I should open an account there, just because there's a chance of it becoming yet another one of my unmaintained online accounts - not a good idea to have too many of those (or any, really). But thanks. I'll keep it in mind, and if my circumstances change (not impossible), I'll remember, and go and join in actively. For now, though, I don't even often have what seems to me a good enough idea to be worth suggesting, and my visits are a bit sporadic. Your videos are great, B.T.W. !
Yes! I have been putting off a project for too long. Converting a dehumidifier to a smart humidifier. Basically hijacking its control board and ether replace it with my own or just hijack the screen and buttons to put a device in the middle.
Of course, there are lots of tiny and cheap Bluetooth audio receivers that can instantly turn any wired headphones into wireless (many of which have a switch to also act as a transmitter), but where's the fun in that? The other advantage, though, is that many of those also have a built-in microphone so they work as a handsfree for phone calls.
there wil lalways be a cheap otpion for most stuff, but do you have control over them, do you really know what its doing , with your data and your devices? Nobody should have to trust anyone,but be in control of everything they own. I think its not a bout building a cheap option but a Free one as in Freedom.
Hey there Clem, Please when able make a video on programming the ESP32-Wroom bare bone using EVA foam and sewing pins. I'd love to see your approach to this unique problem. I do not want a break out board. I do however need to program the ESP32. Think EVA foam and sewing pins can do it?
I2S is serial like SPI, but applied to PCM audio mostly. There's a doc from Phillips that really breaks down the spec into easy chunks to understand. At first I was thinking "why would ANYONE do it this way?" but it really makes a lot of practical sense. And the "nein, nein, nein!" moment caused me to spit coffee out my nose! :D
Coffee ejection accomplished. Thanks for the insight! YT doesntvlike links but pur community page does, so in case you would like to post the doc , it would be appreciated! Thanks
Could the ESP32 support 24 bit audio at 96kHz or higher? Would be interesting to implement HD audio over Wifi, similar to Nvidia's implementation (for the Shield TV) except it would work with a regular PC.
Hey, this was an amazing video! The editing back in time had me laughing away. I'm looking at doing a headphone project and going above and beyond the level of my other projects. I really want to do active noise cancelling which led me to Qualcomm chips. From what I can make out though you have to buy the ANC features as well as the chip itself and to do so you need to be a registered business! It seems a bit of a mine field. Would you have any suggestions for a project with ANC? Would it be possible on an ESP32 or maybe there is a way to use the Qualcomm chips which will probably give the best end product.
I found the video fascinating and would love to replicate the circuit on the breadboard, but I'm unsure about the specific wire connections. Could I kindly request your assistance? I'm new to this field, and I'd greatly appreciate a detailed explanation of the connections on the breadboard or perhaps a clear visual reference.
I'm still getting 404 error, I tried on mobile and desktop. Same error also using a VPN. I'd really like to adapt this project to convert my Beats EP to Bluetooth. Any direct link or other ways to access the file? Thanks
If you happen to know more about I2S please post on the community page for this video, as we can exhcange pics and so on alongside it. Iḿ sure Iḿ not the only one interested!
@@MAYERMAKES Sadly I have no practice with I2S. But there are a lot of good videos on youtube (greatscott, Andreas Spiess, DroneWorkshop ..) about I2S practice. A try to link one of them: ruclips.net/video/a936wNgtcRA/видео.html&ab_channel=AndreasSpiess
yeah who would buy that? or an mp3 player that only plays music purchased from one store, or earbuds that only connect to one brand of phone...well some people do. and they need a free option.
"Nein, nein, nein, nein!"
I choose to believe this part was actually dead accurate.
that is more real than I like to admit.
That was my actual reaction and same reasons hahaha
Agree 100% we should control the things we own (and also be able to fix them so they don't end up in landfills) #RightToRepair

I wish I really was but thanks to editing magic it worked out.

@@st200ol we all ahve to start somewhere, would be great to one day achieve true studio quality.
Great video. I like that you showed what goes wrong because you learn a lot from that in prevention.
yes, I think that is actuallythe interesting part. the pitfalls.

@4:00 ja Prototypen sind immer eine gute Wahl. ;)

This is my favorite youtube channel
Thank you
Yes!

how would one go about doing this themselves? im not an expert with coding but im good at soldering and thought i may give it a try if i knew how
follow the link in the description everything you need can be downloaded there
is there a dumm dumm version without sodering? just stikcking and glueing?
Our latest video might be exactly what you look for.
Demo of the module version at @7:45

deine Videos werden immer besser - und unterhaltsamer (technisch fundiert waren sie immer schon ;-)
Danke sehr! Aber ich glaub beim technischen hab ich mich auch langsam verbessert, man lernt nie aus.

Maybe .?
I live in fear of getting the 🙄slightly wrong part.
you merely adopted the fear of wrong parts, I was born in it , molded by it....
I like the idea! What about Headsets? That would be cool!
Sure, why not.

it seems that all of the code for the prototype is gone from the website.
its all there when I follow the link. should be good.
Nicely done.
thanks!
I certainly wish my Foldio360 was open source!
I had to google waht that is, if you would like to see such an episode, make sure to leave a suggestion on our community page!
Great 👍 love your work 👏
thx
Nice project 🎧
thanks
Dude, thank you so very much
Any time
you are welcome
I had that happen when ordering a atmel328p.... i ended up with atmel328pb.... slightly diff pinout
ah we have all been there, i wish some more differentiation would be made on MCUs part numbers
make 2.4 or 5ghz audio transreceiver
yeay
wow
an opensource smartwatch
i think thats a good idea do you want your health data controlled by some big corp like uhhmmm lets say google
Turn it up to Nein!
Ic to Ic sound
Very nice project! I'm getting 404 on the link to the download of the files though
please check again and let us know if you have issues - just rechecked and everything appears to be working
I'm still getting 404 error, I tried on mobile and desktop. Same error also using a VPN.

Okay, we'd need to see what link you're exactly trying to view. Would you mind posting to our support section on the site? bit.ly/3IFs1cg
i thought i2s was closer to spi than i2c
lets discuss that on the community page with pics and links and stuff, should be interesting
i2s == Inter-IC Sound acording to wikipedia
but the bus definition docs do not call it that...its a weird case of could be.
I2S is more like SPI.
